The priority of these prior applications is expressly claimed and their disclosure is hereby incorporated by referenced in their entirety.
- The present invention relates to tissue retractors, for use in medicine. More particularly, the present invention relates to fluid operated apparatus for use in moving apart abutting tissues, during surgery, in order to creates a space between the tissues to improve visualization and for increased working space during open surgery and fiberoptic assisted surgery.
- Current methods used for retracting tissue and improving visualization are mechanical separation using metal retractors during open surgery, or the direct pressure of an unconfined flow of fluid such as water or C0 2 during fiberoptic surgery. A typical mechanical external fixator has pins driven through the bones and mechanically distracts the elements of the joint. Problems with the water method include fluid extravasation including into and through the tissue itself. Increased pressure and swelling result in the area, resulting in edematous or swollen tissue. Excess pressure from mechanical retractors may cause necrosis or tissue death. With these methods, it is impossible to monitor the pressure being applied to the body tissues, and tissue damage or necrosis can result.
- While operating from within the body, i.e., fiber optic assisted surgery as opposed to open surgery, there is no known way to selectively move or retract tissue, either hard tissue such as bone or soft tissue, out of the way to improve visualization. No device in use adequately allows a surgeon to create an actual space or expand a potential space in the body, by separating adjacent layers of tissue. The prior art does not disclose a retractor that is powerful enough and made of a material that is strong and resilient enough to, for example, separate tissue planes from within. Such a device, especially in the field of fiber optic surgery, would allow a surgeon to visualize and operate without using the conventional bulky and awkward mechanical retractors that require large open incisions. Such a device would also permit working within the body without damaging a great deal of tissue in the path between the skin opening and the working area, by minimizing the external orifice or skin incision.
- The present invention is a system of retractors that a surgeon can use to take potential spaces within the body and turn them into existing spaces safely and easily and controllably in order to safely visualize appropriate tissue and operate. The retractor selectively moves appropriate tissue out of the way to enable a surgeon to see and work better within the body, and selectively moves body parts such as joint parts or soft tissue planes in order to create a space between the tissues for visualization and for working.
- The retractor of the present invention includes a fluid-operated portion such as a balloon or bladder to retract tissue, not merely to work in or dilate an existing opening as for example an angioscope does. The fluid-filled portion is flexible, and thus there are no sharp edges which might injure tissue being moved by the retractor. The soft material of the fluid-filled portion, to an extent desired, conforms to the tissue confines, and the exact pressure can be monitored so as not to damage tissue. The expanding portion is less bulky and more compact, and the pressure it applies at the tissue edges can stop bleeding of cut tissue. These are all features not possessed by a conventional mechanical retractor.
- With a typical mechanical retractor, the opening in the skin and thence inwardly must be larger than the surgical area being worked upon, in order to be able to get the mechanical retractor into position. The surgeon must damage a large amount of tissue that may be healthy, in order to expose the tissue to be worked on. The retractor of the present invention minimizes damage to tissue in the way of the tissue the surgeon needs to expose, which was previously cut in a large open exposure. With the retractor of the present invention, the opening at the skin is smaller at the skin where the device is inserted, and wider at the location inside the body where the retractor is expanded. The retractor is first placed into the body in an unexpanded condition, and then, as it is expanded, pushes tissue out of the way in deeper layers of the body one can see and safely operate on affected tissue. Thus, less undesired tissue damage occurs.
- The bladder is pressurized with air or with water or another fluid. The fluid used in the bladder must be safe if it accidentally escapes into the body. Thus, besides air, such other fluids as dextrose water, normal saline, CO2, and N2 are safe. The pressure in the bladder is monitored and regulated to keep the force exerted by the retractor at a safe level for tissue to prevent tissue necrosis. The retractor can exert a pressure on the tissues of as high as the mean diastolic pressure of 100 mm of mercury, or higher for shorter periods of time, while still being safely controlled. Typical inflatable devices such as angioscopes do not have anywhere near the strength, or the ability to hold enough fluid pressure, or shapes to retract tissue as described herein. As compared to prior art devices, the retractor of the present invention operates with greater pressure within the bladder, since it is made of stronger materials such as Kevlar or Mylar which may be reinforced with stainless steel, nylon, or other fiber to prevent puncturing and to provide structural shape and support as desired. Such materials are strong enough to hold the necessary fluid pressure of about several pounds or up to about 500 mg Hg or more and exert the needed force on the tissue to be moved. The choice of material is well within the ability of one familiar with such materials and accordingly will not be gone into in further detail herein. The present retractor is thus able to exert substantially more force on adjoining tissues than a prior art device. The shapes of the retractors are specific for each application, and may include separate variable chambers which are sequentially controllable, to control the direction of tissue retraction.
- The fluid-filled portion of the retractor is preferably a unitary portion such as a bladder. In this case, the bladder is expanded with the introduction of fluid under pressure. Alternatively, the fluid-filled portion of the retractor may include a series of prongs or filaments that expand radially outwardly upon the introduction of fluid under pressure. The prongs themselves may be expandable, or there may be an expandable portion located centrally of all the prongs which, when it expands, forces the prongs outwardly.
- Typically, the height of the bladder, that is, its width or transverse dimension, is significantly greater than its length (axial or longitudinal dimension). The bladder expands primarily in width only, not in length, although the shape will vary with the application.
- This is in accordance with the purpose of the device which is to enable the separation of adjacent tissue layers to, for example, allow improved visualization in front of a scope inserted between the tissue layers.
- The retractor of the present invention can be used to direct or position the end of a scope relative to the tissue walls. The retractor can also be used to stabilize the end of a scope. When a camera is being used via the scope, the scope often moves or jumps around because of the flexibility of the end of the scope. This is prevented by inflating bladders at the tip or along the shaft of the fiberoptic scope to control the direction of the tip of the scope and thus stabilize the scope, leaving both hands free to work and providing a stable image for the surgeon.
- Surgeons operate along tissue planes. Once a surgeon finds a tissue plane, he dissects along it, starting the separation process with the knife. The retractor holds the tissue layers apart and helps and eases in defining and further separating the tissue layers as the surgeon operates along the tissue planes, helping to spread and define the planes. The retractor helps to separate the tissue layers, increasing the space for operating, and improving the surgeon's ability to separate and visualize, leading to better and safer surgical technique.
- A preferred use for the present retractor is in the field of fiber optic surgery, including endoscopy, arthroscopy, laparoscopy, etc. which require looking into and operating within a limited space with a fiber optic light and camera. The open or existing spaces in joints are generally too small to permit easy operation and visualization. In the Prior art, only direct (unconfined) water or air pressure is used to expand the joint capsule or tissue in the joint. This may actually push tissue in front of the scope, obscuring vision. The present retractor distracts a joint directly to make it easier to see inside (around) the joint. A sleeve which can be a malleable or rigid sheath may optionally be provided to protect the tissue as the bladder is slid in and out of the end of the cannula once in the work area within the joint. The bladder expands into an area of soft tissue—for example the bursa—and pushes it out of the way. The bladder can be left in place during the operation, or it can be deflated and removed, and the arthroscope and other instruments can be put into the space created.
- An alternative preferred use for the retractor of the present invention is to operate in a joint of the spine, and specifically between two vertebrae. The retractor is used to spread two vertebrae apart to enable removal of the spinal disc from between the vertebrae.
- Other uses of the retractor are as an occluding device to stop blood flow from an anastomosis or angioscopic procedure, or to stop backflow (retrograde flow) of stomach or colon contents. The retractor of the present invention is also suitable for use in the tempomandibular joint. Specifically, a dentist or oral surgeon uses an appropriately shaped retractor to hold open the jaw of a patient while the dentist or oral surgeon works on the mouth of the patient. The inflatable retractor is much more comfortable to the patient than a rigid metal or plastic device, it conforms to the jaw structure rather than pressing unevenly against it, and lessens fatigue. Thus it is safer for the dentist by safely maintaining the two rows of teeth spaced apart and by increasing visibility for working, while at the same time being easier for the patient.
- The retractor can also be a useful diagnostic tool. The strength or pressure or resistance of tissue can be measured by the pressure required to move it.
- The bladder may be a bellows type device in which the material does not stretch but which expands when pressurized from within and which is collapsed by the use of suction. In this case, it would preferably be made of a polymer of the class including Kevlar or Mylar fabric for strength and structural integrity. The bladder may generally also be made from any very thin walled polymer.
- The bladder may also be made from a biocompatible and/or biodegradable material, so that if it can not be removed from the body for some reason, or if the surgeon desires to keep the bladder in place in the body for a period of time, it will not damage the tissue and may eventually be resorbed into the body. Such a biodegradable bladder may be left under the skin postoperatively to stop postoperative bleeding or to keep tissue expanded. Alternatively, the bladder may be made of a stretchable material which stretches when pressurized from within, and then collapses partially of its own accord when depressurized or also with the help of suction. The retractor may be transparent for better visibility, but it need not be for some applications. Also, the retractor can be disposable. The material choice is within the skill of the art. One surface of the bladder may be made of or have thereon a reflective surface to reflect light to see around a corner.
- The retractor can be used as a joint jack—that is, to distract a joint from within in one area and provide ease of access through the joint. Less damage to the joint occurs if the tissue edges are spaced apart during a procedure. When placed between two joint surfaces it pushes them apart from within, increasing the space available for visualization and/or the working space. The retractor stabilizes a joint when expanded because it forces the tissues to remain in one place.
- Another use is to look directly at a neurovascular bundle, retract it out of the way, and then operate around it. For example, the surgeon can go into the back of a knee, inflate the retractor, identify the neurovascular bundle and then be able to work around it. The task is made easier by the ability to separate tissue layers from within. One may cup the tissue then push it out of the way, in the nature of an umbrella opening, to protect vital tissues to operate safely around them.
- Depending on the application, the retractor can be left in place while the work (or looking) is being done, or it can be deflated and then taken out to allow a scope or other instrument to be put in. Some tissues will stay in place to allow this latter function, after the space has been created with the retractor.
- A most typical construction for the retractor of the present invention is an inflatable bladder situated on the end of a shaft, which may be flexible or rigid, which is pushed through an extra opening in a scope or cannula or through a separate portal, and which expands at the end of the shaft.
- The retractor can be located on a scope, either on the end thereof or movable axially through a channel along the length of the scope. The retractor can alternatively be mounted on a cannula. The retractor can be mounted on a separate shaft passing through an existing channel in a cannula; it can be inserted through a separate hole in the cannula or the scope; or it can be inserted through a separate opening in the body. The shaft with a retractor on the end can be pushed or slid through the cannula, side by side with a scope. Alternatively, the bladder can expand out of, then recess back into, a groove on a cannula or scope. The retractor can be used to create a space right from the end of the scope.
- The bladder itself can be round, eccentric, oval, conical, wedge-shaped, U-shaped, curved, angled, or it may be in any shape desirable to optimize the particular application. The bladder may be irregularly shaped when inflated, that is, it may expand to a greater radius in the area where it is desired to look (where greater exposure space is needed).
- Vacuum can be used to deflate the bladder. The bladder may then be removed by sliding it out the portal directly.
- In one embodiment the retractor includes a spring loaded sleeve which slides axially over a plurality of plates or prongs, plastic or metal. A centrally located motive force is provided to move the prongs outwardly to retract the tissue, which force may be mechanical or a separate inflatable device. Alternatively, each filament is a tube which expands and straightens out as air pressure is added (as it is inflated) and thus moves radially outwardly to retract adjoining tissue. The filaments plates or prongs are controllable and covered by a sheath, which slides off them proximally axially to allow them to be inflated and expand, and then, after they have been deflated, slides distally along the shaft over the filaments to cover them and allow the device to be moved through the body. When the sleeve retracts the prongs or filaments expand radially outwardly to push tissue away from the scope to improve visualization.
- The retractor can be disposed at the end of a flexible sheath. The retractor can be directable with cables, or with compressed air, to turn or bend in a certain direction.
- The present invention also provides a new type of self-retaining retractor which is more compact and is disposable for use in open surgery. The retractor is used to hold tissues laterally, pushing tissue edges apart. For such an application, the retractor includes a U-shaped bladder which is a tube which acts like a spring and under high pressure attempts to straighten itself out when inflated. The deflated tube-like structure is first properly positioned within the wound. As the retractor is inflated, it tries to straighten out, and thus opens the wound, As it presses on the edges of the wound, it compresses tissue edges, giving a hemostatic effect. For example, if the retractor is put vertically into a wound, it expands the deep tissues. The retractor can also use the inflatable bladder to push apart metal or plastic plates to push apart tissue.

retractor 10 in accordance with the present invention. Theretractor 10 includes afluid supply structure 12 and an expandable balloon orbladder 14 located at or near the end of thestructure 12. The bladder is expandable, under the force of fluid under pressure, from an unexpanded condition as indicated in full lines at 14 to an expanded condition as shown in broken lines at 16. In the expanded condition, thetransverse dimension 18 of thebladder 14 is significantly greater than its transverse dimension before expansion, thelongitudinal dimension 20. Also, in the expanded condition, thetransverse dimension 18 of thebladder 14 is significantly greater than itslongitudinal dimension 20. - When the bladder of the retractor is expanded inside the body, it retracts tissue. As seen in FIG. 2, a
bladder 22 is mounted on the end of aseparate shaft 24 within a cannula orscope 26. The cannula orscope 26 has been inserted into the body through anopening 28 in the skin (either preexisting or made in situ) which has atransverse dimension 30. Thebladder 22 when in its unexpanded condition as shown in broken line is smaller than thedimension 30 of the body opening, but when expanded, it expands to adimension 32 which is significantly greater than thedimension 30. An actual space or workingspace 34 is formed which was not present before the expansion of the bladder. - The newly-formed working space may be used, for example, for better use of a fiber optic scope as illustrated in FIG. 3. In FIG. 3, a
retractor 10 is passed through anopening 36 in acannula 38. A fiber optic scope shown schematically at 40 is also passed through thecannula 38. Thecannula 38 is inserted into the body through an opening in thebody tissues 42 which is only as large as the outer diameter of the cannula. 38. Theretractor 10 is then inflated, with air or another fluid being supplied through a rigid orflexible shaft 44 to anexpandable bladder 46. Thebladder 46 expands transversely, retracting thetissues 42 transversely and creating a workingspace 34. By axial manipulation of theshaft 44, thebladder 46 is movable either toward the end of thescope 40 in the direction as indicated by thearrow 48, or away from the end of thescope 40 as indicated by thearrow 50, as desired. Such manipulation of the retractor can selectively move and place the adjoining body tissues where the surgeon wants them to enable better use of thescope 40 by the surgeon. - As shown in FIG. 4, the
retractor 10 may be inserted into acannula 52 through aseparate opening 54 therein. Theopening 54 is shown on the side of thecannula 52, although, of course, it may be on the end of the cannula as is typical. Alternatively, theretractor 10 may be.inserted into the body through an opening in the body tissues separate from the opening through which the fiber optic scope is inserted. Either of these options allows for greater flexibility in the insertion and positioning of theretractor 10 relative to the other instruments being used such as the arthroscope. - Also as indicated in FIG. 4, the
bladder 58 may be eccentric or eccentrically located relative to theopening 60 at the junction between thebladder 58 and theshaft 62. This is accomplished by using known techniques to form thebladder 58 of a material construction, and shape such that of it expands into the eccentric shape as illustrated in FIG. 4 when inflated by fluid under pressure through theshaft 62. In this manner, an improved visualization and workingspace 34 is created which is eccentrically located relative to the other instruments being used. This may be preferable when the surgeon is using an angled scope. - FIG. 4 is illustrative of the fact that the bladder of the retractor of the present invention may be formed so as to expand into any particular shape as desired for the particular application. This feature is also shown schematically in FIGS. 5A through 5E which illustrate, respectively, retractor bladders which assume in their expanded states in round, oval, eccentric, oblong, and conical shapes. Such shapes may generally be called “non-uniform” shapes for purposes of the present invention, and retractors with such a shape will expand in a “non-uniform” manner. Such shapes may include, for example, wedge- or U-shaped filaments that collapse at the skin, then expand at deep tissue planes for visualization and working space. The bladder may also cup and protect vital tissues such as nerves and arteries while working on other tissues such as muscle.
- Another typical form of construction is illustrated in FIG. 6, which shows a
bladder 64 that in its expanded condition assumes a toroidal shape. Again, thewidth 66 of thebladder 64 is significantly greater than its length 68. The bladder 68 is expanded by fluid under pressure received through afluid channel 70 formed between a cannula or scopeouter wall 72 andinner wall 73. By virtue of the toroidal shape of the bladder 68, the leadingend 74 of thescope 76 may be passed axially completely through the retractor into the workingspace 34 which has been created in thetissues 78. Such abladder 64 may also be mounted on a separate shaft inserted through the scope of the cannula. - In all cases, the fluid pressure within the bladder of the retractor is monitored and controlled to keep the force exerted by the retractor at a safe level for tissue to prevent tissue necrosis. As indicated schematically in FIG. 7, a
retractor 10 is supplied with fluid under pressure from afluid pressure source 80 via afluid supply line 82. Aregulator 84 controls the supply of fluid to theretractor 10. Apressure sensor 86 is located within theretractor 10 and senses the pressure of the fluid within theretractor 10. Thepressure sensor 86 sends a signal which is representative of the fluid pressure within theretractor 10, viawiring 88, to amonitor 90. Themonitor 90 is connected viacontrol wiring 92 to thepressure regulator 84. The pressure of the fluid within theretractor 10 may thus be monitored and controlled either manually or automatically, by means which are well known in the art and so need not be described further herein. Thesource 80 of fluid supply may be, for example, the air pressure supply which is commonly found in hospital operating rooms. - By virtue of this ability to monitor the pressure within the
retractor 10, theretractor 10 can also be a useful diagnostic tool. The strength or pressure or resistance of tissue to movement can be measured by the pressure required to move it. - FIGS. 8 and 8A illustrate the use of a retractor of the present invention to stabilize a fiber optic scope. The retractor10 (FIG. 8) includes a
bladder 94 which retracts thebody tissues 96 away from thescope 98. Since thebladder 94 engages and pushes radially outwardly onbody tissues 96 all around thescope 98, the retractor becomes fixed in position when it is so expanded. If thebladder 94 is fixed to the end of thescope 98, theretractor 10 thereby fixes the end of thescope 98 in position relative to thebody tissues 96. When a camera is being used with thescope 98, the picture normally moves or jumps around because of the movability of the end of thescope 98. This is prevented by so using theretractor 10 to stabilize thescope 98, leaving the surgeon with both hands free to work and a steady view of the work area. - FIGS. 8 and 8A also illustrate how the retractor of the present invention can be used to control the placement of the tip of a fiber optic scope. The
retractor 10 is formed with aneccentric bladder 94 which retracts thebody tissues 96 away from thescope 98 to a greater distance in one direction than in another. Thus, by rotating theretractor 10, the surgeon can place the tip of thescope 96 closer to the body tissue 100 (FIG. 8) on one side of the workingspace 34, or to the body tissue 102 (FIG. 8A) on the other side of the workingspace 34. Such variable placement can, of course, also be attained via use of aretractor 10 that includes a bladder that can be expanded to varying shapes. - The retractor of the present invention has many uses in the surgical field. FIG. 9 illustrates the use of a
retractor 10 to retract soft tissue from bone, for example within a joint. Theretractor 10 is inserted between the bone 110 and the soft tissue 112. Thebladder 104 is then expanded. The soft tissue 106 is forced away from thebone 104. The surgeon may then use a fiber optic scope or other instrument to work within the workingspace 34 created by theretractor 10. The retractor of the present invention can provide the force needed to move the soft tissue 112 away from the bone 110 may vary between about 100 and 1000 mm Hg, and thus, it is important to maintain the proper pressure between the two. Theretractor 10 can do this since it operates on high fluid pressures of about 10 to 1000 mm Hg and it utilizes a high strength material such as Kevlar, Mylar, or another durable polymer such as Polylite®, a product of Reichhold Chemicals, Inc. This simple retraction of soft tissue from bone would otherwise be impossible. - FIG. 10 illustrates the use of a
retractor 10 to enable a surgeon to work within a shoulder joint. The joint includes thehumeral head 114, the glenoid 116, theacromium 118, and the acromium joint 120. Therotator cuff 122 is attached to thehumeral head 114. Ascope 124 is inserted preferably from the back of the shoulder joint. In the prior art method, theacromium 118 can be separated from the bone from within the joint, in order to gain access to the rotator cuff, only by introducing an unconfined stream of water into the joint as indicated at 126. This method leads to the presence of water everywhere, including within the tissues themselves, and is not a desirable method. In accordance with the present invention, aretractor 10 with an expandable bladder is simply inserted through a small incision in the skin and inflated to expand in the direction indicated by thearrow 130, thus retracting the tissue space. There is no unconfined fluid introduced into the tissue space, and the degree of separation of the joint is easily and safely controlled by controlling the pressure within theretractor 10. - FIGS. 11, 11A,12, and 12A illustrate the use of a
retractor 10 to enable a surgeon to better work within a knee joint. The joint includesfemur 132 andtibia 134 and between them aneurovascular bundle 136 which the surgeon wishes to work on (or work around). However, thenormal space 138 within the tissue space is so small as to make working within the joint very difficult or impossible. Accordingly, a retractor that is in the form of a wedge-shaped bladder 140 (FIGS. 11 and 11A) is inserted on one or both sides of the knee joint and expanded. The retractor expands in a straight or curved shape depending on its dimensions and easily separates the joint, creating a much enlarged working space 142 (FIG. 11A), enabling the surgeon to operate via any instrument such as the scope illustrated schematically at 144. In a similar manner, a surgeon can easily spread adjacent vertebrae in a spine to work on the spinal column, for example to remove a spinal disc or any other tissue or bone. Thebladder 140 may also be formed with a curved shape or otherwise custom-fit for the particular application. - The
retractor 10 shown in FIGS. 12 and 12A operates similarly, with the exception that thebladder 146 is formed as a bellows-type device which expands in an accordion-like manner. The material of which the bellows-type bladder 146 is made does not necessarily stretch although it may somewhat, but rather the expansion comes primarily when the various surfaces are repositioned relative to each other. The accordion-like ridges 148 may be made of differing degrees of resistance to straightening and flexing, in order to vary the rate and/or sequence of inflation of various portions of thebladder 146. Alternatively, the material of which thebladder 146 is made has areas of rigidity interleaved with areas of more elasticity, to provide the desired expansion effect. Theridges 140 may also be closure members that divide thebladder 146 into a plurality of separate inflatable chambers with valving therebetween, for sequential inflation. Such an accordion-like or bellows construction can provide greater stability in intermediate (partially expanded) positions, and can have greater structural integrity. - FIG. 13 illustrates how a pair of retractors in accordance with the present invention can be used together to create a working space between them. In the operation illustrated schematically in FIG. 13, the surgeon desires to retract a fat pocket or
tissue 150 away from aknee 152 in order to provide a workingspace 34 between them in which he can operate. Acannula 154 is inserted through asmall opening 156 in theskin 158 and through the fat pocket ortissue 150. Aninner bladder 160 is inflated inside the fat pocket ortissue 150, while anouter bladder 164 is inflated on the outside of theskin 158. Drawing the two bladders toward each other pulls the fat pocket ortissue 150 toward the skin and away from theknee 152, thus creating the enlarged workingspace 34. This enables the surgeon to operate comfortably with a scope orother instrument 166, while still performing the entire operation percutaneously as is, of course, desired, meanwhile stabilizing the instrument. - In a somewhat similar manner, two separate retractors can be used to create a working space in between the two retractors. For example, FIG. 14 illustrates the use of a pair of retractots to create and maintain an open working space in a
duodenum 170. Afirst retractor 172 is inserted through thestomach 174 on a scope orcannula 176 and is inflated at the upper end of the duodenum 170 to block it off from thestomach 174. Asecond retractor 178 is inserted through thestomach 174 on the scope orcannula 176 and is inflated lower on theduodenum 170 to block it off from the small intestine. An open workingspace 34 is thus created between theretractors retractors growth 180 in theduodenum 170. The retractor may also be used to block off an artery in a bleeding area of the bowel by direct pressure. - Similarly, FIG. 15 illustrates the use of a pair of retractors in accordance with the present invention to create a working space in a blood vessel. A
first retractor 182 is inserted through amain blood vessel 184 on a cannula 186 and is inflated to block thevessel 184 from blood flow in one direction. A second retractor 108 is inserted through thevessel 184 on aseparate shaft 190 through the cannula 186 and is inflated farther along thevessel 184 to block blood flow from abranch blood vessel 192. An open workingspace 34, free of blood, is thus created and is maintained as long as bothretractors scope 194 within themain vessel 184. - As noted above, an important advantage of the retractor of the present invention is that it can be used percutaneously to create a large actual space within the body while making only a small opening in the skin. This allows for percutaneous or fiber optic surgery in locations where heretofore only open surgery with its attendant disadvantages was possible. This feature is illustrated in FIG. 16 which shows in solid lines a
retractor 10 for insertion through acannula 196 into anopening 198 inskin 200. Theretractor 10 is, at the time of insertion, no larger in diameter than theopening 198. However, once inserted into location subcutaneously, theretractor 10 can be expanded to the condition shown in broken lines to create a working space which as illustrated by the relative size of the arrow 202 is significantly larger than theopening 198 in theskin 200. - The retractor illustrated in FIGS.17-17C uses a bladder that is longer than it is wide but which is hollow. To gain access to the
surface 204 of abone 206, asmall opening 208 is formed extending through theskin 210 and themuscle 212. Theopening 208 extends down to thesurface 204 of thebone 206. A retractor 214 (FIG. 17A) is then inserted, in an unexpanded condition, into theopening 208 and down into contact with the surface of the bone. The retractor has aninner wall 215 and anouter wall 217 with afluid space 219 between. Theretractor 214 is then inflated, as seen in FIG. 17B, retracting the adjoiningskin 210 andmuscle 212 radially outwardly. Theretractor 214 has a hollow cylindrical shape with anopening 216 in the middle (see FIG. 17C). Theopening 216 is significantly larger than theopening 208. A surgical or other instrument can be inserted through the opening 216 from outside the body, into contact with thesurface 204 of thebone 206, while theopening 216 is being maintained. Thus, a large opening can be temporarily created with only a small opening in the body tissue. - In a variation on the: retractor shown in FIGS. 17C, a retractor like the
retractor 214 is shorter and has a. ring shape when expanded. The retractor is slid into the body tissue over a small pin such as a K-wire which has been used to pinpoint the desired area. The retractor is slid in while deflated, then expanded when at the desired location inside the body. The inner diameter when expanded, though slightly less than the outer diameter, is still much larger than the size of the pin, forming a large working and visualization space for the surgeon. The surface of the retractor may be roughened, ribbed, or serrated for better gripping power to keep the retractor in place while expanded. - In another embodiment of the invention illustrated in FIGS.18-18D, the one-piece bladder of the
retractor 10 is replaced by a series of plates or filaments that are expanded radially or conically outwardly to retract the adjoining tissue. These plates or filaments may, as illustrated in FIGS. 18 and 18a, be rigid orsemi-rigid elements 218 which are expanded radially outwardly by a centrally locatedpositioner 220 which may be mechanical or which may be air-operated such as an expandable bag. This is in the nature of a spring loaded umbrella with a sleeve which slides over the ribs of the umbrella, which ribs open and expand outwardly when the sleeve is pulled back. Alternatively, as illustrated in FIGS. 18B and 18C, thefilaments 222 are hollow inflatable elements which themselves inflate upon application of fluid under pressure to theretractor 10, straightening out as they fill with pressurized fluid. In either case, asleeve 224 is preferably provided to protect and help locate or position the radially movable elements. Thesleeve 224 slides axially. The plates or filaments are covered bysheath 224, which slides off them proximally axially to allow them to be expanded radially outwardly to push tissue away from the scope to improve visualization. After deflation, thesleeve 224 slides distally along the shaft over the filaments to cover them and allow theretractor 10 to be moved through the body. A sleeve such as thesheath 224 can also be employed in conjunction with a unitary bladder. In either event, the sleeve can be rigid or can be flexible. - Retractors in accordance with the present invention can also be used for open surgery. FIGS.19-19C are a series of schematic views illustrating the use of a retractor of the present invention in open surgery. The retractor is used to hold tissues laterally, pushing tissue edges apart. FIG. 19 shows the
edges opening 230. As seen in FIG. 19A, anopen surgery retractor 232 has been inserted down into theincision 230. Theretractor 232 is in the form of a hollow expandable tube that is bent into a V-shape or a U-shape for insertion into theincision 230. It may have a lip or ridge on the surface engaging the tissue to better hold it in place. The deflated tube-like structure is first properly positioned within thewound 230. Upon inflation, the tube under fluid pressure attempts to straighten itself out, and thus opens the wound 230 (FIG. 19B) for easier access by the surgeon. As theretractor 232 presses on theedges legs - As seen in FIG. 20A, a plurality of separately inflatable radially spaced
bladders rod 254. Thebladders - Alternatively, as seen in FIG. 20B a plurality of separately inflatable axially spaced
bladders rod 244. The,bladders tube 260 having a.plurality ofbladders 262A through 262F that are deflated. When it is desired to selectively rigidify a portion of thetube 260, thebladders 262C through 262F are inflated (FIG. 20D), providing support for the tube at their corresponding axial locations and rigidifying the corresponding portion of thetube 260 as desired. - When a plurality of separately inflatable bladders are located on the same supporting device, suitable apparatus is provided for their inflation. Such apparatus may be, when only a few bladders are present, a simple mechanical valving apparatus. When more bladders are present, or more sophisticated or complex control thereof is desired, a microprocessor may be used to control the inflation. In such case, the control signals may be multiplexed down the structure via optical fiber or wire, for example.
- As further illustration of the variety of shapes of retractors which can be used, FIGS. 21 and 21A illustrate the provision of pie-shaped retractors which create a working space between the edges of the pie. The supporting structure carries a pie-shaped
retractor 272 which, when inflated as shown, provides aspace 274 for visualization and working. If twosuch retractors 272 are spaced axially as seen in FIG. 21A, an extended working andvisualization area 272 is provided for the surgeon. - In the embodiment shown in FIG. 22, a
bladder 280 is split at twolocations lobes - A surface of the retractor may be reflective, to allow the surgeon to see within the opening created by the retractor at different angles rather than merely straight in. The retractor292 (FIG. 23) has a reflective surface or
mirror 294 which enables visualization at an angle a which may be varied through inflation of thebladder 292 by various amounts. This is an especially appropriate use for the bellows type construction of the bladder as described above, wherein the surface of the bladder has a plurality ofridges 296. The retractor may thus be used to reflect light or a laser beam for visualization with a camera. - Another suitable use for the retractors of the present invention is in carpal tunnel surgery that can be otherwise quite difficult. The retractors are used to cup, move, and protect the nerves during the operation. FIG. 24 illustrates schematically a sectional view through a
wrist 300 and showing theradius 302,ulna 304,median nerve 306, andtendons retractor 312 is inflatable radially outwardly in the directions indicated by thearrows 314, to push thetendons 310 in the direction indicated by the arrow 316 and away from themedian nerve 306. Thus, space is created adjacent the tendons and median nerve, at a location axially from theretractor 312, for visualization and working. Asecond retractor 318 may be simultaneously used to create a longer working andvisualization space 320, as seen in FIG. 24A. - From the foregoing description of preferred embodiments of the invention, those skilled in the art will perceive improvements, changes and modifications in the invention. Such improvements, changes and modifications within the skill of the art are intended to be covered by the appended claims.
