Abstract

A single body port or body flange access device and method for performing laparoscopic surgery are disclosed. The device comprises a plurality of crisscrossing conduits through which surgical instruments may be inserted. The instruments are manipulated so that triangulation is obtained using one patient body flange while standard surgical procedures are performed on the patient.

Description

APPARATUS AND METHOD FOR MINIMALLY INVASIVE SURGERY
Technical Field of the Invention This device and method relate to laparoscopic surgical procedures and in particular to an improved device and method for minimally invasive surgical procedures.
Background of the Invention
Minimally invasive surgery has improved patient care by decreasing pain, shortening hospital stays, offering a faster recovery time and much smaller scars. In fact the surgical procedure is much shorter than standard procedures and offers less chance of infection, etc. These laparoscopic procedures are proving popular with the patient. During minimally invasive procedures for the abdominal surgeries such as: laparoscopic appendectomy (removal of the appendix); laparoscopic cholecystectomy (removal of the gallbladder); laparoscopic colectomy (removal of part or all of the colon); laparoscopic fundoplication (corrects severe or persistent acid reflux); laparoscopic hysterectomy (removal of the uterus); or laparoscopic ventral hernia repair (repair of an abnormal bulging of the abdominal wall often at the site of a previous surgical incision), the surgeon makes a series of three to five small, dime-sized incisions in the patient's abdomen. Carbon dioxide gas is used to inflate the abdomen and create a working space between the internal organs and the skin. A small video camera, or scope, then is placed in one of the incisions, providing the surgeon with a magnified view of the patient's internal organs on a television monitor in the operating room. In some procedures, like MIP for colon conditions, a slightly larger incision may be needed.
Thus, the procedure requires body access devices, which are utilized to introduce visualization equipment and operative instruments rather than a standard incision to access a required part of the body. Nonparallel instrumentation is necessary to create a "depth of field" (3 -dimensional vision) and introduce a variety of instrumentation. This concept is commonly known as triangulation.
In the past multichannel devices have been used by the surgeon using narrow parallel channels (within the single multichannel access device). These narrow parallel channels have been found to limit the field of view and reduce depth perception. Thus, multichannel devices have not met the needs of the surgical community and are rarely used. Nonparallel multiple access devices would allow the surgeon to introduce numerous types of instruments with triangulation through one body access opening. This concept would preserve triangulation and create the required field and depth of view while allowing the surgeon to utilize one body flange for multiple simultaneous tasks, which would be required to complete an operation on any applicable body area or space. The current state of the art utilizes entry devices (body flanges) that have a similar cross-section as a silver dollar and incorporate a control head (gas in fusion port and sealing systems for insertable surgical instruments that have almost double cross-section as the part of the flange that attaches to the abdominal wall or body entry port. This means that large incisions will be used when operating on obese patients to allow for the large control head.
WiIk in U.S. Patent 5,183,471 discloses a "Laparoscopic Cannula" that has a central conduit with a side crossing conduit that passes through the central conduit thereby creating an obstacle within the central conduit. The disclosure teaches a means to facilitate the temporary insertion of an extra laparoscopic instrument without having to make another perforation of the abdomen. The side crossing conduit will require that the central conduit be large; otherwise, a standard instrument would not be able to pass through the central conduit. The central conduit will allow a surgical instrument to "look" vertically downward over the operation point while the side crossing conduit will pass an instrument to one side of the operation point. WiIk continues to teach a second body flange for illumination and vision and does not discuss triangulation.
WiIk in U.S. Patent 5,269,772 discloses a "Laparoscopic Cannula Assembly and Associated Method" which essentially is two parallel swiveling conduit passing through the same body opening and is a continuation-in-part of his '471 disclosure examined above. The parallel conduits do not cross over each other; however, the device will allow one instrument to be to one side of the operation point while the other instrument may be to the other side. The swiveling assembly will require a rather large opening in the abdomen wall. As in his '471 disclosure, he continues to teach a second body flange for illumination and vision and does not discuss triangulation.
Yoon in U.S. Patent 6,066,090 discloses a "Branched Endoscope System" which discusses a single body flange having a plurality of tubes passing through the conduit for various surgical instruments. Yoon shows an embodiment in which the inside section of the body flange splits in two parts each having a bend thereby allowing a tube to overlook the other tube. The Yoon '090 device is designed to pass through the current art body flange having a single conduit.
Yoon in U.S. Patent 6,277,064 discloses a "Surgical Instrument with Rotatably Mounted Offset Endoscope." The apparatus is a variation of the '090 device and is designed to pass through the current art body flange having a single conduit.
Wenner et al. in U.S. Patent 6,440,061 disclose a "Laparoscopic Instrument System for Real-Time Biliary Exploration and Stone Removal." This device has multiple ports within its system, but, like Yoon, is designed to pass through the current art body flange having a single conduit. Bimbo et al. in U.S. Patent 6,551 ,270 disclose a "Dual Lumen Access Port." The device is essentially a current state of the art body flange with parallel entry ports that open into a single conduit which will accept two surgical tools through one body flange without ensuring a three dimensional field of view. Bimbo teaches multiple instruments through a single conduit but does not explore the concept of a single body flange replacing surgical procedures using multiple body flanges.
Thus, what is needed in the art is an apparatus and method that would allow the surgeon to perform minimally invasive operations with body flanges having a smaller overall cross-section while allowing for triangulation within the patient. Such a device and method will result in with fewer incisions for body access openings thus further decreasing the pain caused by surgery and further decreasing the recovery time and further reducing the risk of infection. Summary of the Invention
The invention consists of a "body flange" or "trans-axis-uniport" ("TAU") which is anchored to the body with a standard suture anchoring points. In turn, the body anchor contains a crisscrossed plurality of conduits which allow nonparallel introduction of equipment and/or instruments. The conduits may be parallel, nonparallel, straight or curved, but enter the body through one body opening. (It may be necessary during some procedures to have additional body openings.)

Description of the Preferred Embodiment
In reading this disclosure, the reader should understand that the term body flange generally means the entire device used to temporarily seal an incision in a patient. Thus, the body flange would include the body anchor — the section of the device that fits within the abdominal wall and is temporality sutured to the abdominal lining, any passageways extending through the body anchor (both above and below), any seals or other apparatus that is required to form the complete temporary entry closure.
Refer now to Figure 6 which shows an oblique view of the body anchor, 1, of the instant invention. The invention comprises of two crisscrossed (non-parallel) apertures, 2 and 3, passing through the body anchor. Figure 14 shows an alternate embodiment in which two parallel apertures, 5 and 6, pass through the body anchor, 1. Not shown are the standard suture anchor points or tiedowns on the anchor.
Figure 7 shows the complete body flange utilizing the straight instrument conduit, 11 and 12, embodiment. Not shown are required seals within the conduits, which are similar to the current art and serve to retain the body inflation gas while various instruments are inserted and withdrawn through the body flange during the operation. Such a representative seal is shown in Figure 4 of U.S. patent 6,551,270, which is incorporated by reference. Similarly the standard inflation gas port(s) is not shown. A representative gas port is shown in Figure 1 of U.S. Patent 6,440,061 which is incorporated by reference. The '061 patent also discusses gas seals.
Figure 8 shows an alternate embodiment of the instant invention utilizing one straight conduit, 13, and a curved or bent conduit, 14. Figure 9 shows a further embodiment of the instant invention utilizing two curved conduits, 15 and 16.
Figures 3 and 4 and Figures 6 through 14 and Figure 16, detail the crisscrossed nature of the longitudinal axis of each conduit passing through crisscrossed apertures within the body flange. This is the preferred invention because the preferred mode allows for ready triangulation of instrumentation (as explained below). It is possible to obtain triangulation with parallel apertures as shown in Figure 15 and thus parallel apertures (with guiding conduit) are considered within the scope of the instant invention, Figures 13 and 14 show cross-sectional views through the body of the instant device used in the illustration of Figures 3 and 4. Figure 13 shows the embodiment of Figures 7 and 12 (both conduit being straight) used in a normal person. A single suture is shown running through the abdominal lining and passed back up to the notch, 22: this suture holds the body flange, 1, in place during the operation. The second required suture is not shown (for clarity) but will also terminate in the notch. The technique is similar to the current state of the art. (It is possible to manufacture a system having a second notch — not shown - on the other conduit.)
Figure 10 shows an alternate suture "tie post" or tie-off, 21, based on the prior art. Because the body anchor is so small only one post is required, but the suture requires a guide, 26, to stop the two sutures from sliding around the circumference of the plug.
Figure 14 shows the noticeable advantage of the instant device when used in obese persons. Figure 14 shows the embodiment of Figure 9 in which both conduits are curved. The crisscross occurs within the body flange itself, but because the curved conduits, 15 and 16, pass over and beside each other on the outside (of the flange) the resulting cross- section remains the same as the cross-section of the body flange or at worst only slightly larger. Thus, the incision size is substantially reduced over the current art. Again, a suture is run through the abdominal lining and passed back up to the notch, 24: this suture holds the body flange, 1, in place during the operation. (Only one of two sutures is shown for clarity.) Note that an anchor using the suture post of Figure 10 may be substituted for the notches, 23 and 24.
Figure 16 shows the instant device in use with surgical instruments. The straight instrument, 36, represents a standard instrument and the bent instrument, 35, simulates a flex scope with a bend. The bend serves only to illustrate how the surgical instruments function together: while still being independent. For simplicity the term instrument is used to designate the actual medical (surgical) instrument that is passing through the conduits of the body flange of the instant invention. The term flex-scope is the standard adjustable video scope used in surgical procedures. Figure 16 shows suture notches, 22 and 24. This is for the purposes of illustration only as only one such notch is required; furthermore the tie post, 21, and guides, 26 of Figure 10 may be substituted.
The size of the flex-scope can vary and is set by the number of instrument channels within the flex-scope. The important and key instrument is the bendable flex-scope shown in the figure cross coupled with a standard instrument (or flexible instrument) so that a three dimensional view is obtained and maintained during the procedure. The "bendable" channel houses the optics used in the laparoscopic procedure (camera and illumination). Note that due to the bendable channel the optics will provide a field of view that approaches that of a three dimensional view of the surgical area.
Figure 17A is a further embodiment of the body anchor showing the crisscrossed apertures along with a third aperture, 4, that will place a surgical instrument midway inline with the instruments using the other apertures, 2 and 3.
Figure 17B is similar to Figure 17A; however, the drawing shows one the crisscrossing apertures, 3, as being curved. The curved aspect of the aperture is probably the best manner to actually build crisscrossing apertures within the anchor and the curve will serve to better guide instruments through the enclosed conduit (the conduit that passes through the crisscrossing apertures). Figure 17B really serves to illustrate the best mode to make the crisscrossing apertures; although, the actual shape (curved or straight) will be set by the style of instrument to pass through the conduit/aperture pair.
Although not shown, it is possible to incorporate a rotable seal within the apertures of the body anchor which would allow the conduit to rotate with respect the anchor and to themselves. This would then aid in vectoring surgical instruments for triangulation.
Figures 1 and 2 show the current art using a plurality of canula or instruments. Port 1 (Pl in figures 1 and 2) is equivalent to the single port (Pl) in figures 3 and 4. The crisscrossed conduits (TAU) of the instant invention serve the same function as ports 2 and 3 (P2 and P3) in Figures 1 and 2 — the prior art. One of the conduits serves to allow the optics to enter the surgical area while the other conduit serves to allow for additional instruments. Note how the field of view gives a three dimensional effect (so that distance can be judged by the surgeon) is obtained with the single port using the instant invention as compared to three (or more) ports of the prior art.
Figures 3 and 4 show clearly how the flexible channel (flex-scope) serves the same function as the canula of ports 2 and 3. Some surgical procedures only need two ports (for example Pl and P2) thus; Figure 16 shows a direct replacement for this procedure. On the other hand, most procedures required three points of access as shown in Figures 1 and 2 (for example Pl5 P2 and P3) thus; Figure 16 shows a direct replacement for this procedure. The bendable flex-scope holds the optics and provides one or more additional channels for instruments. It should be noted that the second instrument may also be bendable. It should be noted that Figures 1 through 4 imply a laparoscopic appendix operation. Referring now to Figure 4 and single port Pl, if something goes wrong during the laparoscopic procedure (e.g. a burst appendix) and the normal procedure has to be performed, port Pl need only be extended for the surgeon the "fall-back" to the standard appendectomy.
To use the device, the surgeon would carefully choose the position of the single port opening. The choice is relatively simply. The single port opening must allow for proper cross-over of the instruments so that a three-dimensional view of the surgical area of interest is obtained. The surgeon makes the incision using standard techniques inserts the instant device, sutures the device in place and runs ihe flex-scope and required instruments through the appropriate conduit in the device. Standard and proven techniques are then used to perform the surgery. Closing is standard.
Figures 18 A and 18B show how surgical instruments when passed through the conduit which are crisscrossed within the body anchor will automatically align along a straight line within the body. This means that the surgeon, as the instruments are inserted, mentally knows how the instruments are aligned and the triangulation required for depth perception is guaranteed. Figures 19A, 19B, 2OA, and 2OB show how the required guaranteed triangulation cannot be obtained. Thus a single body flange, which can be extremely small compared with the current art, can be used to guarantee the required triangulation for depth perception.
What has been disclosed is an apparatus and method for an improvement to minimally invasive (laparoscopic) surgery. The technique shown uses one body flange in a single body opening; however, a second body opening is not outside the scope of the method and apparatus. The preferred mode using crisscrossed conduits has been described; however, parallel conduits and even a combination of crisscrossed and parallel conduits are envisioned. The conduits themselves which pass through the apertures of the body plug guarantee triangulation for depth perception within the body flange.
