Description
APPARATUS AND METHOD FOR PROTECTING A PORT SITE OPENING IN
THE WALL OF A BODY CAVITY
Background of the Invention
The present invention generally relates to an apparatus and method for protecting a port site opening in the wall of a body cavity. The present invention particularly relates to an apparatus and method for protecting a port site opening in the wall of a body cavity which is used with a trocar assembly.
Minimally invasive surgical techniques, such as laparoscopic surgery, typically include a trocar to create a small hole or port in a wall of a body cavity so as to gain access to the body cavity. Surgery performed by using these techniques is generally associated with lower postoperative morbidity, shorter postoperative stay, less postoperative pain, decreased cost, and quicker recovery as compared to "open" or conventional surgical techniques. Because of the aforementioned advantages, these minimally invasive techniques are being applied to an increasing variety of all surgical procedures. For example, laparoscopic procedures for the resection of malignancies have emerged. In particular, laparoscopic colectomy for carcinoma of the colon has been developed, and it has been reported that the initial results of these procedures have advantages over operations performed in the traditional open manner. Moreover, it is hoped that the long term results of these procedures will be comparable, or better than, those performed in the traditional open manner.
However, the field of laparoscopic surgery for cancer has been delayed in its development because of the major concern regarding the implantation of tumor cells in the port site wound. Minimally invasive surgical techniques for treating cancer require the removal of a malignant neoplasm through the small
incision or port site created by a trocar These procedures require the dragging of tumor tissue through the port site which creates a risk of implanting tumor cells in the walls of the wound forming the extraction site An additional concern is that tumor cells exfoliated during the procedure will come into contact with, and contaminate, the port site wound This contamination can occur as a result of the exfoliated tumor cells being in fluid communication with the port site wound Regardless of how these cells contaminate the wound, once implanted therein, viable tumor cells can cause a subcutaneous metastases or "port/extraction site recurrence" after the resection of malignant tissue In fact, numerous port site recurrences have been documented in the medical literature heretofore and subcutaneous metastases after laparoscopic resection of malignant tissue has been described as a potentially serious complication of laparoscopic cancer surgery These "port/extraction site recurrences" have delayed the advancement of laparoscopic cancer surgery Furthermore, laparoscopic surgery performed for general surgery, gynecological surgery, urological surgery, or any other mtra-abdominal infection is associated with a small but real incidence of port site wound infection The infecting bacteria causing these illnesses can contaminate the port site wound by the same mechanism as discussed above with reference to tumor cell contamination and these infections can increase a patients morbidity and consequently the length of a patient's hospital stay, thereby considerably increasing their hospital bill
Therefore in light of the above discussion, it is apparent that an apparatus for preventing port site tumor implantation and reducing the incidence of port site infection, is desirable The present invention provides such an apparatus in the
form of a protective trocar sleeve One advantage the present invention has over the prior art is that it can be retrofit to existing trocar assembly technology Moreover, once attached, the described invention adds only a minimal amount of bulk to the diameter of the trocar assembly In use, the present invention protects the port site from infection or tumor cell implantation thereby lowering the morbidity and mortality of a wide variety of minimally invasive surgical techniques The present invention allows the field of laparoscopic surgery to be safely applied to all forms of cancer surgery while minimizing "port site recurrences " The present invention also allows the field of laparoscopic surgery to be safely applied to all forms of laparoscopy while minimizing port site infections

Detailed Description of the Preferred Embodiment
While the invention is susceptible to various modifications and alternative forms, a specific embodiment thereof has been shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. Referring to FIGS. 1 , 4 and 5 there is shown a medical apparatus 10 of the present invention advanced through an opening 26 in a wall 28 of a body cavity 34. The medical apparatus 10 includes a sleeve 18 having a passageway 24 extending therethrough. The sleeve 18 includes a number of sealing members 20. The medical apparatus further includes an actuator 38 and a trocar assembly 12. The actuator 38 includes a guide member 40 and handles 42. The sealing members 20 extend from a distal end 22 of sleeve 18. The trocar assembly 12 includes a cannula 14 and a trocar 16 positioned within passageway 24 of the sleeve 18.
As illustrated in FIG. 2, cannula 14, sealing members 20, and guide member 40 are all respectively nested within each other in a substantially concentric relationship (a portion of handles 42 is also shown extending above guide member 40). Cannula 14 is slidably fit into passageway 24 of sleeve 18 so as to allow its movement relative to sleeve 18. It should also be understood that cannula 14 and sleeve 18 are fit in such a way as to form a substantially gas tight junction so that substantially no gas leakage occurs through this junction during
insufflation of the body cavity 34 The aforementioned gas tight junction may be formed using rubber gaskets or o-πngs
Guide member 40 is slidably mounted onto sleeve 18 so it can be moved between a first position as shown in FIG 4 and a second position as shown in FIG 5 The double headed arrow 93 of FIG 1 shows the direction of movement of guide member 40 Specifically, FIGS 1 - 4 show guide member 40 placed in the first position, whereas FIGS 5 and 7 show guide member 40 placed in the second position As illustrated in FIGS 1 , 3, 5 and 7, the position of guide member 40 controls the movement of sealing members 20 between a first orientation and a second orientation The sealing members 20 are positioned in the first orientation when the sealing members 20 are positioned in a substantially parallel relationship with passageway 24 of sleeve 18, as shown in FIGS 1 -4 The sealing members 20 are positioned in the second orientation when the sealing members 20 are positioned in a substantially orthogonal relationship with passageway 24 of sleeve 18 as shown in FIGS 5 - 7
Moreover, as depicted in FIG 6 when sealing members 20 are in the second orientation they extend from the distal end 22 of sleeve 18 (not shown in FIG 6) so as to overlap one another, thereby completely surrounding passageway 24 of sleeve 18. FIG 6 shows sealing members 20 extending to form an annular flange
However, it should be appreciated that the present invention is not limited to the geometric shape formed by the extending sealing members For example, other geometric shapes are contemplated, such as square or oval shaped configurations Moreover, a single sealing member extending from a distal end of a sleeve, or a number of non-overlapping sealing members spaced around a
distal end of a sleeve are also contemplated Furthermore, sealing members having perforations thereon which can be torn and separated prior to positioning in contact with the interior surface of a body cavity wall are also contemplated Sleeve 18 and guide member 40 can be made from any plastic material which is conventionally used in the medical device arts Such material would be compatible with insertion into a body cavity It should also be noted that the guide member used in the present invention can be manufactured to a size which only adds a minimal amount of bulk to the diameter of a trocar assembly By doing so trauma to the body cavity wall upon insertion of the medical apparatus of the present invention will be reduced
Sleeve 18 and sealing members 20 are formed such that when no force is applied to sealing members 20 they spontaneously assume their second orientation (see FIGS 5 - 7) Moreover, sealing members 20 are flexibly attached to distal end 22 such that when force is applied (i e the force applied by sliding guide member 40 over the sealing members 20) the sealing members 20 assume their first orientation (see FIGS 1 - 4)
Handles 42 can be made of any material having the appropriate beam strength to move guide member 40 from the first position to the second position When performing a medical procedure with medical apparatus 10, such as a laparoscopic surgery, guide member 40 is placed into the first position (see FIGS 1 - 4) so that sealing members are maintained in their first orientation (see FIGS 1 - 4) Trocar 16 of medical apparatus 10 then contacts with and is advanced through wall 28 of a body cavity 34 to create an opening 26 Preferably, sleeve 18 and trocar 16 are simultaneously advanced through the opening 26 and into body cavity 34 It should be appreciated that maintaining
sealing members 20 in their first orientation facilitates the advancement of sleeve 18 through opening 26 and into body cavity 34.
Once distal end 22 of medical apparatus 10 enters into body cavity 34 through opening 26, handles 42 are moved away from opening 26 in the direction of arrow 94 (see FIG. 1 ) so as to slide guide member 40 to the second position (see FIGS. 5 and 7), thereby allowing sealing members 20 to assume their second orientation. Once sealing members 20 have assumed their second orientation they are positioned to contact the interior surface 56 of the body cavity wall 28 so as to prevent fluid communication between an area inside of the body cavity and an area outside of the body cavity through the space 36 defined between the opening 26 and the sleeve 18.
It should be understood that a ridge (not shown) or a number of "flange teeth" (not shown) extending from the surface of the sealing members and contacting the interior surface of the body cavity wall is also contemplated. Such a ridge or "flange teeth" will also contact the interior surface of the body cavity wall and assist in preventing fluid communication between the area inside of the body cavity and the area outside of the body cavity through the space defined between the opening and the sleeve. The aforementioned ridge or "flange teeth" will also keep the sealing members stationary relative to the interior surface of the body cavity during manipulations of the cannula.
Once the medical procedure is completed, handles 42 are moved toward opening 26 in a direction opposite to arrow 94 so as to slide guide member 40 to the first position (see FIGS. 1 - 4). The movement of guide member 40 to the first position forces sealing members 20 to assume their first orientation (see
FIGS 1 - 4), thereby facilitating the removal of medical apparatus 10 from
opening 26
Now referring to FIG 8, there is shown a medical apparatus 62 similar to the medical apparatus 10 shown in FIG 1 Medical apparatus 62 is shown advanced through an opening 70 in a wall 66 of a body cavity 74 The medical apparatus 62 includes a sleeve 82 having a plurality of perforations 46 defined in its proximal end portion and an adhesive material disposed on its outer surface 91 The sleeve 82 includes a number of sealing members 64 positioned in a second orientation extending from distal end 78 The medical apparatus 62 further includes a guide member 72 positioned in the second position Medical apparatus 62 also includes a stnppable liner 84, surrounding and in contact with, the adhesive material disposed on outer surface 91 The stnppable liner has perforations 86 formed thereon
Medical apparatus 62 is used in the same manner as described above with reference to medical device 10 However once the sealing members are positioned in contact with an interior surface 68 of body cavity wall 66, stnppable liner 84 is torn along perforations 86 to expose the adhesive material disposed on the outer surface 91 of sleeve 82 As shown in FIG 9, sleeve 82 is then torn along perforations 46 down to guide member 72 to form a number of elongated strips 88 having a first surface 95 with the adhesive disposed thereon It is also contemplated that sleeve 82 may be formed from a material having the physical property of molecular orientation whereby a tear in the material runs readily only in a longitudinal direction along the length of sleeve 82 A sleeve formed from such a material will eliminate the need for the above described perforations
Once the elongated strips 88 are formed, a first surface 95 of each strip 88 is attached to an exterior surface 90 of body cavity wall 66 with the adhesive.
An important aspect of using elongated strips 88 in the above described manner is that they cooperate with sealing members 64 to stabilize the position of medical apparatus 62 in opening 70. The attachment of elongated strips 88 to the exterior surface 90 of body cavity wall 66 also keeps sealing members 64 in contact with interior surface 68. This ensures that no fluid communication exists between an area inside of the body cavity 74 and an area outside the body cavity through the space 97 defined between the opening 70 and the sleeve 82. Based upon the above description it will be understood by those skilled in the art that the present invention provides a medical apparatus for protecting a port site wound which adds only a minimal amount of bulk to the diameter of a trocar assembly. Moreover, it will be understood by those skilled in the art that the medical apparatus of the present invention can be retrofit to existing trocar assembly technology. Furthermore, the medical apparatus of the present invention allows minimally invasive surgical techniques, such as laparoscopic surgery, to be safely applied to cancer surgery.
While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description is to be considered as exemplary and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected. For example, while the mechanism described above for moving the sealing members from the first orientation to the second orientation has many benefits, other mechanisms may be used. One such mechanism may utilize
pressure in the body cavity to force the sealing members against the interior surface thereof.
