Apparatus for retracting an incision and inflating an abdominal cavity
First Claim
1. An abdominal retractor to be inserted into an incision made in a patient'"'"'s abdomen, said retractor comprising:
- (A) a resilient deformable generally annular shaped member, said annular member including an upper wall and a lower wall defining a generally annular recessed channel therebetween, said recessed channel being of sufficient size so as to engage abdominal tissues about the incision into said recessed channel in sandwiching relation between the upper and lower walls of said annular member, said annular member defining an access opening about the incision sized large enough for an arm member to pass therethrough into an abdominal cavity;
(B) an inflatable member disposed within said recessed channel of said annular member, said inflatable member being structured and disposed to expand upon inflation so that an inner surface of said inflatable member sealingly engages said annular member and an outer surface of said inflatable member sealingly engages the abdominal tissues;
(C) a sleeve having a proximal end joined to said annular member in surrounding fashion and adapted to extend exteriorly from the abdomen to form a cylindrical shaped passageway for introduction therethrough of the arm member; and
(D) means for tightly securing said sleeve to the arm member so as to create a seal therebetween.

Abstract
An abdominal retractor comprising a deformable annular-shaped member with an opening therethrough, which is structured and dimensioned for retracting a linear incision in the abdomen and forming the surrounding tissue into a generally circular configuration, thereby providing an access opening into the abdominal cavity large enough for a hand. The annular member is also adapted to contact the retracted abdominal tissues so as to provide a sealing engagement therebetween. A collapsible sleeve is joined to the annular member and is disposed for extension exterior to the abdomen. The sleeve is structured to enable an arm member to be sealingly yet movably enclosed therein such that a hand at the end of the arm member can be introduced through the access opening into the abdominal cavity. The retractor further includes means through which the abdominal cavity can be inflated with gas such as carbon dioxide (CO2).
