Method and instrument assembly for removing organ
First Claim
1. A method for removing an organ internal to a patient, said organ being coupled to internal tissues via at least a mass of connective tissue, the method comprising the steps of:
- providing a surgical instrument including a flexible loop and a flexible web member connected to said loop to form a capture pocket, said loop defining a mouth opening of said pocket;
passing said loop around a portion of the organ, thereby enclosing the organ portion in said capture pocket;
subsequent to said step of passing, severing connective tissue between the organ and adjacent tissues;
maintaining said organ portion surrounded by said capture pocket during said step of severing connective tissue; and
upon a severing of some of the connective tissue between the organ and the adjacent tissues, shifting said loop relative to the organ to enclose a greater portion of the organ in said capture pocket.

Abstract
A method for removing a gall bladder comprises the steps of (a) providing a surgical instrument including a flexible loop and a flexible web member connected to said loop to form a capture pocket, the loop defining a mouth opening of the pocket, (b) closing the cystic duct, (c) severing the cystic duct, and (d) passing the loop around a portion of the gall bladder including a closed and severed segment of the cystic duct, thereby enclosing the gall bladder portion in the capture pocket. The method further comprises the steps of (e) severing connective tissue between the gall bladder and the adjacent liver subsequently to the passing of the loop around the bladder, (f) maintaining the gall bladder portion surrounded by the capture pocket during the severing of the connective tissue, and (g) shifting the loop relative to the gall bladder to enclose a greater portion of the gall bladder in the capture pocket upon a severing of some of the connective tissue between the gall bladder and the adjacent liver. The method is adaptable to removing other internal organs, particularly organs which are coupled to adjacent tissue masses via connective tissue.

16. A method for removing a gall bladder, comprising the steps of:
-
piercing an abdominal wall of a patient to form a pair of openings in said abdominal wall; disposing a first tubular cannula in one of said openings; disposing a second tubular cannula in another of said openings; providing a first surgical instrument including a flexible loop and a flexible web member connected to said loop to form a capture pocket, said loop defining a mouth of said pocket; inserting said loop and said web member through said first tubular cannula into the abdomen of the patient; inserting a second surgical instrument through said second tubular cannula into the abdomen of the patient; passing said loop around a portion of a gall bladder including a closed and severed cystic duct segment, thereby enclosing the gall bladder portion in said capture pocket; subsequent to said step of passing, using said second surgical instrument to sever connective tissue between the gall bladder and the adjacent liver; maintaining said gall bladder portion surrounded by said capture pocket during said step of using said second surgical instrument; and upon a severing of some of the connective tissue between the gall bladder and the adjacent liver, shifting said loop relative to the gall bladder to enclose a greater portion of the gall bladder in said capture pocket. - View Dependent Claims (17, 18, 19, 20)
