Abstract

An extension mounting apparatus on which a bowel anastomosis ring device may be mounted in prefixed position to facilitate handling, insertion and closure in bowel ends to be anastomosed may be advantageously removably attached to an inserter to provide an applicator which enables insertion in the bowel and manipulation from a point exterior of the area to be anastomosed so as to cause the bowel anastomosis ring device halves to become controllably connected to couple the bowel ends to be joined together in contiguous abutting relationship. A method of performing low colorectal anastomosis using the bowel anastomosis ring device and closing the mating ring halves by manipulating the applicator exteriorly of the anus involves passing the inserter portion of the applicator from the interior of the rectum to the exterior of the anus so that placement is always from the clean area of surgery and anastomosis to the dirty and contaminated end.

Claims

1. In a method for surgically anastomosing tubular anatomic members including clamping the tubular anatomic members to be joined between mating halves of a clamping device and utilizing a longitudinal inserter inserted into at least one of the tubular members for positioning at least a portion of the clamping device for the anastomosis, the improvement comprising inserting the clamping device between the tubular anatomic members at the site of the desired anastomosis;

causing the longitudinal inserter to extend into at least one of the tubular members by proceeding from the anastomosis site into the tubular member; and

further causing the longitudinal inserter to project through an opening in the tubular member into which it is extended wherein the opening through which the inserter projects in a natural body orifice.

2. In a method for surgically anastomosing sections of the colon including clamping the colonic member to be joined between mating halves of a clamping device and utilizing a longitudinal inserter inserted into at least one of the members for positioning at least a portion of the clamping device for the anastomosis, the improvement comprising inserting the clamping device between the colonic members at the site of the desired anastomosis;

causing the longitudinal inserter to extend into at least one of the members by proceeding from the anastomosis site into the tubular member;

further causing the longitudinal inserter to project through an opening in the colonic member into which it is extended; and

the mating halves of said clamping device come together by manipulating a shaft that draws at least one of said halves toward the other half, the means for manipulating said shaft located adjacent the proximal end of said shaft, wherein the clamping device is a bowel anastomosis ring device having ring-like halves and at least one-half is mounted on an applicator, the applicator is caused to enter into the lower colon portion from the site of the anastomosis, through the rectum and out of the anus and the ring halves are caused to come together by manipulating the applicator exteriorly of the anus.

3. A method for surgically anastomosing sections of the colon as claimed in claim 2 wherein said manipulating means are separable from said shaft.
