Flexible annular stapler for closed surgery of hollow organs
First Claim
1. A flexible annular surgical stapler for stapling together two parts of hollow organs, the stapler comprising(a) an elongated flexible tubular body having two ends;
- (b) a handle attached to a first end of said body;
(c) a first jaw having an axial jaw hole therethrough and two faces, a first of said faces being attached to the second end of said body;
(c) a flexible cable slidably disposed inside said body and through said jaw hole, said cable consisting of two portions, a first of said portions defining an end segment, at least part of which protrudes from the second of said faces of said first jaw; and
(d) a second jaw, forming a head, being attachable to said end segment;
said jaw hole having a non-circular cross-sectional shape and said end segment having a complementary cross-sectional shape such as to allow easy sliding of said end segment through said hole while keeping their mutual angular orientation about the axis of said hole fixed;
wherein one of said first and second jaws includes a hammer and the other of said first and second jaws includes an anvil.

Abstract
A greatly improved flexible annular stapler for joining tubular organs is disclosed. The novel stapler features greater accuracy of operation and better control by the operator, as well as additional functions, such as internal illumination and viewing facility, and accomodation of a large number of accessories, such as fibroscopes and catheters. The novel stapler, moreover, features easy attachability of both stapling jaws and easy detachability of the head. The novel features are particularly useful for closed surgery. Also disclosed are novel methods and procedures for using a flexible annular stapler and the novel features disclosed herein--particularly under conditions of closed surgery.
