Intestinal Anastomotic Surgery Aid

Abstract

An intestinal anastomotic surgery aid 1 is constituted with a cylindrical portion 40 for covering the proximal end side of an engaging rod 28 , and a cover portion 41 that extends from the cylindrical portion 40 towards the distal end side of the engaging rod 28 . The proximal end part of the cylindrical portion 40 is inserted to a recessed portion 26 of a device main body 21 to be held to the device main body 21 . The anus-side piece of the intestine is tied with a suture to be held to the outer face of the cylindrical portion 40.
