Abstract: An absorbable and unidirectionally compressible intestinal anastomosis device, including a first through pipe portion and a second through pipe portion respectively including large ends and small ends; the large ends are used for fixing an intestinal canal; and the small end of the second through pipe portion is inserted into the small end of the first through pipe portion. The two large ends are drawn close to each other to achieve an intestine-intestine anastomosis. The outer sides of circular rings at the ends of the small ends of the first through pipe portion and the second through pipe portion are provided with gradually-expanded elastic horn-shaped openings. The device can make two stapled intestinal canals rest relatively, thereby avoiding adjustments required in other assembling modes.

Abstract: A degradable intestinal complete diversion device, made of biocompatible degradable materials, includes a circular tube constituting the bridge for the intestinal incisions on both sides to crawl towards each other and anastomosed; the end of the circular tube is connected with a gradually expanding flared opening, and a convex ring for binding the broken end of the intestine is arranged on the circular tube near each flared opening, and the hollow inner cavity of the circular tube is provided with a barrier film for blocking the hollow inner cavity. The invention used with a drainage tube realizes complete intestinal diversion without secondary operations of stoma reintroduction.

Abstract: An absorbable and unidirectionally compressible intestine-intestine stapler, comprising a first through pipe portion and a second through pipe portion. The first through pipe portion can move back and forth relative to the second through pipe portion, and the first through pipe portion and the second through pipe portion are inseparable. The first through pipe portion and the second through pipe portion respectively comprises large ends and small ends; the large ends are used for fixing an intestinal canal; and the small end of the second through pipe portion is sheathed into the small end of the first through pipe portion. The two large ends are consistent in size; when the first through pipe portion moves relative to the second through pipe portion, the two large ends are draw close to each other to achieve an intestine-intestine and end-end anastomosis.
