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.
