Abstract
An intestinal anastomosis gun is disclosed including a gun barrel, a gun head unit formed of a push rod and a hollow anastomosis rod, and an operating mechanism formed of a rotary member, a center shaft and a hollow screw cap. The center shaft and the anastomosis rod are moved axially upon rotary motion of the rotary member, thereby causing the head of the anastomosis rod to open or close. The intestinal anastomosis gun is inserted through the anus into the intestinal canal of the large intestine or rectum after installation of an anastomosis ring and a synthetic detour tube, enabling the synthetic detour tube to be fastened to the intestinal canal during an intestinal detour operation.
