ABSTRACT:
An intra-intestinal bypass gun, which includes a tube body, a gun head unit, and an operation unit, wherein the gun head unit includes a base, a guide rod, a push rod, and a hollow anastomosis rod; the operation unit includes a rotary member, a movabler shaft, a hollow screw cap, and a quick-release connector. Rotating the rotary member causes the movable shaft, the quick-release connector, the guide rod and the hollow anastomosis rod to be moved axially upwards/downwards in opening/closing the head portion of the anastomosis rod so that a bypass tube can be secured with an anastomosis ring to the inside of the intestinal canal during an intra-intestinal bypass operation.
