Magnetic anastomosis device for tissue clipping under digestive endoscopy

The utility model discloses a magnetic anastomosis device for tissue clipping under a digestive endoscope. The magnetic anastomosis device adopts the design scheme that an anastomosis magnet is composed of two semi-annular magnets, a step-shaped transparent cap with a sliding groove and a detachable push rod device fixed on tissue grasping forceps. Wherein the anastomosis magnet can be nested on a step at the front end of the transparent cap, the detachable push rod device can be fixed on a rod body of the tissue grasping forceps and is embedded in a sliding groove of the transparent cap, after the tissue grasping forceps clamp fistula tissue under an endoscope, the tissue grasping forceps are pulled backwards, the push rod device excites the two semi-annular magnets in the sliding groove to change the state, and the state of the two semi-annular magnets is changed. The arc-shaped part of the magnet can clamp and close the orificium fistulae, and after the orificium fistulae heals, the magnet automatically fa
