A novel ligation device comprises a ligation device part and a ligation ring matched to the ligation device part. The ligation device part comprises a draw hook (1), a spring tube (2), a draw filament (3), a protection tube (4), a guide tube (5), a boosting tube (6) and a handle (7). The draw hook (1) is connected to the draw filament (3) which is connected to the boosting tube (6). The boosting tube (6) and the grip (13) of the handle (7) are connected to form a conveying part. The spring tube (2) is connected to the guide tube (5). The guide tube (5) is connected with the slide bar buckle of the handle (7) to form a conveying outer tube. The ligation ring comprises a ligation loop (8), a sleeve (9) and a draw ring (10). The ligation loop (8) and the draw ring (10) are molded by manufacture tools to form an integral body. The sleeve (9) is loaded on the ligation loop to form an integral body by one end of the draw ring (10). The novel ligation device has simple structure, reliable hooking and small tissue damage. The polypus is removed completely, the mucous membrane is repaired rapidly, the curative effect is good and the obvious complication is prevented. The operation is simple, rapid and safe. The equipment is simple, and the cost is low and economic.La présente invention concerne un nouveau dispositif de ligature comprenant une partie de dispositif de ligature et un anneau de ligature allant de pair avec la partie de dispositif de ligature.
