Abstract

The invention discloses a clamping device of hemostatic clips. The clamping device comprises two symmetric clamping sheets, a clamping sheet seat, a clamping sleeve, a connecting tube and a spring tube. The two clamping sheets are rotationally arranged on the front portion of the clamping sheet seat, the clamping sheet seat is arranged in the clamping sleeve in a sliding mode, a limiting block is arranged at the tail of the clamping sheet seat, and a first limiting hole and a second limiting hole corresponding to the limiting block are formed in the side wall of the clamping sleeve. The tail of the clamping sleeve is detachably connected with the connecting tube, the spring tube is arranged at the tail of the connecting tube in a sliding mode, an elastic connecting part is fixedly arranged in the spring tube, the front portion of the elastic connecting part is of a Z-shaped structure, and a through hole is formed in the tail of each clamping sheet. The middle of the elastic connecting part is fixedly sleeved with a separation tube, an elastic locking mechanism is arranged in the connecting tube and comprises at least two cantilever beams evenly distributed in the axial direction, L-shaped hook parts arranged on the front portions of the cantilever beams and fixing plates arranged at the tails of the cantilever beams, the fixing plates are fixed to the tail of the connecting tube, a through hole is formed in the middle of each fixing plate, and locking holes corresponding to the L-shaped hook parts are formed in the clamping sleeve. The clamping device has the advantages of being high in closing force, not likely to fall off and reliable in locating.

Description

technical field [0001] The invention relates to a medical device, in particular to a hemostatic clamp clamping device which enters into a human body through an endoscope and remains in the human body to achieve the purpose of hemostasis. Background technique [0002] Hemorrhage due to vascular rupture, ligated polyps, ulcers and other iatrogenic hemorrhages are common complications in internal medicine. In the past, blood transfusion and injection of coagulation drugs were the main methods of treatment for hemorrhage. In severe cases, emergency surgery was required. With the further maturity of endoscopic technology, hemostatic clip has become the main way of endoscopic hemostasis. The hemostatic clip uses the mechanical pressure generated when the two clips are closed to compress the bleeding site and block the blood flow; then, the clip is separated through the external control handle, so that the clip stays in the human body to achieve the purpose of continuous hemostasis...
