Clamp device used in cooperation with endoscope

Abstract

The invention discloses a clamp device used in cooperation with endoscope. The clamp device comprises an inhaul cable (8), a sliding handle and a handle internally provided with a sliding groove, the sliding handle is sleeved with the sliding groove of the handle, the lower end of the sliding handle is fixed to the upper end of the inhaul cable (8), and the lower end of the inhaul cable (8) sequentially penetrates through an outer connecting ring (6), a middle connecting ring (5) and a tightening pipe (2) and then is fixedly connected with an inner connecting base (4); the inner connecting seat (4) is connected with a clamp; one end of the middle connecting ring (5) is connected with the external connecting ring (6), and the other end is connected with the tightening pipe (2); and a damper is arranged between the handle and the external connection ring (6).

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a clip device used in conjunction with an endoscope. Background technique [0002] Endoscopic hemostasis is an important treatment method in the treatment of gastrointestinal bleeding. The commonly used endoscopic hemostasis methods include laser coagulation, electrocoagulation, local injection of drugs for hemostasis, drug spraying, and hemostatic clip clamping. [0003] Among them, hemostatic clip clipping method has become the most effective non-surgical treatment of gastrointestinal bleeding due to its characteristics of small trauma, fast hemostasis, low incidence of rebleeding, few complications, and definite curative effect. . [0004] Clinically, there is a need for a clip device that can flexibly adjust the clamping angle, can be released simply, and can be opened again after release. [0005] 1) The realization of the rotation adjustment of the clamping angle of the e...

[0006] 2) The release function of the existing clip device is realized. Most of the separation of the clamping part and the releasing part is realized by the fracture method of the connecting piece or connecting piece, or other structural parts, and there will be fracture residue or fragments splashing; or there are many parts and the structure is relatively large. Complicated, various functions are scattered in different parts, resulting in complex assembly, poor process reliability or more parts left in the patient's body, and there are even cases where the release is not straightforward and completely leads to the failure of the operation

[0007] 3) The clip part of the existing clip device after release is fixed on the tissue. When the tissue ischemic necrosis and falls off, the clip part will fall off together; There is also a need to abandon clips that are not well released after release, and once the current clip is clamped on the tissue, it cannot be opened and loosened
