Improved hemostasis clamp for being used under endoscope and clamp part thereof

Abstract

The invention relates to an improved hemostasis clamp for being used under an endoscope and a clamp part thereof. The clamp part comprises clamping pieces, a clamp tube, a stop pin, a connecting pin,a clamping piece fixing base and a connecting tube; the clamping piece fixing base is arranged inside the clamp tube and can move back and forth, an open deformation hole is formed in the tail of eachclamping piece, the connecting pin runs through the deformation holes in the two clamping pieces and then is fixedly connected with the front end of the clamping piece fixing base, and one side of each deformation hole in the tail of the clamping piece is provided with a protrusion turned outwards; an annular stop step is arranged at the tail of the inner wall of the clamp tube, when the two clamping pieces are clamped, the protrusions at the tails of the clamping pieces are clamped to the stop step, and the stop pin is fixed to the front portion of the clamp tube and therefore the clamping piece fixing base is limited from sliding out of the clamp tube. By adopting the technical scheme, the purposes that part breakage happens from beginning to end, and no fragment residue exists; the tails of the clamping pieces are connected with a release part, the maximum space utilization is obtained, after clamping is released, and the total length is the smallest.

Description

technical field [0001] The invention relates to a hemostatic clip used under endoscopic inspection, in particular to a hemostatic clip and its clamp part for clamping tissue under endoscopic inspection to close wounds, stop bleeding or prevent delayed bleeding. Background technique [0002] With the development of endoscopic technology and other related technologies, endoscopic hemostasis has become the first choice for the treatment of gastrointestinal bleeding. Currently commonly used endoscopic hemostasis methods include laser coagulation, electrocoagulation, local injection of drugs to stop bleeding, drug spraying and hemostatic clip clamping. 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. . However, the width of the opening of the current hemostatic clip...

Problems solved by technology

The clamping arm of the device is slotted, which increases the processing difficulty and cost, and the special shape of the clamping arm makes the clamping arm less elastic, and the clamping is not firm; in addition, the deformation of the wire buckle makes the wire buckle and clamp The arm is loose. Due to the opening gap of the steel wire buckle, it may accidentally loosen when the clip body is repeatedly pushed, which will affect the stability of use.

[0007] In the patent literature published by the United States with the patent application number US8062311B2, a hemostatic clip that requires a yoke to constrain the clip to advance and stop, and the yoke remains in the patient's body, has a barb hole on the clamp tube. There is also the problem of inconvenient use
