Abstract

A hemostatic clamp is composed of a clamping assembly, a releasing assembly and a handle assembly. The hemostatic clamp is characterized in that the clamping assembly comprises two clamp arms, a rotating pin, a sliding pin and a base sleeve; the two clamp arms are connected through the rotating pin, and the rotating pin is fixed to the base sleeve; each clamp arm is provided with a sliding groove,an elastic passage and a first positioning hole which are communicated, wherein the width of the sliding groove and the diameter of the first positioning hole are both matched with the diameter of the sliding pin, and the width of the elastic passage is smaller than the diameter of the first positioning hole; the sliding pin penetrates through the sliding grooves; the releasing assembly comprisesa connecting sleeve, an elastic clamp and a connecting piece; the front end of the connecting sleeve is embedded in the base sleeve through the elastic clamp, and the rear end of the connecting sleeve is connected with the handle assembly; the front end of the connecting piece is provided with a second positioning hole, the connecting piece is provided with a notch corresponding to the second positioning hole, and the sliding pin penetrates through the second positioning hole; the rear end of the connecting piece is connected with the handle assembly. The hemostatic clamp is simple in structure and easy and convenient to operate, and is reliable in locking and not likely to open when closed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hemostatic clip, which is applied to the closure of bleeding tissue in endoscopic operations of the digestive system (such as the gastrointestinal system and biliary system). Background technique [0002] In clinical medicine, gastrointestinal bleeding is a common clinical symptom. Common hemostatic methods include spraying hemostatic drugs, drug injection, electrocoagulation, photocoagulation, varicose ligation, and hemostatic clips. In recent years, endoscopic application of hemostatic clips has become the most effective non-surgical treatment for acute gastrointestinal bleeding due to its characteristics of less trauma, faster hemostasis, lower incidence of rebleeding, fewer complications, and definite curative effect. The working principle of the hemostatic clip is to use the working channel of the endoscope, use the delivery device to deliver the hemostatic clip to the targ...
