Hemostatic clamp with four-bar structure

Abstract

The invention relates to a hemostatic clamp with a four-bar structure, which comprises a clamp head part, an outer tube part, an inhaul cable and a handle, wherein the inhaul cable is connected with the handle through a sliding ring, the outer pipe part is fixedly connected with the handle, the clamp head part consists of two clamp heads and two connecting poles, the clamp handle and the connecting pole of each clamp head form a four-bar structure, the two clamp heads are pin-jointed on a clamp head seat, the clamp head seat is connected with the outer tube part, and the two connecting poles are pin-jointed on a pull rod arranged on the front end of the inhaul cable. According to the hemostatic clamp, the sliding ring slides on the handle to pull the inhaul cable to move front and back; and the pull rod drives the four-bar structure to move, thus the clamp heads are closed and opened. The hemostatic clamp can be repeatedly flexibly opened and closed, and is most suitable for a treating device for hemostasis in body cavity.

Description

technical field [0001] The invention relates to a surgical instrument for medical examination, specifically a hemostatic clip with a four-link structure, which is used to close the two edges of a wound of a biological tissue or prevent small blood vessels from bleeding under an endoscope. One of the necessary instruments for endoscopic minimally invasive surgery. Background technique [0002] In clinical medicine, gastrointestinal bleeding is a common clinical symptom. Endoscopic hemostasis has increasingly become one of the preferred methods of hemostasis. And among the various hemostasis methods adopted at present, hemostatic clip hemostasis has the advantages of small trauma, fast hemostasis speed, few complications, and definite curative effect, and has become an important method of non-surgical treatment for the treatment of gastrointestinal bleeding. The basic principle is to use special metal small hemostatic clips to directly clamp the bleeding blood vessels or tor...

Problems solved by technology

Its effectiveness has been affirmed, but there is a very important but unsolvable problem in the traditional hemostatic clips on the market in actual operation, that is, it cannot be closed repeatedly, and a hemostatic clip device can only be closed once
