Medical clamp

Abstract

The invention provides a medical clamp which comprises a clamping device, wherein the clamping device comprises a clamping arm, a small steel sleeve, a transmission shaft and a location sleeve; the clamping arm is clamped to the transmission shaft, the clamping arm and the transmission shaft are arranged in the location sleeve, one end, close to the clamping arm, of the location sleeve is tightlyhooped by the small steel sleeve, a through hole is arranged at one end, close to the clamping arm, of the transmission shaft, and an elastic coil penetrates through the hole to achieve a traction effect in operation. The medical clamp disclosed by the invention can be applied to operation under endoscopes, the whole structure and a use method of a medical clamp traction system are further improved, the traction direction is more flexible, the situation of repeatedly entering and exiting the endoscopes is avoided, the medical clamp is safer and more convenient to use, and the damage risk to the tongue root, pars laryngea pharyngis and gastrointestinal mucous membranes of other positions is avoided.

Description

technical field [0001] The invention belongs to the technical field of endoscopic operation aids, in particular to a medical clip. Background technique [0002] Titanium clips are often used in endoscopic surgery. At present, titanium clips have basically replaced silver clips for clamping and ligating tissues. The conventional titanium clip system consists of two parts: a clamping device and a release device. During the operation, the clamping device clamps the tissue and is separated from the release device. However, in endoscopic submucosal dissection (ESD), because the tissue to be treated is often close to the tissue mucosal wall, or even penetrates into the mucosal wall to a certain depth, and the existing titanium clip has no position for pulling after it is released, so When carrying out relevant operation, just there is the problem of inconvenient operation. Therefore, if there is no pulling device, it will affect the accuracy and efficiency of the doctor's operat...

AI Technical Summary

Problems solved by technology

In terms of traction direction, it can only be pulled outward, and it is difficult to move in other directions such as lateral direction

When entering, the traction wire must enter the human body together with the endoscope outside the clamp channel. It is very difficult to enter the deep digestive tract (such as the position of the right colon), and even if it can enter, it is easy to damage the digestive tract mucosa

When the next one is to be placed, the endoscope must be pulled back from the digestive tract, which is very inconvenient for the doctor, unsafe and very inefficient
