Problems solved by technology
[0004] However, when the hemostatic clip with the above structure is clamped, the hook a' usually cannot hook the hook groove b' smoothly, and the two are prone to misalignment, which brings inconvenience to the operation of the hemostatic clip
In addition, after minimally invasive surgery, the ligated blood vessels or bile ducts will gradually deswell, and the ligation clip will loosen after the swelling, and it is easy to fall off prematurely
In this way, it will not be able to stop the bleeding, and bile leakage and bleeding may also occur.

The invention discloses a hemostatic clip, which comprises: a first clamping arm and a second clamping arm; the first clamping arm has a first clamping surface, and the second clamping arm has a second clamping surface; one end of the first clamping arm is arranged There is a first buckle, the other end of the first clamp arm is provided with a second buckle, one end of the second clamp arm is provided with a first hook, and the other end of the second clamp arm is provided with a second hook; the first buckle Can be held in the first hook, and the second buckle can be held in the second hook, so that the hemostatic clip can clamp the blood vessel through the first clamping surface and the second clamping surface; the first buckle The structure of the hook is different from that of the second buckle, and the structure of the first hook is different from that of the second hook. The invention is easy to operate, and when the blood vessel is hemostasis, the first clamping arm and the second clamping arm can be closed smoothly by means of buckles and hooks. And after being closed, the first clamping arm and the second clamping arm can provide a continuous clamping force, which is not easy to loosen.
Description
Technical field[0001]The present invention relates to the field of medical devices, in particular, relates to a hemisolic clip.Background technique[0002]Minimally invasive surgery refers to a new technique for performing operations in human body in human body through laparoscopic and thoracoscopic. Since minimally invasive surgery has a small trauma, the pain is light, the recovery is superior, and in medical, minimally invasive surgery is gradually popular. In minimally invasive surgery, hemostasis is needed to stop bleeding.[0003]Such asfigure 1 As shown, the existing hemostatic clip includes a first pinch arm A and a second pinch arm B, wherein the end of the first clip arm A is provided with a hook A ', the end of the second clip arm B. Set with hooks B '. When used, the stopper is placed in a splitter, and is hit by the hair cleaning, and the clamping of the stopper is achieved. Specifically, when the first pinch arm A and the second pinch arm B are clamped for hemostasis, the ...
