Hemostat

Abstract

The invention discloses a hemostatic clip, which comprises: a first clamp arm and a second clamp arm; one end of the first clamp arm is connected with one end of the second clamp arm, the other end of the first clamp arm is provided with a buckle, and the second clamp arm The other end of the two clamping arms is provided with a card slot, the first clamping arm has a first clamping surface, the second clamping arm has a second clamping surface opposite to the first clamping arm, the first clamping surface and the second clamping When the holding surface is clamped, the buckle is accommodated and installed in the slot in an interference manner. The buckle is a protruding structure formed on the other end of the first clamping arm, and the buckle is formed in a depression on the other end of the second clamping arm. Grooved structure at one end. The invention is easy to operate, and the first clamping arm and the second clamping arm can be smoothly closed when the blood vessel is stopped. Moreover, the first clamping arm and the second clamping arm can provide continuous clamping force, and loosening is not easy to occur. The invention is an absorbable hemostatic clip, which can be absorbed by the human body after the hemostasis is completed, so as to prevent the hemostatic clip from being left in the human body and causing adverse effects on human tissues.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemostatic clip. Background technique [0002] Minimally invasive surgery refers to a new technology that performs surgery in the human body through endoscopes such as laparoscopy and thoracoscopic surgery. Because minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery, minimally invasive surgery has gradually gained popularity in medical treatment. In minimally invasive surgery, it is necessary to use a hemostatic clip to stop the blood vessel from bleeding. [0003] Such as figure 1 As shown, the existing hemostatic clip includes a first clamp arm 1 and a second clamp arm 2, wherein, the end of the first clamp arm 1 is provided with a hook 1 ′, and the end of the second clamp arm 2 A hook groove 2' is provided. When in use, the hemostatic clip is placed in the clip applier, and is fired by the clip applier to realize the c...

Problems solved by technology

[0004] However, when the hemostatic clip with the above structure is clamped, the hook 1' usually cannot hook the hook groove 2' 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.
