Anti-shedding hemostatic clamp

Abstract

The invention discloses an anti-shedding hemostatic clamp comprising a first clamp arm and a second clamp arm connected through an elastic hinge. Both the first clamp arm and the second clamp arm are in arc structures and match with each other in radian. The anti-shedding hemostatic clamp is characterized in that the free end of the first clamp arm is provided with a hook portion, the free end of the second clamp arm is provided with a hook groove matching with the hook portion, the part, more than 0.01mm away from the hook groove, of the outer surface of the second clamp arm is provided with at least one positioning member extending along the width-wise direction of the second clamp arm, and the hook portion is provided with locking members matching with the positioning members. A group of female-male fastening structures and hook-groove locking structures can produce sufficient locking force so that a blood vessel or tube tissue closed by clamping can be stably and stably closed.

Description

technical field [0001] The present invention relates to a medical device, more specifically, the present invention relates to a hemostatic clip that prevents falling off, which is used for ligation and hemostasis in minimally invasive surgery such as laparoscopic surgery and other small field of view operations. Background technique [0002] Fluid leakage and bleeding are involved in many parts of the human body during surgery, and the hemostatic clip is a device used for ligation and hemostasis of pipeline tissue. In particular, the ligation and hemostasis of minimally invasive surgery such as laparoscopic surgery and other small field of view operations can be quickly realized. [0003] For a long time, there were only metal ligation clips, silver clips first, and then tantalum clips, steel clips and titanium clips, and the metal titanium clips were used more. But titanium clips have many unavoidable disadvantages, such as: [0004] 1) Generate artifacts and affect CT, M...

AI Technical Summary

Problems solved by technology

[0006] 3) There is a possibility of loosening, falling off or wandering;

[0007] 4) The scope of application is limited, and it is not easy to clamp large pipeline tissues and inflamed tissues. In case of obvious inflammation of surrounding tissues, thickening of edema, or fibrosis and hard pipelines, metal titanium clips often cannot be firmly clamped;

However, there are still some problems in use, mainly in that the firmness is not enough

During the use of the hemostatic clip, the locking part will slip off
