Tissue clamp

Abstract

The invention relates to a tissue clamp, and belongs to medical equipment for surgical implants clinically. The tissue clamp comprises an upper clamp body, a lower clamp body and an adjusting hole, wherein the upper clamp body and the lower clamp body are an arched upper clamp body and an arched lower clamp body which are mutually matched and bent in the same direction; a clamping groove is formed at the head of the upper clamp body; a clamp is arranged at the head of the lower clamp body; the adjusting hole is formed at the connecting part of the upper clamp body and the lower clamp body; an inner side face of the upper clamp body is provided with a first outer tooth-shaped anti-slip lug boss and a first inner tooth-shaped anti-slip lug boss; an inner side face of the lower clamp body is provided with a second outer tooth-shaped anti-slip lug boss and a second inner tooth-shaped anti-slip lug boss; the two groups of outer tooth-shaped anti-slip lug bosses and inner tooth-shaped anti-slip lug bosses form a tooth-shaped engaged structure so as to prevent tissues from slipping; a reinforced hemostatic groove is formed inside the upper clamp body; and a reinforced hemostatic convex groove is formed inside the lower clamp body. The tissue clamp has reasonable design, and the tooth-shaped engaged structure is matched with a mutually self-locked fastening structure to solve the problem that a deformed occlusion part of a U-shaped titanium clamp is not provided with a self-locked structure to cause slippage.

Description

technical field [0001] The invention relates to a tissue clip, which is a medical device clinically belonging to surgical implants. Background technique [0002] In human surgery, once a lesion is found in the human body, it needs to be resected. During the resection, the organs in the body need to be temporarily closed, or even permanently closed. [0003] Existing technologies: [0004] One is to suture and close the closed parts in the body. The disadvantage is that the operation time is long and the operation is difficult. Doctors are required to have strong suture and knotting skills. Bleeding and slow wound healing. [0005] The second is other tissue clips, such as commonly used metal clips (titanium clips, silver clips), usually U-shaped metal clips. In clinical use, use a special tissue clip applier, insert the metal clip into the clip of the tissue clip applier head, and then release it, that is, clamp the clip of the tissue clip applier, and then exit the tissu...

AI Technical Summary

Problems solved by technology

The concave-convex groove strengthens the hemostatic structure and the self-locking buckle structure solves the unsafe situation of conventional tissue clips, which cause bleeding at the closure due to the insecure locking of the forming gap after clipping
