Forceps mouth assembly and clip applier

Abstract

The invention relates to a forceps mouth assembly and a clip applier, and belongs to medical surgical devices. The forceps mouth assembly comprises a clip mechanism, wherein the clip mechanism comprises a first clip and a second clip which are oppositely arranged, and the first clip and the second clip move between an open position and a closed position to clamp a ligature clip in the clip mechanism; a symmetric axis is formed between the first clip and the second clip, the forceps mouth assembly further comprises a moving part capable of moving along the direction of the symmetric axis relative to the clip mechanism, and a guide closing mechanism formed between the moving part and the clip mechanism; the guide closing mechanism comprises a guide column formed on one of the moving part and the clip mechanism and guide grooves formed in the other one of the moving part and the clip mechanism, and the guide column moves in the guide grooves to form a first position corresponding to the opening position and a second position corresponding to the closing position; and the guide column moves between the first position and the second position to cause the first clip and the second clip to move between the opening position and the closing position.

Description

technical field [0001] The invention relates to a jaw assembly and a clip applier, belonging to medical operation devices. Background technique [0002] In order to fully expose the surgical field during the surgical operation, it is necessary to ligate the blood vessels around the target tissue to prevent bleeding. Hemostasis technology has become one of the cores of basic surgical techniques. Surgical operations on any part of the human body almost without exception involve bleeding and hemostasis. Generally, clip applicators are used to close hemostasis with ligature clips. When the clip applier in the prior art is in use, the closure of the clamp is achieved by squeezing the side of the clamp through the outer sleeve, and the outer sleeve is located at the end of the clamp, which will cause crossing, twisting and abnormal shape when the ligation clip is closed . Contents of the invention [0003] The object of the present invention is to provide a jaw assembly which ...
