Clamp Assembly and Clip Applier

Abstract

The invention relates to a clip bin assembly and a clip applicator. The clip bin assembly includes a clip bin, a clip feeding device and a clamp arranged on one side of the clip bin. A bin for placing the ligation clip and the clip feeding device is formed in the clip bin. cavity, and the clip feeding device includes an elastic member and a push clamp block for pushing the ligation clip in the chamber to move. When the clamp is opened, the elastic member drives the push clamp block to move toward the clamp through its elastic force. The clip applier includes the above-mentioned clip chamber assembly, firing device, driving device and control circuit, the firing device includes a push rod, the push rod connects the driving device and the clip chamber, and the push rod is arranged on the other side of the clip chamber relative to the clamp , the control circuit is connected with the driving device to control the driving device to drive the push rod to drive the movement of the clamp bin, thereby controlling the opening and closing of the clamp. The clip magazine component and the clip applier solve the problems that the existing clip applier cannot realize continuous firing, which causes inconvenient use, increases operation time, and the like.

Description

technical field [0001] The invention relates to a clip bin assembly and a clip applier, belonging to the field of medical instruments. Background technique [0002] In order to fully expose the surgical field of view during the surgical operation, it is necessary to ligate the target tissue in the incision 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. However, the existing clip applicators are usually single-shot, and can only clamp one ligation clip at a time, and the ligation clip needs to be repositioned after the blood vessel is clamped by the ligation clip. However, during the surgical operation, multiple ligation clips are required to complete hemostasis. Therefore, conventional clip appliers need to enter and exit the puncture dev...
