Double-motor clip applicator

Abstract

The invention relates to a double-motor clip applicator. The double-motor clip applicator comprises a working head as well as a first motor, a second motor, a first drive assembly, a second drive assembly and a clip bin assembly which are arranged in the working head, wherein the clip bin assembly comprises a clip bin for accommodating ligation clips and a clamp arranged on one side of the clip bin, a trigger rod and a clip pushing rod are also arranged in the working head, the trigger rod is connected with the clamp to open or trigger the clamp, the first drive assembly is connected with thetrigger rod and the first motor, the second drive assembly is connected with the clip pushing rod and the second motor, and the clip pushing rod pushes the ligation clips in the clip bin to enter theclamp. The double-motor clip applicator solves the problems that a traditional clip applicator needs a shaft to complete clip sending and trigger actions, has higher dependence and restriction relations and causes misoperation easily. Through double-motor control, the double-motor clip applicator is simpler to operate, has a higher degree of freedom and reduces the error rate.

Description

technical field [0001] The invention relates to a clamp applier with double motors, which belongs 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...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a dual-motor clip applier, which solves the problem that the traditional clip applier needs to complete the clip feeding and firing actions through one shaft, which has a strong dependence and restriction relationship, and is likely to cause operational errors; However, the present invention is controlled by dual motors, which makes the operation simpler, has a higher degree of freedom, and reduces the error rate
