本发明涉及一种医疗器械。The invention relates to a medical device.
外科手术过程中为充分暴露手术视野，需要对目标组织周围血管进行结扎，以阻止出血。止血技术已经成为了外科手术基本操作技术的核心之一，人体任何部位的外科操作几乎无一例外地涉及到出血与止血，一般使用施夹钳结扎夹闭合止血。但是，在手术过程中，由于夹钳数量的限制，使得操作者需要多次进行施夹操作，这样既降低了工作效率，增加手术时间，增大患者出血量，延长患者恢复时间。所以，连续送夹的施夹钳应运而生。In order to fully expose the surgical field of vision during the surgical procedure, the blood vessels around the target tissue need to be ligated to prevent bleeding. Hemostasis technology has become one of the cores of basic surgical operation techniques. Surgical operation of any part of the human body involves bleeding and hemostasis almost without exception. Generally, ligation clips are used to close the hemostasis. However, in the course of surgery, due to the limitation of the number of clamps, the operator needs to perform multiple clipping operations, which reduces the working efficiency, increases the operation time, increases the bleeding volume of the patient, and prolongs the recovery time of the patient. Therefore, the clamp applicator that continuously feeds the clamp came into being.
现有技术中，有的连续送夹的施夹钳的夹仓部分为可拆卸形式，那么，如何识别夹仓安装或拆卸状态成为此类施夹钳的难题。In the prior art, some of the clamping bins of the clamping tongs that continuously feed the clamps are in a detachable form. Then, how to identify the installation or removal state of the clamping bin has become a problem for such clamping tongs.
