基于磁锚定系统的电磁控制腹腔镜手术内置抓钳离合系统的设计

Design of Magnetic Clutch System for Electromagnetic Control Laparoscopic Surgery Based on Magnetic Anchoring System

借助磁锚定技术可减少腹腔镜手术戳孔数量。腹腔镜磁锚定系统主要包括体外锚定磁体和内置抓钳离合系统。电磁控制腹腔镜手术内置抓钳离合系统主要包括内置抓钳和操作钳两部分。该文设计在内置抓钳尾端设置永磁体,在操作钳头端设置电磁装置,通过切换电磁装置电源正负极可改变电磁装置的磁场方向从而来控制操作钳与内置抓钳的分离与结合。该系统设计具有巧妙易加工制造、操作简单易行等优点。

Magnetic anchor technique can reduce the number of trocar in laparoscopic surgery.The laparoscopic magnetic anchor system consists of an external anchor magnet and the magnetic clutch system.Electromagnetic control laparoscopic surgery clutch system includes the internal grasper and the operating forceps.In this design,a permanent magnet is set at the tail of the internal grasper,and an electromagnetic device is installed at the head of the operating forceps.The magnetic field direction of the electromagnetic device can be changed by switching the positive pole and the negative pole of the electromagnetic device,so as to control the separation and combination of the operating forceps and the internal grasper.The design of this system is ingenious,easy to manufacture and the operation is simple.
