A magnetic anchoring system with built-in grasper clutch for magnetically controlled laparoscopic surgery

Abstract

The invention relates to a magnetic anchoring system realizing separation and combination of built-in gripping tongs for magnetic control laparoscopic surgery. The magnetic anchoring system comprisesthe built-in gripping tongs, operation tongs and an in-vitro anchoring device, wherein the built-in gripping tongs comprise a hollow sleeve rod, a first permanent magnet, an elastic plate, a first spring, a non-damage tongs clamp head and the like; the operation tongs comprise an operation sleeve rod, a built-in sleeve rod, an operating rod, a second permanent magnet, a second spring and the like;the in-vitro anchoring device comprises a cylindrical anchoring magnet and an anchoring magnet shell, and is used for pulling the built-in gripping tongs to move in the abdominal cavity in vitro. According to the magnetic anchoring system realizing separation and combination of the built-in gripping tongs for the magnetic control laparoscopic surgery, the permanent magnet is arranged at the headend of the operation sleeve rod, the permanent magnet is also arranged at the tail end of the built-in gripping tongs, so that the combination and separation of the built-in gripping tongs can be conveniently controlled, a push rod is arranged in the operation sleeve rod, so that the head end of the elastic plate is controlled to grip the tissue.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a magnetic anchoring system with built-in grasper clutch for magnetically controlled laparoscopic surgery. Background technique [0002] Laparoscopic minimally invasive surgery is an important trend in the development of abdominal surgery. By placing built-in magnetic graspers in the body and placing anchor magnets on the abdominal wall to pull the built-in magnetic graspers, the number of abdominal wall poking holes in laparoscopic surgery can be reduced to achieve ultra-minimally invasive purposes. Currently, laparoscopic tissue graspers used in surgery are of an integrated structure, which cannot realize the function of built-in graspers under magnetic anchoring. For this reason, the patent "a built-in grasper system under the magnetic anchoring system" (patent number 201610146126.9) has designed a built-in grasper for the magnetic anchoring system. At ...

AI Technical Summary

Problems solved by technology

The design of this invention can meet the requirements of the anchoring system for the built-in grasping forceps, but the built-in grasping forceps of this design will have difficulty in combining and separating the built-in grasping forceps during specific use, and the built-in grasping forceps need to be used repeatedly and alternately to push and hold tissues and organs. Controlled by a lever, the operation is more cumbersome
