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

Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0022] The invention discloses a magnetic anchoring system for electromagnetically controlled laparoscopic surgery built-in grasping forceps clutch, which mainly includes built-in grasping forceps, operating forceps and an external anchoring device.

[0023] The structure of the built-in grasping forceps is as follows figure 1 As shown, it includes a hollow sleeve rod 11 , and the tail end 19 of the hollow sleeve rod is cylindrical, and its size is sufficient to poke a hole through the abdominal wall of 10 mm, and is larger than the diameter of the hollow sleeve rod 11 . There is a hollow cylindrical connecting magnet 12 inside the hollow sleeve rod tail end 19, and a shrapnel 15 is arranged inside the hollow sleeve rod 11. A spring 14 is arranged outside the shrapnel 15, and a pin 13 is arranged in the hollow sleeve rod 11, and the two ends of...

Abstract

The invention provides a magnetic anchoring system for an electromagnetic control laparoscope operation with combination and separation of gripping tongs. The magnetic anchoring system comprises the internal gripping tongs, operating tongs and an in-vitro anchoring device, the internal gripping tongs comprise a hollow sleeving rod, a connecting magnet, an elastic sheet, a spring, a damage-free tongs clamp head and the like, the operating tongs comprise an operating sleeving rod, an operating rod, an electromagnetic iron core and the like, by arranging an electromagnet at the head end of the operating rod and arranging a permanent magnet at the tail end of the internal tongs, the combination and separation of an internal gripping head clamp are conveniently controlled, and through the internal operating rod, the head end of the internal tongs is controlled to clamp tissues.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a magnetic anchoring system for electromagnetically controlled laparoscopic surgery built-in grasper clutch. 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 the end of...
