Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a deep tissue magnetically controlled traction system. Background Art

[0002] The scale of the minimally invasive surgical instrument and accessory market in China has grown rapidly in the past five years. However, there are few reports on robots suitable for total endoscopic surgery in the head and neck surgery. At present, the emerging total endoscopic surgery in the head and neck or head and neck robotic surgery is a minimally invasive surgery carried out based on a limited tunnel, which can only achieve traction from the "target tissue" to the "incision" direction, while the reverse traction ability is extremely limited, and it is easy for the instruments to collide due to the "chopstick effect". Therefore, when removing deep tumors under the endoscope, how to achieve sufficient tissue traction within a limited moving space is one of the difficulties. Summary of the Utility Model

[0003] In view of the above problems, the utility model provides a deep tissue magnetically controlled traction system, which consists of a magnetic grasping part and a magnetically controlled handle part, adopts a magnetically controlled pulling method, has no connecting structure, greatly improves the ability to pull the target tissue in the reverse direction towards the incision, is more convenient to operate, and can expose the surgical field to a greater extent.

[0004] The technical solution of the utility model is as follows:

[0005] A deep tissue magnetically controlled traction system, comprising:

[0006] A grasping part for clamping the target tissue, and one of an N-pole magnetic end or an S-pole magnetic end is provided on the grasping part;

[0007] A handle part, on which the other of an N-pole magnetic end or an S-pole magnetic end is provided, and is attracted and matched with the grasping part;

[0008] In the utility model, the N-pole magnetic end is the N-pole of the magnet, and the S-pole magnetic end is the S-pole of the magnet.

[0009] In a further technical solution, the grasping part includes two clamping handles arranged crosswise and hinged by a hinge shaft, the front ends of the two clamping handles are provided with clamping heads, and the rear ends of the two clamping handles are respectively connected with matching snap-locking racks.

[0010] In a further technical solution, one of the snap-locking racks is an N-pole magnetic end or an S-pole magnetic end.

[0011] In a further technical solution, the other snap-locking rack is made of hard plastic.

[0012] In a further technical solution, the clamping head is made of stainless steel.

[0013] In a further technical solution, the handle portion includes a pull rod, a hook is provided at one end of the pull rod, and the N-pole magnetic end or the S-pole magnetic end is provided at the other end of the pull rod.

[0014] The working principle of the above technical solution is as follows:

[0015] When the deep tissue magnetically controlled traction system of the present utility model is in use, first, the magnetic force grasping forceps portion is placed under the endoscope at one end of the deep tissue to be pulled, clamped and fixed. Then, the magnetic control handle portion is used outside the body to attract the grasping forceps portion in the body, providing a reverse traction force in the incision direction, pulling the deep tissue deeper, exposing the lower and anterior boundaries of the anatomical structure to be obtained, and obtaining an operating space that is difficult to achieve under normal circumstances in head and neck endoscopic surgery.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The structure of the present utility model is simple, the processing cost is low, the operation is convenient, and it is easy to promote;

[0018] 2. The present utility model adopts a magnetically controlled traction method, without a connection structure, which can avoid the "chopstick effect" caused by too many instruments and affect the progress of the operation. At the same time, reducing the use of instruments can expose the surgical field to a greater extent. Description of the Drawings
