Embodiment Construction

[0031] The present invention includes a target magnet and an anchor magnet capable of attracting the target magnet, and the structure of a specific embodiment is as follows:

[0032] see figure 1 , 2 , 3. The target magnet 1 is composed of two parts: a target magnet shell 5 made of permalloy material with a tail hanging 4 and a cylindrical magnetic core 2 . The target magnet shell 5 is U-shaped, with a wall thickness of 1mm. The tail end is provided with a tail hanger 4, and the tail hanger 4 is provided with a connecting hole 3 with a diameter of 1mm. The silk thread can pass through the connecting hole 3 and can be tied together with a miniature soft tissue clamp. The magnetic core 2 is a cylindrical structure, and the ratio of its height to diameter is 1.5-2:1. The magnetic core 2 is made of N48 sintered NdFeB permanent magnet material. The magnetic core 2 and the target magnet shell 5 are both electroplated with nickel or nitrogen Titanium oxide surface coating, the two ...

Abstract

The invention relates to a magnetic anchoring device for endoscopic submucosal dissection and a using method of the magnetic anchoring device. The magnetic anchoring device provided by the invention includes a target magnet and an anchoring magnet capable of attracting the target magnet, wherein the target magnet includes a magnetic core and a target magnet shell, and the magnetic core is nested in the target magnet shell. The magnetic anchoring device is simple in operation, reliable in mucosa pulling effect and capable of flexibly adjusting a pulling direction and a pulling force.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a magnetic anchoring device for endoscopic mucosal dissection and a method for using the same. Background technique [0002] With the popularization of gastrointestinal endoscopy, the early diagnosis rate of gastrointestinal tumors has been significantly improved, and patients have obtained the opportunity for early treatment, and the survival period has also been significantly prolonged. Clinical studies have shown that endoscopic submucosal dissection (ESD) for early gastrointestinal cancer can achieve the same therapeutic effect as traditional surgery. At the same time, endoscopic mucosal dissection has less trauma, faster postoperative recovery, and significantly reduces the hospital stay and medical burden of patients. It is an early treatment method for the digestive tract with great clinical potential. However, endoscopic mucosal dissection has high requirements for the ope...
