Endoscopic annular tissue closure function enhancing magnetic bead assembly

Abstract

The invention discloses an endoscopic annular tissue closure function enhancing magnetic bead assembly. The assembly comprises magnetic parts, and each magnetic part comprises an implantable shell and a magnet, the implantable shell is arranged in annular tissue, and the magnet is movably arranged in the implantable shell. The magnets can freely move in the implantable shells, and by placing the plurality of magnetic parts in the annular tissue, the magnets in different implantable shells can automatically adjust magnetic poles, so that the plurality of magnetic parts attract each other to improve the closure capacity of the annular tissue. The magnets are wrapped by the implantable shells, and the implantable shells meet biocompatibility, so that the magnets can be prevented from being in direct contact with the annular tissue. The at least two magnetic parts which are connected in an adsorption manner can be implanted into the annular tissue in sequence through an endoscope, so that the wound is small. Different numbers of magnetic parts are arranged, the closure force of the annular tissue can be adjusted, and treatment personnel can freely select the magnetic parts according to actual conditions, so that the assembly can be suitable for closing function treatment of various annular tissue.

Description

technical field [0001] The invention relates to the technical field of ring tissue treatment components, in particular to a magnetic bead assembly for enhancing the closure function of ring tissue under an endoscope. Background technique [0002] Annular tissues are generally distributed on the walls of certain lumens in humans and animals, and play a vital role in controlling the normal flow of lumen contents. The sphincter is a type of ring-shaped tissue that is found in the digestive tract and urinary system in humans. When the sphincter contracts, it closes the lumen, and when it relaxes, it opens the lumen, and it is usually closed. The lower esophageal sphincter in the gastroesophagus prevents reflux of stomach contents into the esophagus. The pyloric sphincter at the exit of the stomach, which restricts the amount of food expelled with each gastric peristalsis and prevents reflux of duodenal contents into the stomach. The ileocecal sphincter at the junction of the ...

AI Technical Summary

Problems solved by technology

Its disadvantages mainly lie in the need to implant many smaller magnet particles under the endoscope. On the one hand, the magnet particles are small and the magnetic force is small, so it is difficult to achieve a certain attractive force. On the other hand, the number of implanted magnets is large, which is easy shift

[0004] The purpose of the present invention is to provide a magnetic bead assembly for enhancing the closure function of annular tissue under endoscopy, so as to solve the existing technical solutions that are difficult to operate under endoscopy and have relatively large trauma, or the implantation of particles under endoscopy is relatively small At least one of problems such as large number, insufficient magnetic force, easy displacement, poor biocompatibility, or difficulty in applying closed function therapy to various annular tissues
