A kind of mother-in-law surgical anastomosis magnetic ring

Abstract

A sub-female surgical anastomosis magnetic ring, the sub-ring and the mother ring are oval or circular ring structures, the sub-ring and the mother ring are connected and positioned by more than two buckle structures arranged on the mother ring, A discontinuous groove is formed on the ring surface of the mother ring in contact with the sub-ring, and a pressing slope is formed on the outer periphery of the ring surface. The female ring has an oval or circular female ring sleeve and an oval or circular female magnetic ring made of magnetic material corresponding to the female ring sleeve. The female ring sleeve is a ring U-groove structure, and the female magnetic ring is embedded in the ring In the U-groove structure, the discontinuous groove, the pressing slope and the buckle structure are all formed on the corresponding sleeve surface of the female ring sleeve. The sub-ring has an elliptical or circular sub-ring sleeve and an oval or circular sub-magnetic ring made of magnetic material corresponding to the sub-ring sleeve. The sub-ring sleeve is an annular U-groove structure, and the sub-magnetic ring is embedded in the ring Inside the U-groove structure. The invention can prevent the magnetic force from becoming thinner as the tissue between the magnetic rings heals, and the magnetic rings will fall off prematurely due to the rapid increase of the magnetic force, and prevent the misalignment of the sub-rings and the main rings.

Description

Technical field [0001] The invention relates to a surgical anastomosing magnetic ring used for hemorrhoid circumcision, colorectal anastomosis or circumcision. In particular, it relates to a child-mother-type surgical anastomosis magnetic ring with a composite structure. Background technique [0002] The principle of magnetic ring pressing and anastomosis is to use the strong attraction between the magnetic rings made of rare-earth permanent magnets to produce continuous, non-penetrating, and gradually strengthened mechanical compression; using the same shape of magnetic rings to automatically join in three-dimensional space The precise alignment of the characteristics of the magnetic ring leads to avascular necrosis of the intestinal wall under pressure between the magnetic rings, and the adjacent intestinal wall outside the magnetic ring gradually heals. In 1978, the Soviet Union Kanshin and other scholars used the magnetic ring to perform gastroduodenal-jejunal side-to-side a...

Problems solved by technology

[0006] The patent No. 201210000963.2 relies on the deformation of the magnetic ring to pass through the colorectal cavity and anus smoothly. Since the excised part of the mucosa on the hemorrhoid is close to the dentate line, this patent decomposes the complete magnetic ring into 4 parts and joints for easy discharge from the human body. connection, it is easy to cause complicated manufacturing process, weaken magnetic force and increase instability
