Embodiment Construction

[0052] A mother-in-command surgical anastomosis magnetic ring of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.

[0053] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a mother-in-child surgical anastomosis magnetic ring of the present invention includes a sub-ring 1 and a main ring 2, and the sub-ring 1 and the main ring 2 are both oval or circular ring structures, and the sub-ring 1 and the female ring 2 are connected and positioned with each other through more than two buckle structures 3 provided on the female ring 2. The female ring 2 is formed with an intermittent groove on the annulus 5 that is in contact with the sub-ring 1 6. A pressing slope 7 is formed on the outer periphery of the ring surface 5 .

[0054] The thickness of the female ring 2 is 1-10 mm. By setting the female rings 2 with different thicknesses, one sub-ring 1 can be equipped with a series of fem...

Abstract

The invention discloses a primary-secondary type surgical anastomosis magnetic ring. Both the secondary ring and primary ring are elliptic or round rings, the secondary ring and primary ring are mutually connected and located through more than two buckle structures on the primary ring, discontinuous grooves are formed in the ring surface of the primary ring in contact with the secondary ring, and a press incline is formed on the periphery of the ring surface. The primary ring comprises an elliptic or round primary ring sleeve and an elliptic or round primary magnetic ring corresponding to the primary ring sleeve and made of magnetic material, the primary ring sleeve is annular U groove-shaped, the primary magnetic ring is embedded in the annular U groove structure, and the discontinuous grooves, press incline and buckle structure are formed in the corresponding sleeve surface of the primary ring sleeve. The secondary ring comprises an elliptic or round secondary ring sleeve and an elliptic or round secondary magnetic ring corresponding to the secondary ring sleeve and made of magnetic material, the secondary ring sleeve is annular U groove-shaped, and the secondary magnetic ring is inserted in the annular U groove structure. The primary-secondary type surgical anastomosis magnetic ring is capable of preventing the untimely magnetic ring falling due to quick magnetic force increase due to tissue healing thinning between magnetic rings and preventing the staggering of the secondary ring and primary ring.

Description

technical field [0001] The invention relates to a surgical anastomosis magnetic ring used for hemorrhoid circumcision, colorectal anastomosis or circumcision. In particular, it relates to a mother-child surgical anastomosis magnetic ring with a composite structure. Background technique [0002] The principle of magnetic ring pressing and matching 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; use the same shape of magnetic rings to automatically align in three-dimensional space The characteristics of the magnetic rings are precisely aligned, resulting in ischemic necrosis of the intestinal wall compressed between the magnetic rings, and at the same time, the adjacent intestinal walls outside the magnetic rings are gradually healed. In 1978, former Soviet Union Kanshin et al. used magnetic rings for the first gastroduodeno-jejunum side-t...
