Embodiment Construction

[0016] like figure 1 As shown, the magnetic compression anastomotic ring includes a pair of magnetic rings respectively accommodated in the ends of the two tissues to be anastomotic. For the convenience of expression, they are respectively called magnetic ring Ⅰ 1 and magnetic ring Ⅱ 2. Clamp the free edges of the stump ends of the two anastomotic tissues.

[0017] Since the inner diameter of the anastomotic intestinal cavity is determined by the outer diameter of the anastomotic ring during magnetic anastomosis, the magnetic ring can achieve a larger and smoother anastomosis. In order to adapt to different anastomotic intestinal lumens, the outer diameters of the selected magnetic rings are 29mm, 26mm, and 24mm. , respectively suitable for anastomosis of the colon, lower colorectum, gastrointestinal tract, and small intestine.

[0018] On the premise of ensuring the strength of the magnetic ring, the weight of the magnetic ring is made as light as possible. The radial thick...

Abstract

The invention provides a magnetic force compressing anastomosis ring, comprising a pair of magnetic rings respectively accommodated in the fractured ends of two tissues to be anastomosed, wherein the two magnetic rings are sucked to tightly clamp the free margins of the fractured ends of the two tissues to be anastomosed. The two magnetic rings of the magnetic force compressing anastomosis ring are respectively placed in the fractured ends of the stomach (intestine), and pressure is tightly applied to the two fractured ends to realize anastomosis under the action of magnetic force, so that occlusion tissues are gradually necrotic because of ischemia, meanwhile, occlusion tissues at fractured ends of the stomach (intestine) gradually heal up through an inflammatory reparative process. Along with the gradual necrosis of the occlusion tissues, the two rings are close to each other gradually, and the magnetic force is further enhanced, so that tight anastomosis is maintained, and the necrosis of the occlusion tissues is sped up. The anastomosis is firm and tight, the operation is simple, the healing process is quick, scars are small, surfaces of wound are smooth, and the gastrointestinal cavity is unobstructed. The anastomosis ring can effectively reduce complications after anastomosis operation such as anastomosis leakage, stenosis and the like, and can guarantee good alimentary tract function after operation, thus being the most advanced alimentary tract anastomosis machinery at present.

Description

technical field [0001] The invention relates to the field of gastrointestinal anastomosis and intestinal anastomosis, in particular to a magnetic compression anastomosis ring applied to end-to-end, end-to-side or side-to-side anastomosis of the gastrointestinal tract and end-to-end, end-to-side or side-to-side anastomosis of the intestine. Background technique [0002] The application of the stapler is a great leap forward in surgery. It makes the anastomosis operation simple, shortens the operation time, and enables some complicated operations to be carried out smoothly. In the 1840s, the Institute of Experimental Surgical Instruments of the former Soviet Union conducted systematic research on staplers and was at the leading level in this field. In 1958, American scholar Ravitch introduced the stapler technology to the United States. Ethicon Corporation of the United States produced the first disposable stapler in 1979, which brought the mass production and wide applicatio...
