Problems solved by technology

In addition, the staples used in the stapler are titanium alloys, which are permanently left in the body, which inevitably has a negative impact. After long-term mechanical wear of blood vessels, biotoxic metal ions or particles are generated, which can cause allergies or inflammation in surrounding tissues. reaction, reducing the biocompatibility of the material

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] like figure 1 The degradable magnesium alloy vascular anastomosis ring shown includes a ring body 1, which is divided into two magnesium alloy rings, which are arranged corresponding to each other; the ring body 1 is provided with 6 needles and 6 holes, and the needles on one ring body The positions and quantities of the holes correspond to the positions and quantities of the holes on the other ring body.

[0014] The ring body 1 is hollow, and its diameter matches that of the blood vessel 3 .

[0015] When connecting, the blood vessel 3 passes through the ring body 1 and is turned outward, and is fixed with 6 needles. The same operation is done for the blood vessel on the other side, and then the needles and holes of the two ring bodies are inserted into each other. The blood vessel anastomosis method is simple and fast, and the blood vessels can be...

Abstract

The invention discloses a degradable magnesium alloy vascular anastomosis ring. The degradable magnesium alloy vascular anastomosis ring is characterized by comprising two ring bodies made of magnesium alloy, wherein the two ring bodies are arranged corresponding to each other; multiple needles are arranged on one ring body, multiple holes are formed in the other ring body, and the position and number of the needles on one ring body correspond to the position and number of the holes in the other ring body. Through the degradable magnesium alloy vascular anastomosis ring, suture-free anastomosis is achieved, no foreign matter is left, and inflammatory reactions are light; the anastomotic effect is reliable and safe; since tissue damage is less, blood supply is good, an anastomotic stoma is completely isolated from excrement, bacteria and other contents in intestines, and high-strength permeation resistance and burst resistance are achieved, anastomotic leakage is effectively prevented; due to the support function of the ring bodies, it is ensured that the enteric cavity is smooth and intestine functions restore early, and a narrow anastomotic stoma is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a degradable magnesium alloy medical device, in particular to a degradable magnesium alloy intestinal anastomosis method and device. Background technique [0002] Intestinal anastomosis is an important technique for reconstructing gastric vessels in gastrointestinal surgery. An ideal intestinal anastomosis not only requires a firm and safe anastomosis, but also requires easy operation and no foreign body residues as much as possible. Anastomotic rings are mainly used in small intestinal tumors, colon tumors, intestinal obstruction, intestinal trauma, intestinal perforation, colon cancer and other diseases. [0003] The most commonly used method for vascular anastomosis is stapler anastomosis. After using a stapler, conditions such as vascular stenosis may occur. In addition, the staples used in the stapler are titanium alloys, which are permanently left in the body, which ...
