Problems solved by technology
In addition, the staples used in the stapler are titanium alloys, which are permanently left in the body, which inevitably produces negative effects. After a long period of mechanical wear in the intestinal tract, biotoxic metal ions or particles are generated, which can cause allergies or Inflammatory response, which reduces the biocompatibility of the material

Embodiment Construction
[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0013] Such as figure 1 The degradable magnesium alloy intestinal 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 one ring body is provided with 6 needles and 6 holes. The positions and quantities of the needles 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 intestinal tract 3 .
[0015] When connecting, the intestinal tract 3 passes through the ring body 1 and turns outward, and is fixed with 6 needles. The same operation is done for the intestinal tract on the other side, and then the needles and holes of the two ring bodies are inserted into each other. The intestinal anastomosis method is simple ...

The invention discloses a degradable magnesium alloy intestinal anastomosis ring. The degradable magnesium alloy intestinal anastomosis ring is characterized by comprising ring bodies, wherein the ring bodies are made of aluminum alloy, the number of the ring bodies is two, and the two ring bodies are mutually and correspondingly arranged; the ring bodies are provided with multiple needles, and multiple holes are formed in the ring bodies; the positions and the number of the needles on one ring body correspond to the positions and the number of the holes in the other ring body. According to the degradable magnesium alloy intestinal anastomosis ring disclosed by the invention, sutureless anastomosis is realized, no foreign residuals exist, and an inflammatory reaction is mild; an anastomosis effect is reliable and safe, an anastomotic stoma is completely separated from contents of faeces, bacteria and the like in the intestine because the degradable magnesium alloy intestinal anastomosis ring is less in tissue damage and good in blood supply, high-strength osmotic resistance and high-strength anti-burst performance are obtained, and anastomotic leakage can be effectively prevented; because of a support function of the anastomosis ring bodies, enterocoel smoothness and intestine function early recovery are ensured, and anastomotic stenosis is also effectively prevented from happening.
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 the gastrointestinal tract in gastrointestinal surgery. An ideal intestinal anastomosis not only requires a firm and safe anastomosis, but also requires easy operation and no foreign matter residue 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 of intestinal anastomosis is stapler anastomosis. After using a stapler, intestinal strictures and other conditions may occur. In addition, the staples used in the stapler are titanium alloys, which are permanently left ...
