Abstract
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
The invention belongs to technical field of medical instruments, relate to degradable magnesium alloy medical apparatus and instruments, especially relate to a kind of degradable magnesium alloy Surgical healing method and device.
Background technology
Intestinal anastomosis is that gastrointestinal surgery rebuilds gastrointestinal important technology, and desirable intestinal anastomosis not only requires anastomotic stoma secure, also requires that easy and simple to handle, foreign of trying one's best remains.Anastomosis ring is mainly used in the diseases such as intestinal tumor, colon tumor, intestinal obstruction, intestinal wound, intestinal perforation, colon cancer.
The method that bowel anastomosis more often adopts is Anastomat hemorrhoidal circumcision, after using anastomat, there will be the situations such as bowel narrow.And the anastomosis staple that anastomat uses is titanium alloy, permanently stays in the body, this inevitably creates negative effect, through the long mechanical wear of intestinal, generate metal ion or the granule of bio-toxicity, surrounding tissue allergy or inflammatory reaction can be caused, reduce the biocompatibility of material.
Summary of the invention
The object of the present invention is to provide a kind of degradable magnesium alloy bowel anastomosis ring, for promoting surgical quality.
Degradable magnesium alloy bowel anastomosis ring of the present invention, comprises ring body, and ring body is that magnesium alloy is divided into two, mutually corresponding setting; Ring body is provided with many pins and hole, position, the quantity in the position of pin on a ring body, quantity and hole on another ring body are corresponding.
Ring body hollow, diameter and intestinal diameter match.
Described pin and the quantity in hole are 6.
The present invention compared with prior art, has following beneficial effect:
The present invention realizes Sutureless and coincide, and foreign remains, and inflammatory reaction is light; Match result is reliable, safety, and because its tissue injury is few, blood supplies, and the contents such as anastomotic stoma and enteral feces, antibacterial separate completely, and have the impermeabilisation of high strength, ability is split in antiknock, effectively prevents anastomotic leakage; The cradling function of identical ring body, both ensure that enteric cavity was unobstructed, intestinal function early recovery, again the generation of effective preventing anastomotic stricture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, ring body; 2, pin; 3, intestinal.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated:
Degradable magnesium alloy bowel anastomosis ring as shown in Figure 1, comprises ring body 1, and ring body 1 is divided into two for magnesium alloy, mutually correspondingly arranges; Ring body 1 is provided with 6 pins and 6 holes, position, the quantity in the position of pin on a ring body, quantity and hole on another ring body are corresponding.
Ring body 1 hollow, diameter and intestinal 3 diameter match.
During connection, intestinal 3 turns up through ring body 1, and fix with 6 pins, opposite side intestinal equally so operates, more mutually embeds involutory by the pin of two ring bodies, hole.This bowel anastomosis method is simple, and speed of coincideing is fast, is about 2-5 minute and just intestinal can be connected, and can one man operation.This method is coincide after intestinal, due to the existence of anastomosis ring, provides a kind of supporting role, prevents the flat wrinkle of intestinal, effectively prevents the blocking of intestinal.And anastomosis ring is degradable magnesium alloy material, can vivo degradation again, without any side effects.
Magnesium alloy, as a kind of novel bio-medical material, has the features such as good biocompatibility and degradability, has received increasing concern.Magnesium ion is the second important cation in human body cell, harmless.In addition, magnesium also has multiple special physiological function, and it can swash in vivo multiple enzyme, suppresses dysautonomia excited, maintains the stable of nucleic acid structure, participates in the synthesis of body internal protein, muscle contraction and thermoregulation etc.
The anastomosis ring that degradable magnesium alloy material makes, has supporting role to intestinal, prevents because cause stenosis of bowel to cause the problems such as intestinal obstruction after using anastomat; Degradable magnesium alloy is after intestinal healing, and disappearance of automatically degrading, avoids the long-term existence of human body foreign body, reduces the generation of various untoward reaction.
Claims (3)
1. a degradable magnesium alloy bowel anastomosis ring, is characterized in that, comprises ring body, and ring body is that magnesium alloy is divided into two, mutually corresponding setting; Ring body is provided with many pins and hole, position, the quantity in the position of pin on a ring body, quantity and hole on another ring body are corresponding.
2. degradable magnesium alloy bowel anastomosis ring according to claim 1, is characterized in that, ring body hollow, and diameter and intestinal diameter match.
3. degradable magnesium alloy bowel anastomosis ring according to claim 1, is characterized in that, described pin and the quantity in hole are 6.
