Novel degradable supporter for intestinal canal anastomosis surgery

Abstract

The invention provides a degradable supporter for intestinal canal anastomosis surgery, wherein hollow starch expanded material is used as the main body of the supporter and the expanded material is filled with antibiotic medicine and analgesic, the supporter is prepared by sealing the supporter main body with bone wax. A series of scientific component experiments is carried out through shaping the starch expanded material, integrating multiple medicaments and preparing the external protection layer so that the supporter is provided with features such as supporting, drug therapy and timing degradation, providing proper and effective forms and structures for animal intestinal canal anastomosis surgery; acting points are well grasped by means of the supporting effect provided by the supporter so as to increase stitching speed, shorten the total time consumption for surgery, reduce the difficulty of the surgery and reduce the chances of anastomotic fistula; by means of the supporter, the contraction degree of intestinal canal muscular layer can be obviously decreased and the occurrence rate of anastomotic stenosis is reduced; the degradable feature of the supporter can play the role of post operative analgesia, hemostasis and antiphlogosis, and finally avoid and reduce the occurrence of postoperative complications, which is helpful for the recovery of animal physiological functions.

Description

technical field [0001] The invention relates to the technical field of surgical tools, and more specifically, to a novel degradable support used in intestinal anastomosis. Background technique [0002] Intestinal anastomosis is an important surgical operation for animal clinical treatment of intestinal wall necrosis, perforation and rupture, such as intestinal wall necrosis caused by intestinal foreign body obstruction or intussusception, traumatic intestinal adhesion or intestinal fistula, intestinal wall tumors, etc., all need to be resected Diseased intestinal segment and implementation of intestinal anastomosis. Throughout the history of the development of gastrointestinal surgery, the method of anastomosis is the key to the reconstruction of the gastrointestinal tract, and it is also the key to restricting the further development of gastrointestinal surgery. The so-called appropriate anastomosis method requires simple operation, easy learning, reliable anastomosis, and ...

AI Technical Summary

Problems solved by technology

At present, there are many methods of digestive tract anastomosis, such as manual suture, stapler anastomosis, laser welding, adhesive anastomosis, etc.; traditional intestinal end-to-end anastomosis is mostly performed after partial resection of the necrotic intestinal tract, and aligning the healthy intestinal tract with surgical silk or catgut. Double-layer suture, cumbersome operation, easy to cause intestinal stenosis in puppies with thin intestinal tubes

Due to the empty intestinal cavity, the intestinal wall is close together, suturing is difficult, and the anastomotic effect is not good. After the operation, it is easy to cause leakage of intestinal contents or intestinal stenosis, and even lead to the failure of the operation

And if the suturing time is too long, the serosa layer of the intestinal wall will suffer more mechanical stimulation, and adhesions will easily occur, which is not conducive to the recovery of digestive function after surgery.

[0003] In the medical field, degradable one-piece intestinal anastomosis aids and intestinal anastomosis stents have been developed, but these devices are too large in diameter for small animals and expensive, and are not suitable for small animal intestinal anastomosis operations
