Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an intestinal tract anastomosis auxiliary device.
Background
The intestinal anastomosis performed by abdominal surgery is a common surgical procedure, even several intestinal anastomoses are required to be performed in one operation, the most common and mature anastomosis method is the needle and thread suture method, and the traditional needle and thread anastomosis technology is generated from the beginning of 18 th century. The application is well established up to now. Aiming at the tissue and physiological characteristics of various organs, dozens of corresponding suturing methods are developed, so that the surgical technology is developed rapidly, the application of the tube-type anastomat further expands the range of the shell operation, shortens the operation time, reduces the tissue injury and bleeding, and improves the operation safety, but the defects of a plurality of tube-type anastomats are found in clinical practice: the anastomat is a disposable device and is expensive; the operation procedure is complicated and can not be repeatedly operated; the end-to-end anastomosis can not be completed above the rectum, the end-to-side anastomosis needs to be performed by a closer, and the stump forms a blind tube diverticulum after the closure, which is not in line with the physiological structure of the digestive tract; the permanent retention of foreign matters in the body is easy to form larger scars; after the anastomat is anastomosed, the anastomotic orifice still cannot be effectively protected, and the risk of leakage still exists.
Relatively speaking, the needle and thread sewing method is more civilized and mature, however, the needle and thread sewing method anastomosis technology is not perfect, the needle and thread sewing method not only takes longer time, but also has higher operation requirements for an operating doctor, the operating doctor needs to hold the gap between the needle distances of the intermittent sewing, the leakage phenomenon of an anastomotic stoma is prevented, and after the needle and the thread are anastomosed at present, no support inside an intestinal tract is easy to collapse during sewing, the intestinal tract needs to be propped open by an instrument during sewing, then the sewing speed is slowed down, and after the sewing, the intestinal tracts at two ends of the suture stoma are easy to adhere, thereby influencing the postoperative recovery progress.
