Technical Field
The invention relates to the technical field of medical instruments, in particular to an intestinal anastomosis stoma isolation device.
Background
Anastomotic leakage is one of the serious complications in gastrointestinal surgery. Because anastomotic leakage occurs, the hospitalization time is prolonged for mild patients and the treatment cost is increased, and peritoneal infection is caused for severe patients and even the patients are life-threatening.
Therefore, a series of technical specifications and measures have been developed clinically for preventing anastomotic leakage and avoiding complications caused by anastomotic leakage. In addition to enhancing the surgical technique and the strict specification of the quality and operation of the instruments, the most clinically important measure is the use of a protective stoma of the terminal ileum, which avoids complications due to anastomotic leakage. Particularly, in the operations of rectal cancer, low rectal cancer, sigmoid colon and left half colon, the incidence rate of anastomotic leakage is higher, and the ratio of ileostomy is higher.
Although the ileal protective stoma solves the risk caused by stoma leakage, the patient needs to undergo a stoma hanging bag for more than 3 months and a secondary stoma recovery operation, which greatly increases the pain and treatment cost of the patient.
Therefore, clinically, a device which can prevent complications caused by anastomotic leakage and avoid the ileum protective stoma is urgently needed.
