Technical Field

The invention relates to the technical field of medical equipment, in particular to a postoperative rectal anastomosis stoma protection device.

Background

Rectal cancer is one of the most common malignant tumors in China, and the incidence rate of the rectal cancer is the third most serious in cities. In recent decades, rectal surgery has made significant progress, and improved surgical techniques have allowed the majority of patients undergoing rectal surgery to retain their sphincters.

At present, the surgical operation method for rectal cancer is to perform rectal anastomosis after positioning and removing a lesion position, and connect the rectum on two sides through an anastomosis. However, the incidence of postoperative anastomotic fistula is always high, the cause of the occurrence of the postoperative anastomotic fistula is related to the distance between the anastomotic stoma and the anus, the blood circulation of the anastomotic stoma, the age of the patient and the basic diseases (diabetes, etc.), and the inevitable fecal contamination of the environment of the anastomotic stoma in the colon and rectum is the main cause of the difficulty in the growth of the anastomotic stoma and the occurrence of the fistula. Anastomotic fistulas, once established, are dangerous and reported to have a mortality rate of 7.5-36% after rectal surgery, the most common cause of death after rectal surgery.

In the prior art, an anastomotic ring is generally adopted to protect an anastomotic stoma, and is fixed at the anastomotic stoma through an inner ring and an outer ring to protect the anastomotic stoma and avoid excrement pollution. However, the operation of the anastomosis ring in the operation is very complicated, the ring body needs to be fixed in the intestinal cavity, the protection effect of the anastomosis ring is poor, and the anastomosis ring polluted by excrement still has the risk of infecting the anastomosis opening; in addition, when the anastomotic ring is used for protection, the condition inside the intestinal cavity is difficult to observe through X-rays, and the leakage condition of the intestinal cavity cannot be monitored regularly by a patient, so that the anastomotic fistula condition cannot be treated in time.

Therefore, it is necessary to develop a new anastomotic stoma protector.
