Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a device capable of being used for isolating and assisting anastomosis of intestinal cavity walls.
Background
With the acceleration of modern life pace and the influence of unhealthy eating habits, the incidence of colorectal cancer is increasing year by year. In all kinds of colorectal anastomosis operations using manual suturing and tube-type anastomat, anastomotic fistula is a common complication, the incidence rate of which is about 2% -20%, the closer the anastomotic stoma is to the anus, the higher the incidence rate of fistula is, especially in low-level rectal cancer operations. After the intestinal tract focus is excised, the intestinal tract broken ends are required to be anastomosed again, if the intestinal tract anastomotic stoma is not healed well, anastomotic fistula appears, intestinal contents can flow into the abdominal cavity, and the abdominal cavity and even the whole body can be infected, so that serious life-threatening disease complications and even death are caused. The anastomotic fistula not only increases the complication and death probability of the patient, but also increases the pain and medical burden of the patient.
Although the conventional manual suture is more suitable for physiological healing of intestinal tracts, the conventional manual suture is time-consuming and labor-consuming. The tubular anastomat is adopted for anastomosis, so that the operation is simplified, but the anastomosis performed by means of the metal titanium nails can cause the metal titanium nails to be permanently reserved at the intestinal wall anastomosis opening.
At present, the conventional clinical practice of preventing anastomotic fistula is to synchronously perform temporary intestinal diversion (diversion) operation during intestinal anastomosis operation, perform stomas on the abdominal wall, carry out bag hanging drainage and perform daily care. After several months, the anastomotic stoma is completely healed and then the intestinal tract recovery operation is performed. Therefore, the life quality of the patient is seriously reduced, the secondary operation of the patient is painful, and the medical burden of each party is increased.
