Device and method for preventing anastomotic fistula after colorectal surgery

Abstract

The invention discloses a method for preventing anastomotic fistula after colorectal surgery. The method comprises the following steps of: step 1, performing preoperative preparation, cutting off a colorectal lesion part, and suturing an anastomotic stoma; step 2, mounting a supporting protective net to protect the anastomotic stoma; step 3, guiding a fixed part at the head end of a catheter from anumbral tract to a ileocecal flap, inflating the fixed part to enable the fixed part to be clamped at the ileocecal flap, enabling the position of the catheter and the position of the ileocecal flap to be relatively fixed through the fixed part, performing double blocking on the intestinal tract, and meanwhile, guiding out intestinal contents through the catheter; and step 4, after the anastomotic stoma of a patient is healed, exhausting the catheter, and withdrawing the catheter and the fixed part from the ileocecal flap through the anus. The method can prevent the anastomotic fistula, is beneficial to wound healing of the patient, only needs to perform surgical suturing on the anastomotic stoma, does not need to perform surgical opening and suturing on other parts, reduces body trauma brought to the patient by surgery, is beneficial to improving the postoperative life quality of the patient, and is suitable for the technical field of medical instruments.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device and method for preventing anastomotic leakage after colorectal surgery. Background technique [0002] Colorectal cancer (carcinoma of colon and rectum) is a common malignant tumor in the gastrointestinal tract. The early symptoms are not obvious. As the cancer grows larger, it shows symptoms such as changes in bowel habits, blood in the stool, diarrhea, alternating diarrhea and constipation, and local abdominal pain. In the late stage, systemic symptoms such as anemia and weight loss are manifested. Its morbidity and mortality are second only to gastric cancer, esophageal cancer and primary liver cancer among digestive system malignant tumors. Surgical resection is the most effective treatment option for colorectal cancer. However, anastomotic leakage is a common clinical complication. In the early stage, the incidence of anastomotic leakage in Chin...

Problems solved by technology

It uses a balloon to position the catheter through a balloon and a threaded tablet, and the other balloon to block the intestinal content and discharge it through the catheter. On the one hand, surgery needs to be performed on the abdomen, causing unnecessary trauma to the patient. On the other hand, single balloons are less effective at blocking intestinal contents
