Background
The rectum is the last segment of the intestine, which is connected above the sigmoid colon and below the anus. Rectal cancer refers to cancer from the dentate line to the rectosigmoid junction, and is one of the most common malignancies of the digestive tract. The location of rectal cancer is low. But the position of the pelvic cavity is deep, so the anatomical relationship is complex, the operation is not easy to be thorough, and the postoperative recurrence rate is high. Meanwhile, the middle and lower rectal cancers are close to the anal sphincter, and medical staff needs to cut the rectum and the anus of the patient together during the operation.
Currently, when using an enterotomy, such as a rectum, medical staff can perform the operation laparoscopically through an open procedure or using a double anastomosis technique. After the operation, the resected section of the patient's bowel starts at the cutting site and the cut bowel is pulled out of the anus. However, the intestinal wall has elasticity, and the length of the cutter of the existing cutting device cannot be adjusted, and when the cutter is used for cutting the intestinal tract of a patient, a gap exists between the cutter and the intestinal wall of the patient, so that medical staff cannot cut the intestinal tract of the patient.
