Description

Technical Field

[0001] The invention relates to the technical field of colorectal microsurgery, in particular to a colorectal traction and fixation device for gastrointestinal surgery. Background Art

[0002] The colorectum refers to the two parts of the colon and the rectum. The colon is part of the large intestine, including the ascending colon, transverse colon, descending colon and sigmoid colon, which together surround the abdomen and have the function of absorbing water and promoting defecation. The rectum is located in the lower part of the pelvic cavity and is the end of the digestive tract. Its main function is to store stool and absorb the water in it. Colorectal cancer is a malignant tumor of the digestive tract that occurs at the junction of the rectum and the sigmoid colon. It is usually more common in middle-aged and elderly people over 40 years old, and the incidence rate in men is higher than that in women.

[0003] Minimally invasive colorectal surgery is a modern surgical technique that uses small incisions or natural orifices to enter the body for surgery, aiming to reduce surgical trauma and bleeding, while shortening recovery time and relieving postoperative pain. This surgical method mainly includes laparoscopic surgery and robot-assisted surgery.

[0004] After searching, the Chinese patent with application number "CN201822166711.2" is specifically a traction device connected to the stapler in colorectal surgery. The traction device connected to the stapler in colorectal surgery is installed by installing the puncture needle from the lower end opening of the mounting tube, and the puncture part of the puncture needle extends from the upper end opening of the mounting tube. At the same time, through the cooperation of the baffle and the block, the puncture needle is installed in the connecting cavity through the mounting tube for limit fixation. By increasing the number of pads, the length of the puncture needle extending out of the mounting tube can be adjusted to meet different length requirements and improve the fastening effect. The posterior wall of the colorectum is punctured by the puncture part, and then the puncture needle is rotated and trimmed by the first trimming part and the second trimming part, which is beneficial to reduce tearing when the end of the stapler passes through the hole, thereby improving the safety of the operation.

[0005] During minimally invasive surgery, a laparoscope is used to provide a clear view of the abdominal cavity, allowing surgeons to perform precise operations without opening the abdominal cavity. The colorectum needs to be limited by a traction fixation device to ensure a clear laparoscopic field of view and provide sufficient tension to facilitate separation and operation of anatomical planes. In the prior art, the posterior wall of the rectum is punctured by a needle, and the puncture wound is reshaped by a shaping block to reduce surgical pain. However, the outer side of the needle is not limited during the operation, so that the stability of the needle is not high. During the operation, the needle is easily offset, which increases the damage to the patient's puncture position. Summary of the invention
