Description

Technical Field

[0001] The present 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 body: the colon and the rectum. The colon is part of the large intestine and includes the ascending colon, transverse colon, descending colon, and sigmoid colon, which together surround the abdomen and have the function of absorbing water and promoting bowel movements. The rectum is located in the lower part of the pelvis 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 is higher in men than in women.

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

[0004] After searching, the Chinese patent with application number "CN201822166711.2" is specifically a traction device for connecting to the anastomosis device during colorectal surgery. The traction device for connecting to the anastomosis device during colorectal surgery is installed by installing the needle from the lower end opening of the mounting tube, and the puncture part of the needle extends from the opening at the upper end of the mounting tube. At the same time, the baffle and the block are used in conjunction to install the needle in the connecting cavity through the mounting tube for position fixing. By increasing the number of pads, the length of the 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 through the puncture part, and then the needle is rotated and trimmed through the first trimming part and the second trimming part, which is beneficial to reduce tearing when the end of the anastomosis device 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. A traction and fixation device is required to limit the colorectum to ensure a clear laparoscopic view and provide sufficient tension to facilitate separation and operation of anatomical planes. In the prior art, a needle is used to puncture the posterior wall of the rectum, and a shaping block is used to shape the puncture wound to reduce surgical pain. However, no limitation is performed on the outside of the needle during surgery, resulting in a low stability of the needle. During surgery, the needle is easily deviated, causing increased damage to the patient's puncture site. Summary of the Invention

Under the action of the control board 1 605, the multiple stable branch plates 602 are controlled to rotate and tilt, so that the stable plate 622 of the stable box 615 on the stable branch plate 602 rotates and tilts, so that the stable plate 622 contacts the posterior wall of the colorectum, which is convenient for limiting the needle 5. At the same time, when the lifting ring 607 rises, the moving rod 612 and the lifting ring 607 are moved. Under the action of the piston ring 611, the air in the air cylinder 610 is discharged, and under the action of multiple branch hoses 613, the gas is passed into the rectangular groove 616. Under the action of the piston plate 618 and the connecting rod 619, the stabilization box 615 and the stabilization plate 622 are raised, so that the stabilization plate 622 is in closer contact with the inner wall, thereby increasing the limiting effect.
