Description

Technical Field

[0001] The present invention belongs to the field of gastrointestinal pulling equipment, and in particular relates to a laparoscopic gastrointestinal fixation device for gastrointestinal surgery. Background Art

[0002] Clinical work has found that during gastric tumor resection or radical surgery (exposure of the superior pancreatic region and gastric fundus facilitates clearance of groups 7, 8, 9, and 11 lymph nodes), exposure of the gastric fundus and splenic hilum is often unsatisfactory. Adequate exposure of the splenic hilum facilitates clearance of the left gastroepiploic vessels and surrounding lymph nodes, while repeated adjustments and retraction of the splenic hilar lymph nodes significantly impact surgical progress, safety, and the thoroughness of lymph node dissection. Adequate exposure of the gastric fundus is crucial for bariatric and metabolic surgery, as inadequate exposure can result in insufficient resection and excessive gastric fundus remnants, compromising postoperative weight loss outcomes. During left hemicolectomy or mobilization (the upper jejunum severely impacts exposure of the inferior mesenteric artery root and the left mesocolon), surgical field exposure is often unsatisfactory, requiring repeated retraction and adjustment, increasing the risk of collateral injury and significantly increasing operative time.

[0003] Laparoscopic surgery refers to the use of cold light sources to provide lighting, inserting the laparoscope lens into the abdominal cavity, and using digital camera technology to transmit the images captured by the laparoscope lens through optical fibers to the subsequent signal processing system, and display them in real time on a dedicated monitor. The doctor then analyzes and judges the patient's condition through images of the patient's organs from different angles displayed on the monitor screen, and uses special laparoscopic instruments to perform surgery.

[0004] Existing laparoscopic negative pressure gastrointestinal lifting devices generally use negative pressure suction cups to absorb, lift and fix the gastrointestinal tract. However, the size of the suction cups can easily affect the lifting and fixation effect. Moreover, some more sophisticated negative pressure devices require the use of negative pressure aspirators to generate negative pressure. Although they can more accurately control the negative pressure in the device, since they require supporting facilities to adjust the negative pressure, not only is the use process cumbersome, but it also takes up a large space, making it inconvenient to move back and forth, which brings difficulties to the treatment process.

[0005] In view of this, the present invention is proposed. Summary of the Invention
