With the development of laparoscopic devices and techniques, laparoscopic minimally invasive surgery has been widely used in abdominal surgery. Laparoscopic surgery offers a number of advantages over traditional open surgery. The laparoscopic surgery can be observed from multiple angles, and the effect is intuitive. The wound of the patient is far less than that of an open abdomen operation, the postoperative recovery is quick, the patient is easy and has less pain, and the hospitalization time is short. The trocar hole of the abdominal wall is small, and the beauty effect is good after healing. The operation mainly comprises electrosection and electrocoagulation, the bleeding is less, the flushing is thorough before the operation is finished, the postoperative intestinal function is recovered quickly, and the complications such as postoperative intestinal adhesion are reduced. In short, laparoscopic surgery has the characteristics of minimal invasion, safety, aesthetic property and the like, and is developed rapidly in recent years.
In laparoscopic surgery for rectal cancer, the assistant needs to pull the intestinal canal to help the main knife complete rectal dissection and make the cutting stapler easier to clamp to the optimal tissue cutting suture position. If a patient with an obese body or a patient with a relatively insufficient pelvic cavity space is encountered, the area of the laparoscopic grasper contacting the intestinal canal is small, and the assistant worrys about the injury of the intestinal canal pair caused by excessive force, so that the laparoscopic grasper has poor traction effect and insufficient visual field exposure.
In the prior art, chinese utility model patent document No. CN202681999U discloses an intestinal canal retractor for surgical operation, which is used for pulling intestinal canal by retractor blades to cause poor stability, easy slippage and easy damage to the intestinal canal.
