Liver retractor and component for laparoscopy

Abstract

The invention provides a liver retractor and component for laparoscopy, mainly including hepatic lobe retracting bars, fixing pins for retracting bars, a retractor anchoring clip, an anchor clip take-up bar, guide wires and tightening wrenches, wherein the hepatic lobe retracting bars has a pair, and are respectively located at both sides of the retractor anchoring clip, and fixed pin holes are arranged inside; a retractor connecting hole is arranged on one side, the pull-hook anchoring clip comprises a lower fixing plate and an upper fixing plate, wherein one side of the anchoring clip tightening bar is provided with a threaded hole, the threaded hole is mutually matched with the tightening screw of the lower fixing plate, and the lower fixing plate and the upper fixing plate are tightened and separated by mutual rotating of the threaded hole and the tightening screw of the lower fixing plate. The retractor of the invention has simple structure and is easy to be installed and fixed under the endoscope, so that a satisfactory operation field of vision can be obtained during the laparoscopic operation, and the operation of other surgical instruments is not affected at the same time.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a laparoscopic liver retractor and components. Background technique [0002] Since Kitano et al. reported the first laparoscopic-assisted distal gastrectomy in 1994, laparoscopic techniques have been widely used in gastric cancer surgery. Today, the technology of laparoscopic radical gastrectomy has become more and more mature, and its short-term and long-term curative effect is equivalent to that of open surgery. Most of the domestic tertiary hospitals and some second-level hospitals have carried out laparoscopic radical gastrectomy. [0003] During laparoscopic radical gastrectomy, the left outer lobe of the liver in most patients will block the surgical field of view and interfere with the surgical operation. Therefore, traction, lifting and suspension of the liver are required during the operation. At present, there are two main ways to suspend the liver: 1. The assistant uses...

AI Technical Summary

Problems solved by technology

At present, there are two main ways to suspend the liver: 1. The assistant uses the tip of the surgical instrument to lift or push the liver. When this method is used, the assistant needs to continuously lift the liver, and the assistant is prone to fatigue. At the same time, the surgical instrument is occupied. The tip is easy to damage the liver; 2. Use a suture to bypass the visceral surface of the liver, and the two ends pass through the abdominal wall to pull the liver on the body surface. When this method is used, the pulling needle may not be firmly clamped in the abdominal cavity, and it is easy to stab the abdominal cavity For internal organs and tissues, a single suture has poor traction effect on the liver and cannot well meet the needs of surgery. At the same time, this method requires 2-3 hemlock clips to fix the sutures. The above hemlock clips are discarded after surgery, which causes medical resources waste
