Description

technical field [0001] The invention relates to a medical device, in particular to a traction device for hepatobiliary surgery. Background technique [0002] Hepatobiliary Surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of Chinese people. Hepatobiliary diseases are also diseases that we have seen for a long time in our lives. The clinical treatment of such diseases is often achieved through laparoscopic surgery. [0003] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open opera...

Problems solved by technology

[0005] Nowadays, laparoscopic surgery is generally used in hepatobiliary surgery, and many hepatobiliary surgery requires laparotomy. At this time, it is necessary to manually use different instruments to pull apart the abdominal cavity and liver and gallbladder viscera. Manual operation is more difficult. At the same time, it is difficult to maintain a fixed state for a long time, which cannot meet the current use requirements
