Description

A kind of liver suspension device for laparoscopic surgery

Technical field

The utility model relates to the field of medical instruments, and more specifically, the utility model relates to a liver suspension device for laparoscopic surgery.

Background technique

Laparoscopic surgery is a newly developed minimally invasive method. It makes some holes in the abdominal wall and inserts surgical instruments into the abdominal cavity to perform surgical operations. Laparoscopic surgery has the advantages of minimally invasive, fast recovery, and good surgical field of view. , is an inevitable trend in the development of surgical methods in the future, but laparoscopic surgery also increases the difficulty of surgical operations, because it cannot directly reach into the abdominal cavity with hands to move the organs like traditional surgery, and only relies on a few long rod-shaped surgical instruments. It is inserted into the abdominal cavity for operation, so it is difficult to expose the surgical space. For example, during laparoscopic partial liver resection, in order to facilitate the surgical operation and expand the surgical field of view as much as possible, liver suspension is usually required;

Currently, there is no equipment specifically used for liver suspension. When medical staff perform laparoscopic partial liver resection, they often need to make their own suspension equipment, which is troublesome to operate, has a low safety factor, and can easily endanger the patient's life and health;

Therefore, a liver suspension device for laparoscopic surgery is proposed to solve the above problems.
