technical field

The invention relates to the technical field of medical devices, in particular to a hook device used in robot-assisted laparoscopic surgery.

Background technique

Bladder and prostatectomy are important urological procedures for the treatment of many bladder and prostate diseases. However, the anatomical positions of the prostate and bladder are located deep in the human body, and the surgical area should not be exposed during the operation, which makes the operation difficult and increases the risk of the operation.

At present, with the development of laparoscopic minimally invasive surgery and the maturity of today's robotic surgery system, surgical problems that were difficult to solve in the past have all been solved. In the visually magnified surgical field of view, minimally invasive and precise surgical effects are achieved through various operating instruments.

However, during the operation, adequate exposure of the surgical area is still the top priority. Conventional laparoscopic surgery and robotic surgery systems expose some surgical areas of the prostate and bladder with the help of surgical forceps and assistants. However, in obese patients, In patients with other conditions such as adhesions in the surgical field, it is still sometimes difficult to expose the surgical field of the prostate and bladder. At present, there is no report and clinical application of relevant retractor devices in clinical operations.
