[0002] There are several problems with surgical retractors for operating room vacuum suction devices and adjustable operating tables and accessory fixtures during open surgery, especially when it is necessary to retract / shield solid organs and dilated tubular organs.

[0003] At present, metal rigid fixed retractors are commonly used, usually pulled by the second or third assistant, and their effective field of view is usually outside the operating surface, which is prone to iatrogenic injuries caused by poor field of view, sharp contact surface and blunt contusion of the retractor edge.

[0004] Since the edge width of the metal retractor is limited, for active solid organs and peristaltic tubular organs, the peristalsis and sliding of the organs affect the surgical field, and repeated adjustments of the retractor position and angle are required.

[0005] For exposure of a larger operating surface, the traditional method of using saline gauze to fill the physiological cavity and hard wide retractors to pull and expose it, which is currently commonly used in clinical practice, requires the cooperation of experienced surgical operators and more familiar assistants. The learning curve has a great impact on the precision and completion of the operation. Summary of the invention
