[0002] During the operation, in order to facilitate medical staff to quickly observe the diseased tissue in the patient's chest and reduce the patient's trauma, medical staff usually use a thoracoscope. In order to improve the stability of the operation during the use of the thoracoscope, medical staff usually use a thoracoscope fixing device to firmly fix the thoracoscope in the operation area. The existing thoracoscope fixing device usually consists of a base, a fixing block, a support frame and a clamping block.

[0003] For example: the invention patent with application number CN202010347365.7 discloses a thoracoscopic device for minimally invasive surgery of esophageal cancer, which specifically includes a bottom support frame, the bottom of which is fixedly connected with a flexible rubber pad, the side of which is movably installed with a side pressure plate, the bottom support frame and the side pressure plate are movably connected through a pressure stop seat, and the inner side of the side pressure plate is movably installed with an arc splint. The thoracoscopic device for minimally invasive surgery of esophageal cancer, by setting the cooperation of the pressure stop seat, the side pressure plate and the arc splint, makes it easier to better fix the device on the surface of the human body when fixing the thoracoscope, and by setting the cooperation of the jamming knob, the rotating seat, the support frame, the support slide bar and the transverse bracket, the support device can fix the thoracoscopic tube in different forms, so that the thoracoscope will not be affected by other surgical instruments after being fixed.
