Description

Endoscope fixing device Technical Field The utility model relates to the technical field of medical instruments, in particular to an endoscope fixing device. Background In minimally invasive spinal surgery, endoscopes are often used to assist medical personnel in viewing the affected area. After the endoscope viewing position is determined during the operation, the endoscope needs to be stabilized at the viewing position. The traditional endoscope stabilization mode needs medical staff to hold the endoscope in the same posture for a long time, and the holding process needs to be highly concentrated, so that the medical staff is easy to suffer from muscle strain and fatigue, the operation safety is affected, and the endoscope is inconvenient to stably use in the operation. In order to relieve manpower and ensure stable use of the endoscope in operation, an endoscope supporting frame is generally adopted at present to stabilize the endoscope, and the endoscope supporting frame can realize adjustment of the position and the angle of the endoscope. The endoscope supporting frame needs to be connected with the endoscope through a fixing structure, and the problems of unstable clamping and complex operation exist in some existing fixing structures. If the jackscrew type fixing device and the magnetic attraction type fixing device are used, when the jackscrew type fixing device is installed, the jackscrew type fixing device needs to be sleeved on the lens end of the endoscope and then is used for propping up against the endoscope to fix, when the endoscope needs to be separated from the supporting frame, the endoscope needs to be taken out of a patient, the complicated degree of operation is increased, the jackscrew fixing device is not only easy to damage the endoscope, but also small in fixing area and poor in stability, the magnetic attraction type fixing device is used for adsorbing and fixing the endoscope by means of magnetic force, magnetic components can reduce magnetism due to the influence of external factors such as high temperature, strong magnetic field and the like, and the clamping stability is low.
