[0001] The present invention relates to the technical field of medical microscopes, in particular to a medical microscope system and a use method thereof. Background Art

[0002] In recent years, minimally invasive surgery, represented by surgical microscope technology, has developed rapidly. The combination of minimally invasive surgery and robotic technology can overcome the shortcomings of traditional minimally invasive surgery, such as limited observation and range of motion, lack of visual feedback, and easy fatigue of doctors, and provide a precise and stable operating environment suitable for ergonomics, improving the accuracy and safety of surgery. The cantilever of the surgical microscope frame is mainly used to support the microscope and provide the function of moving the microscope up, down, left, and right during the operation.

[0003] The Chinese patent document with the existing announcement number CN102940532A discloses a surgical microscope frame, which improves and optimizes the problems that the cantilever of the surgical microscope frame has a large swing amplitude, which is easy to hit the doctor or other objects, which is not conducive to maintaining a sterile surgical environment; and the cantilever has a complex structure, is inconvenient to use and has poor balance; that is, it forms a gravity-balanced and mechanical spring-balanced compatible cantilever through a first parallelogram, a second parallelogram, a third parallelogram, a fourth parallelogram, an elastic member, a regulating valve and a balance bar. The gravity-balanced and mechanical spring-balanced compatible cantilever has a simple structure, a small swing amplitude, will not hit the doctor or other objects, is conducive to maintaining a sterile surgical environment, and can adjust the microscope at multiple angles and ranges, is flexible to use and has good balance, and is particularly suitable for mid-to-high-end surgical microscopes. In addition, the elastic member, the regulating valve and the balance rod constitute a balance auxiliary mechanism, and the balance auxiliary mechanism is used to adjust the internal force of the diagonal part of the second parallelepiped linkage. Different surgical microscopes have different weights. When the surgical microscope is installed on the fixed part, the user can adjust the regulating valve of the balance auxiliary mechanism to make the above-mentioned gravity balance and mechanical spring balance compatible cantilever in the best balance state.
