Through the fixed block, the connection frame can be driven to slide on the outer wall of the support frame, and then the overall height can be adjusted as required.
[0016] While the connecting frame slides, it drives the spur gear to rotate on the rack through the second threaded rod, and then drives the second threaded rod to rotate through the spur gear.

[0018] This device not only achieves the effect of adjusting the height of the device as needed. The doctor can adjust the thoracoscope to the best position according to the needs of the surgical site and angle, so as to observe the surgical area more clearly. By adjusting the height, the doctor can find the best surgical field of view faster, reduce the operation time and difficulty, and improve the operation efficiency.
[0019] It also achieves the effect of clamping and fixing the thoracoscope, which can ensure the stability of the field of view during the operation, avoid the influence of the thoracoscope shaking or moving on the operation, and the stable field of view helps the doctor to judge the surgical site and depth more accurately, improving the precision and safety of the operation.
[0020] It also achieves the effect of adjusting the tilt angle of the thoracoscope as needed, which can enable the doctor to obtain a wider surgical field of view, observe the surgical area more comprehensively, reduce the surgical blind area. The appropriate tilt angle can reduce the compression and discomfort of the patient during the operation, improving the patient's surgical experience and comfort.

[0022] 1. In the present invention, the motor drives the connecting column to rotate in the support frame, and then the connecting column drives the second bevel gear to rotate through the first bevel gear, and then drives the first threaded rod to rotate, so that the fixing block on the connecting plate can be driven to slide in the first chute, and then the connecting frame can be driven to slide on the support frame, achieving the effect of adjusting the height of the device as needed.
[0023] 2. While the connecting frame slides in the present invention, it drives the spur gear to rotate on the rack through the second threaded rod, and then drives the second threaded rod to rotate through the spur gear. Then, the second threaded rod drives the connecting block to slide in the second chute, and the connecting block drives the limiting block to slide on the slide rail through the clamping arm, achieving the effect of clamping and fixing the thoracoscope.
