furthermore, a head circumference adjusting device is arranged on the top surface of the operating table 1 and comprises two adjusting blocks 32, the two adjusting blocks 32 are respectively connected inside the two adjusting grooves 31 in a sliding manner, the back ends of the two adjusting blocks 32 are fixedly connected with arc-shaped plates 33, the two arc-shaped plates 33 are respectively connected with the operating table 1 in a sliding manner, the arc-shaped plates 33 are arranged to be more fit with the contour of the human head, the top surfaces of the two adjusting blocks 32 are respectively connected with bolts 34 in a threaded manner, and the two bolts 34 respectively penetrate through the two adjusting blocks 32 and are connected with bolt holes 38 in a threaded manner;

further, when the device is used, a patient lies on the headrest 30, the two arc plates 33 are slid to enable the two arc plates 33 to be in contact with the head of the patient, then the bolts 34 are in threaded connection with the corresponding bolt holes 38, the adjusting block 32 is firmly fixed, the adjusting block 32 is prevented from sliding in the using process, and the device can be adjusted according to the head circumference of the patient, the device has a limiting and fixing function on the head of the patient, avoids the head of the patient from shaking during the operation, thereby improving the safety and the stability of the operation, preventing the patient from falling off the operating table 1 through the arrangement of the protective device, when the patient collides with the stop lever 37, the force generated by the impact drives the spring 36 to deform, the spring 36 absorbs the impact force, thereby playing a buffering protection effect to protector's life has been promoted.

The working principle is as follows:

firstly, a patient lies on the headrest 30, the two arc plates 33 are slid to enable the two arc plates 33 to be in contact with the head of the patient, then the bolts 34 are in threaded connection with the corresponding bolt holes 38, the adjusting block 32 is firmly fixed, and the sliding of the adjusting block 32 in the using process is avoided;

secondly, a user holds the handle 9 to pull, the handle 9 drives the moving rod 8 to move, and after the moving rod 8 moves to a proper position, the fixing pin 16 is inserted into the corresponding fixing hole 17, so that the moving rod 8 is fixed to prevent the moving rod 8 from moving in the using process, and the stability of the device is improved;

thirdly, the hand wheel 12 is rotated to drive the first threaded rod 19 to rotate, the first threaded rod 19 rotates to drive the first threaded sleeve 20 to move, the first threaded sleeve 20 moves to drive the protecting sleeve 21 to move, the protecting sleeve 21 moves to drive the drainage tube 11 in the connecting groove 23 to move, so that the drainage tube 11 is transversely moved, and the shape and the movement path of drainage are simulated by capturing the position of the tracking block 13, so that the accurate real-time position of the implant is obtained;

fourthly, the starting motor 24 drives the second threaded rod 25 to rotate, the second threaded rod 25 rotates to drive the second threaded sleeve 26 to move, the second threaded sleeve 26 drives the two connecting blocks 27 to move, the two connecting blocks 27 drive the two supporting rods 29 to move, the two supporting rods 29 drive the two sliding blocks 15 to move inside the two clamping grooves 14, and the two sliding blocks 15 move to drive the moving block 6 to move inside the groove 5;

and fifthly, the moving block 6 moves to drive the longitudinal adjusting device and the transverse adjusting operation device to move, so that the height of the longitudinal adjusting device and the height of the transverse adjusting operation device are adjusted, and the height can be adjusted through the device.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
