[0047] In this invention, a method for using an intraoperative assistive turning device for spinal surgery includes the following steps:

[0048] Step 1: When the patient needs to turn over during spinal surgery, the electric telescopic rod 48 is activated by the controller 6. The output end of the electric telescopic rod 48 extends, pushing the two round rods 46 to move in opposite directions, thereby causing the clamping plate 45 to rotate around the round rod 44 as the axis. During the rotation, the rotating plate 410 will rotate on one side of the compensation plate 49 and the compensation plate 411 to ensure the stable rotation of the clamping plate 45. At the same time, when the electric telescopic rod 48 is activated, it will drive the round rod 46 to rotate in the inner cavity of the clamping plate 45 to compensate for the rotation of the clamping plate 45. Finally, the clamping plate 45 completes the fixation of the patient's leg.

[0049] Step 2: Start motor 2 52 via controller 6. Its output shaft drives bidirectional threaded rod 53 to rotate. When bidirectional threaded rod 53 rotates, it drives two threaded blocks 1 54 to move relative to each other through the threads on its surface. Threaded blocks 1 54 drive moving block 1 55 to move in the same direction. When moving, moving block 1 55 will slide in the inner cavity of guide hole 1 56. Guide hole 1 56 is set to limit and guide moving block 1 55. Then, when moving, moving block 1 55 drives clamping plate 3 515 to move under the action of working shell 2 57. Clamping plate 3 515 is used to fix the patient's shoulder.

[0050] Step 3: When motor 3 59 starts, its output shaft will drive the one-way threaded rod 510 to rotate. When the one-way threaded rod 510 rotates, it will drive the threaded block 2 511 to move. The threaded block 2 511 will drive the moving block 2 512 to slide in the inner cavity of the guide hole 2 513. Under the action of the guide hole 2 513, the moving block 2 512 will be limited and guided. Then, when the moving block 2 512 moves, it will drive the clamping plate 2 514 to move. The clamping plate 2 514 is used to fix the patient's buttocks. When the moving block 2 512 moves, it will drive the support plate 10 to move in the same direction to provide stable support for the patient's back.

[0051] Step 4: Activate the two motors 3 via controller 6 to drive the fixation components 4 and 5 to rotate, thereby enabling the patient to turn over.
