[0040] In the embodiment, the traction bow 603 is in the shape of a semicircular ring, and the traction object 606 is a weight.

[0041] The use process of the intraoperative three-dimensional traction assembly is as follows:

[0042] The patient's torso is placed face down on the operating table, and the patient's head is placed in the accommodating groove 401 of the cushion device 40 on the base 10, with the mouth and nose aligned with the second air-permeable groove 402. The adjustment of the cushion device 40 is started by adjusting the six adjustment rods 50: the second locking member 902 of the second locking device 90 is loosened, each adjustment rod 50 is used to move each sub-cushion to the appropriate position according to the size of the patient's face (mainly according to the width of the patient's face to move each adjustment rod 50 horizontally along its axial direction), and then the second locking member 902 is tightened. The six adjustment rods 50 are loosened only when adjusting their positions, and are locked on the top of the base 10 at all other times.

[0043] The patient is pulled by the traction device 60: a drill with a limited depth is used to drill a hole in a designated position on the patient's skull, the depth of which does not exceed the inner plate of the skull, and then the traction bow 603 is placed on the skull and fixed with the screw 604 (the traction bow 603 in the figure is not suspended in the air, but is fixed to the patient's skull, only the patient and his skull are not drawn), and then the traction rope 605 is tied in the middle of the traction bow 603, passes through the pulley 602, and the traction object 606 is tied at the end of the traction rope 605. The weight of the traction object 606 can be appropriately changed according to the degree of traction.
