The traction device 60 is a common device in the art, and its structure and principle refer to the prior art, which will not be repeated here.

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

[0041] The use process of the intraoperative three-dimensional traction component proposed by the present invention is as follows:

[0042] The patient's torso lies on the operating table, and the patient's head lies in the receiving groove 401 of the cushion block device 40 of the base 10, with the mouth and nose aligned with the second ventilation groove 402. The cushion block device 40 is adjusted by the six adjustment rods 50: the second locking member 902 of the second locking device 90 is unscrewed, and each adjustment rod 50 drives each cushion block to move to a suitable position according to the size of the patient's face (mainly to move each adjustment rod 50 horizontally along its axial direction according to the width of the patient's face), and then the second locking member 902 is tightened again after the movement. The six adjustment rods 50 are only loosened when adjusting their own positions, and are locked at the top of the base 10 at other times.

[0043] The patient is pulled by the traction device 60: a hole is drilled at a designated position on the patient's skull with a limited depth drill bit, 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 a screw 604 (the traction bow 603 in the figure is not suspended in the air, but is fixed on the patient's skull, but the patient and his skull are not drawn), and then the traction rope 605 is tied to the middle of the traction bow 603, and the traction rope 605 passes through the pulley 602, and the traction object 606 is tied to the end of the traction rope 605. The weight of the traction object 606 can be appropriately changed according to the degree of traction. During traction, not only the patient's skull is pulled and moved away from the operating bed, but the base 10 with the brake roller 30 is also indirectly driven to move away from the operating bed, and the pad device 40 fixed on the base 10 also moves with it, which is equivalent to the front face of the patient and the pad device 40 being relatively still, reducing the risk of the face being rubbed by the pad device 40.

[0044] During the traction process, in order to achieve a better traction effect, the patient's skull and cervical spine can be flexed, tilted backward, rotated left or right as needed to achieve a three-dimensional traction effect: lower the first lifting rod 201 and the third lifting rod 203, raise the second lifting rod 202 and the fourth lifting rod 204, so that the top of the base 10 is tilted away from the operating bed to achieve "flexion"; lower the second lifting rod 202 and the fourth lifting rod 204, raise the first lifting rod 201 and the third lifting rod 203, so that the top of the base 10 is tilted toward the direction close to the operating bed to achieve "tilt / extension"; lower the first lifting rod 201 and the second lifting rod 202, raise the third lifting rod 203 and the fourth lifting rod 204, and achieve "left rotation"; lower the third lifting rod 203 and the fourth lifting rod 204, and raise the first lifting rod 201 and the second lifting rod 202 to achieve "right rotation".

[0045] After the traction is completely completed, the traction object 606 is removed, and then the screw 604 is loosened to remove the traction bow 603.

[0046] The embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
