Example two: the retainer 10 has six spatial degrees of freedom, wherein the retainer 10 is rotationally connected with the rotating frame 9 to form a transverse axis rotational degree of freedom, the rotating frame 9 is rotationally connected with the chute frame 8 to form a longitudinal axis rotational degree of freedom, the chute frame 8 is rotationally connected with the transverse swing arm 7 to form a vertical axis rotational degree of freedom, the lifting action of the lifting column 5 forms a vertical axis moving degree of freedom, the back and forth movement of the guide cylinder 2 forms a longitudinal axis moving degree of freedom, and the transverse swing arm 7 is rotationally connected with the lifting column 5 to form a transverse axis moving degree of freedom; the rich freedom allows the holder 10 to achieve multi-angle traction on the patient's head.
Example three: the electric cylinder 4 drives the guide cylinder 2 to move backwards so that the retainer 10 can realize traction on the head of the patient; when the transverse swing arm 7 is in a longitudinal state and the center of the rotating frame 9 is as high as the center of the head of the patient, the longitudinal axis traction can be realized on the head of the patient; when the transverse swing arm 7 is in a longitudinal state and the center of the rotating frame 9 is higher than the center of the head of a patient, the head of the patient can be dragged upwards in a deviation manner; when the transverse swing arm 7 is in a longitudinal state and the center of the rotating frame 9 is lower than the center of the head of the patient, the head of the patient can be dragged to be deflected downwards; when the transverse swing arm 7 rotates leftwards and is positioned, the retainer 10 can move leftwards and the rotating frame 9 deflects clockwise, so that the head of the patient is drawn to deflect leftwards; when the transverse swing arm 7 rotates rightwards and is positioned, the retainer 10 can move rightwards, and the rotating frame 9 deflects anticlockwise, so that the head of the patient is drawn to be deviated to the right.
Example four: the lifting column 5 can adjust the supporting height of the head of the patient, the second pressure sensor 19 can monitor the supporting force of the head of the patient in real time, and after stable support is formed, the control system can set the pressure value measured by the second pressure sensor 19 as a standard value A; when the pressure value detected by the second pressure sensor 19 is smaller than A, the lifting column 5 can be lifted upwards until the pressure value detected by the second pressure sensor 19 is equal to A; when the pressure value detected by the second pressure sensor 19 is greater than A, the lifting column 5 can be lowered downwards until the pressure value detected by the second pressure sensor 19 is equal to A; therefore, when the body position of the patient is changed in the operation, the height position of the head of the patient is inevitably fluctuated, and in the process, the lifting column 5 can move up and down dynamically according to the pressure monitored by the second pressure sensor 19 all the time and provide stable support and traction for the head of the patient all the time.
Example five: when the patient needs to change between the supine position and the prone position, the head of the patient can rotate with the body, the locking wheel 13 is firstly unscrewed anticlockwise before the patient is turned over, the rotating frame 9 can rotate freely, and the retainer 10 can drive the rotating frame 9 to rotate freely along the longitudinal axis in the process of turning the patient.
