[0033] The head fixing device is used to fix the head of a patient in a prone position, so as to reduce the interference of the patient's head movement to the operation during the operation and reduce the risk of the operation. When the head fixing device is used, the head of the patient in a prone position is located between the forehead seat 1 and the mandibular seat 2, so that the forehead part abuts against the forehead seat 1 and the mandibular part abuts against the mandibular seat 2, thereby positioning the patient's head through the forehead seat 1 and the mandibular seat 2. The forehead seat 1 is a U-shaped structure, including an arc section and two straight sections, the arc section half surrounds the forehead part to realize the positioning of the forehead part, and the straight section can extend to the cheek part and abut against the cheek part. The cheek area is supported and positioned, thereby improving the stability of head positioning, and the eyes, nose and mouth can be located on the inner side of the U-shaped structure, so that the patient can breathe normally during surgery and improve comfort; the recessed portion 201 on the mandibular seat 2 is used to accommodate the mandibular area, thereby achieving positioning of the mandibular area and further improving the stability of head positioning; the fixing belt 3 is used to bind the head to the forehead seat 1 and the mandibular seat 2 to prevent the head from detaching, thereby further improving the stability and firmness of head fixation. By stably positioning the head, the interference caused by head movement during surgery can be reduced, thereby improving the safety of the surgery.

[0034] Since the head shapes of different patients are different, the distance between the forehead seat 1 and the mandibular seat 2 can be adjusted through the adjustment mechanism, so that the fixing device can adapt to the head fixation of patients with different head shapes, thereby improving the practicality of the fixing device and the comfort of the patients during surgery; the setting of the suction cup assembly can firmly adsorb the fixing device on the operating table, thereby improving the stability of the fixing device, preventing it from displacement, and further improving the stability of the fixing device on the patient's head; and the setting of the suction cup assembly also facilitates the disassembly and assembly between the fixing device and the operating table, thereby improving the convenience of disassembly and assembly of the fixing device, and also facilitates the adjustment of the fixed position of the fixing device on the operating table, thereby improving the convenience of using the fixing device.

[0035] A further improvement is, Figure 2 As shown, the adjustment mechanism includes a plug-in hole 105 and a plug-in column 202 that are slidably matched. The plug-in hole 105 is opened on the end surface of the forehead seat 1, and the plug-in column 202 is fixedly connected to the mandibular seat 2. A locking piece is provided between the plug-in hole 105 and the plug-in column 202. The plug-in column 202 is plug-fitted with the plug-in hole 105, so that the plug-in column 202 can slide along its axial direction inside the plug-in hole 105, so that the mandibular seat 2 can move along the opening direction of the U-shaped structure of the forehead seat 1, thereby realizing the distance adjustment between the forehead seat 1 and the mandibular seat 2. When adjusted to a suitable position, the plug-in column 202 and the plug-in hole 105 are locked by the locking piece, so that the relative position between the forehead seat 1 and the mandibular seat 2 is fixed, so that the fixing device is suitable for patients with different head shapes, and the practicality of the fixing device is improved.

[0036] A further improvement is, Figure 2 , 3 As shown in FIG. 5 , the locking member includes a threaded through hole 104 provided on the side wall of the plug-in hole 105, and a hand screw 5 is connected to the threaded through hole 104. The plug-in column 202 is provided with a plurality of positioning holes 203 along its radial direction, and each positioning hole 203 is evenly spaced along the axial direction of the plug-in column 202, and the hand screw 5 is plugged and matched with one of the positioning holes 203. The hand screw 5 and the positioning hole 203 are mutually limited, so as to realize the mutual positioning between the plug-in column 202 and the plug-in hole 105, and finally improve the firmness of the connection between the forehead seat 1 and the mandibular seat 2. When the distance between the forehead seat 1 and the mandibular seat 2 needs to be adjusted, the hand screw 5 is screwed out from the inside of the positioning space 203, so that the plug-in column 202 can move along the plug-in hole 105, and the distance between the forehead seat 1 and the mandibular seat 2 can be adjusted.

[0037] A further improvement is, Figure 2 and 7 As shown, the suction cup 4 assembly includes a plurality of suction cups 4 evenly distributed on the bottom surfaces of the forehead seat 1 and the mandibular seat 2, the suction cup 4 is fixedly connected with a stud 401, and the bottom surfaces of the forehead seat 1 and the mandibular seat 2 are provided with a threaded hole 103 matching the stud 401. The stud 401 is threadedly matched with the threaded hole 103 to realize the disassembly of the suction cup 4 from the forehead seat 1 and the mandibular seat 2, and improve the convenience of disassembly, assembly and replacement of the suction cup 4; the suction cup 4 is adsorbed on the surface of the operating table, which can improve the firmness of the connection between the fixing device and the operating table, prevent the fixing device from being displaced during surgery, and thus improve the stability of the fixing device on the patient's head.

[0038] A further improvement is, Figure 7 As shown, a vent 402 is provided on the outside of the suction cup 4, one end of the vent 402 is connected to the inside of the suction cup 4, and a sealing plug 403 is provided on the other end of the vent 402. When the suction cup 4 is normally adsorbed, the sealing plug 403 seals the vent 402, and the suction cup 4 and the adsorption surface of the operating table are in a vacuum state, so that the suction cup 4 is adsorbed on the operating table under the action of atmospheric pressure to ensure the stability of the fixing device; when the fixing device needs to be removed, it is only necessary to remove the sealing plug 403 to allow external air to enter between the suction cup 4 and the adsorption surface of the operating table. At this time, the air pressure inside and outside the suction cup 4 is consistent, and the suction cup 4 can be easily removed from the operating table, thereby improving the convenience of disassembly and assembly of the fixing device, facilitating the maintenance of the fixing device and replacing the position of the fixing device adsorbed on the operating table, and improving the convenience of using the fixing device.

[0039] A further improvement is, Figure 2 , 3As shown in Figure 5, the bottom surfaces of the forehead seat 1 and the mandibular seat 2 are also provided with elastic anti-slip strips 102. The provision of the anti-slip strips 102 can increase the friction between the fixing device and the operating table, prevent the fixing device fixed on the operating table from slipping, further improve the stability of the fixing device, and ensure the stability of the patient's head positioning.

[0040] A further improvement is, Figure 3-6 As shown, the side surfaces of the mandibular seat 2 and the forehead seat 1 are provided with a belt hole 101, and the end of the fixing belt 3 is detachably connected to the belt hole 101; the end of the fixing belt 3 is provided with a hook surface 301 of Velcro, and the fur surface 302 of Velcro is distributed between the two hook surfaces 301 along the extension direction of the fixing belt 3.
