Figure 1 Only the rigid support part of the U-shaped chin support is shown, but in order to achieve comfortable and reliable fixation of the U-shaped chin support and the human mandible, those skilled in the art can think of adding air bags or flexible sponge pads, etc.). The structure of the wearing component 12 can be obtained in the prior art. Its specific structure is not an innovative design of the present invention, so its specific structure will not be described in detail. The suspension support mechanism includes a plurality of support air bag units distributed in the inner cavity of the rigid helmet body 11, and the support air bag units include a forehead air bag 131, a left temporal air bag 132, a right temporal air bag 133, and a central air bag. 130, left mid-temporal air cell 134, right mid-temporal air cell 135, occipital air cell 136, left posterior temporal air cell 137, and right posterior temporal air cell 138. The locations of these head regions are as follows: Frontal region: located at the center of the forehead, extending from behind the hairline to the anterior one-third of the midline of the head; Central region: located at the center of the head, extending from the posterior frontal region to the middle and posterior part of the head (approximately midway along the midline); Posterior occipital region: located at the most prominent part of the back of the head, from the posterior part of the central region to the upper part of the neck; Anterior temporal region: located approximately 2-3 cm above and in front of the auricle, near the temple. Mid-temporal region: located directly above the auricle, approximately 3-4 cm behind the anterior temporal region. Posterior temporal region: located at the posterior and superior part of the auricle, extending from the posterior part of the mid-temporal region to the parietal junction. Each support airbag unit is independent of each other, allowing the corresponding support airbag unit to be deflated to form an airtight cavity. A flexible lining 14 is provided on the rigid helmet body 11, covering the inner side of the support airbag unit. The edges of the flexible lining 14 are fixed to the rigid helmet body 11. The flexible lining can be made of materials designed as needed, such as antibacterial and breathable fabrics. The flexible lining also includes a flexible rubber frame 14-1. A skilled artisan can design the inflation and deflation control circuitry for the support airbag units based on existing technology, such as a main air source → distributor → nine independent branches (each branch includes an inlet valve, an exhaust valve, and an airbag), with check valves installed in each branch to prevent main pressure fluctuations from affecting other airbags. The figure shows the airbag circuitry as being bundled within a flexible sleeve that extends from the rigid helmet body, so the specific piping design will not be detailed here. Each of the support airbag units is correspondingly configured with a pressure sensor, which detects the supporting pressure of the support airbag unit on the head and adjusts the filling degree of the support airbag unit according to the pressure signal of the pressure sensor.

Furthermore, isolation bosses 112 are provided adjacent to the adjacent support airbag units, and the ventilation holes 111 are correspondingly located between the isolation bosses 112. On the one hand, the isolation bosses 112 form a positioning cavity for positioning the support airbag units on the inner side of the rigid helmet body, and on the other hand, the isolation bosses provide isolation protection for the ventilation holes to ensure breathability.

The base 21 is provided with a positioning seat 23, and the positioning seat 23 is provided with a tilt angle adjustment seat 24. The tilt angle adjustment seat 24 has a positioning cavity 241. A positioning portion 113 is provided at the position of the rigid helmet body 11 corresponding to the occipital area. The positioning portion 113 is positioned in the positioning cavity 241, and the helmet-shaped support device 1 can swing left and right with the tilt angle adjustment seat 24. The positioning seat 23 is provided with a head tilt angle adjustment mechanism for driving the tilt angle adjustment seat 24 to swing left and right.An arc-shaped toothed guide surface 231 is provided on the positioning seat 23, and an arc-shaped meshing tooth surface 242 is provided at the bottom of the roll angle adjustment seat 24. The arc-shaped meshing tooth surface 231 meshes with the arc-shaped toothed guide surface 242, thereby enabling the roll angle adjustment seat 24 to roll along the arc-shaped toothed guide surface 231. The head roll angle adjustment mechanism includes a driving component and a stabilizing component respectively provided at both ends of the roll angle adjustment seat 24. A connecting seat 243 is provided at both ends of the roll angle adjustment seat 24. The driving component includes an active traction member 251, a nut member 252 and a drive motor 250. The active traction member 251 includes a first hinge The joint part 2511 and the threaded rod 2512, the threaded rod 2512 is restricted to slide longitudinally on the positioning seat 23, specifically, a central positioning hole is provided on the threaded rod 2512, a guide rod 2311 is provided on the positioning seat 23, the guide rod is inserted into the central positioning hole, the first hinged joint 2511 is hinged to the connecting seat 243 via a hinge shaft and can adapt to the relative displacement between the active traction member 251 and the roll angle adjustment seat 24, a strip hole is provided on the connecting seat 243, the hinge shaft passes through the strip hole, thereby achieving the adaptation to the relative displacement between the active traction member 251 and the roll angle adjustment seat 24, the nut member 252 is threadedly screwed on On the threaded rod 2512, a gear part 253 is formed on the nut part 252, and the gear part 253 is positioned and rotated to fit on the positioning seat 23. The gear part 253 is engaged with a worm, and the worm is driven by the drive motor 250; in order to achieve a compact design, the gear part, the drive motor, the active traction part and other related accessories are integrated on the motor frame, and the motor frame is fixed to the positioning seat 23. The stabilizing assembly includes a stabilizing member 261 and a spring 262. The stabilizing member 261 has a second hinge head 2611 and a positioning shaft 2612. The positioning shaft 2612 is restricted to slide longitudinally on the positioning seat 23. The second hinge head Part 2611 is hinged to the connecting seat via a hinge shaft and can adapt to the relative displacement between the stabilizing member 261 and the roll angle adjustment seat 24. A strip hole is provided on the connecting seat, and the hinge shaft passes through the strip hole, thereby adapting to the relative displacement between the stabilizing member 261 and the roll angle adjustment seat 24. The spring 262 is sleeved on the positioning shaft, and one end of the spring 262 abuts against the axial limiting flange 2613 at the end of the positioning shaft (a bolt screwed on the end of the positioning shaft can be used), and the other end of the spring 262 abuts against the positioning seat 23. The spring 262 provides a downward push for the stabilizing member 261 to constitute a downward traction on the roll angle adjustment seat 24. The motor drives the gear part to rotate through the worm, and the nut part rotates. The nut part drives the active traction part to move longitudinally, and the active traction part pulls the roll angle adjustment seat. At the same time, the spring and the stabilizer form traction on the roll angle adjustment seat; the arc-shaped meshing tooth surface at the bottom of the roll angle adjustment seat engages with the arc-shaped tooth guide surface, so that the roll angle adjustment seat finally swings back and forth, thereby realizing the adjustment of the patient's head offset angle to the left and right.

[0017] At the same time, the neck support cushion 22 can be raised and lowered on the base 21, and the neck support cushion 22 is provided with a neck height driving component for driving the neck support cushion 22 to rise and fall to adjust the neck support height. The neck height driving component of the neck support cushion 22 can be driven by an airbag (the figure shows the airbag drive, and the figure shows the air tube 221 connected to the airbag), or a cam mechanism can be used, that is, the neck support cushion is driven to rise and fall by the rotation of the cam. Of course, it can also be realized by a motor-driven nut and screw mechanism, or a sloped driving mechanism with inclined surface pushing, etc. The liftable neck support pillow is a conventional technology in this field, so its specific structure will not be described in detail; at the same time, the helmet-shaped support device 1 is confined in the positioning cavity 241 and can slide in the positioning cavity 241 in the longitudinal direction, thereby forming a forward flexion or backward position of the head when the neck height is adjusted. Position adjustment: Specifically, a lateral limiting protrusion and an articulated seat are formed on the positioning portion 113 of the rigid helmet body 11. The lateral limiting protrusion cooperates with the positioning cavity to limit the left and right directions of the helmet-shaped supporter. The articulated seat 1131 is hinged in the positioning cavity to limit the helmet-shaped supporter to the lateral tilt angle adjustment seat 24. In order to adapt to the relative displacement between the rigid helmet body 11 and the lateral tilt angle adjustment seat 24 when the head is bent forward or tilted backward, a long strip hole extending along the front-to-back direction (perpendicular to the left and right directions and the height direction) is used on the connecting seat in the positioning cavity to which the articulated seat is connected. The helmet-shaped supporter 1 is supported on the lateral tilt angle adjustment seat 24 to limit the height of the helmet-shaped supporter 1. In this way, when the neck height is adjusted, the head support height is limited, thereby achieving the adjustment of the head's forward flexion or backward position. The post-cranial cerebral surgery suspension support device of the present invention not only ensures the safety of diagnosis and treatment, but also takes into account the patient's physiological comfort needs in a more comprehensive manner.
