[0038] By adjusting and sliding the first side wing 312 and the second side wing 322 to infinitely adjust the distance therebetween, the headrest portion 2 can adapt to the width of different head shapes, thereby effectively fixing the head.

[0039] In a possible implementation, the first slide rail 311 and the second slide rail 321 are both disposed at the center of the headrest portion 2 along the head and neck direction to ensure that the first side wing 312 slidably connected to the first slide rail 311 and the second side wing 322 slidably connected to the second slide rail 321 are evenly stressed when clamping and fixing the head. Furthermore, the length of the first side wing 312 and the second side wing 322 along the head and neck direction is not greater than the length of the brain fossa portion 21 along the head and neck direction.

Optionally, there are at least two inflatable bags 43 in the head adjustment area 41.

[0043] In view of different head shapes and different surgical requirements, each adjustment area of ​​the adjustment part 4 can be adjusted by flushing and deflation. In a specific example, assuming that the head adjustment area 41 is provided with two airbags A and B in sequence from the head and neck direction, and the neck adjustment area 42 is provided with one airbag C, when the patient's head needs to be tilted upward, the A airbag can be inflated through the inflation port 44 first, and the A airbag is tilted upward to a suitable angle against the brain fossa 21, and then the B airbag is inflated to effectively support the brain fossa 21, and finally the air volume of the C airbag is adjusted to an angle that is comfortable for the patient at the intersection of the neck and the head. When the patient's head needs to be tilted back, the C airbag can be inflated first, and the cervical support 22 is lifted upward, and then the B airbag is inflated according to the upward lifting height, or the A airbag is deflated to adjust the head to a comfortable backward state.

[0044] The utility model provides a fixed headrest for surgery. By providing a clamping part with a slide rail, side wings and a guide rail locking mechanism, the surgical headrest is safely fixed for different head shapes. By providing multiple air bags, multi-angle adjustment of the head is achieved to meet the requirements of head positioning for different surgeries.
