DETAILED DESCRIPTION

[0028] Combine Figure 1-7 As shown:

[0029] An adjustable headrest comprises a base plate 1, with a forehead pad mechanism 2 and a mandibular mechanism 3 connected to the top of the base plate 1 via a lifting mechanism, the forehead pad mechanism 2 comprising a forehead pad 4, the left and right ends of the forehead pad 4 being fixedly connected to a rotating shaft 5, a connecting rod 6 being rotatably sleeved on the rotating shaft 5, a forehead pad slider 7 being fixedly provided at the lower end of the connecting rod 6, a forehead pad screw 8 being threadedly connected to the forehead pad slider 7, a forehead pad fixing seat 9 being provided below the forehead pad slider 7, and a forehead pad knob 10 being provided at the side end of the forehead pad fixing seat 9.

[0030] Specifically, the forehead pad mechanism 2 is used for supporting the forehead, and the mandibular pad mechanism 3 is used for supporting the mandibular.

[0031] Specifically, when lying prone, the forehead of the head rests on the concave cavity of the forehead pad 4 , and the lower jaw rests on the platforms of the left lower jaw pad 11 and the right lower jaw pad 12 .

[0032] Specifically, the mandibular pad is divided into a left mandibular pad and a right mandibular pad, and is symmetrically arranged on both sides.

[0033] Specifically, the forehead pad mechanism is provided with a forward and backward moving mechanism and a flipping mechanism; the forward and backward moving mechanism can move forward and backward relative to the chin pad mechanism to adjust the distance between the forehead pad and the chin pad, thereby adapting to people of different head sizes; the flipping mechanism can adjust the angle of the forehead pad to adapt to the angle when a person turns his head, thereby improving the comfort and experience of use.

[0034] Specifically, the left mandibular pad 11 and the right mandibular pad 12 can move relative to each other, thereby adapting to different sizes of human mandibulars and improving comfort in use.

[0035] Specifically, the forehead pad can be fixed at a certain angle by means of the latch.

[0036] Specifically, the gel material has been specially processed to be soft enough to adapt to the different head and facial shapes of different patients, yet possesses the appropriate hardness to ensure stable support during prolonged surgeries. The material's unique viscoelasticity allows for even pressure distribution and allows for corresponding shape adjustments as the patient's head shape changes, such as creating depressions at the pressure point to disperse the force, thereby reducing single-point pressure and minimizing the risk of pressure sores.

[0037] In terms of material selection, gel has excellent adaptability, allowing it to adapt its shape to the pressure applied to different areas of the patient's head, thereby achieving dynamic pressure dispersion. This property is crucial for reducing local tissue compression, especially during prolonged surgeries, where it can significantly reduce the risk of pressure ulcers. The gel's adaptability also means that the head cushion can adapt to heads of different sizes and shapes without mechanical adjustments such as expansion, improving ease of use.
