It is a device used to fix the patient's head and neck, usually made of adjustable metal or plastic materials, with multiple fixing points and support points to ensure that the patient's head posture is correct and comfortable; allowing doctors to operate better to ensure safety and accuracy; the existing head posture adjustment support device for ENT clinical surgery (publication number: CN215193383U) includes a base plate provided with a soft cushion A, the back of the base plate is hinged with a lifting plate by a hinge, and support components are provided on both sides of the upper surface of the lifting plate, and a rotating seat for plugging in a swivel is fixedly connected in the middle of the upper surface of the lifting plate, and a pillow plate is fixed on the upper surface of the swivel. The main advantage of the utility model is to provide a head posture adjustment support device for ENT clinical surgery; at least the following defects are exposed during use:

[0003] 1. Referring to the above-mentioned literature, personnel bend the support rod downward to make the lifting plate lift the patient's head. However, since the ears, nose, and pharynx are located in different parts of the human brain, the patient's head usually needs to be adjusted to different angles during ENT medical surgery. The above-mentioned device may not be able to adjust the angle of the patient's head, so personnel need to manually adjust the angle of the patient's head, which may easily lead to inaccurate adjustment, thereby causing inconvenience to the doctor's operation during the operation.

[0004] 2. Usually, after the patient's head is adjusted, the patient's head is directly placed against the headrest. Due to the adjustment of the patient's head, the force on the headrest is uneven, and the patient's head may move on the surface of the headrest, thereby affecting the surgical operation and reducing the accuracy and safety of the operation. Utility Model Content
