Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a head fixation device for post-operative brain surgery. Background Art

[0002] Brain surgery is a specialized procedure performed by neurosurgeons to treat brain diseases. Ventricular drainage is usually performed after brain surgery to drain the fluid accumulated in the ventricles to the outside of the body to relieve the intracranial pressure symptoms caused by hydrocephalus. When caring for patients after brain surgery, they are placed in a supine or lateral position. Patients who are unconscious or agitated need to be restrained to prevent them from pulling out the drainage tube on their own and causing accidents. Restraining the patient's head is a routine postoperative care method for brain surgery.

[0003] Most existing head fixation devices are U-shaped clamp-like structures, such as the technical structures disclosed in head fixation and nursing devices with announcement numbers CN110559144B, CN110721041B, and CN113180959B. These are only suitable for restraining and fixing the patient's head when the patient is in a supine position after brain surgery. However, if the patient continues to lie flat, it is easy to cause pressure sores. After lying flat for a certain period of time, the caregiver will help the patient to lie sideways and switch between the supine and lateral positions. Therefore, although the existing head fixation device can be used to restrain and fix the patient's head when the patient is in a supine position, it is not suitable for restraining and fixing the patient's head when the patient is in a lateral position. When the patient switches from a supine position to a lateral position, the head fixation device must first release the restraint on the patient's head, which is a more cumbersome operation. Summary of the Invention

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a head fixation device after brain surgery, which is used to restrain and fix the patient's head after brain surgery. The clamping and restraining mechanism of the head fixation device is rotatable. When the patient switches between a supine position and a lateral position, the clamping and restraining mechanism is controlled to rotate, and there is no need to release the restraint on the patient's head, which is convenient for operation.

[0005] The present invention is achieved through the following technical solutions:
