Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head fixing device. Background Art

[0002] Otolaryngology is a surgical discipline that diagnoses and treats the ears, nose, pharynx, larynx, and related head and neck areas. With the advancement and development of science and technology, various medical disciplines have penetrated and promoted each other, expanding the scope of otolaryngology. Ear microsurgery, ear neurosurgery, skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal neurosurgery, head and neck surgery, laryngeal microsurgery, voice and speech disease department, pediatric otolaryngology, etc. have emerged. In life, children have thin throats and are prone to food getting stuck when eating. Children are prone to moving around during daily examinations, so head fixation is needed to assist in treatment and examination.

[0003] A head fixation device for otolaryngology and head and neck surgery disclosed in the Chinese utility model patent application disclosure specification CN215130404U, although through the interaction between the set compression spring and the compression airbag, when the patient's head is fixed on the upper end of the fixed clamp block and subjected to external force, the fixed clamp block is pressed down to drive the compression spring and the compression airbag to compress, which can buffer and offset the external force generated on the patient's head, avoiding the doctor from using too much force during treatment and causing discomfort to the patient's head. The electric telescopic rod can be controlled by the set control switch to extend and retract, so that the angle of the head fixation plate body can be adjusted, which is convenient for the doctor to adjust the angle of the patient's head. In order to find a suitable treatment position, the rubber cushion can prevent the patient's head from feeling uncomfortable due to the pressure of the fixing clamp when it is fixed. The rotating screw can be used to control the fixing clamp to press down and fix the patient's head. However, the device only fixes the head and the doctor adjusts the angle when fixing it. However, for examination and treatment of children, children are more afraid than adults, which may cause the hands to move around and affect the treatment. During treatment, children have smaller throats and need to tilt their heads to assist in treatment. In addition, treatment requires children to divert their attention through external influences to speed up the treatment. Therefore, a utility model is proposed to solve the above problems.
