Biological tissues can be penetrated by short-wave components in the electromagnetic spectrum, such as X-rays, and are applicable to the diagnosis of different diseases in almost all systems of the body, especially for the diagnosis of diseases of the brain, spine, etc. At present, when performing a head MRI scan on a patient, the patient is required to lie on the examination bed and use a head fixator to fix the patient's head to prevent the patient's head from moving and causing inaccurate examinations. However, when the existing nuclear magnetic resonance examination restraint fixator is in use, the adjustable range of the restraint fixation plate is generally fixed, and the fixed limit can only be roughly adjusted according to the patient's head circumference. The patient's head cannot be tightly squeezed and limited, which may cause the examination data to be inaccurate and require repeated examinations. For this reason, we propose a nuclear magnetic resonance examination restraint fixator. Utility Model Content
