[0002] Radiology is an important auxiliary examination department in hospitals. In the construction of modern hospitals, radiology is a department that integrates examination, diagnosis and treatment. Many diseases in various clinical departments must be examined by radiology equipment to achieve clear diagnosis and auxiliary diagnosis. Radiology diagnosis mainly has vertical or horizontal examinations. The horizontal examination is to lie on the bed for examination. Most bed boards are flat. Some patients' limbs often shake involuntarily during diagnosis, and the shaking of limbs will cause unclear radiological diagnostic images, which makes it impossible for doctors to make effective judgments on the condition. Radiological diagnosis needs to be performed again, which is time-consuming, labor-intensive and wastes medical resources. In order to avoid patients' random activities, when patients undergo radiological diagnosis, fixation tools will be used to fix the patient's limbs. Although the solution in the "A Limb Fixation Device for Radiology Diagnosis" with patent number "CN215820964U" solves the problem that the existing fixation device cannot be adjusted according to the different body shapes of patients and the fixation effect is poor, the structure of the patient's limb fixation in the device is relatively complex, the adjustment operation process is inconvenient, and the adjustment range is still limited, and the applicability is still not strong.
