The invention relates to the technical field of
medical instruments, and provides a self-
adaptive radiotherapy body position fixing device capable of generating deformation based on pressure feeling in order to solve the problems that an existing radiotherapy
body position fixing mode is insufficient in adaptability and cannot be reused, the self-
adaptive radiotherapy body position fixing device comprises a
body frame plate, and a plurality of fixing grooves distributed in a human-shaped array are formed in the
body frame plate in a penetrating mode; the
pressure sensing mechanism is arranged in each fixing groove in a penetrating manner, and is configured to sense the pressure distribution and the pressure of a contact area of the body of the radiotherapy patient and the
body frame plate in real time, and generate elastic deformation of a corresponding degree based on pressure change so as to adaptively fit the contour of the body of the patient; and the
thermoplastic film is detachably arranged on the body frame plate. Personalized
adaptation of the
body contour of the patient can be achieved, meanwhile, repeated utilization can be achieved, disposable
consumables do not need to be replaced, the medical cost is greatly reduced,
medical waste pollution is reduced, operation is convenient and fast, body
position fixing and repeated calling can be rapidly completed, and radiotherapy accuracy,
patient comfort and radiotherapy turnover efficiency are improved to a certain degree.
