Auxiliary body position fixing apparatus for radiotherapy

Abstract

The present disclosure relates to the technical field of medical instruments, and discloses an auxiliary body position fixing apparatus for radiotherapy. The auxiliary body position fixing apparatus includes a base bed and two fixing columns. A movable bed board is disposed inside a top end of the base bed. A sub-mat wrapping core-shell structure composite microspheres is disposed inside the movable bed board. A temperature adjustment assembly is disposed inside the base bed. A position adjustment assembly is disposed between ends of the fixing columns and configured to drive lifting and clamping assemblies on two sides to move transversely. Pressing plate assemblies are disposed at bottoms of the lifting and clamping assemblies. The temperature adjustment assembly generates hot air and cold air to soften and solidify the core- shell structure composite microspheres inside the sub-mat, thereby perfectly fitting and shaping a figure of the back of a patient. The pressing plate assemblies are aligned to an abdomen of the patient by using dovetail sliding rails and the position adjustment assembly, and the pressing plate assemblies are driven by the lifting and clamping assemblies to press down to closely fit and lock an abdominal wall, thereby restricting respiratory fluctuations of the patient and preventing a tumor in a target region from shifting.
