Abstract
The utility mode relates to a fixed device for head radiation treatment, which comprises a U-shaped base and two cambered follow blocks which are symmetrically arranged in the U-shaped base, wherein, the middle of the two cambered follow blocks presents a concave shape after being folded. Springs are respectively arranged between the two cambered follow blocks and two lateral plates of the U-shaped base. An adjustable ledger plate is arranged at the upper end of one side of the cambered follow blocks which are close to the lateral plate of the U-shaped base; an oblong hole is arranged on the adjustable ledger plate; a fixed bolt is arranged in the oblong hole. The adjustable ledger plate is connected with the top surface of the lateral plate of the U-shaped base through the fixed bolt and the oblong hole; cambered sponge cushions are arranged on the cambered follow blocks. The fixed device has the advantages that because the springs are arranged between the U-shaped base and the cambered follow blocks, the distance between the two cambered follow blocks can be automatically regulated according to the difference of the head appearances of patients, and then the two cambered follow blocks are positioned by the fixed bolt, the positioning is accurate, the operation is convenient, in addition, the sponge cushions are arranged on the cambered follow blocks, so the use is comfortable.
