In the treatment room of proton heavy ion fixed beam, the proton heavy ion therapy chair assists the patient to complete the sitting position, so that the ion beam can be irradiated from the appropriate position. Proton heavy ion radiotherapy chair is designed to meet the needs of proton heavy ion sitting position radiotherapy, mainly including two parts: position adjustment mechanism and head fixation device. After the design was completed, the stress analysis was carried out on the weak parts of the treatment chair, and the kinematics analysis was carried out for the adjustment mechanism of the treatment chair position. It turns out that the design of each part of the treatment chair can meet the requirement of load-bearing capacity, and also can satisfied the demand of the position and the posture requirement of proton heavy ion radiotherapy.
