Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] The head, neck, shoulder and body radiotherapy positioning board made of carbon fiber, such as the product of civco roper company in the United States, simulates the human body to form an integrated head and neck 1, shoulder 2 and body back 3, and forms two parts along its periphery at a certain distance. The circular installation hole 4 corresponding to the side, the center line of the shoulder 2 is formed longitudinally with a rectangular socket 13 with semicircular ends, which is equivalent to a hollowed out square grille 5 formed on the head and neck part 1.
[0022] An adapter frame for head, neck, shoulder and body radiotherapy positioning boards, the first horizontal strip 6, the second horizontal strip 7 and the third horizontal strip 8 parallel to each other are formed vertically and integrally at the midpoint and vertical strip 9 respe...

The invention discloses an adapter frame for a head, neck, shoulder and body radiotherapy positioning plate, and belongs to accessories for radiotherapy. Three parallel transverse battens are perpendicularly and integrally formed with a longitudinal batten at the midpoints respectively, the two ends of the third transverse batten are bent and extend to form bevel edge parts at obtuse angles in the same direction, the top side faces of the third transverse batten perpendicularly protrude at certain intervals to form corresponding top column tables, the ventral faces of the free ends of the bevel edge parts protrude to form cylindrical plugs respectively, and the ventral surface of the longitudinal batten close to the third transverse batten protrudes to form a rectangular plug with two semicircular ends. According to the design, the occipital, the neck and the back of a patient are restrained on the hardened and shaped shaping pad, an adapter frame groove is formed in the bottom face of the shaping pad, and the adapter frame for the head, neck, shoulder and body radiotherapy positioning plate is embedded into the groove and cannot move, so that patients with whole brain, whole spinal cord and long target region radiotherapy are not displaced due to micro movements, and the body position stability repeatability and the treatment accuracy of the patients in the treatment process are ensured. The positioning error in treatment is reduced, and the treatment effect of radiotherapy is improved.
Description
technical field [0001] The invention relates to an accessory used in radiotherapy, in particular to an adapter frame for a head, neck, shoulder and body radiotherapy positioning plate used in combination with a shaping pad for radiotherapy of head, neck, shoulder and body tumors. Background technique [0002] In the treatment of patients with whole brain, whole spinal cord and long target area radiotherapy, especially in the precise radiotherapy of malignant tumors, fixing the patient's body position can reduce the involuntary movement of the patient's body position during radiotherapy, thereby ensuring the actual irradiation range of the beam It is especially important to keep the radiotherapy position fixed as consistent as possible with the planned target area. [0003] At present, in order to ensure the precise treatment of patients with whole brain, whole spinal cord and long target area radiotherapy, and prevent dislocation caused by involuntary activities of patients,...
