Description

Body position fixing device applied to radiotherapy of breast patient Technical Field The invention relates to the technical field of medical equipment, in particular to a radiotherapy auxiliary device, and especially relates to a body position fixing device applied to radiotherapy of a breast patient. Background Radiation therapy is one of the core therapeutic means in clinical diagnosis and treatment of malignant tumor and other diseases. In the radiation treatment of breast cancer, the patient is typically required to assume a supine position with both arms raised to fully expose the chest wall and breast area while reducing the exposure dose to the lungs and heart. The radiation exposure time for single radiation therapy is typically 15-30 minutes, however, the total procedure for the patient from entering the treatment room, completing the postural positioning, image-guided verification to the end of the treatment is typically 30 minutes to 1 hour. The actual time consumption is affected by multiple variables such as the anatomical location of the target region to be treated, the radiotherapy technique used (e.g., intensity modulated radiotherapy IMRT, volume rotational intensity modulated radiotherapy VMAT or stereotactic radiotherapy SBRT), the equipment performance, and the individual factors of the patient. During this process, the patient needs to maintain a highly repeatable and stable fixed position on the treatment couch. Maintaining a fixed posture for a long time is likely to cause muscle fatigue and joint discomfort of the patient, and further, autonomous displacement is generated, which affects the treatment accuracy. Thus, the reliability, comfort and anti-migration capabilities of the posture fixation device are critical to the accurate delivery of radiation therapy. In the prior art, a flat plate type or fixed arc-shaped supporting plate is usually adopted as a back support for the breast radiotherapy body position fixing device, the supporting surface is of a horizontal design or a single fixed inclination angle, the back support angle is single and is difficult to adapt to the requirements of patients with different body types, the arm support is of a simple plane supporting plate or semicircular tube structure, the height and the angle are fixed, the rotation linkage mechanism of the scapula and the forearm anatomy form during shoulder joint abduction are not considered, shoulder fatigue is easily caused by long-time support, the handle part is often absent or a fixed upright column design is adopted, the position and the height are not adjustable, and the difference of the upper arm length of 22 cm to 35cm of an adult cannot be adapted, so that the patient is difficult to maintain a stable posture. Disclosure of Invention The invention provides a body position fixing device applied to the radiotherapy of a breast patient, which can be used for solving the problem of discomfort caused by long-time body position maintenance of the patient in the existing supine position fixing treatment and improving the stability and the treatment accuracy of the body position. The invention relates to a body position fixing device applied to radiotherapy of breast patients, which comprises a lying pad detachably arranged on a CT bed board, wherein the lying pad comprises a horizontal plane opposite to a head and an inclined plane used for supporting the back of a human body and enabling the patient to be in a supine inclined position, a U-shaped arm support pad encircling the periphery of the head and a headrest arranged in an arm support pad surrounding area and used for supporting the head are detachably arranged on the horizontal plane of the lying pad, the opening direction of the arm support pad faces towards the neck, supporting inclined planes used for supporting the two arms of the patient to be in a lifting and abduction position are arranged on the two sides of the arm support pad, a plurality of mounting holes are formed in the two side edges adjacent to the U-shaped bottom edge of the arm support pad, and handles used for holding the patient by two hands to maintain the body position stable are detachably arranged in the mounting holes. The body position fixing device applied to the radiotherapy of the breast patient can change the lying pad with various inclination angle specifications according to the curvature and the body type difference of the spine of the patient through the detachable mounting mode of the lying pad and the CT bed board, enable the back of the human body to form a supine inclined body position by utilizing the inclined surface, attach to physiological curvature of the spine, reduce lumbar vertebra pressure, change the arm support pad with various thickness specifications according to the shoulder joint movement degree and the upper arm length of the patient through the detachable mounting mode of the arm support pad and the horizontal plane, enable the two arms to k
