Description

Novel 3D prints neck elbow arm bracket

Technical Field

The utility model relates to a novel 3D prints neck elbow arm bracket.

Background

1. Conformal Intensity Modulated Radiation Therapy (IMRT) is a high-precision radiation therapy, and accurate postural fixation is the fundamental condition for the implementation of conformal intensity modulated radiation therapy. (IMRT) must meet the clinical dosimetry guidelines for tumors: (1) the tumor dosage is required to be accurate; (2) in the treated tumor region, the dose distribution is uniform, the dose variation gradient cannot exceed plus or minus 5 percent, even the dose distribution of more than 90 percent is achieved; (3) the irradiation field design should improve the dose in the treatment area as much as possible and reduce the irradiation dose range of the normal tissues in the irradiation area; (4) the vital organs surrounding the tumor are protected from irradiation. The fixation of the patient position during the radiotherapy also meets the requirements of conformal intensity modulated radiotherapy Quality Assurance (QA) and Quality Control (QC): not only must guarantee and control various errors in tumor radiotherapy technology: (1) positioning errors in fractionated treatment of tumors (breast cancer, lung cancer, etc.); (2) target area displacement and deformation error among different fractions; (3) the target area motion of the chest organs (lung, mammary gland, etc.) affected by the respiratory motion in the same treatment, etc.

2. Due to the particularity and irregularity of the curved surface shapes of the mammary gland and the chest wall, and the large volume of the breast cancer radiotherapy target area (the whole mammary gland, the chest wall, the upper part and the lower part of the clavicle, the axillary region and the like), the irregular shape and the large change of the surface curvature mean that the target area is more complicated and is greatly influenced by respiratory motion, so that various errors generated by the position fixation of the radiotherapy body are more. If no ideal accurate body position fixing mode exists or only the simple and crude head and neck or neck and chest thermoplastic films sold on the market are singly used as auxiliary products for body position fixing, the QA and QC requirements of tumor radiotherapy are far less met. As a result, the overall radiotherapy target volume is displaced, so that the dose of the target volume is low or the target volume is unevenly distributed, and the adverse phenomena of tumor recurrence after radiotherapy and the like occur.

3. Various radiotherapy posture fixing modes which are generally adopted clinically at present have certain defects. The main expression is in three aspects: firstly, the mammary gland and the chest wall are curved surfaces and have large mobility, the posture fixing repeatability before fractionated radiotherapy is poor, and a plurality of radiotherapy units in China currently only use a mammary gland bracket to fix the posture, and no standard fixing technology exists. Secondly, although the positioning precision is improved by using a mammary gland bracket, a head neck and/or neck and chest heat-shrinkable film and simultaneously fixing the body position as a main mode at present, the economic burden of a patient is increased, and due to the fact that the special body position of breast cancer radiotherapy, namely the activity of shoulder and elbow parts, is large, the ideal positioning and fixing precision cannot be achieved by using the heat-shrinkable film, the individuation degree is low, and the auxiliary positioning precision and various requirements of special pathological changes cannot be met; thirdly, the repeatability is poor, and the precision between the treatments can not be ensured. Therefore, the radiotherapy dosage of the tumor has great uncertainty to influence the curative effect.
