Novel abdominal radiotherapy fixing frame special for radiotherapy department

Abstract

The invention discloses a novel abdominal radiotherapy fixing frame special for the radiotherapy department. The novel abdominal radiotherapy fixing frame comprises a bed body, bedding and a fixing assembly. The bedding is arranged on the top surface of the bed body; the fixing assembly comprises a first side plate and a second side plate which are symmetrically and slidably connected to the top faces of the two sides of the bed body, and a top plate is slidably connected between the first side plate and the second side plate. Positioning film holes are formed in the first side plate and the second side plate respectively, and the two positioning film holes correspond to each other and are used for fixing an abdomen positioning film; pressure fixing devices are fixed to the inner ends of the two sides of the top plate and used for fixing the abdomen of a patient. A radiotherapy hole is formed in the upper end of the top plate in a hollowed-out mode, and radiotherapy rays can pass through the radiotherapy hole. The device is simple in structure, convenient to use, flexible to adjust, suitable for patients of different body types, high in applicability and capable of effectively fixing the patients, preventing the patients from actively or inactively moving in the radiotherapy process and effectively improving the radiotherapy precision.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel abdominal radiotherapy fixation frame dedicated to the radiotherapy department. Background technique [0002] Radiation therapy, that is, radiotherapy, is a local treatment method that uses radiation to treat tumors; radiation includes α, β, and γ rays produced by radioisotopes and x-rays, electron beams, proton beams and x-rays produced by various x-ray therapy machines or accelerators Other particle beams, etc.; about 70% of cancer patients need radiotherapy in the process of cancer treatment, and about 40% of cancers can be cured with radiotherapy. Therefore, the role and status of radiotherapy in tumor treatment are becoming more and more prominent. One of the main means of malignant tumors. The radiotherapy cycle is basically about 30 days, and the usual treatment requires 25 to 30 times of radiotherapy, 5 to 6 times a week; in the process of radiotherapy, b...

Problems solved by technology

[0003] However, when radiotherapy is performed on the patient's chest and abdomen, the patient will breathe, and the patient's breathing will cause the patient's body to fluctuate to a certain extent. If the patient's voluntary or involuntary movement will cause greater changes in the treatment position, the irradiation area will be unstable. , affecting the effect of radiotherapy

[0004] The current fixed frame for abdominal radiotherapy is a simple support plate without a limiting device for restricting the movement of the patient. Although the positioning body film is based on the deformation of the patient's body shape and can restrict the patient's movement, the positioning body film is buckled on the patient's body, positioning The edge of the body membrane is fixed on the surface of the fixing frame with bolts or other fixing devices. If the connection between the positioning body membrane and the fixing frame is loose, the patient can still drive the positioning body membrane to move or twist, which will affect the effect of radiotherapy
