Special radiotherapy device for doctor

Abstract

The invention discloses a special radiotherapy device for a doctor and belongs to the technical field of medical devices. The device comprises a radiotherapy bed body mechanism, a ray machine mechanism and a control system. A human body center line marking device comprising a fixed locking piece, a moving locking piece and a center sheet plate is arranged on the radiotherapy be body. An infrared detector is arranged in the center of a ray outlet of the ray machine and is used for detecting a human body center line. An annular sleeve is arranged between the ray machine and a connection column so that the ray machine is allowed to face the lower part all the time. An infrared emitter is arranged at the joint of the communication column and a rotary disc. An annular infrared receiver is arranged at the center of the rotary disc so as to finish determination of the rotation angle of the emitter in an auxiliary manner. According to the invention, the radiation machine is enabled to be precisely aligned to the center line of the body of a patient; the distance between the radiation machine and the body of the patient is precisely adjusted to be a demand value; precise positioning of a radiotherapy part is conveniently carried out; and in the radiotherapy processes, the distance between the radiation machine and the body of the patient is kept to be the demand value.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiotherapy equipment dedicated to doctors. Background technique [0002] Radiotherapy is the medical term for radiation therapy, a localized treatment that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors. Radiotherapy can be used alone or in combination with surgery, chemotherapy, etc. as part of comprehensive treatment to improve the cure rate of cancer. As an important means of treating malignant tu...

Problems solved by technology

The disadvantage of existing radiotherapy equipment is that its transmitter is associated with the centerline of the radiotherapy bed, but when applied, it is difficult for the patient to lie in the middle of the radiotherapy bed accurately, that is, the centerline of the transmitter and the patient's body cannot be reached. Establishing a correlation makes it difficult to locate the radiotherapy site, and for the radiotherapy site that is symmetrical about the centerline of the body, there is no correlation and cannot be directly located. It needs to be re-detected and positioned, which affects the radiotherapy efficiency; on the other hand, the radiotherapy bed should be adjusted first. During radiotherapy, the height of the radiotherapy bed is constant, and the transmitter rotates, so that the radiation penetration distance cannot be kept stable, which will have a certain adverse effect on the radiotherapy effect
