Abstract

The invention discloses a human body auxiliary positioning device for radiotherapy and a three-dimensional treatment bed. The auxiliary positioning device includes a left positioning mechanism and a right positioning mechanism arranged oppositely, and the left positioning mechanism and the right positioning mechanism are installed on the treatment bed respectively. Both sides; the left side positioning mechanism and the right side positioning mechanism are all provided with a vertical plate, a movable plate, an arc positioning plate and an adjustment shaft, the bottom of the vertical plate and the side of the treatment bed are fixed by a connecting mechanism, and the front of the vertical plate top has a Strip-shaped opening, movable plate is installed in the strip-shaped opening, the shape of the movable plate matches the strip-shaped opening, strip-shaped through-grooves are opened on the upper side of the vertical plate and the side of the movable plate, and the adjustment shaft passes through the strip-shaped transparent slots of the vertical plate and the movable plate in turn. Positioning nuts are installed behind the groove, and the relative height of the movable plate on the vertical plate and the length that the movable plate stretches inward can be adjusted by adjusting the shaft. Through the auxiliary positioning device of the present invention, the patient's body position during radiotherapy can be accurately positioned, thereby achieving better and more precise tumor radiotherapy.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a human body auxiliary positioning device for radiotherapy and a three-dimensional treatment bed. Background technique [0002] Radiation therapy (Radiotherapy) is a treatment that uses radiation to irradiate malignant tumors to inhibit their growth and cause death, referred to as radiotherapy. The basic principle of radiotherapy is to destroy malignant tumors and preserve normal tissues. Ionizing radiation refers to electromagnetic waves or particles that can directly or indirectly produce ionizing effects in substances, which can be produced by artificially accelerating charged particles or by radionuclides. [0003] Radiation therapy began after the discovery of X-rays and radioactive substances. With the development of radiation physics, radiation biology, clinical oncology and various radiation therapy devices, it has become the three main means of treating malignant tumor...
