Problems solved by technology

However, the existing body position fixation devices are relatively complicated to use, and usually need to be implemented according to the actual height and body shape of the patient, which increases the labor of medical staff; the versatility is poor, and even if the position of the same patient is placed, it lacks accurate positioning. Poor positioning repeatability

Abstract

The invention discloses a radiotherapy positioning device and a radiotherapy device. The radiotherapy positioning device comprises a base. A fixing mechanism is arranged in the center of the top surface of the base. Baffles are fixedly connected to the two sides of the top face of the base correspondingly. A positioning mechanism is arranged on the top surfaces of the baffles. The positioning mechanism comprises two screw rods and an arc-shaped guide rail. Transmission seats are fixedly connected to the two ends of the top face of each baffle correspondingly. The side faces, located on the same side of the two baffles, of the two transmission seats are fixedly connected with transmission motors correspondingly. The two ends of the arc-shaped guide rail are fixedly connected with the top surfaces of two shaft sleeves respectively. One side surface of the arc-shaped guide rail is fixedly connected with an arc-shaped rack. The arc-shaped guide rail is sleeved with a radiotherapy mechanism. One side of the positioning plate is in sliding connection with the other side of the arc-shaped guide rail. A guide wheel assembly and a transmission gear are arranged on the other side of the positioning plate. A transmission shaft is fixedly connected to the side face of the transmission gear. The other end of the transmission shaft is in transmission connection with a positioning motor. A radiotherapy assembly is arranged at the bottom of the positioning plate.

Description

technical field [0001] The invention relates to the technical field of radiotherapy, in particular to a radiotherapy positioning device and a radiotherapy device. Background technique [0002] Radiation therapy 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] At present, when clinically performing radiotherapy to patients, it is necessary to use body position fixation devices to fix various parts of the patient's body to prevent the irradiated parts from moving during irradiation, thereby reducing the irradiation dose to normal tissues and ensuring that the target ...
