Body frame bed, moving mechanism and tumor local radiotherapy equipment

Abstract

The invention relates to a medical device, in particular to a body frame bed, a moving mechanism and tumor local radiotherapy equipment, and the body frame bed comprises a supporting table and a body frame bed movably arranged on the supporting table; the movable mechanism is mounted on the bracket and comprises a sliding rail fixed below the bracket and a mounting part slidably arranged on the sliding rail; a power assembly connected with the body frame bed is arranged on the mounting piece, and the mounting piece is connected with the bracket through a limiting assembly; the tumor local radiotherapy equipment comprises a suspended swinging piece which is rotationally connected with the bracket through a connecting shaft, and a linear accelerator is mounted on the suspended swinging piece; an angle adjusting mechanism is further arranged between the connecting shaft and the suspended swinging piece, and the driver is connected with the angle adjusting mechanism through the swinging assembly. The driver can drive the rotating member and the follower to rotate at the same time, and the follower and the rotating member are respectively provided with the grooved wheel and the positioning member which are adjustable in position, so that the whole radiotherapy equipment can treat a large-area focus.

Description

technical field [0001] The invention relates to a medical device, in particular to a frame bed, a movable mechanism and local radiotherapy equipment for tumors. Background technique [0002] Tumor is a new organism formed by the body under the action of various carcinogenic factors when a certain cell in a local tissue loses its normal regulation of its growth at the gene level, resulting in abnormal clonal proliferation. [0003] The current treatment methods for tumors include surgical resection, chemical targeted therapy, and radiation therapy; among them, radiation therapy is referred to as radiotherapy, and the most important therapy for radiotherapy is external radiation therapy, also called external radiation therapy. The radiation source is placed outside the human body. A method in which a linear accelerator irradiates high-energy rays or particle beams through the tumor target area. [0004] Radiotherapy is suitable for patients with early stage disease, and the l...

Problems solved by technology

[0004] Radiotherapy is suitable for patients with early stage disease, and the lesions are concentrated in a certain part. Radiotherapy can relieve the symptoms of the patient's condition and improve the quality of life of the patient. At present, most of the existing radiotherapy machines can only rotate around the body frame, and their irradiation range is very limited, requiring the patient to adjust the body position Cooperate with the machine, but the machine cannot actively cooperate with the patient's adjustment. It is very inconvenient for the patient suffering from pain to support the difficult position for a long time to cooperate with the machine. Therefore, it is necessary to develop a radiotherapy equipment that can be flexibly adjusted in multiple directions to actively cooperate with the patient and can adapt to the patient.
