Device for radiotherapy

Abstract

The invention discloses a device for radiotherapy. The device comprises a handheld end. The handheld end comprises an outer wall, a hollow cavity arranged in the outer wall and a coiling device. The coiling device comprises a hand rubbing wheel and a coiling wheel. Each group of the hand rubbing wheel and the coiling wheel coaxially form a connection group which is matched with a hollowed hole in the outer wall of the handheld end. A hollow guide pipe ball head is arranged on one end, away from the handheld end, of a guide pipe, and is connected with a joint device. A protection sleeve is arranged on the outer side of the joint device which is connected with a radiation bin. The radiation bin cooperates with a radiation source. According to the invention, it is achieved that radiation in different angles and different distances can be performed on focuses of a patient; radiation regions are allowed to be quite precise; and damages to normal tissues in the patient body are reduced.

Description

technical field [0001] The invention relates to a radiotherapy device. Background technique [0002] Radiation therapy is a treatment method that irradiates the lesion with the help of α, β, γ and other high-energy particle flows released by the radioactive source, resulting in the apoptosis of the diseased cells. Existing radiotherapy mainly uses β and γ rays, and more γ rays are used. Because of the strong penetrating power of radiation, it is mostly carried out in a closed radiotherapy room. Facing a strange and cold treatment environment, it will bring psychological stress to the patient. It causes great pressure, which is not in line with the original intention of people-oriented treatment; at the same time, the existing brachytherapy, the radioactive source placed in the tissue often cannot adjust the posture and position, when faced with different tissue shapes and tumor locations, often The position of the radiation source cannot be adjusted according to the specifi...

Problems solved by technology

Existing radiotherapy mainly uses β and γ rays, and more γ rays are used. Because of the strong penetrating power of radiation, it is mostly carried out in a closed radiotherapy room. Facing a strange and cold treatment environment, it will bring psychological stress to the patient. It causes great pressure, which is not in line with the original intention of people-oriented treatment; at the same time, the existing brachytherapy, the radioactive source placed in the tissue often cannot adjust the posture and position, when faced with different tissue shapes and tumor locations, often The position of the radiation source cannot be adjusted according to the specific situation. Affected by the inverse square law of distance, in intracavitary tissue brachytherapy, the dose to the tissue near the radiation source is quite high, and the dose to the tissue far away from the radiation source is relatively low. , so the uniformity of the dose distribution in the target area is poor, and even the teletherapy with posture adjustment by means of radiation equipment also has the problem of poor uniformity of irradiation
