Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , 2 , 3, in the present invention, the radiotherapy driving device includes: a shielding body 2, a source body 4, a radiation source 5, a source box 3, and a driving device for the source box 3, and the radiation source 5 is located in the source box 3, and the shielding body 2 and the source body 4 are provided with a space for accommodating the source box 3 , the driving device of the source box 3 is detachably installed under the source box 3 , and drives the source box 3 to move up and down between the shield body 2 and the source body 4 . There is a base 1 under the shielding body 2, and the center of the shielding body 2 and the base 1 is provided with a moving space for the source box 3 to rise and fall. The shielding body 2 and the base 1 are cast iron structures with internal cavities, and the cavities are filled with heavy m...

Abstract

The present invention relates to a radiotherapy driving device which includes: shield, source body, radioactive source, source deck, driving device of source deck. The radioactive source is in the source deck inner, the shield and source body have space for containing the source box, the driving device of the source box can be separated installed on down part of the source box, and the source box is drived to up-and-down movement between the shield and source box. The shield and source box are in the down part of the source body, which can save the shield material, reduce the whole device weight and occupied space; the driving device of the source box can be separated drive the source box up-and-down movement when treating, the source box is fixed on radiation device of the radiotherapy system by lock board, and rotary irradiate with the radiation device. The radiotherapy driving device reduces protective request of the radiation device, prevents motor block of the source box efficiently, simplifies the radiotherapy system structure, reduces processing difficuites and saves cost.

Description

technical field [0001] The invention relates to radiation medical equipment, in particular to a radiation source device for gamma ray radiation therapy. Background technique [0002] The gamma ray radiation therapy system uses cobalt-60 as the radiation source. When the radiation therapy system is used for radiation therapy, the radiation source beam in the source body rotates and focuses on the patient's lesion, and performs rotary irradiation; when the radiation therapy system is in non-treatment state, in order to shield the gamma rays released by the cobalt-60 radioactive source, the radioactive source is placed in the shielding body, and there is a shielding material of sufficient thickness around the radioactive source to ensure that the environment around the radiotherapy system is in a safe state; the radiotherapy equipment is from non- When the treatment state is switched to the treatment state, the radiation source enters the source body from the shielding body, re...
