Problems solved by technology

[0002] Cobalt-60 therapy machines, blood irradiation machines and other radiation therapy machines use mobile radiation sources. The existing method is to rely on manual on-site operation, which causes serious radiation damage. In addition, due to the large weight of the source container itself, in order to reduce radiation damage, usually It is very inconvenient to align the moving channel when the source container and the treatment head are put together, and it can only be operated by experience, which has great potential safety hazards

Abstract

The invention relates to a radioactive source loading and pouring-out driving device of a radio therapeutic machine, which is used for moving a radioactive source. A guiding groove corresponding to a source channel in the radio therapeutic machine and a source drawer channel of a source pouring container is provided, and a push-pull rod which reciprocates is correspondingly arranged at one end of a source drawer. The source drawer can be conveniently moved to a preset position with the help of the guiding groove and through the push-pull rod so as to pour out and load the radioactive source and to lay a foundation for automatic control, therefore, the automatic control can be easily realized, to completely replace manual operation. The driving device is simple, convenient and accurate, and can be operated separately, and prevent operators from being damaged by rays. Furthermore, the driving device is safe and reliable.

Description

technical field [0001] The invention relates to a radiation source loading and unloading driving device of a radiotherapy machine, which is used for the movement of the radiation source. Background technique [0002] Cobalt-60 therapy machines, blood irradiation machines and other radiation therapy machines use mobile radiation sources. The existing method is to rely on manual on-site operation, which causes serious radiation damage. In addition, due to the heavy weight of the source container itself, in order to reduce radiation damage, usually It is very inconvenient to align the moving channel when the source container and the treatment head are put together, and it can only be operated by experience, which has great potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a radiotherapy machine radiation source loading and unloading driving device, which replaces manual operation, is simple, convenient and accurate...
