Abstract

The invention discloses a reductant power supply device of a gamma knife treatment bed collimator drive shaft, comprising a collimator driver mechanism, wherein the collimator driver mechanism is provided with a drive motor which is connected with two independent power supplies respectively via a driver; the driver is connected with a gamma knife treatment bed control bus; any power supply is connected with a power supply state detection circuit connected with the gamma knife treatment bed control bus; and the control bus is connected with an alarm device. The invention adopts a reductant power supply consisting of two power supplies to supply power for a collimator drive shaft, and the other power supply can continue to supply power for the collimator driver mechanism when any one power supply is in failure. The power supply state detection circuit can detect the states of two power supplies in real time, and when any one power supply is in failure, the control bus alarms. The invention can effectively prevent power failure of the collimator drive shaft in the treatment process, and avoid getting out of control of the gamma rays.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to radiotherapy equipment, in particular to a Gamma Knife, and in particular to a redundant power supply device for a collimator drive shaft of a Gamma Knife treatment bed. Background technique: [0002] In the prior art, during Gamma Knife treatment, the treatment head is rotated to a proper position, and then the radiation source is turned on for a predetermined time to irradiate. The radiation source is aimed at the treatment site through the collimator arranged on the turntable. After the treatment, the turntable is driven by the collimator drive shaft, and the collimator leaves the treatment site. In the event of a power failure, the collimator drive shaft loses power, the collimator stays in its current position, and the patient continues to be exposed to gamma rays, causing radiation damage. Invention content: [0003] The purpose of the present invention is to provide a redundant ...
