Abstract
A motorized stand for positioning medical therapeutic or diagnostic instruments is mechanically coarsely balanced by weights. A defined positioning of the medical instrument is determined by means of several drive units with integrated angle transducers. Operating safety is additionally ensured, in the event of failure of a drive unit, by the use of two angle transducers per drive unit. One angle transducer is coupled to the drive motor of each drive unit. The other angle transducer is independent of the drive motor.
