Abstract
A biopsy driver assembly includes a biopsy driver housing. An electrical assembly is coupled to the biopsy driver housing. The electrical assembly includes at least one electrical drive configured for drivably engaging a biopsy probe assembly. A battery is coupled to the biopsy driver housing. A control circuit is coupled to the biopsy driver housing. The control circuit is electrically coupled to the battery and to the electrical assembly. The control circuit has a motion detector, a timer circuit and a battery dwell circuit. The control circuit is configured to conserve the battery by providing electrical power only to the motion detector after a predetermined time following a last detected physical movement of the biopsy driver assembly and to provide electrical power from the battery also to the electrical assembly when a physical movement of the biopsy driver assembly is detected.
