Abstract
A drive system is provided for rotating a biopsy member. The drive system includes a pinion connected to the biopsy member and a rack that drives the pinion during a drive stroke. During the return stroke, the rack rotates away from the pinion so that the rack is not engaged with the pinion during the return stroke. Thus, the pinion is only driven during the drive stroke but not during the return stroke. As a result, the biopsy member rotates in a single direction as a trigger is repeatedly pressed and released.
