Abstract
A biopsy system driver includes a motor having a rotatable output shaft, a support structure, a drive shaft, an elongate lead screw and a biopsy instrument drive member. The drive shaft is rotatably coupled to the support structure and includes or is otherwise operatively connected to the motor output shaft such that activation of the motor rotates the drive shaft. The elongate lead screw is coupled to the drive shaft such that rotation of the drive shaft rotates the lead screw about an axis of the lead screw. The lead screw is axially translatable relative to the drive shaft and to the support structure. The biopsy instrument drive member is threadably coupled to the lead screw such that rotation of the lead screw causes axial translation of one of the lead screw and biopsy instrument drive member relative to the other one and to the support structure.
