1. A biopsy system driver, comprising:
a support structure;
a motor secured to the support structure and comprising a rotatable motor output shaft;
a spline rotatably coupled to the support structure and operatively connected to the motor output shaft, wherein activation of the motor rotates the spline;
a drive shaft rotatably coupled to the support structure, wherein the drive shaft is operatively coupled to the spline, wherein rotation of the spline rotates the drive shaft;
an elongate lead screw axially-translatably coupled to the drive shaft, wherein rotation of the drive shaft rotates the lead screw about an axis of the lead screw, wherein the lead screw is axially translatable relative to the drive shaft between a proximal position and a distal position; and
a biopsy instrument drive member comprising a biopsy needle engagement element to operatively couple the biopsy instrument drive member to at least a portion of a biopsy needle, wherein the biopsy instrument drive member is movably coupled to the lead screw between a first position and a second position,
wherein when the lead screw is in the distal position and the biopsy instrument drive member is in the first position, rotation of the lead screw in a first lead screw rotational direction causes axial translation of the biopsy instrument drive member towards the second position, and
wherein when the lead screw is in the distal position and the biopsy instrument drive member is in the second position, rotation of the lead screw in the first lead screw rotational direction causes axial translation of the lead screw towards the proximal position.
