    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.

    Abstract: A biopsy device includes an instrument set and an instrument drive unit removably coupled to the instrument set. The instrument set includes an instrument set housing; an elongate outer cannula having a tissue receiving aperture in a side wall thereof; an elongate inner cannula disposed within an outer cannula lumen; an aspiration vent fluidly coupling the outer cannula lumen to atmosphere; and an aspirate valve in the aspiration vent, and configured such that the outer cannula lumen is vented to atmosphere only when the aspirate valve is open. The instrument drive unit includes a drive unit support structure removably coupled to the instrument set housing; a motorized inner cannula driver configured to axially oscillate the inner cannula relative to the outer cannula to sever tissue extending through the tissue receiving opening; and an actuating member configured to selectively mechanically prevent the aspirate valve from closing.
