Abstract:
1. A biopsy device, comprising: a probe cannula defining an internal passage; a proximal portion attached to the probe cannula positionable to insert the probe cannula into tissue; a cutter reciprocally received by the probe cannula to sever a tissue sample received in the probe cannula; a pneumatic container attached with the proximal portion and operably configured to communicate a low pneumatic pressure contained within the pneumatic container with the probe cannula; a motor contained in the proximal portion operatively coupled to translate the cutter, wherein the motor is further operatively coupled to reduce pneumatic pressure in the pneumatic container; and a frame assembly positioned within the biopsy device adjacent the proximal portion and attached to the probe cannula, wherein the frame assembly is longitudinally movable within the biopsy device, wherein the motor is further operably configured to impart a longitudinal reciprocating motion to the frame assembly during insertion of the probe cannula into tissue.
