Biopsy device with selectable tissue receiving aperature orientation and site illumination

A biopsy device, comprising:

• a disposable elongated probe component including:
• an elongated tubular section which has a longitudinal axis, which has an inner lumen extending therein, which has a penetrating distal tip and which has a tissue receiving aperture proximal to the penetrating distal tip configured to receive tissue from the target site,
• a first driven gear coupled to the elongated tubular section and configured to rotate, the first driven gear configured to in turn rotate the elongated tubular section around the longitudinal axis,
• an elongated tissue cutting member which is disposed within the elongated tubular section, which has a distal end having at least one tissue cutting edge and which has an inner lumen extending therein, the elongated tissue cutting member having a proximal end opposite the distal end, and
• a second driven gear coupled to the elongated tissue cutting member and configured to rotate to longitudinally move the elongated tissue cutting member relative to the elongated tubular section along the longitudinal axis,
• the first driven gear and the second driven gear being arranged coaxially and adjacent each other on the longitudinal axis;
• and
• a driver component configured to receive a proximal portion of the disposable elongated probe component in an operational relationship, the driver component having:
• a first driver unit configured to rotate the elongated tubular section of the disposable elongated probe component to orient the tissue receiving aperture of the elongated tubular section, the first driver unit having a first drive gear, and
• a second driver unit configured to drive the elongated tissue cutting member longitudinally within the elongated tubular section to cut a tissue specimen from the tissue received in the tissue receiving aperture of the elongated tubular section, the second driver unit having a second drive gear positioned adjacent the first drive gear,
• the first drive gear and the second drive gear of the driver component configured to respectively drivably engage the first driven gear and the second driven gear that are arranged coaxially and adjacent to each other on the longitudinal axis.
