1. A biopsy device, the biopsy device comprising:
(a) a probe having a probe housing;
(b) a needle extending from the probe;
(c) a cutter disposed within the needle, wherein the cutter defines a cutter lumen and at least partially defines a vent lumen between an exterior of the cutter and an interior of the needle; and
(d) a manually actuated needle rotation assembly including a pinion shaft, wherein a portion of the pinion shaft is exposed relative to the probe housing such that the pinion shaft is configured for actuation using a single hand while grasping the biopsy device with the single hand, the needle rotation assembly including a locking protrusion configured to selectively lock rotation of the pinion shaft, the pinion shaft being configured to move proximally relative to the locking protrusion to disengage the locking protrusion and thereby rotate relative to the locking protrusion.
