Abstract
A device comprises a needle, probe, holster, and tissue collection chamber. A motor simultaneously powers a vacuum pump, translates and rotates a cutter, and translates a plunger. The needle includes a piercing tip and an interior shelf that divides the needle into a cutter lumen and lateral lumen. The cutter and shelf include apertures configured to mince a portion of a tissue specimen that has been severed by the cutter and forced through the apertures by compressive force from the plunger as well as vacuum force. The apertures of the shelf and the apertures of the rotating cutter cooperate to shear the tissue being compressed by the plunger. The minced tissue is then transported to the tissue collection chamber under vacuum force with the assistance of a fluid flush. Collected minced tissue may then be further processed as desired for a given medical treatment or procedure.
