Abstract:
A biopsy device for the collection and retrieval of at least one soft tissue portion from a surgical patient, said biopsy device comprising:a. a handpiece configured for grasping by a single hand, said handpiece having a distal end and a proximal end, said handpiece being independently manipulatable by the single hand without an external support for movement of said biopsy device toward and away from the surgical patient;b. an elongated piercer extending from the distal end of said handpiece, said piercer havingi. a piercer lumen,ii. a sharpened distal end for entering tissue when said handpiece of said biopsy device is moved independently by the single hand toward the surgical patient so as to cause said sharpened distal end to penetrate the tissue, andiii. a port located proximal to said sharpened distal end for receiving a portion of a tissue mass when said handpiece is further manipulated independently by the single hand so as to position the tissue mass adjacent to said port, said piercer lumen being in fluid communication with said port;c. an elongated cutter having a distal end, a proximal end, and a cutter lumen therethrough, said cutter being disposed coaxially and slidably relative to said piercer, said cutter having a cutting blade on the cutter distal end for cutting the portion of tissue protruding into said port of said piercer when said cutter slides distally past said port, thereby depositing the portion of cut tissue within said cutter lumen of said cutter proximal to said cutting blade;d. a cutter rotational transmission contained within said handpiece and operationally connected to said elongated cutter, and when said cutter rotational transmission is actuated, said cutter is rotated about its longitudinal axis;e. a cutter axial transmission contained within said handpiece and operationally connected to said elongated cutter, and when said cutter axial transmission is actuated, said cutter is slid in an axial direction relative to said piercer; andf. a power transmission source connected to the proximal end of said handpiece and operationally engageable with:i. said cutter rotational transmission for actuating said cutter rotational transmission, andii. said cutter axial transmission for actuating said cutter axial transmission.
