Patent ID: 8206409

Claim:
A biopsy device, comprising: (a) a holster; (b) a probe assembly, the probe assembly being detachably coupled with the holster such that portions of the outer surfaces of the probe assembly and holster together define a handpiece shaped and configured for grasping by a single hand such that a portion of the outer surface of the probe assembly and a portion of the outer surface of the holster are both exposed for grasping simultaneously, wherein the probe assembly comprises: (i) an elongated piercer extending distally from the handpiece, the piercer having a piercer lumen, a closed, sharpened distal end for piercing tissue, and a port proximal to the sharpened distal end for receiving a portion of a tissue mass, and (ii) an elongated cutter having a distal end, a proximal end, and a cutter lumen therethrough, the cutter being disposed coaxially and slidably relative to the piercer, the cutter distal end being configured to cut a portion of tissue protruding into the port of the piercer when the cutter moves distally past the port; (c) a first motor disposed within the holster for providing motion of the elongated cutter; and (d) a second motor disposed within the holster for providing translation of the elongated cutter.
