Surgical device for the collection of soft tissue
First Claim
1. 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.

Abstract
A biopsy device comprises a handpiece, a fluid collection system, and a power transmission source. The handpiece is configured for grasping by a single hand, and is independently manipulatable by hand for movement of the instrument toward and away from the patient. An elongated piercer extends from the distal end of the handpiece. The piercer has a sharpened distal end for entering the tissue and a port located proximal to the sharpened distal end for receiving a portion of tissue mass. An elongated cutter is disposed coaxially relative to a piercer lumen of the piercer. A distal blade of the cutter slides distally past the port of the piercer to sever the tissue portion drawn into the port by vacuum. The handpiece further comprises a holster for detachably connecting a cutter rotational transmission and a cutter axial transmission to the power transmission source.

14. A biopsy device, comprising:
-
(a) a holster, wherein the holster comprises at least one motor; and (b) a probe assembly detachably coupled with the holster, wherein the probe assembly comprises; (i) an elongated piercer, the piercer having 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 relative to the port, wherein the at least one motor of the holster is operable to move the cutter relative to the piercer; wherein 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. - View Dependent Claims (15, 16, 17)

18. A biopsy device, comprising:
-
(a) a probe assembly, wherein the probe assembly comprises; (i) an elongated piercer, the piercer having a closed, sharpened distal end for piercing tissue and a transverse bowl proximal to the sharpened distal end for receiving a portion of a tissue mass, and (ii) an elongated cutter having an open 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 transverse bowl of the piercer when the cutter moves distally relative to the transverse bowl; and (b) a holster detachably coupled with the probe assembly, wherein the holster comprises at least one motor operable to move the cutter distally relative to the transverse bowl; wherein 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. - View Dependent Claims (19, 20)
