Manually rotatable piercer
First Claim
Patent Images
1. A biopsy device comprising:
- an elongated piercer having a closed distal end, a proximal end, a lateral tissue receiving port spaced proximally of the distal end, and a cutter lumen, wherein the piercer is supported for rotation about a longitudinal axis of the elongated piercer; and
a hollow cutter adapted to rotate and translate within the cutter lumen to sever tissue received in the tissue receiving port;
wherein the elongated piercer is manually rotatable with respect to at least one other portion of the biopsy device from a position spaced proximally from the proximal end of the piercer.

Abstract
The present application is directed to an image-guided, vacuum assisted, percutaneous, coring, cable driven breast biopsy instrument which may be conveniently mounted to an x-ray machine wherein the biopsy instrument incorporates a rotation knob at the proximal end of the instrument to manually rotate the distal end of the probe, thus allowing the clinician to conveniently position the tissue port next to the tissue to be sampled.

15. A biopsy device comprising:
-
an elongated piercer having a closed distal end, a proximal end, a lateral tissue receiving port spaced proximally of the distal end, and a cutter lumen, wherein the piercer is supported for rotation about a longitudinal axis with respect to a stationary portion of the biopsy device; a hollow cutter adapted to rotate and translate within the cutter lumen to sever tissue received in the tissue receiving port; at least one fluid seal disposed in the biopsy device; wherein the elongated piercer is manually rotatable from a position proximal of the at least one fluid seal. - View Dependent Claims (16, 17)

18. A method of obtaining biopsy samples comprising the steps of:
-
obtaining a biopsy device comprising; a piercer extending from a distal end of the biopsy device, the piercer having a closed distal end and a lateral tissue receiving port spaced proximally of the distal end; and a hollow cutter adapted to rotate and translate within the piercer to sever tissue received in the lateral tissue receiving port; directing the piercer into a tissue mass; receiving tissue into the lateral tissue receiving port of the piercer; severing a tissue sample from the tissue received in the port with the cutter; transporting the first tissue sample through the piercer; and without removing the piercer from the tissue mass, manually rotating the piercer about a longitudinal axis of the piercer from a position associated with a proximal portion of the biopsy device spaced from a proximal end of the piercer. - View Dependent Claims (19, 20, 21, 22, 23)

24. A biopsy device comprising:
-
an elongated piercer having a closed distal end, a proximal end, a lateral tissue receiving port spaced proximally of the distal end, and a cutter lumen, wherein the piercer is supported for rotation about a longitudinal axis of the elongated piercer; a hollow cutter having an open end adapted to rotate and translate within the cutter lumen to sever tissue received in the tissue receiving port; a rotatable member, wherein at least a portion of the rotatable member extends proximally of the proximal end of the piercer, and wherein rotation of the rotatable member provides rotation of the piercer. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A biopsy device comprising:
-
an elongated piercer having a closed distal end, a proximal end, a lateral tissue receiving port spaced proximally of the distal end, and a cutter lumen, wherein the piercer is supported for rotation about a longitudinal axis of the elongated piercer; a hollow cutter having an open end adapted to rotate and translate within the cutter lumen to sever tissue received in the tissue receiving port; a manual rotation feature spaced proximally from the proximal end of the piercer; and a rotatable member extending through at least a portion of the biopsy device for transmitting rotational motion from the manual rotation feature to the piercer. - View Dependent Claims (32, 33, 34, 35, 36, 37)
