1. A biopsy instrument comprising:
- a piercer comprising a proximal end, a tissue piercing distal end, a distal tissue receiving port spaced proximally of the tissue piercing distal end, and a cutter lumen;
a cutter adapted to rotate and translate within the cutter lumen of the piercer;
a firing mechanism for firing the piercer into tissue; and
an adjustment mechanism for adjusting the angular position of the distal tissue receiving port when the piercer is disposed in tissue, wherein the mechanism comprises an adjustment member that is manually operable at a position spaced proximally from the proximal end of the piercer, wherein the adjustment member is in mechanical communication with 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.

13. A biopsy instrument comprising:
-
a piercer comprising a proximal end, a tissue piercing distal end, a tissue receiving port spaced proximally of the tissue piercing distal end, and a cutter lumen; a cutter adapted to rotate and translate within the cutter lumen; a firing mechanism for firing the piercer into tissue; and means for adjusting the angular position of the distal tissue receiving port from a position spaced proximally from the proximal end of the piercer, wherein the means for adjusting the angular position of the distal tissue receiving port comprises an engagement member configured to selectively mechanically engage with the piercer, wherein the engagement member is further configured to selectively mechanically disengage with the piercer. - View Dependent Claims (14, 15, 16, 17)
