Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
A biopsy instrument comprising: a base assembly including a firing mechanism moveably attached to a distal end of said base assembly; a probe assembly detachably mounted to said base assembly, said probe assembly comprising: a piercer assembly comprising: a piercer comprising; a distal port; a vacuum lumen; a cutter lumen; a first gear mechanism affixed to a proximal end of said piercer; a probe mount supporting said piercer; a cutter assembly detachably affixed to said base assembly, said cutter assembly comprising; a cutter adapted to move through said cutter lumen; an adjustment wheel extending from a proximal end of said cutter assembly; a drive rod connected to said adjustment wheel said drive rod being operatively connected to said first gear mechanism; a drive assembly detachably mounted to said cutter assembly, said drive assembly including a flexible drive shaft operatively connected to said cutter.
Claim 2
Dependent Claim
143 words
A biopsy instrument comprising: a base assembly including a firing mechanism moveably attached to a distal end of said base assembly; a probe assembly detachably mounted to said base assembly, said probe assembly comprising: a piercer assembly comprising: a piercer comprising; a distal port; a vacuum lumen; a cutter lumen; a first gear mechanism affixed to a proximal end of said piercer; a probe mount supporting said piercer; a cutter assembly detachably affixed to said base assembly, said cutter assembly comprising; a cutter adapted to move through said cutter lumen; an adjustment wheel extending from a proximal end of said cutter assembly; a drive rod connected to said adjustment wheel said drive rod being operatively connected to said first gear mechanism; a drive assembly detachably mounted to said cutter assembly, said drive assembly including a flexible drive shaft operatively connected to said cutter.
Claim 3
Dependent Claim
206 words
A biopsy instrument comprising: a base assembly including a firing mechanism moveably attached to a distal end of said base assembly; a probe assembly moveably attached to said base assembly, said probe assembly comprising: a piercer assembly comprising: a piercer moveable from a proximal position to a distal position comprising: a distal port; a vacuum port; a cutter lumen; a first gear affixed to a proximal end of said piercer; a probe mount supporting said piercer wherein said probe mount comprises: a second gear affixed to a drive shaft, said second gear meshing with said first gear; a fork coupling detachably mountable to said firing mechanism; a cutter assembly detachably affixed to said base assembly, said cutter assembly comprising: a cutter adapted to move through said cutter lumen an adjustment wheel extending from a proximal end of said cutter assembly; a drive rod connected to said adjustment wheel, said drive rod being slideably affixed to a proximal end of said drive shaft such that rotation of said adjustment wheel rotates said piercer as said piercer moves from said proximal position to said distal position; a drive assembly detachably mounted to said cutter assembly, said drive assembly including a flexible drive shaft operatively connected to said cutter.
Claim 4
Dependent Claim
206 words
A biopsy instrument comprising: a base assembly including a firing mechanism moveably attached to a distal end of said base assembly; a probe assembly moveably attached to said base assembly, said probe assembly comprising: a piercer assembly comprising: a piercer moveable from a proximal position to a distal position comprising: a distal port; a vacuum port; a cutter lumen; a first gear affixed to a proximal end of said piercer; a probe mount supporting said piercer wherein said probe mount comprises: a second gear affixed to a drive shaft, said second gear meshing with said first gear; a fork coupling detachably mountable to said firing mechanism; a cutter assembly detachably affixed to said base assembly, said cutter assembly comprising: a cutter adapted to move through said cutter lumen an adjustment wheel extending from a proximal end of said cutter assembly; a drive rod connected to said adjustment wheel, said drive rod being slideably affixed to a proximal end of said drive shaft such that rotation of said adjustment wheel rotates said piercer as said piercer moves from said proximal position to said distal position; a drive assembly detachably mounted to said cutter assembly, said drive assembly including a flexible drive shaft operatively connected to said cutter.
