Tissue biopsy device with rotatably linked thumbwheel and tissue sample holder
First Claim
1. A biopsy device for acquiring tissue samples from a patient, the biopsy device comprising:
- a probe, comprising;
a needle portion having a tissue receiving aperture, wherein the needle portion defines a longitudinal axis,a body portion having a distal end and a proximal end, wherein the needle portion extends distally from the distal end of the body portion,a rotatable thumbwheel coupled with the needle portion, wherein the rotatable thumbwheel is fixedly secured relative to the needle portion such that the thumbwheel is operable to rotate the needle portion about the longitudinal axis,a cutter longitudinally movable within the needle portion, wherein the cutter is configured to cut tissue protruding into the aperture, wherein the cutter defines a cutter lumen, anda rotatable tissue sample holder configured to receive tissue samples severed by the cutter and communicated through the cutter lumen; and
a holster removably coupled with the probe, the holster comprising a linking mechanism, wherein the thumbwheel is rotatably coupled with the tissue sample holder via the linking mechanism such that the thumbwheel is manually rotatable to rotate the tissue sample holder via the linking mechanism.

Abstract
A biopsy device comprises a probe operably coupled with a holster. The probe comprises a needle portion, a body portion, a rotatable thumbwheel, a cutter, and a rotatable tissue sample holder. The needle portion has a tissue receiving aperture. The needle portion extends distally from the body portion. The thumbwheel is fixedly secured relative to the needle portion such that the thumbwheel is operable to rotate the needle portion about its longitudinal axis. The cutter is longitudinally movable within the needle portion and is configured to cut tissue protruding into the aperture. The rotatable tissue sample holder is configured to receive tissue samples severed by the cutter and communicated through the cutter lumen. The holster comprises a linking mechanism. The thumbwheel is coupled with the tissue sample holder via the linking mechanism such that the thumbwheel is manually rotatable to rotate the tissue sample holder via the linking mechanism.
