Tissue biopsy device with selectively rotatably linked thumbwheel and tissue sample holder

A biopsy system comprising:

• (a) a probe assembly, wherein the probe assembly comprises a probe body, a needle, and a thumbwheel, wherein the needle is rotatable about a longitudinal axis;
• (b) a holster, wherein the holster is selectably attachable to the probe body, wherein the holster is configured to communicate with the thumbwheel when coupled to the probe body;
• (c) a tissue sample holder, wherein the tissue sample holder comprises a rotatable member comprising a plurality of chambers;
• and
• (d) a linking mechanism, wherein the linking mechanism is configured to communicate rotation of the thumbwheel to rotation of the rotatable member of the tissue sample holder, wherein the linking mechanism comprises a selective engagement mechanism, wherein the selective engagement mechanism is configured to selectably transition the linking mechanism between a first configuration and a second configuration, wherein the linking mechanism is configured to associate rotation of the thumbwheel with rotation of the rotatable member of the tissue sample holder when in the first configuration, wherein the linking mechanism is configured to disassociate rotation of the thumbwheel with rotation of the rotatable member of the tissue sample holder when in the second configuration.

A biopsy system comprising:

• (a) a body;
• (b) a needle extending distally from the body;
• (c) a thumbwheel associated with the needle, wherein the thumbwheel is configured to rotate the needle about a longitudinal axis;
• (d) a tissue sample holder comprising a rotatable member;
• and
• (e) a selective engagement mechanism, wherein the selective engagement mechanism is configured to selectively engage and disengage communication of rotation between the thumbwheel and the rotatable member of the tissue sample holder.

A biopsy system comprising:

• (a) a body;
• (b) a needle extending distally from the body;
• (c) a thumbwheel associated with the needle, wherein the thumbwheel is configured to rotate the needle about a longitudinal axis;
• (d) a tissue sample holder comprising a rotatable member;
• and
• (e) a motor, wherein the motor is configured to selectively coupled to the tissue sample holder and the needle, wherein the motor is configured to selectively decouple from the tissue sample holder to thereby only rotate the needle.
