Abstract
A biopsy apparatus includes a cannula assembly having a cannula hub and a cutting cannula. A stylet assembly has a stylet hub and a stylet. The stylet is coaxial with the cutting cannula. An operator mechanism is configured to effect axial movement of the stylet hub and the cannula hub. The operator mechanism has a head portion configured to releasably engage the stylet hub and an arm member configured to releasably engage the cannula hub. The stylet hub is configured to be rotationally movable between an engaged position and a disengaged position, wherein in the engaged position the stylet hub is releasably connected to the head portion of the operator mechanism, and in the disengaged position, the stylet hub is disconnected from the head portion of the operator mechanism to facilitate axial movement of the stylet assembly in a proximal direction independent of the operator mechanism.
