A biopsy device includes an outer cannula, an inner rod, a sheath operably associated with the outer cannula, a handle assembly removably attachable to the sheath, and a release member for releasably attaching the handle assembly to the sheath. In one embodiment, a locking element associated with the sheath comprises a pair of notches located on either side of the sheath, and a locking element associated with the handle assembly comprises a pair of slots in communication with an opening within the handle assembly. The release member comprises a rotatable collar located in a channel on the handle assembly. When the release member is rotated from a first position to a second position, a portion thereof protrudes through the slots into the notches on the sheath, thereby locking the sheath in place.
