摘要: Soft tissue biopsy apparatus (10) for obtaining a specimen. An elongate housing (12) has an opening (20) at one end (14). A hollow cannula (26) is positioned within the housing, reciprocally movable therewithin, and (28) of needle extends through insertion into (T) from which specimen to be taken.
