Apparatus for extracting bone material from an extraction site using a vacuum source. The apparatus comprises a needle having a proximal end adapted for fluid communication with the vacuum source and a distal end. The needle has an interior surface defining a passageway extending from the proximal end to the distal end. An abrading member is disposed in the needle passageway, and an actuator is operably coupled to the abrading member.
