An apparatus suitable for cleaning a surgically prepared working surface comprises a body portion adapted to supply pressurized fluid (preferably carbon dioxide gas) to the surgically prepared working surface and aspirate surface debris dislodged from the surgically prepared working surface. The apparatus further comprises ahead portion adapted to constrain the supplied pressurized fluid to flow substantially along the surgically prepared working surface to dislodge debris there from when the head portion is in contact with the surgically prepared working surface. The dislodged surface debris are aspirated by the body portion.
