摘要： A bone cleaning and drying system for cleaning drying and emptying bones during joint replacement surgery, which includes an applicator for applying compressed gas, namely carbon dioxide, to the intramedullary canal and the cancellous bone, with an applicator nozzle at the distal end, the applicator nozzle having a plurality of end discharge slits and a plurality of angled side discharge slits to provide reverse flow, which provides a pressure gradient from the distal end to the proximal end, which aspirates and directs the entrained air, blood, fluids, fat, marrow, tissue and bone debris onto a drape or a hollow deflector shield surrounding the applicator, the front surface of the hollow deflector shield being apertured to allow the entrained materials to pass therethrough, the interior of the hollow deflector shield being connected to a flexible suction hose, and replaces room air with carbon dioxide in bone.
