Abstract:
1. An apparatus suitable for cleaning a surgically prepared working surface by lavage with a pressurized fluid or fluid admixture from a pressurized fluid supply, and to aspirate fluids and debris dislodged from the surface, said apparatus comprising: a head adapted to deliver pressurized fluid toward the surgically prepared working surface at an angle substantially perpendicular to said surface to dislodge debris there when said head portion is in contact with the surgically prepared working surface, said dislodged surface debris being expelled through a collection channel; said head having a cleaning orifice adapted to engage with the working surface; wherein said head includes a primary fluid flow circuit arranged to flood and clean the working surface with said pressurized fluid, and an auxiliary fluid flow circuit arranged to produce or augment a pressure gradient across said working surface when said cleaning orifice is engaged with said working surface such that said pressurized fluid is constrained to flow substantially across said surface; and wherein said primary fluid flow circuit comprises:
