ABSTRACT:
Methods are provided for surgical lavage including pumping liquid to bone and other tissue surfaces with a reciprocating pump mechanism operated by pressurized gas wherein pressurized exhaust gas is further utilized to accelerate the pulsed liquid. A first valve arrangement is provided to bypass the pumping mechanism to direct pressurized gas directly onto the tissue surface without the presence of liquid from the device. A second valve arrangement is provided for optionally venting at least a portion of the exhaust gas to the atmosphere instead of directing it to the tissue surface. An additive line delivers additive to the gas bypass line for delivery of the additive to the tissue surface with the flowing gas stream.
