ABSTRACT:
A pulsed lavage attachment (40) is secured to a conventional, powered, modular, surgical hand piece (42) to allow a pulsed lavage delivery set (18) to be connected to and controlled by the hand piece (42), thereby eliminating the need for dedicated air or power lines and a dedicated pulsed lavage hand piece in the operating room. The pulsed lavage attachment (40) includes an internal driver (52) which mates with an output driver of the hand piece (42) and is axially rotatable by the output driver. A cam driver (56) connected to the internal driver (52) by pegs or other suitable means, and is rotatable therewith, has a cammed surface (62). A bearing member (64) rides on the cammed surface (62), and drives shaft (66) in an axial direction. Membrane (68) flexes outward to actuate a connecter (24) of the pulsed lavage delivery set (18) to actuate an internal pumping cartridge therein.
