High speed pulse lavage surgical hand tool attachment
First Claim
1. A pulsed lavage attachment for a powered modular surgical hand piece, comprising:
- a housing;
a connector located at a first end of said housing, said connector being configured to fit within a coupler of a powered modular surgical hand piece;
an internal driver positioned within said connector for mating with an output driver of a powered modular surgical hand piece, said internal driver being axially rotatable;
a coupler located at a second end of said housing, said coupler being configured to receive a connector of a pulsed lavage fluid delivery set;
an actuator positioned within said coupler, said actuator being axially moveable within said coupler to interact with a connector of a pulsed lavage fluid delivery set; and
a drive mechanism which is connected to said internal driver in said connector and said actuator in said coupler which translates rotational drive power of said internal driver into axial movements of said actuator.

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.
