ABSTRACT:
The surgical saw blade includes a main body portion and a cover portion joined to provide an enclosed manifold space. Irrigation channels extend from the manifold space to saw teeth provided on the saw blade. In one embodiment of the invention the saw teeth are provided at an end portion of the saw blade. In another embodiment of the invention the irrigation channels extend toward saw teeth provided along the longitudinal side edge of the saw blade. In either embodiment of the invention the irrigation channels commonly communicate with the fluid manifold and are uniformly distributed among the cutting teeth to provide a uniform distribution of fluid during a cutting action. Depending upon the positioning of the saw teeth on the blade and the movement provided to the blade, one embodiment of the saw blade can be used for oscillatory cutting action and another embodiment of the saw blade can be used for reciprocating cutting action.
