OSCILLATING SURGICAL SAW BLADE ASSEMBLY INCLUDING A BLADE WITH AN ASSYMETRICALLY LOADED DRIVE SHAFT

摘要

A surgical saw blade (24) including a blade mount (42), a shaft (52) that extends forward from the blade mount and a blade head (66) that extends radially outwardly from the shaft. The shaft has a mass that is asymmetric relative to the mechanical axis of oscillation (61) around which the blade mount oscillates. The shaft may have one or more sections (56, 58) that are asymmetric to the axis of oscillation that function as the asymmetric mass.
