Surgical saw blade cartridge and coupler therefor

Abstract

The saw blade cartridge includes a saw blade and a cassette. The cassette is disposed above a proximal portion of the saw blade and includes first and second cassette portions opposed across the proximal portion. Each portion includes a shell and a damper. The shell has a first stiffness and an outer surface. The damper has a second stiffness less than the first stiffness and is disposed on the inner surface of the shell. The cassette portions are substantially fixed relative to the proximal portion and substantially aligned with each other. The shells are fixed relative to each other. The damper contacts the proximal portion. A handpiece coupler for engaging either the saw blade cartridge or the saw blade includes a release button with a lock button slidably disposed therein to resist unintentional opening.
