Abstract:
1. A bone saw blade assembly for use with a bone saw, the bone saw blade assembly comprising: an elongated hone saw blade having (i) a cutting end having a number of elongated cutting teeth configured for oscillatory cutting and (ii) a mounting end opposite the cutting end and configured to be coupled with a chuck of the bone saw, wherein each elongated cutting tooth is spaced apart from an adjacent elongated cutting tooth to define an elongated slot therebetween; and an elongated bone saw blade guard coupled to the bone saw blade and movable with respect to the bone saw blade in a longitudinal direction toward the cutting end of the bone saw blade from a retracted position to an extended position, the bone saw blade guard reducing the cutting effectiveness of the bone saw blade when located in the extended position and comprising a lateral band coupled to each of the elongated cutting teeth and each of the plurality of slats, wherein the elongated bone saw blade guard comprises (i) a plurality of slats and (ii) a lateral band coupled to each of the elongated cutting teeth and each of the plurality of slats, each slat positioned in a corresponding elongated slot of the elongated bone saw blade and movable in the longitudinal direction with respect to the plurality of elongated teeth between the retracted position in which the elongated teeth extend beyond each of the plurality of slats and the extended position in which each of the plurality of slats extend beyond each of the plurality of elongated teeth.
