Abstract

A sagittal saw includes a blade and an actuator configured to drive the blade. The blade includes a first end, a second end opposed to the first end, and a longitudinal axis extending between the first end and second end. The blade first end extends transverse to the longitudinal axis, and its movement defines a blade path. The blade path comprises a closed plane curve consisting of two loops meeting at a node ie, a figure-eight, whereby the blade path crosses over itself. The actuator includes a gear assembly configured to cyclically drive the blade so that the blade path includes multiple impulsive thrusts along the longitudinal axis in each blade path cycle. In addition, the blade cuts the work piece in both a first direction and a second direction in each blade cycle, the second direction opposed to the first direction.
