    • 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.
    • 矢状锯包括刀片和构造成驱动刀片的致动器。 叶片包括第一端,与第一端相对的第二端和在第一端和第二端之间延伸的纵向轴线。 叶片第一端横向于纵向轴线延伸,并且其运动限定了叶片路径。 刀片路径包括一个闭合平面曲线,该曲线由在一个节点处相交的两个回路组成,即八字形,从而刀片路径横过自身。 致动器包括构造成循环地驱动叶片的齿轮组件,使得叶片路径在每个叶片路径循环中包括沿着纵向轴线的多个冲击推力。 此外,刀片在每个刀片循环中沿着第一方向和第二方向在第一方向上相对于第一方向切割工件。
