Pneumatic surgical saws designed to cut bone and other hard tissue using a serrated blade that oscillates at a very high speed perpendicular to the axis of the machine without full rotation These saws are typically small, handheld, powered instruments with a pneumatic motor to drive an oscillating blade and a hose connected to the pressurized gas source. Oscillating pneumatic-power bone surgical saws are smaller and less noisy than electric saws but produce a larger amount of debris in the environment. They are used in orthopedic, cardiothoracic, and other surgical procedures.
