Abstract
A modular constructed surgical motor with an outer cylindrical case used as the handle, and a spaced inner motor case resiliently mounted thereto forms an air gap for reducing vibrations and heat, a separate module houses the chuck, a ball coupling made from an elastomeric material transmits rotary motion, undercuts in the spindle adjacent the vanes and in the peripheral edge enhance power, the inlet opening to the vanes are positioned to increase the volume of inlet air, the inner surface of the cylinder is contoured to define a crescent seal, the inlet and outlet to the spindle are positioned in the cylinder to increase the power stroke, the discharge holes in the cylinder are oriented for uniform contact surface, the flow passages in the cylinder cool the cylinder and bearing, and one seal cured in situ and another seal adjacent the bearing prevent leakage of oil into ambient and the surgical tool.
