ABSTRACT:
A miniature motorized hand held dental saw wherein, like with a coping saw, the axis of rotation of the handle of the dental saw is tangent with the outer diameter of the blade. This important characteristic, combined with the use of a flexible blade, enables the operator to change, as needed, the direction of the cut without any snagging or binding effects. The dental saw is composed of a main steel body on which are attached three flanged Teflon.TM. coated bearings that support and guide a 0.004 thick annular diamond coated blade. The rotation of the blade, on these flanged bearings, is created by a drive assembly consisting of two opposite wheels, a drive wheel and a follower wheel, each wheel composed of a hub on which is fitted a neoprene o-ring. The opposite o-rings create an equal pressure on both faces of the blade which they make rotate. The power is transmitted to the assembly by means of a drive cable that is connected to a motor situated in a remote stationary work station.
