The purpose of this paper is concerned with a battery type powered handpiece drive system for surgical operation. Battery type powered surgical handpiece is suitable for delicate surgical operating. The conventional air-type handpiece has a mechanical noise, a strong oscillation and a danger of infection. And the conventional contact switching type handpiece has problems that is restricted by surroundings. By reason of this kind, we studied noncontact switching type surgical handpiece to change conventional air type surgical handpiece and contact switching type. Also in this paper we develop the battery type power handpiece drive system for surgical operation using controller IC UC3625 of UNITRODE CO. Finally some experimental and simulation results are provided to demonstrate the validity of the proposed battery type power handpiece drive system.
