The purpose of this paper is concerned with a development of an air-powered handpiece for surgical operation. The handpiece is the tool of surgical instruments and it can be used to interchange multiple attachments for drilling, pinning, sawing, driving screws and reaming. Most of domestic medical instruments bring in overseas and the air-powered handpiece imported from foreign countries at 100％ too. Therefore we develop new air powered handpiece. we research in 2D and 3D modeling, design of air line, analyze structure. The air-powered handpiece composes of body, power supply air-line, elements for mechanical power transmission, attachment, and surgical tools. The handpiece is developed by several processes that 3D design, machining, heat treatment and coating. The developed handpiece is experimented to confirm check the efficiency.

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.
