ABSTRACT:
A air-driven cutting device for medical treatment (a handpiece (10)) comprises a housing (18) for a head portion (14). The housing (18) accommodates a rotary cylinder (60) for holding a cylindrical cutting tool (46) inserted through the tool inlet (42) of the housing, and a turbine blade (62) mounted around and secured on the rotary cylinder. With this arrangement, a compressed air is blown onto the turbine blade to rotate the turbine blade, the rotor and the cutting tool. Particularly, a part or a whole of the end portion of the rotary cylinder in the vicinity of the tool inlet is covered with the cover section (42) of the housing. Therefore, the rotary cylinder does not contact the teeth or the tissues of the buccal cavity.
