  • Air-driven cutting device for medical treatment
    Patent number: 7329123
    Abstract: A dental cutting device has a head portion (10) which accommodates a rotary cylinder (20) for holding a cutting tool (22), and a turbine blade (21) mounted around and secured on the rotary cylinder (20). Air fed from an air-supply port (24) is blown onto the turbine blade to rotate the same, and the air blown onto the turbine blade is exhausted from the exhaust port (25). The head portion has a first chamber (26) which is located at a portion confronting the outer peripheral end portion of the turbine blade and which extends in a direction orthogonal to the central axis of the rotary cylinder, and second chambers (27, 28) which are located adjacent to one or both ends of the turbine blade along the direction of the central axial and which communicate with the first chamber.
