摘要： A chuck assembly for a dental handpiece includes a hollow cylindrical tube portion having a first internal bore, and a chuck portion having a second bore. The chuck portion is supported within the first bore co-rotational with the tube portion about a common axis. The chuck portion has an annular body portion defining the second bore for supporting a cylindrical tool therein. A drive element comprising a drive pin inserted in a first end of the tube portion traverses the first internal bore at a first end of the tube portion. The drive pin cooperates with a distal end of a rotary tool insertable into the second bore to transfer torque to the tool. The tool has an elongated body portion having a driven portion and a working portion. The driven portion includes a shank portion with channels for receiving the drive pin.

摘要： A detection system for remotely determining the speed of a rotating tool tip in a pneumatic dental handpiece. A means for detecting the speed of the rotating tool tip monitors a periodic mechanical function at the pneumatic hose connected to the handpiece. The monitored periodic mechanical function serves to provide feedback that is used to control the speed of the rotating tool tip. The means for detecting the speed of the rotating tool detects a mechanical function of the rotating tool tip, which in transmitted to a controller. The controller in turn regulates the operation of an air supply valve in response to the detected mechanical function. The valve regulates the flow of air to the handpiece. By continuously adjusting the flow of air through the valve into the pneumatic hose, the speed of the rotating tool is maintained at the desired cutting speed.
