The handle comprises a rotary part that can be set in rotary motion by a drive fluid, a fluid line carrying the drive fluid to or from the rotary part or a fluid branch line that is connected to a fluid line carrying the drive fluid, and a control or regulation circuit that is designed to control or regulate the rotational speed of the rotary part. An electrodynamic converter is driven by the rotary part for generating electrical energy. An actuator element is configured to act on the drive fluid and is electrically connected to the electrodynamic converter such that the actuator element is supplied with electrical energy generated by the electrodynamic converter.

摘要： The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); a driving state detecting unit (resistor for load detection, root canal length measuring circuit); and a controller. The hand piece drivably holds a cutting tool on a head unit. The power source drives the cutting tool. The driving unit drives the cutting tool with twist driving in which the normal rotation and the reverse rotation are repeated. The driving state detecting unit detects a driving state of the cutting tool. The controller changes at least one parameter of a rotation angle in the normal rotation, a rotation angle speed in the normal rotation, a rotation angle in the reverse rotation, and a rotation angle speed in the reverse rotation in accordance with the driving state of the cutting tool detected by the driving state detecting unit.

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.

摘要： A dental tool displacement apparatus for use with a motorized power handle to displace a dental tool includes a tool holder having a receptacle for receiving the dental tool, and a drive arrangement. The drive arrangement defines a transmission from the motorized power handle to the tool holder such that the tool holder undergoes reciprocating motion parallel to the tool axis at a first frequency of oscillations per minute and rotates about the tool axis at a second frequency of rotations per minute. In some cases, the two types of motion are generated by an eccentric drive pin engaging an annular slot which has gear teeth along one side, thereby generating an angular rotation step of the tool holder during each reciprocating stroke. In some cases, the first frequency is at least one order of magnitude greater than the second frequency.

摘要： A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.
