摘要： An electric motor arrangement for a medical, especially dental, tool handle, which is extremely compact and resistant to sterilizing temperatures due to a plurality of advantageous embodiments. The electric motor arrangement is characterized by the following properties: the use of a light source based on SMD-LED or LED as a semiconductor chip; the shortening of the INTRAmatic coupling to between 20 mm and 25 mm; a hermetically extruded stator comprising integrated media tubes and molded connection sockets; the stator winding is embodied as a coil segment winding instead of an H winding or triangle; and the winding head has openings for media tubes.

摘要： Described herein is a dental handpiece for the endodontic treatment of a root canal, including a chuck for attaching and holding an endodontic file, an electric motor having a shaft for driving the endodontic file, and a control unit for controlling the motor, which receives a stream of input data. While monitoring the stream of input data, the control unit determines the current absorbed by the electric motor, and controls the motor so that the file alternates the direction of rotation at a frequency of from 1 to 20 Hz between a first direction and a second direction opposite to the first direction, and whereby the control unit controls the electric motor so that the file continuously rotates in the second direction when the monitored data fulfils a predetermined torque threshold condition during rotation in the first direction.

摘要： An object is to provide a control device of a dental handpiece that is able to prevent giving a shock to the operator having the dental handpiece and the patient of treatment subject and also that is able to reduce the load onto the motor and to suppress heat generation thereof. The rotational direction of a motor 20 of a dental handpiece is switched at every certain time. At this time, before the rotational direction of the motor 20 is switched through switching of a relay 17, voltage to be applied to the motor 20 is reduced. It is thereby prevented that a large current flows into the motor 20 when the relay 17 is switched, and also that a large rotation torque is applied to a cutting tool rotationally driven by the motor 20.

摘要： An electrically safe treatment system for use in treating a patient includes two or more sections coupled with a joint that permits any one section to rotate relative to another coupled section. At least one of the sections includes an electrical component. An electrical contact associated with the joint is designed to maintain an electrical connection between a pair of sections throughout an angular range of motion of one of the sections relative to the other, coupled section. The electrical contact can also maintain a total resistance of a series connection including the two sections and the contact below a specified threshold. Alternatively, one or more insulator joints may be employed to meet safety requirements.

摘要： A reciprocating endodontic hand tool in which the torque applied to an instrument such as a debriding file can be set at or below an endurance limit of the file below which failure of the instrument will not occur. In preferred embodiments the tool can switch between settings in which the torque applied to the instrument is between the endurance limit of the file and an elastic limit of the file, by setting forward and reverse angles of rotation within specified limits. This reduces or eliminates opportunities for plastic distortion, fatigue and breakage of the file during the canal debriding/cleaning/shaping process in a root canal treatment or retreatment. In some embodiments the torque may be set to at or below a durability limit of the file below which failure of the instrument will not occur through repetitive strain over the course of a particular root canal treatment or retreatment.
摘要翻译：一种往复式牙髓根治手工具，其中施加到诸如清创文件的仪器的扭矩可以设置在文件的耐力极限以下或低于该文件的耐久极限，在该耐久极限之下不会发生仪器的故障。在优选实施例中，工具可以通过在指定限制内设定正向和反向旋转角度，在施加到仪器的扭矩在文件的耐力极限和文件的弹性极限之间的设置之间进行切换。这减少或消除了在根管治疗或再治疗中的管道清创/清洁/成型过程中，锉的塑性变形，疲劳和断裂的机会。在一些实施例中，扭矩可以设定在档案的耐久极限以下，或低于该文件的耐久极限，在特定的根管治疗或再次治疗过程之前，通过重复的应变不会发生器械的失效。

摘要： The joint of the present invention facilitates connection and disconnection of the motor unit to and from the power cords in the hose, and makes the connecting area between these two parts as compact as practicable. In the joint, the motor-unit-side connector is arranged projecting from the connecting-end opening of the motor casing 10, whereas the power-cord-side connector is arranged offset from the connecting-end opening of the end cap 20, so that the two connectors are connectable inside the end cap 20.

摘要： An apparatus for controlling asymmetrical coasting of an endodontic reciprocating motor includes a controller operatively connected to the endodontic motor. The controller may include a processing unit that is configured to direct the rotation of the endodontic motor in the forward direction for a coast time and configured to direct the rotation of the endodontic motor in the reverse direction for a coast time. The forward coast time is separately calculated from the reverse coast time. A method for asymmetrically coasting a reciprocating endodontic motor includes rotating an endodontic motor in a forward direction and calculating a forward coast time for the forward direction and coasting the endodontic motor in the forward direction for the calculated forward coast time. After coasting the endodontic motor in the forward direction, the endodontic motor is rotated in a reverse direction. The reverse coast time is different than the forward coast time.

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.

摘要： A coupling device between a motor and a handpiece for dental or surgical use. An electric motor includes a nozzle for coupling to the surgical or dental handpiece, and the ratio between the length of the coupling nozzle and the external diameter of the coupling nozzle set by ISO standard 3964-1982 is between 1.8 and 2.5. The handpiece for surgical or dental use is adapted to receive the shortened coupling nozzle of the electric motor. An assembly can be formed by the handpiece and the electric motor of this type.
