Patent number: 9784289Abstract: A medical or dental fluid-driven handle with a control or regulation circuit for the control or regulation of the rotational speed of a rotary part to a predetermined rotational speed and methods are presented. 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.Type: GrantFiled: December 9, 2014Date of Patent: October 10, 2017Assignee: W&H Dentalwerk Bürmoos GmbHInventors: Michael Rothenwaender, Karl Schmiedlechner, Norbert Schatz

Patent number: 9119690Abstract: A fluid-operated medical or dental handheld element is disclosed, having a connecting device for connecting the handheld element to a fluid source so that a first impeller can be induced to rotate by a fluid stream to cause a tool to execute a driving motion, a fluid conducting device arranged between the connecting device and the first impeller for conveying a fluid stream away from or toward the first impeller, and a generator for generating electric power. The generator includes a second rotatable impeller that can be driven by at least a substream of the fluid stream conveyable in the first fluid conducting device. One result is more constant generation and output of power by the generator independent of the rotational speed of the first impeller, thereby insuring a more constant power supply to a power consuming device connected to the generator.Type: GrantFiled: January 18, 2012Date of Patent: September 1, 2015Assignee: W&H Dentalwerk Bürmoos GmbHInventors: Stephan Rauchenzauner, Karl Schmiedlechner

Patent number: 8038439Abstract: There is disclosed a medical handpiece, in particular a dental handpiece, having a lighting device which includes at least one optical semiconductor element, whereby the at least one optical semiconductor element is arranged at least partially in the interior of the handpiece and is detachably connected to the handpiece. On account of this design, it is possible for the user to easily connect the handpiece to an optical semiconductor element that is needed for a certain treatment and has, for example, a certain desired power level and/or emits a desired wavelength. The handpiece may thus be used for different applications without requiring any additional components such as switches, etc., that take up space. The outside dimensions of the handpiece remain substantially unchanged in comparison with known handpieces.Type: GrantFiled: November 27, 2007Date of Patent: October 18, 2011Assignee: W&H Dentalwerk Burmoos GmbHInventors: Norbert Schatz, Karl Schmiedlechner
