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

Patent number: 7556498Abstract: Medical, in particular dental, contra-angle handpieces for driving a dental instrument connected to the contra-angle handpiece with shafts arranged in the contra-angle handpiece for the transmission of the drive movement to the instrument. In order to achieve a reduction of sound emission and a reduction of the manufacturing and assembly costs while still incorporating the curvature of the outer sleeve of the contra-angle handpiece and the advantages which this entails, the contra-angle handpiece is equipped with a single-piece shaft which is essentially centered at the proximal end and the distal end of the outer sleeve, but runs eccentrically in a section of the outer sleeve between the proximal end and the distal end. The curvature of the outer sleeve of the contra-angle handpiece is in the range of about 8° to about 16°, and in some implementations, in the range of about 10° to about 14°.Type: GrantFiled: June 27, 2005Date of Patent: July 7, 2009Assignee: W&H Dentalwerk Bümoos GmbHInventor: Norbert Schatz

Patent number: 6916176Abstract: A rotation locking device located in the area of two separate, independent shafts or shaft sections for preventing the undesired rotation of a shaft or shaft section. The rotation locking device includes a locking pin which, in its idle position (during operation of the appliance), rests on a displacement surface of a shaft or shaft section. In the event of the undesired rotation of a shaft (caused, for example, when a tool is being unscrewed from a coupling which is connected to the shafts), the shaft underneath the locking pin turns until the pin is forced out of the displacement surface, is displaced outwards radially and pressed against a component which is fixed to the body of the appliance (e.g. the bearing sleeve of the gearbox in which the rotation locking device is fitted). Any further rotation of the shafts is prevented in this manner.Type: GrantFiled: September 2, 2003Date of Patent: July 12, 2005Assignee: W&H Dentalwerk Burmoos GmbHInventors: Norbert Schatz, Thomas Jindra
