Abstract
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.
