A process and also to a system for cleaning and maintaining a medical hand-held instrument, in particular a dental hand-held instrument, with an elongate grip sleeve in which elements are arranged which pertain to a drive arrangement and which are, in particular, rotatably supported, for example a shaft. For the purpose of cleaning and maintaining the hand-held instrument different media are conducted through it. In this connection a first medium, for example oil, is conducted merely through a power-transmission region surrounding the elements of the drive arrangement, whereas, on the other hand, a second medium, for example a cleaning agent, is conducted additionally also through at least one further cavity within the hand-held instrument.

Process and system for cleaning and maintaining and for operating a medical hand-held instrument

The invention relates to a medical or dental-medical treatment instrument ( ) having a media line, in particular for water or spray, extending from its rearward end to its forward end region, in which line an exchangeable filter element ( ) is arranged. In order to reduce the flow resistance of the filter element ( ), while providing a small cross-sectional size, the filter element ( ) has the form of a sleeve and the direction of passage of the medium is directed transversely to the sleeve wall ( ).

Medical or dental-medical treatment instrument having a filter element

The invention relates to a medical, in particular dental-medical handpiece ( ) having a rod-shaped grip part in the forward end region of which there is arranged a holding device ( ) having a lateral insertion opening ( ) for a working tool ( ), whereby the middle axis ( ) of the insertion opening ( ) includes, with the middle axis ( ) of the grip part extending rearwardly from the point of intersection with the middle axis ( ), an obtuse angle (W ). In order to improve the suitability of the handpiece ( ) also for use in small spaces of the body to be treated, a forward grip section ( ) of the grip part is curved towards the side ( ) of the handpiece ( ) away from the insertion opening ( ), and the obtuse angle (W ) is smaller than 103&deg; and greater than 95&deg;.
