Abstract
A dental handpiece which includes a driving motor located within an essentially cylindrical housing; energy means infeed conduits for the motor and a supply hose containing at least one cooling medium infeed conduit being connectable to one end of the housing through the intermediary of a connector part, and also containing an energy supply conduit for the motor; and to whose other end there is attachable a gripping member onto a drive shaft extending out of the housing, so as to be readily exchangeable, the gripping member being rotatable with respect to the housing, containing a head portion with a work tool at the free end thereof, and at least one conduit for conveying the cooling medium from the connecting portion for the supply hose to the head portion of the gripping member. The cooling medium conduit is divided along the motor housing and the gripping member into two fixedly displaced conduit portions which are interconnectable between the housing and the gripping member by means of coupling means located concentrically with the drive shaft, a power-transmission shaft engaging with the latter.
