The invention relates to a medical turbine handpiece, in particular a dental turbine handpiece, having a drive shaft rotatably mounted in the front end region of the handpiece and to which a tool can be connected, as well as a turbine wheel arranged so as to be non-rotatable on the drive shaft and is arranged in a turbine chamber realized in the end region, into which turbine chamber a supply line for a flowing pressure medium for driving the turbine wheel opens out at an inlet opening and from which turbine chamber a removal line extends at an outlet opening, wherein at least one cross connecting channel for the pressure medium is realized in the wall of the turbine chamber, the cross connecting channel connecting the axially remote edge region of the turbine chamber to a region of the turbine chamber that is axially close to the drive shaft.

Medical air-driven handpiece with anti-retraction stop

A turbine wheel for a gas operated medical handpiece includes a plurality of blades which extend in radial direction from a hub and extend in axial direction from a side ring web of the turbine wheel, and the front side of which is substantially concavely curved about an approximately radially running first axis of curvature. In order to increase the drive power or to better exploit the drive power at least one blade has at least in an axial end region an inclination surface which is inclined in the axial direction towards the front side.
