A dental or surgical handpiece which operates on the basis of laser includes a light guide for the laser which, in order to ensure the relative rotation between supply hose and handpiece, is arranged concentrically in the coupling between the supply hose and the handpiece. The light guide of the supply hose extends in one piece into the handpiece and, starting from the coupling with the supply hose, the light guide is displaced increasingly eccentrically toward the inner side of the bend of the angle piece, and the end of the light guide is rotatably mounted in a receiving unit of the handpiece.

Laser-operated dental handpiece

An adjusting device for a pneumatic drive, particularly a pneumatic drive of a medical or dental instrument, for example, a handpiece or angle piece, which delivers its energy by vibration and in which the vibrations are produced by a pneumatic drive, wherein an air flow is controlled by having an air supply line and an air discharge line end at a distance from each other at a surface and by providing a counter-surface which is movable relative to the surface and, which, in dependence of its position relative to the surface, forms a flow path with a defined flow resistance between the air supply line and the air discharge line.

Adjusting device for a pneumatic drive, particularly for a medical or dental instrument

A dental handpiece includes a turbine arranged in a handpiece head for rotating a tool, wherein the turbine is supported by slide bearings or roller bearings arranged on the side of the rotor or turbine facing the tool and on the side of the rotor or turbine facing away from the tool. The handpiece head includes an air duct for the propulsion air and a return duct for the returned or used air. At least one opening in the turbine chamber wall in the area near the axis is connected through a connecting duct to the return duct.

Dental handpiece

A chucking device for holding a dental tool by a collet chuck with collet chuck sleeve, wherein the collet chuck can be released by a push button against the force of clamping spring. The collet chuck sleeve has at both ends thereof axial slots, so that it is constructed at both ends as a collet chuck. The casing of the collet chuck is undercut at both ends, wherein the undercut at the side of the tool is mounted in an axially fixed, but rotating conical seat and the undercut on the side of the push button is mounted in a conical seat of an actuating member. The actuating member is under the influence of the clamping spring and, for releasing the collet chuck, the actuating member is displaceable against the force of the clamping spring toward the axially fixed seat. Instead of the collet chuck, it is also possible to provide two axially spaced apart groups of radially displaceable clamping elements.
