A medical or dental device for determining a bone's quality by cutting a thread into the bone with a rotating threaded element comprises a control unit having a measurement circuit configured: (i) to determine values of the motor current via a first electrical contact device with which the motor drive is supplied for rotational drive of the threaded element that can be connected to the motor drive, the current values being a measure of the bone's quality; (ii) to monitor and/or to determine the penetration depth of the threaded element into the bone, and (iii) to generate measurement signals which show the relationship between the penetration depth and the determined current values or parameters derived therefrom, and to transmit these signals to a display unit, which displays the relationship between the determined current values or parameters derived therefrom, in particular the bone's quality, and the penetration depth.

A medical, particularly a dental or dental surgical, ultrasonic treatment device for generating ultrasonic vibrations and transmitting the ultrasonic vibration to a tool, which can be connected to the ultrasonic treatment device, the medical ultrasonic treatment device having: an ultrasonic vibration generator with a plurality of piezoelectric elements to which an electric voltage can be applied, and a circuit board to supply the plurality of piezoelectric elements with the electric voltage. Furthermore, a method for manufacturing a corresponding medical ultrasonic treatment device is described.

Medical ultrasonic treatment device

A vibration-transmitting medical tool-coupling device includes a first coupling element and a second coupling element, wherein one of the two coupling elements is designed as a coupling protrusion insertible into a coupling recess on the other coupling element, wherein the coupling protrusion and the coupling recess each have a first section having a thread with at least one thread flight for releasable connection of the two coupling elements and one second section which is designed so that the two coupling elements can be positioned relative to one another and are displaceable along the shared longitudinal axis before the two coupling elements can be connected releasably to one another by the thread. A guide ring which extends around the coupling protrusion is provided on one end of the thread which is arranged on the coupling protrusion and the at least one thread flight of the thread ends at this guide ring.

Drive axle for dental or medical device

A fluid-operated medical or dental handle with a device for limiting the rotational speed to a maximum rotational speed value is disclosed. The handle comprises a rotating part that can be induced to rotation by a driving fluid for driving a tool connectable to the rotating part, an electrodynamic transducer driven by the rotating part for induction of an electric voltage, wherein the electrodynamic transducer has at least one coil and a magnetic element and at least one switch element for optional opening and closing of a circuit between the two ends of the at least one coil, so that with the circuit closed, an electric current and an induced magnetic field that decelerates the rotational speed of the rotating part and the tool connectable thereto can be induced in the coil of the electrodynamic transducer.

Laser treatment appliance having an illumination system, in particular for use in the field of medicine, has a laser light source for producing a treatment laser beam which is guided essentially freely, as well as an illuminating light source for producing a visible light for illuminating an area to be treated, and one or more first optical elements via which the treatment laser beam is passed on, with at least one of the first optical elements being in the form of an optical multifunction element, such that the visible light for illumination is also steered at least over this at least one optical multifunction element. The laser treatment appliance furthermore has an optical evaluation apparatus for diagnosis or analysis of radiation which is produced during the treatment process, and all the optical multifunction elements are designed such that they influence the treatment laser beam and the visible illuminating light essentially in an equivalent reflecting and/or transmitting manner. The laser treatment appliance furthermore has a beam splitter, which extends at least over the entire cross section of the treatment laser beam, for outputting the radiation, and which is arranged between the laser light source and the first multifunction element in the incidence direction of the treatment laser beam such that the visible light from the illuminating light source does not pass through it.
