Abstract: A method of sterilizing an object with atomic nitrogen from a nitrogen plasma includes the steps of placing the object in a sterilization chamber and a sterilization half-cycle for sterilizing the object present in the chamber. The sterilization half-cycle comprises an alternation between stages of injecting atomic nitrogen into the chamber and of intermediate stages, each intermediate stage including at least one suction stage during which the chamber is evacuated.

Abstract: A surgical handpiece includes a housing for receiving an insert, and an ultrasound piezoelectric transducer having a piezoelectric motor placed between a counterweight and an amplifier portion. The piezoelectric transducer is suitable for transmitting ultrasound waves from a distal end of the amplifier portion. The distal end is present in the housing, and rotary drive means is present in the housing. The rotary drive means are movable independently of the ultrasound piezoelectric transducer, and the transducer is static relative to the handpiece.

Abstract: An ultrasound dental treatment appliance having a surgical handpiece (220) fitted with a transducer connected to an ultrasound generator (230), the handpiece being designed to receive ultrasound tips (210) that are mechanically coupled to the transducer and that operate in different ultrasound wave power and amplitude ranges. The dental treatment appliance includes elements (224, 225), e.g. optical elements, for automatically detecting the utilization power and amplitude range of the tip (210) mounted on the handpiece, and a processor for automatically setting the ultrasound generator to the detected power and amplitude range.

Abstract: A device for producing a gas plasma by ionisation of a gas using a microwave source of determined nominal power (Pn), includes a magnetron 7 receiving its electric energy from a supply circuit. The device is characterized in that the power (Pd) delivered by the supply circuit to the magnetron 7 is no more than one quarter of the nominal power (Pn) of the magnetron 7.
