    摘要： A device used for the sterilization of objects (19), in particular medical or surgical instruments, is of the type that can create a gaseous plasma from a gas flow which is subjected to an electric field. The resulting post-discharge flow is brought into contact with the surface of the objects to be treated. The device is characterized in that the gas flow includes exclusively nitrogen. Moreover, the device include a device for heating the aforementioned objects, which can heat the objects to a temperature of at least 60° C. during treatment. A method of using the device is also described.

    摘要： A method for sterilizing objects (19), in particular medical or surgical instruments, includes subjecting a gas stream circulating in a chamber wherein an industrial vacuum is created to the action of an electric field so as to create a gaseous plasma whereof the post-discharge stream which is derived therefrom is admitted into a sterilizing chamber where it is contacted with the surface of the objects to be treated. The device is characterized in that the gas stream consists of a mixture of nitrogen, and of an amount of hydrogen less than 5%. It includes elements for heating the objects capable of bringing the latter, during treatment, to a temperature not less than 60° C.

    摘要： Method for lifting a sinus membrane located between a sinus and a maxilla that involves the drilling of a hole of a given diameter in the maxilla reaching the sinus membrane, and includes introducing in the hole an ultrasonic tip having a distal part including a ring-shaped part of increasing cross-section and a distal end formed by a flat area extending generally perpendicular to the longitudinal axis of the distal part. The flat area of the distal part has a distal side facing away from the proximal part and is bordered by a rounding, the ring shaped part being larger than the body of the tip but closely corresponding to the diameter of the hole. The tip includes an internal irrigation channel emerging on the distal side of the flat area. While the tip is within the hole, the tip is advanced towards the membrane while ultrasound vibrations are fed to the tip and irrigation fluid is supplied to the internal irrigation channel. This creates a cavitation effect in the irrigation fluid between the tip and the membrane and a lifting force that gently detaches and elevates the sinus membrane without requiring a direct contact between the membrane and the distal part of the tip.

    摘要： Method for detection and location of a difference in density and/or structure and/or chemical composition of a biological tissue (7) which is subjected to continuous illumination in a first determined band of frequencies, causing the former to generate a phenomenon of fluorescence, autofluorescence or luminescence in a second band of frequencies. The method includes the following stages: the biological tissue thus illuminated is visually captured by color video elements provided with image sensors with a mosaic of pixels provided with additional color filters; for each image point thus obtained 1) information relating to the energy received by each pixel is collected in order to reconstitute an image of the biological tissue (7), b) amplification occurs for the signal corresponding to the energy received in the second frequency band in order to characterize the biological tissue (7) difference or to cause the image thus obtained to appear.
