Abstract: The invention relates to a device for guiding a medical flexible shaft, in particular an endoscope shaft, to a body into which the shaft is to be inserted. The device includes a length-variable bridging device and a shaft receptacle connected to the bridging device for fixing the shaft to the bridging device. The bridging device prevents a vibration of the shaft at least at the bodily insertion orifice. The invention also relates to a medical endoscopy system comprising such a device. In addition, the invention relates to a medical endoscopy robot system including an endoscopy system of this kind. Lastly, the invention relates to a method for guiding a medical flexible shaft, in particular an endoscope shaft, to a receiving body. In accordance with the method the shaft tip is moved forwards and/or backwards to the receiving body.

Abstract: A camera system, particularly for minimally-invasive surgery, comprising an optics, wherein the optics is connected to at least one transparent film and the film is removable. Further, there is provided a method for cleaning a camera in minimally-invasive surgery wherein an optics of the camera is cleaned intracorporally by use of a cleaning device.

Abstract: The invention relates to a minimally invasive instrument comprising an enlargeable sensor head with a flat sensor element that has resilient properties. In order to enable an improved minimally invasive instrument, the sensor element comprises a film element with a first layer and with a second layer distanced from the first layer by means of spacers, wherein the sensor element comprises, arranged between the layers of the film element, expansion-sensitive, polymer-based resistance elements for picking up tactile stimuli.

Abstract: The invention relates to a liquid jet scalpel comprising a nozzle (12) for discharge of pressurized liquid (14) in the direction of tissue (16) that is to be manipulated, and a distance measuring device (18) for measuring the distance between the nozzle (12) and the tissue (16) that is to be manipulated. The invention further relates to a method for operating a liquid jet scalpel.

Abstract: A handling device, which is in particular a robot, has a receiving device for receiving different instruments. To this end, the receiving device and the different instruments have mutually compatible connecting elements. In order to ensure error-free connection of the correctly selected instrument to the receiving device, the instruments have changeable indicator devices. The indicator devices are changed with the aid of a control device, for example on the basis of a schedule.

Abstract: A method for selectively applying a liquid jet onto and/or into human or animal skin is provided. The method includes the steps of detecting and storing a position, orientation and shape of a skin patch to be processed and moving a liquid nozzle over the skin patch. The liquid nozzle is guided by a robot arm within boundaries of the skin patch and the liquid jet is applied in a pulsed manner into and/or onto the skin. At each spot of the skin patch to be processed at each point of time in processing only one liquid jet pulse each is applied and the next pulse is applied to another spot of the skin patch to be processed to prevent accumulation of liquid in the skin to thus attain penetration of the liquid jet.

Abstract: The invention relates to a minimally invasive instrument (1) comprising an enlargeable sensor head with a flat sensor element (7) that has resilient properties. In order to enable an improved minimally invasive instrument, the sensor element (7) comprises a film element (13) with a first layer (15) and with a second layer (17) distanced from the first layer (15) by means of spacers (19), wherein the sensor element (7) comprises, arranged between the layers (15, 17) of the film element (13), expansion-sensitive, polymer-based resistance elements (21) for picking up tactile stimuli.

Abstract: A cement-type binding material suitable as a building material for use in the manner of a Portland cement including for underground work, or as a curing accelerating additive in mortar cement or masonry cement or in concrete or as a basic material for producing building components, is produced by mixing flue dust or flue ash with a product obtained by desulfurizing flue gases. The quantity of flue dust or ash is so measured than any free lime and lime being freed during an oxidizing and calcining treatment is completely bound to aluminates and silicates capable of reacting with water. The so produced intermediate multi-phase product is milled to a certain fineness and mixed with slag sand also milled to a certain fineness. The so obtained product is suitable for use in all instances where gypsum could not be used heretofore or could be used only under expensive protective measures.
