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: 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 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: Calcium sulfate alpha hemihydrate and foundry sand are milled to cement fineness and form a hydraulic binder, as a mixture with both high early setting strength and excellent water resistance. The composition relies upon a sulfate activation of the foundry sand rather than an alkali activation thereof.
