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 method for operating a robot, including detecting the spatial position and/or location of at least one delimiting structure which causes a kinematic delimitation of the work space that can be reached by an instrument connected to a robotic arm of the telemanipulation robot; and continuously representing the reachable work space on an object to be manipulated by the instrument in such a way that a change in the position and/or location of the delimiting structure results, in real time, in a change of the represented reachable work space.
