Abstract: An instrument (14) is suitable for treatment of lung tumors and other tissues and a respective apparatus (15) detects the correct positioning of instrument (14) and its two electrodes (19, 20) in a suitable target tissue by observation of two parameters (G1, G2) and particularly their time-dependent change. If the change (V1, V2) of the two parameters (G1, G2) exceeds defined thresholds (S1, S2) respectively, a contact between the instrument and the tissue to be treated and thus also the positioning of the instrument in a desired position can be derived therefrom. This remarkably increases treatment safety.

Abstract: A system allowing automatic pairing of different apparatuses within different operation environments. The pairing is carried out based on signal strength or indoor navigation (e.g. Bluetooth). It is detected whether a communication partner, i.e. another apparatus, is present in a distance within a predefined radius (S1) from any other apparatus or from a central apparatus. During the detection the pairing is initiated automatically by (UUID) or certificate exchange without additional interaction by the user or with simple confirmation by the user.

Abstract: A surgical working instrument (3) is disclosed that is inserted in a working channel (7) of an endoscope (2) and is slidably located therein. A device (27) for determination of the relative position of the working instrument (3) to the endoscope (2) is configured to determine in an optical manner that the distal end (8) of the working instrument (3) has reached a distal end (8) of the working channel (7). The position determination device (27) comprises a light conductor (28) that is attached to the working instrument (3) and configured to receive light surrounding the working instrument (3) in the vicinity of its distal end (14), wherein based on the light received by the light conductor (28) the relative position of the light conductor (28) and thus the working instrument (3) in relation to the endoscope (2) can be determined.
