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.
