Claim 0:
1. An endoscope with an endoscope body, endoscope head extending in an axial direction, and a work channel arrangement for guiding medical tools and/or for the flow of media up to a distal endoscope head, the work channel arrangement comprising:
a work channel configured to be flexurally elastic at least in sections and extendable relative to the endoscope body, the work channel being movable between a first position, in which a work channel exit at a distal end of the work channel is oriented in the axial direction of the endoscope head, and a second position extended distally relative to the first position;
a guiding device configured to deflect the work channel exit in a predetermined lateral or retrospective direction relative to a longitudinal axis of the endoscope, when the work channel is in the second position; and
a deflection device comprising an entrainer which is anchored at the work channel in an area of the work channel exit and operable from a handle part of the endoscope, the entrainer being configured to pull the work channel from the first position to the second position, the entrainer being positioned distally in front of the distal end of the work channel when the work channel is in the first position, and, being configured to, upon applying a tensile force to the entrainer from the proximal direction, first pull the work channel distally relative to the endoscope body and then pull the work channel into the predetermined lateral or retrospective direction relative to the longitudinal axis of the endoscope, when the work channel is in the second position.
