## Abstract

The device comprises an endoscope shaft through which extends a working channel ending at an outlet side of the shaft. A guiding element extends through the working channel, said guiding element being preferably guided in longitudinal direction in and along the working channel. The device is set up in such a manner that the distal end section of an instrument extending in longitudinal direction next to the shaft can be moved alongside the shaft beyond the outlet side in order to move the working section of the instrument away from the outlet side so as to lengthen the distal end section of the device. The instrument is coupled to the guiding element in order to guide the working section of the instrument in a transverse direction away from the outlet side in a region opposite the outlet side in order to work in the region with the instrument.
