The disclosure relates to an application part for rigid or flexible endoscopes having a viewing channel and a working channel extending parallel to the viewing channel, with the working channel being equipped with a guide as well as a defined stop for a fiber optic waveguide, which can be inserted and coupled with a laser light source, and the working channel having optics for concentrating the laser light emerging from the fiber optic waveguide onto a punctiform area. The part of the working channel surrounding the punctiform area is formed as shock wave reflector. Further, a flushing channel is provided, the outlet opening of which is at least partially directed onto the face of the optics from which the light emerges.
