Application part for an endoscope
First Claim
1. In an application part for an endoscope, said application part comprising a viewing channel and a working channel extending parallel to said viewing channel;
- said working channel including a guiding means and a defined stop for slidable insertion of a fiber optic waveguide, selectively coupled to a laser light source, an improvement in said application part wherein said working channel includes an optics arrangement for concentrating the laser light emerging from the fiber optic wave guide onto a punctiform region, and further said working channel being arranged to extend beyond the optics arrangement in the direction of said punctiform region to form a shock wave reflector and further comprising a flushing channel having an outlet opening which is at least partially directed toward the face of said optics arrangement from which the light emerges.

Abstract
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.
