In an endoscope designed for laser lithotripsy use is made of a laser lithotripsy unit having a guide tube insertable in the barrel of the endoscope, which guide tube encloses a laser light guide which carries at its distal end a fused-on head to concentrate the beam. The laser light guide is guided in the guide tube so as to be axially displaceable and immobilizable, thus making it possible for the distance between the head and the concretion intended for destruction to be adjusted to obtain optimum energy transmission, the relevant conditions being maintained during the operation by virtue of the fact that the distal end of the guide tube for the lithotripsy unit is held in contact with the concretion.

Endoscope for laser lithotripsy

A guiding probe, in particular for an endoscope for surgical endoscopy with laser light, wherein the guiding probe comprises a flexible section which is resistant to high temperatures and substantially does not absorb the laser light used, and further including an auxiliary part for introducing the probe.
