Abstract
The present invention relates to an endoscope, in particular an ureterorenoscope. The endoscope comprises a lumen for insertion of a light and energy transmitting fiber. According to the invention during insertion of the fiber into a working channel of the endoscope the sharp edges of the fiber are protected by a flexible sleeve in order to avoid damages of a wall limiting the working channel. Prior to using the fiber for transmitting energy emitted by a laser the flexible sleeve is completely removed from the working channel in order to free a lumen that might be used for additional instruments or delivery of a fluid. Furthermore the stiffness of the endoscope is reduced by removing the flexible sleeve.
