Probe for endoscope controlled concrement disintegration - has at distal end radiation point(s), radiating in electrohydraulic impact wave direction of propagation

摘要

The light radiation points (14) are pref. formed by the radiation ends of optical fibres or thin bundles via which light is transmitted at the proximal end of the probe. The light radiation points can be arranged in the shape of a target cross, or as one or more target circles. Coloured laser light is used as the radiation source. One or more sensor points or optical fibres are arranged in the distal probe region, for measuring or transmission of the reflected light. USE/ADVANTAGE - For lithotryptor probes with precise targetting avoiding risk of damaging corresponding tissue.
