First flexible dual-channel laser uretero-renoscope

The Cobra - Lithotripsy by Laser

Up to now, laser lithotripsy with a flexible uretero-renoscope was often a complicated and time-consuming form of therapy. At Richard Wolf, we looked into the problems involved and then took on the challenge. The result was well worth the effort. What emerged was an instrument that solves all the problems encountered by the user when fighting with flexible laser lithotripsy.

"The COBRA" with 2 large irrigation and instrument channels

During laser lithotripsy with a standard flexible uretero-renoscope, the laser fibre must be continuously exchanged for a tipless basket to retrieve the stone fragments from the kidney.
The fibre must be reinserted repeatedly to disintegrate further concretions. This procedure needs to be repeated time and again not only costing time but also causing frustration and wear and tear on the instrument.

Here, our new flexible uretero-renoscope "the COBRA" with 2 large irrigation and instrument channels is a considerable help. One channel is primarily for a laser fibre but can also be
used exclusively as an irrigation channel. A further channel provides not only the option of continuous irrigation but also allows use of a stone basket, forceps and similar instruments up to 3 Fr. This channel can, of course, also be used for irrigation. This achieves a high-flow irrigation.

Advantages of the Cobra

  • Separate working channel for 230 μm laser fibres
  • Simple control of the laser fibre with special laser shifter
  • Best picture quality due to option of irrigation through 2 channels at the same time or continuous irrigation
  • Less damage to the working channel caused by laser fibres
  • Faster working without constantly changing between laser fibre and stone basket

Fast stone extraction and better overview

Following successful lithotripsy, a tipless basket can then be extended from the second channel to retrieve the stone fragments. Stones held in the basket can also be fragmented easily with the laser.

The two irrigation and working channels can be used either for continuous irrigation or both together with auxiliary instruments inserted for simple irrigation.

"The COBRA" can, of course, be used with all commercially available camera systems.
