Device for a fiber-optic guide

A device for a fiber optic waveguide to attach the fiber optic waveguide to a medical laser and to an endoscope, the operating end of the endoscope having a longitudinal feed device for the fiber optic waveguide, the device comprising:

• first rigid fiber optic waveguide casing means having a preset inner diameter;
• second rigid fiber optic waveguide casing means having a preset outer diameter smaller than the preset inner diameter of the first casing means so that the second casing means can slide concentrically in the first casing means at a predetermined point;
• fiber optic waveguide means disposed within the first and second waveguide casing means;
• first detachable and adjustable clamping means for clamping the first and second casing means together at the predetermined point, said first detachable clamping means comprising collar means disposed around said second waveguide casing means and sleeve means surrounding said collar means and said first and second waveguide casing means for applying a force to said collar means thereby clamping said first and second waveguide casing means together at said predetermined point;
• and
• second detachable and adjustable clamping means for clamping the fiber optic waveguide means to the second casing means at the longitudinal feed device, whereby to adjust the amount of said fiber optic waveguide extending from said longitudinal feed device, said first and second detachable clamping means are loosened, the amount of said fiber optic waveguide extending from said longitudinal feed device desired is selected and said first and second detachable clamping means are then retightened to secure the adjustment.
