Abstract
Disclosed is a modular endoscope system in which a plurality of connecting pieces, tools, and cannulas which are selected according to the use thereof are assigned to a single optics. The connecting pieces and the cannulas are preferably designed for single use, so that merely the optics has to be decontaminated.
Claims26
A modular rigid endoscope comprising
- an optics cannula manufactured from a rigid material with optics comprising a bundle of image and light fibers guided through an interior thereof for image transmission,
- wherein a distal end of said optics is provided with a lens system and seal by means of a diamond glass disk,
- wherein the optics is detachably connected with the optics cannula by means of a coupling;
- a plurality of disposable, sterilized cannulas or working shafts which are designed with different diameters greater than 0.5 mm, and/or connections depending on a diagnostic or therapeutic application;
- and
- an adjustment means is provided for positioning lens-side end portions of said optics with respect to a cannula/working shaft orifice, wherein said adjustment means is, on the one hand, connected with at least one of said cannulas or working shafts and, on the other hand, with said optics, said adjustment means comprising
- a guiding pipe enclosing a protective pipe of said optics along which a sliding piece connected with the optics cannula is guided in a displaceable manner to position the optics and lens system within the optics cannula,
- said optics having an outer diameter of about 0.5 mm, and comprising light conductors and image conductors.
