Patent ID: 8287448

Claim:
Endoscope comprising a flexible catheter probe having a plurality of lumens, a hand grip provided at the proximal end of the probe, an optical system provided in at least one optical lumen of the catheter probe, at least one working lumen for a surgical instrument, and a single elongated control element attached at or near the distal end of the probe for bending the end of the probe and displacably guided in axial direction on the probe, wherein a torsion-resistant probe attachment member is provided at the proximal end of the catheter probe, said member having a plurality of lumen outlets for the probe lumens and a torsion-resistant guide device inside which said single elongated control element is guided at the proximal end of the catheter probe is to be connected non-rotatingly to the hand grip by a releasable lock for a torque proof connection between the catheter probe and the hand grip and the single elongated control element is to be connected by means of a releasable fastener to a slider guided inside the hand grip, that the distal end of the optical lumen has a transparent seal, and that the optical system is displaceably disposed inside the optical lumen and can be removed from the optical lumen, wherein the slider is displacably mounted on a housing of the hand grin by a device for converting a rotational movement into a linear axial movement, including a crank assembly.
