Abstract: An endoscope has a tubular shaft whose interior contains components, in particular lenses, spacers, diaphragms, prisms and filters of an optical system, said components being at least partially surrounded by a support piece made of shrunk material. It is proposed that the components be surrounded by a transparent and tube-sleeve-shaped shrunk material which has been shrunk before the components are introduced into the tubular shaft.

Abstract: An endotracheal device for use with a supra-laryngeal mask including a video display for providing images of the area ahead of the endotracheal device to facilitate insertion without damaging the surrounding tissue; the endotracheal device having a flexible portion and a rigid portion maintaining a light and an image guide for transmitting illuminating light ahead of the endotracheal device and for transmitting reflected light from the area ahead of the endotracheal device.

Abstract: A rod lens with one or more optically active surfaces and one or more inactive surfaces, in which one part of the optically inactive surface or surfaces, especially a lens facet and/or radial peripheral surface of a lens, is smooth, and a method for smoothing one part of one or more optically inactive surfaces of a lens, especially of a lens facet and/or radial peripheral surface of a lens. As a result, the occurrence of fissures in the lens is prevented or reduced.

Abstract: Distance holder for lenses, which in terms of shape or material structure is configured in such a way that it exerts a slight notching effect on lenses on contact surfaces between a distance holder and a lens, so that the lens surface is less easily damaged.

Abstract: A laryngoscope with a detachable camera, the system providing illuminating light to and images of the area ahead of the laryngoscope to facilitate insertion of the laryngoscope without damage to the surrounding tissue, the system including a keyed attaching device for facilitating attachment of camera and laryngoscope in a correct orientation.

Abstract: An apparatus for testing the state of the optical system of an endoscope comprises a first supporting device for the endoscope, a test pattern and a second supporting device for the test pattern, wherein the test pattern comprises a pattern, which allows a check of the actual viewing direction and of the actual field of view angle within tolerance values.

Abstract: A laryngoscope includes a handle, a spatula arranged substantially transverse to the handle, and a coupling detachably fixing the spatula to the handle. An illumination light waveguide guides an illumination light signal and an image waveguide guides an image signal, both waveguides being attached to the spatula. The illumination light waveguide includes a proximal end having an illumination light entry opening, and the image waveguide includes a proximal end having an image exit opening, wherein the illumination light entry opening and the image exit opening are arranged in the area of the coupling. The handle includes, in the area of the coupling, an illumination light exit opening and an image entry opening which allow for the illumination light signal to couple into the illumination light waveguide from the handle, and for the image signal to couple out of the image waveguide. A centering element automatically aligns the image entry opening and the image exit opening precisely to each other.

Abstract: A device for positioning components within endoscopic systems includes a hermetically sealed housing. An outer ring element is mounted to rotate about the outer side of the housing and carries on its circumference at least one outer magnet. Further, an inner ring element is mounted inside the housing and carries likewise at least one inner magnet, the magnets being aligned in such a way that any rotation of the outer ring element has the effect to move the at least one inner magnet by magnetic coupling, such movement serving the purpose to position the respective components. In order to achieve a simple, relatively small and functionally safe structure it is proposed that both the outer and inner ring elements be configured as axially displaceable rings carrying the oppositely arranged magnets, and that the inner ring be mechanically connected with the component to be positioned.
