Description

Panorama-Endoskop Die medizinische Diagnostik benutzt zur Kontrolle von Hohlräumen oder Hohlorganen, durch Einblick oder Fotografie, sogenannte Endoskope. Diese Geräte besitzen ein begrenztes Blickfeld, so daß die Gefahr des Übersehens wichtiger Merkmale gegeben ist. Das Blickfeld wird dabei in bekannter Weise mit Hilfe einer Niedervoltlampe erleuchtet.Panoramic endoscope The medical diagnostics used for control of cavities or hollow organs, through insight or photography, so-called endoscopes. These devices have a limited field of view, so there is a risk of overlook important characteristics is given. The field of view is thereby in a known manner Illuminated with the help of a low-voltage lamp.

Die Erfindung betrifft nun ein Endoskop, womit eine Panoramasicht, d. h. ein vollständiger Umblick über einen Winkel von 3600, ermöglicht wird. The invention now relates to an endoscope, with which a panoramic view, d. H. a complete view over an angle of 3600 is made possible.

Endoskope für Panoramablick mit einem konusförmigen Bildspiegel sind an sich bekannt. Der Panoramablick wird aber in Hohlorganen erst möglich, wenn mit dem Panoramaspiegel eine das Panoramablickfeld zweckmäßig ausleuchtende Belichtungseinrichtung kombiniert wird. Diese Einrichtung darf das Blickfeld nicht durch etwaige Drahtführungen od. dgl. stören. Endoscopes for panoramic views with a cone-shaped image mirror are known per se. The panoramic view is only possible in hollow organs when with the panorama mirror an exposure device expediently illuminating the panorama field of view is combined. This device must not allow the field of vision through any wire guides or the like disturb.

Gemäß der Erfindung ist daher hinter dem Panoramaspiegel ein weiterer, zur Rundumbeleuchtung geeigneter Ringspiegel angeordnet, der eine gleichmäßige Beleuchtung des Objektes dadurch gewährleistet, daß sein Beleuchtungswinkel dem Bildwinkel des Panoramaspiegels entspricht. Dabei soll die Oberfläche des Beleuchtungsspiegels eine derartige Krümmung aufweisen, daß das ihm zugeführte, vorzugsweise parallele Licht gleichmäßig über das Objekt verteilt wird. Das Licht kann hierbei beispielsweise außerhalb des Körpers erzeugt und mit Hilfe einer koaxialen Lichtleitröhre od. dgl. dem Beleuchtungsspiegel zugeführt werden. Dadurch ergibt sich, daß die Lichtintensität jede beliebige Stärke erreichen kann. According to the invention, there is therefore another, for all-round lighting arranged a suitable ring mirror, which provides uniform lighting of the object ensures that its angle of illumination corresponds to the angle of view of the Corresponds to the panorama mirror. The surface of the lighting mirror should be have such a curvature that the fed to it, preferably parallel Light is evenly distributed over the object. The light can for example generated outside the body and od with the help of a coaxial light guide tube. are fed to the lighting mirror. This means that the light intensity can reach any strength.

Da aber im Kopf eines Endoskopes eine erfindungsgemäße Spiegelkombination nur durch beispielsweise einen zweckentsprechenden Glaskörper gehaltert werden kann, so können, hervorgerufen durch die Oberflächen dieses Körpers, störende Reflexionen zu Doppel abbildungen führen. Hier kann nun, ein weiteres Merkmal der Erfindung, dadurch Abhilfe geschaffen werden, daß in den Strahlengang dieser störenden Reflexe, welche zwangläufig die optische Längsachse des Systems passieren, eine stabförmige Blende eingesetzt wird. Zweckmäßig ist die Oberfläche dieser Stabblende zu schwärzen. But there is a mirror combination according to the invention in the head of an endoscope can only be supported by, for example, an appropriate glass body, so, caused by the surfaces of this body, disturbing reflections can occur lead to double images. Here, another feature of the invention, remedial measures can be provided that in the beam path of these disruptive reflections, which inevitably pass the optical longitudinal axis of the system, a rod-shaped one Aperture is used. The surface of this rod diaphragm is expedient to blacken.

Das in der Zeichnung dargestellte Ausführungsbeispiel des Kopfes eines erfindungsgemäßen Pano- rama-Endoskopes zeigt bei 1 einen gewölbten Stirnteil zum Einführen, der die Spiegelkombination, bestehend aus dem Beleuchtungsspiegel 2 und dem an einem Hals 3 angebrachten Panoramaspiegel 4, trägt. The embodiment of the head shown in the drawing of a panorama according to the invention rama endoscope shows at 1 a curved forehead part for introducing the mirror combination, consisting of the lighting mirror 2 and the panoramic mirror 4 attached to a neck 3.

In der optischen Achse 5 der Spiegelkombination befindet sich die Stabblende 6. Der tragende Glaskörper 7 vereint den Kopf mit dem Rohrsystem 8 des Gerätes. Der Beleuchtungswinkel 9 deckt sich mit dem Bildwinkel 10.In the optical axis 5 of the mirror combination is located Rod screen 6. The supporting glass body 7 combines the head with the pipe system 8 of the Device. The illumination angle 9 coincides with the image angle 10.

PATENTANSPROCHE: 1. Endoskop mit Bildspiegel für Panoramasicht, dadurch gekennzeichnet, daß hinter dem Panoramaspiegel (4) ein zur Rundumbeleuchtung geeigneter Ringspiegel (2) angeordnet ist, der eine gleichmäßige Beleuchtung des Objektes dadurch gewährleistet, daß sein Beleuchtungswinkel (9) dem Bildwinkel (10) des Panoramaspiegels entspricht. PATENT APPROACH: 1. Endoscope with image mirror for panoramic view, thereby characterized in that behind the panoramic mirror (4) a suitable for all-round lighting Annular mirror (2) is arranged, which thereby a uniform illumination of the object ensures that its angle of illumination (9) corresponds to the angle of view (10) of the panoramic mirror is equivalent to.
