Abstract
Description
Die Erfindung betrifft ein Endoskop.The The invention relates to an endoscope.
Jedes Endoskop benötigt einen Bildleiter, der das Bild vom distalen Ende zum proximalen Ende transportiert. Bei Videoendoskopen sitzt distal eine Videokamera und der Bildleiter, der über die Länge des Schaftes verläuft, besteht nur aus einem elektrischen Kabel. Gattungsgemäße Endoskope weisen dagegen optische Bildleiter auf, die als Relaislinsenanordnung oder als geordnetes Lichtleitfaserbündel ausgebildet sind, um das Bild über die Länge des Schaftes zu transportieren. Dabei benötigt der Bildleiter einen erheblichen Querschnitt über die gesamte Länge des Schaftes.each Endoscope needed an image guide, the image from the distal end to the proximal Transported at the end. For video endoscopes, a video camera is located distally and the picture director who over the length of the Shank runs, consists only of an electrical cable. Generic endoscopes have, on the other hand, optical image guides which act as a relay lens arrangement or are formed as an ordered optical fiber bundle to the Picture over the length to transport the shaft. In this case, the image guide requires a considerable Cross section over the entire length of the shaft.
Gattungsgemäße Endoskope weisen eine eingebaute Einrichtung zur Abstrahlung von Beleuchtungslicht auf. Früher waren dies am distalen Ende des Endoskopes angeordnete Glühlampen. Neuerdings tendiert die Entwicklung ebenfalls wieder zu distal angeordneten Lichtquellen, nun jedoch in Form von LED's.Generic endoscopes have a built-in device for emitting illumination light on. Earlier these were bulbs arranged at the distal end of the endoscope. recently The development also tends to be distally arranged again Light sources, but now in the form of LEDs.
Überwiegend werden jedoch seit langem Lichtleiter mit Lichtleitfasern verwendet, die den langgestreckten Schaft des Endoskopes durchlaufen, am distalen Ende in der gewünschten Richtung abstrahlen und am proximalen Ende an eine Lichtquelle angeschlossen sind. Alle Beleuchtungseinrichtungen benötigen jedoch zusätzlich erheblichen Querschnitt im Schaft.Mostly however, optical fibers have long been used with optical fibers, which pass through the elongated shaft of the endoscope, at the distal end End in the desired Radiate direction and connected at the proximal end to a light source are. However, all lighting devices require additional considerable Cross section in the shaft.
Man hat immer wieder die Frage diskutiert, ob es möglich ist, das Beleuchtungslicht über den optischen Bildleiter zu transportieren. Alle diese Überlegungen sind aber daran gescheitert, dass der optische Bildleiter dann in distaler Richtung Licht mit hoher Intensität transportieren muss, während er in proximaler Richtung das sehr schwache Licht des betrachteten Bildes transportiert. Rückreflexionen des Beleuchtungslichtes im Bildleiter an Linsenflächen, optischen Störungen und dergleichen, können nicht restlos vermieden werden. Aufgrund des hohen Intensitätsunterschiedes wird daher das Bild stets vom Beleuchtungslicht überstrahlt oder stark gestört.you has repeatedly discussed the question of whether it is possible to illuminate the light over the transport optical image guide. All these considerations but have failed because the optical image guide then in distal direction must transport light with high intensity while he in the proximal direction the very weak light of the considered Transported image. backreflections of the illumination light in the image guide to lens surfaces, optical disorders and the like can can not be completely avoided. Due to the high intensity difference Therefore, the image is always outshined or greatly disturbed by the illumination light.

Die Aufgabe der vorliegenden Erfindung besteht darin, die durch die Beleuchtung bedingten Platzprobleme zu verringern.The Object of the present invention is that by the Lighting conditional space problems decrease.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.These The object is achieved with the features of claim 1.
Die Erfindung geht von der Grundidee aus, das Bildlicht und das Beleuchtungslicht anhand der verwendeten Wellenlängen vollständig zu trennen. Es wird also Licht außerhalb des sichtbaren Bereiches durch den Bildleiter in distaler Richtung transportiert und nach Auskoppeln aus dem Bildleiter durch Fluoreszenz in sichtbares Licht umgewandelt. Als anregendes Licht muss dafür ultraviolettes Licht verwendet werden. Reflexionen des ultravioletten Lichtes im Bildleiter stören nicht, da es vom Auge nicht wahrnehmbar ist. Da ein Lichtleiter nicht benö tigt wird, kann der Schaft schlanker ausgebildet werden. Es wird Raum und Material gespart.The Invention is based on the basic idea, the image light and the illumination light based on the wavelengths used Completely to separate. So it becomes light outside the visible range transported by the image guide in the distal direction and after Decoupling from the image guide by fluorescence into visible light transformed. As stimulating light must be used for ultraviolet light become. Reflections of ultraviolet light in the picture guide do not disturb because it is imperceptible to the eye. Since a light guide is not needed, the shaft can be made slimmer. It becomes space and material saved up.
Es muss natürlich dafür gesorgt werden, dass das im distalen Endbereich des Endoskopes von dem UV-bestrahlten fluoreszierenden Farbstoff erzeugte, sichtbare Licht nicht rückwärts wieder in den Bildleiter zum Auge des Betrachters hin gelangt. Nach Anspruch 2 ist dazu vorteilhaft ein den Rückweg sperrendes Filter vorgesehen, das sichtbares Licht nicht zurücklässt, wohl aber ultraviolettes Licht in distaler Richtung durchlässt.It must of course ensured be that in the distal end of the endoscope of the UV-irradiated fluorescent dye produced, visible light does not reverse back gets into the picture ladder to the eye of the beholder. According to claim 2 is advantageous to the way back locking filter, which does not leave visible light, well but allows ultraviolet light to pass in the distal direction.
Der das UV-Licht umwandelnde Farbstoff kann fluoreszierend oder auch phosphoreszierend ausgebildet sein und kann Licht in gewünschter Farbe erzeugen. Vorteilhaft erzeugt er gemäß Anspruch 3 weißes Licht durch Fluoreszenz.Of the The UV-converting dye can be fluorescent or too Be formed phosphorescent and can light in the desired Create color. Advantageously, it produces white light according to claim 3 by fluorescence.
