Abstract

The equipment indicates the position of an endoscope inside a boiler chamber etc. The distal end has a basic lens and light-emitting lenses and a protective cap. Between the cap (3) and the distal end (1) is a transparent annular tube (10) round the periphery of the basic lens (6). This is filled with liq. so as to enclose an air bubble. The liquid can contain a contrasting agent. USE/ADVANTAGE - Clear indication of position, the bubble remaining at the 12 o'clock position in the tube and being visible through the endoscope eyepiece.

Description

Die Erfindung betrifft eine Anordnung zur Lageanzeige eines Endoskopes in einem technischen Hohlraum.The invention relates to an arrangement for indicating the position an endoscope in a technical cavity.

Bei der Anwendung eines Endoskopes in einem technischen Hohlraum ist aufgrund der Flexibilität des Endoskopar­ beitskanals keine eindeutige Kenntnis über die Lage des Distalendes des Endoskopes im Hohlraum, z. B. in einem Dampfkesselsammler, möglich. Dies hat zur Folge, daß damit auch keine eindeutige Zuordnung der über die Bild­ eintrittsöffnung übermittelten Bilder innerhalb des tech­ nischen Hohlraumes gewährleistet ist.When using an endoscope in a technical Cavity is due to the flexibility of the endoscopic beitskanals no clear knowledge of the location of the Distal end of the endoscope in the cavity, e.g. B. in one Steam boiler collector, possible. This has the consequence that so that no clear assignment of the over the picture Entrance images transmitted within the tech African cavity is guaranteed.

Ein mit einer Biegesteuereinrichtung versehenes Endoskop (DE-OS 39 36 096) ergibt ebenfalls keine eindeutige Kennt­ nis über die Lage des Distalendes im Hohlraum. Es ist kein Feststellen von "oben" und "unten" im technischen Hohl­ raum möglich, wenn nicht konstruktive Merkmale darauf hin­ weisen.An endoscope provided with a bending control device (DE-OS 39 36 096) also gives no clear knowledge nis about the location of the distal end in the cavity. It is not Finding "above" and "below" in the technical cavity space possible if not constructive features indicate point.

Ziel der Erfindung ist, eine eindeutige Lageanzeige für das Distalende des Endoskopes zu erreichen.The aim of the invention is a clear position indicator for to reach the distal end of the endoscope.

Der Erfindung liegt die Aufgabe zugrunde, das Distalende mit einer über den Bildkanal zu übertragenden Lageanzeige zu versehen.The invention has for its object the distal end with a position indicator to be transmitted via the image channel to provide.

Dies wird dadurch erreicht, daß erfindungsgemäß zwischen der Schutzkappe und dem Distalende über den Umfang des Grundobjektivs ein mit einer Flüssigkeit unter Einschluß einer Luftblase gefülltes transparentes Ringrohr ange­ ordnet ist.This is achieved in that according to the invention between the protective cap and the distal end over the circumference of the Basic lens one with a liquid under confinement an air bubble filled transparent ring tube is arranged.

An einem Ausführungsbeispiel wird die Erfindung näher er­ läutert. Die Zeichnung zeigt: In one embodiment, the invention he he purifies. The drawing shows:  

Fig. 1 das Distalende des Endoskopes mit geschnittener Schutzkappe in seitlicher Ansicht; Figure 1 shows the distal end of the endoscope with a cut protective cap in a side view.

Fig. 2 das Distalende des Endoskopes in Vorderansicht ohne Schutzkappe. Fig. 2 shows the distal end of the endoscope in front view without a protective cap.

Das Distalende 1 des Endoskopes besitzt den Schraubring 2, mit dem die Schutzkappe 3 oder das Wechselobjektiv 4 am Distalende zu befestigen ist. Die Schutzkappe 3 dient zum mechanischen Schutz der zwei Lichtaustrittsoptiken 4; 5 sowie des Grundobjektivs 6 und ist mit den Bohrungen 7; 8 für den Lichtaustritt und die Bohrung 9 für das Grund­ objektiv 6 des Bildleiters vorgesehen. Vor dem Grund­ objektiv 6 des Endoskopes ist ein transparentes Ringrohr 10 angeordnet, welches mit einer Kontrast-Flüssigkeit 11 unter Einschluß einer Luftblase 12 gefüllt ist (Fig. 2). Das transparente Ringrohr 10 ist so bemessen und ange­ ordnet, daß die Luftblase 12 durch die Endoskopoptik zu sehen ist. An der Frontseite des Distalendes 1 sind Ab­ standhalter 13 zur Gewährleistung des Abstandes zwischen Schutzkappe 3 oder Wechselobjektiv 4 zum Grundobjektiv 6 angeordnet.The distal end 1 of the endoscope has the screw ring 2 with which the protective cap 3 or the interchangeable lens 4 is to be attached to the distal end. The protective cap 3 serves to mechanically protect the two light exit optics 4 ; 5 and the basic lens 6 and is with the holes 7 ; 8 provided for the light emission and the hole 9 for the base lens 6 of the image guide. In front of the base lens 6 of the endoscope a transparent ring tube 10 is arranged, which is filled with a contrast liquid 11 including an air bubble 12 ( Fig. 2). The transparent ring tube 10 is dimensioned and arranged so that the air bubble 12 can be seen through the endoscope optics. At the front of the distal end 1 are from stand 13 to ensure the distance between the protective cap 3 or interchangeable lens 4 to the base lens 6 .

Die Wirkungsweise ist folgende: Das Endoskop wird in einen konstruktiv kompliziert aufge­ bauten technischen Hohlraum, z. B. ein Regelventilgehäuse, eingeführt, ohne daß die genaue Lage des Distalendes 1 ermittelt werden kann. Durch das Okular des Endoskopes ist jedoch die Luftblase 12 im Ringrohr 10 erkennbar, die immer in der 12-Uhr-Position eine Ruhestellung einnimmt. Damit ist die Stellung des Distalendes 1 erkennbar, so daß folgende Erkenntnisse möglich sind:The mode of operation is as follows: The endoscope is placed in a structurally complicated technical cavity, e.g. B. a control valve housing, introduced without the exact location of the distal end 1 can be determined. Through the eyepiece of the endoscope, however, the air bubble 12 can be seen in the ring tube 10 , which always assumes a rest position in the 12 o'clock position. The position of the distal end 1 can thus be recognized, so that the following findings are possible:

  • 1. Die Orientierung im technischen Hohlraum wird erleich­ tert, da die Luftblase immer die 12-Uhr-Position ein­ nimmt. 1. Orientation in the technical cavity will be easier because the air bubble is always at the 12 o'clock position takes.  
  • 2. Der Bildausschnitt des Endoskopes wird durch die An­ ordnung des mit einer Flüssigkeit gefüllten Ringrohres nicht beeinträchtigt.2. The image section of the endoscope is the An order of the ring tube filled with a liquid not affected.
  • 3. Durch die Schutzkappe wird das Ringrohr vor mechanischen Einflüssen ebenfalls geschützt.3. The protective cap protects the ring tube from mechanical Influences also protected.
  • 4. Ein Anbringen eines Wechselobjektivs am Endoskop ist möglich.4. Attaching an interchangeable lens to the endoscope is possible.
