Description

Zu visuellen Beobachtungen in menschlichen Körperhöhlen sind Endoskope im Gebrauch, die mit einer kleinen Niederspannungs-Spezialglühlampe ausgestattet sind. Diese Lichtquellen, die in der Regel mit Überspannung auf Kosten ihrer Lebensdauer betrieben werden, sind zwar für visuelle Beobachtung ausreichend. Für die Endoskope-Photographie ergeben sich dabei jedoch sehr lange Belichtungszeiten, die praktisch untragbar sind. Endoskope-Photographien mit solchen Anordnungen gelingen daher nur in den seltensten Fällen bei besonders günstigen Verhältnissen. Endoscopes are used for visual observations in human body cavities in use, which is equipped with a small, low-voltage special incandescent lamp are. These light sources, usually with overvoltage at the expense of their lifespan are operated are sufficient for visual observation. For endoscope photography However, this results in very long exposure times that are practically unacceptable are. Endoscope photographs with such arrangements are therefore only possible in the rarest cases with particularly favorable conditions.

Man hat daher schon als Lichtquelle für Endoskop-Photographie Funkenstrecken oder Elektronenblitze verwandt. Die Erfindung betrifft eine besonders zweckmäßige und betriebssichere Anordnung zur Endoskop-Photographie mit einer in einem Endoslioprohr angeordneten Blitzröhre. Spark gaps are therefore already used as a light source for endoscopic photography or electronic flashes. The invention relates to a particularly useful one and a reliable arrangement for endoscope photography with one in an endoscope tube arranged flash tube.

Die Erfindung besteht darin, daß das Endoskoprohr die Stromzuführung zur äußeren Elektrode der Blitzröhre bildet und als Kupplungsteil einer Steckerkupplung zum Anschluß an das Zuleitungskabel ausgebildet ist. Dadurch erspart man erheblich an Raum, weil man nicht eine besondere Zuleitung an der Elektronenröhre vorbeizuführen braucht. Durch Erdung des Rohres erreicht man, daß die Entladung in einem Faradayschen Käfig stattfindet, so daß eine Gefährdung durch die Entladungsspannung ausgeschlossen wird. Wenn das Gegenstück des Kupplungsteils am Ende eines an den Spannungsgenerator angeschlossenen Kabels sitzt, kann man dieses Rohr ohne Beschädigungsgefahr gesondert sterilisieren. Das Kabel und das Kupplungsgegenstück brauchen nicht sterilisiert zu werden, wenn man sie in üblicher Weise mit einer sterilen Hülle umgibt. In einem der Kupplungsstücke, vorzugsweise in dem Gegenstück, kann die Zündspule untergebracht werden, um eine lange Zündleitung zu vermeiden. Als Zündelektrode hat sich ein an der Blitzröhre außen angekitteter Draht bewährt. The invention consists in that the endoscope tube is the power supply to the outer electrode of the flash tube and as a coupling part of a plug coupling is designed for connection to the supply cable. This saves a lot of space, because you don't have to run a special lead past the electron tube needs. By earthing the tube, you achieve that the discharge in a Faraday Cage takes place, so that a hazard from the discharge voltage is excluded will. When the counterpart of the coupling part at the end of a to the voltage generator connected cable, you can separate this pipe without risk of damage sterilize. The cable and the coupling counterpart do not need to be sterilized when it is surrounded by a sterile envelope in the usual way. In one the coupling pieces, preferably in the counterpart, can accommodate the ignition coil to avoid a long ignition lead. A has been used as the ignition electrode Wire cemented on the outside of the flash tube has proven its worth.

Als Ausführungsbeispiel der Erfindung ist in der Zeichnung (Abb. I und 2) schematisch ein Endoskopblitzgerät dargestellt, dessen Rohr neben dem Photo-Endoskop an Stelle einer Operationsvorrichtung in die Brusthöhle eingeführt wird. As an embodiment of the invention is shown in the drawing (Fig. I and 2) an endoscope flash device is shown schematically, the tube of which is next to the photo endoscope is inserted into the chest cavity in place of a surgical device.

Das Gerät besteht aus einem Spannungsgenerator I, der in üblicher Weise die Speicherkondensatoren enthält, und einem durch ein Kabel 2 angeschlossenen Leuchtgerät 3. Das Leuchtgerät hat die Form eines wenige Millimeter dicken Rohres 3', das an einem Ende 3" verdickt und mit Kontaktsteckern versehen ist. Das Kupplungsgegenstück 4 am Ende des Kabels 2 enthält die Zündspule 5 und einen Zündkontakt 6. The device consists of a voltage generator I, which in usual Way contains the storage capacitors, and one connected by a cable 2 Illuminator 3. The illuminator has the shape of a tube a few millimeters thick 3 ', which is 3 "thick at one end and provided with contact plugs. The coupling counterpart 4 at the end of the cable 2 contains the ignition coil 5 and an ignition contact 6.

Der Kopf des Leuchtgerätes 3 ist in Abb. 2 geschnitten dargestellt. Vor einem Fenster 7, das durch eine von innen eingekittete durchsichtige Scheibe 8 abgedeckt ist, liegt eine kleine längliche Elektronenröhre 9. Die äußere Elektrode IO ist mit dem Metallrohr 3' unmittelbar verbunden. An die innere Elektrode II ist ein isolierter Zuleitungsdraht 12 angelötet. Um den Absaugstutzen I3 der Elektronenröhreg ist ein dünner Zünddraht I4 herumgeschlungen, der als Zündelektrode an die Elektronenröhre g außen angekittet ist. Der Zünddraht 14 ist ebenfalls isoliert zum Stecker 3" geführt. The head of the lighting device 3 is shown in section in FIG. In front of a window 7 through a transparent pane cemented in from the inside 8 is covered, lies a small elongated electron tube 9. The outer electrode IO is directly connected to the metal pipe 3 '. To the inner electrode II is an insulated lead wire 12 is soldered on. To the suction nozzle I3 of the electron tube a thin ignition wire I4 is looped around, which acts as an ignition electrode on the electron tube g is cemented on the outside. The ignition wire 14 is also guided to the plug 3 ″ in an insulated manner.

Die Einschaltung des Gerätes erfolgt am Hauptschalter 15 des Spannungsgenerators I. Die Auslösung des Blitzes kann in bekannter Weise mit dem Kameraverschluß synchronisiert sein oder durch den Zündkontakt 6 erfolgen, der natürlich auch am Spannungsgenerator I angebracht sein kann. Naturgemäß muß für eine gute Erdung des Leuchtgerätes 3 gesorgt werden. The device is switched on at the main switch 15 of the voltage generator I. The triggering of the flash can be synchronized in a known manner with the camera shutter his or through the ignition contact 6, which of course also on the voltage generator I can be appropriate. Naturally, for a good grounding of the lighting device 3 to be taken care of.
