Description
Vorrichtung an Gastroskopen oder anderen Endoskopen zur Untersuchung, Photographie oder Kinematographie Das Gebrauchsmuster betrifft eine Vorrichtung an Gastroskopen oder anderen Endoskopen zur Untersuchung, Photographie oder Kinematographie mittels eines teleskopischen Sehrohres, das im Bereich des distalen Endes eines Einführungsschaftes und einer Lichtquelle endigt.Device on gastroscopes or other endoscopes for examination, Photography or cinematography The utility model relates to a device on gastroscopes or other endoscopes for examination, photography or cinematography by means of a telescopic periscope, which in the area of the distal end of a Introductory shaft and a light source ends.
Bei den bekannten starren oder biegsamen Gastroskopen ist im Bereich des Schaftendes die Lichtquelle aus konstruktiven Gründen vor dem Objektiv des teleskopischen Sehrohres angeordnet, und zwar beträgt der Abstand etwa 15 bis 20 mm. Dieser Abstand ist an sich für die Beleuchtung des Blickfeldes ausreichend, wenn das Objekt, beispielsweise die Magenwand, genügend weit vom eingeführten Instrument entfernt ist.With the known rigid or flexible gastroscopes is in the range of the shaft end the light source for structural reasons in front of the lens of the telescopic Periscope arranged, namely the distance is about 15 to 20 mm. This distance is in and of itself sufficient for illuminating the field of view if the object is, for example the stomach wall is sufficiently far from the inserted instrument.
Die Erfahrungnbei der Magenuntersuchung lehren jedoch, daß eine ausreichende Beleuchtung des Blickfeldes nicht möglich ist, wenn die Entfernung des Objektives und der Lichtquelle von der Magenwand kleiner ist als 12 mm, wie dies beispielsweise bei der Untersuchung der kleinen Kurvatur des Magens aus anatomischen Gründen der Fall ist. Dort liegen Objektiv und Lichtquelle des eingeführten Gastroskopes dicht an der Magenwand, weshalb die Lichtstrahlen nicht in das Blickfeld des Untersuchenden gelangen können. Diese Magenpartie, die als"blinde Stelle"bezeichnet wird, kann daher weder untersucht noch photographiert werden, obwohl sie für die Diagnostik besondere Bedeutung hat.However, experience from gastric examination teaches that sufficient Illumination of the field of view is not possible when the distance of the lens and the light source from the stomach wall is smaller than 12 mm, such as this for example when examining the small Curvature of the stomach from anatomical Reasons is the case. The objective and light source of the inserted gastroscope are located there close to the stomach wall, which is why the light rays are not in the field of vision of the examiner can get. This part of the stomach, known as the "blind spot", can therefore neither examined nor photographed, although they are used for diagnosis has special meaning.
Diesem Mangel wird mittels der Vorrichtung gemäß dem Gebrauchsmuster
dadurch abgeholfen, daß die Sehachse des teleskopischen Sehrohres, bzw. dessen Objektives
Da die Sehachse und die Lichtachse im Prisma vereinigt sind, kann auch eine unmittelbar am Instrument anliegende Magenwand unter günstigen Lichtverhältnissen untersucht und photographiert werden, Auf der Zeichnung ist der Gegenstand der Neuerung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigen die beiden Figuren das Schaftende eines Gastroskopes in schaubildlicher Darstellungsweise und teilweise geschnitten in verschiedenen, um 900 zueinander versetzten Stellungen.Since the visual axis and the light axis are united in the prism, can also a stomach wall lying directly on the instrument under favorable lighting conditions be examined and photographed, the subject of innovation is on the drawing illustrated in one embodiment, namely show the two figures the shaft end of a gastroscope in a diagrammatic representation and partially cut in various positions offset by 900 to one another.
Im dargestellten Ausführungsbeispiel sind der Schaft eines Gastroskopes mit 1, seine elastische Gummispitze mit 2, der mit einer proximalen Lichtquelle verbundene lichtleitende Stab mit 3, das teleskopische Sehrohr mit 4, das am Ende dieses Sehrohres 4 angeordnete Objektiv mit 5 und das Prisma zur Ablenkung der Sehachse und der Lichtachse mit 6 bezeichnet.In the illustrated embodiment, the shaft of a gastroscope with 1, its elastic rubber tip with 2, the one with a proximal light source connected light-guiding rod with 3, the telescopic periscope with 4, the one at the end this periscope 4 arranged lens with 5 and the prism for deflecting the visual axis and the light axis is denoted by 6.
Der lichtleitende Stab 3 kann durch eine vor dem Prisma 6 angeordnete Glühlampe ersetzt sein. Einem biegsamen Schaft 1 kann ein biegsamer Lichtleiter 3 zugeordnet sein.The light-conducting rod 3 can be arranged in front of the prism 6 by a Light bulb must be replaced. A flexible shaft 1 can be a flexible light guide 3 must be assigned.
Die Vorrichtung kann bei Gastroskopen mit starrem oder biegsamem Schaft und auch bei anderen Endoskopen Anwendung finden.The device can be used in gastroscopes with a rigid or flexible shaft and can also be used with other endoscopes.
