Abstract
Description
Die Erfindung betrifft ein Endoskop zur Beleuchtung und stereo skopischen Bildübertragung des Operationsfeldes, die mechani sche Halterung und Steuerung des Endoskops und eine Vorrichtung zur stereoskopischen Betrachtung der Bilder des Operationsfel des.The invention relates to an endoscope for lighting and stereo scopic image transmission of the operating field, the mechani cal holder and control of the endoscope and a device for stereoscopic viewing of the images of the operating field of.
Stand der Technik der endoskopunterstützten Operationstechnik sind monokulare Endoskope, die mit Hilfe einer Lichtquelle und eines eingebauten Lichtleiters das Operationsfeld beleuchten und über einen zweiten, geordneten Lichtleitfaserbündel das Bild des Operationsfeldes zu einem Okular übertragen, das ent weder mit dem Auge direkt oder über eine Fernsehkamera und an geschlossenen Monitor die Betrachtung des Operationsfeldes ge stattet. Aufgrund der einäugigen Betrachtung des Operationsfel des kann kein räumlicher Eindruck übermittelt werden.State of the art of endoscope-assisted surgical technique are monocular endoscopes that use a light source and Illuminate the surgical field with a built-in light guide and via a second, ordered optical fiber bundle Image of the surgical field transferred to an eyepiece that ent neither with the eye directly or via a television camera and on closed monitor the observation of the surgical field ge equips. Because of the one-eyed view of the surgical field no spatial impression can be given.
Das eingeführte Endoskop muß mit der Hand geführt werden. Da aber der Operateur mit beiden Händen beschäftigt ist, braucht er eine Hilfskraft, die dies für ihn übernimmt und auf Komman dos des Operateurs so führt, daß der Arbeitsbereich des Opera tionsfeldes jeweils im Blickfeld des Operateurs liegt.The inserted endoscope must be guided by hand. There but the surgeon is busy with both hands he is an assistant who does this for him and on command dos des Operateurs so that the working area of the Opera field of operation is in the operator's field of vision.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, das Endoskop der eingangs genannten Art so weiterzubilden, daß durch die Einführung eines weiteren geordneten Lichtleitfaser bündels und dessen räumlicher Anordnung neben dem ersten, zwei Bilder des Operationsfeldes so zu übertragen, daß dem Beobach ter ein räumliches Bild des Operationsfeldes entsteht. Deswei teren wird dieses Stereo-Endoskop in einer mechanischen Vor richtung so gehalten, daß es auf Kommandos des Operateurs auto matisch in allen drei Koordinaten bewegt werden kann. In einem angeschlossenen Binokular kann der Operateur das Operationsfeld stereoskopisch betrachten und so seine Operationen im gewohnten räumlichen Bild besser koordinieren.The present invention is based on the object Develop endoscope of the type mentioned in such a way that by introducing another ordered optical fiber bundle and its spatial arrangement next to the first, two To transfer images of the operating field so that the observer A spatial picture of the operating field is created. Because This stereo endoscope is used in a mechanical front direction so that it is on commands of the operator auto can be moved matically in all three coordinates. In one the surgeon can connect the binocular to the surgical field view stereoscopically and thus perform his operations in the usual coordinate the spatial image better.
Vorteilhafte Weiterbildungen des Erfindungsgedankens sind in den Unteransprüchen angegeben.Advantageous developments of the inventive concept are in specified in the subclaims.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnungen näher erläutert. Dabei zeigt:.An embodiment of the invention is described below of the drawings explained in more detail. It shows:
Fig. 1 das Prinzipbild eines erfindungsgemäß ausgebildeten En doskops zur stereoskopischen Beobachtung des Operati onsfeldes, Fig. 1 illustrates the principle diagram of an inventive design En doskops for stereoscopic observation of the Operati onsfeldes,
Fig. 2 das stereoskopische Endoskop in einer motorisch zu be wegenden Halterung, Fig. 2, the stereoscopic endoscope in a motor-path ends to be mount,
Fig. 3 schematisch die Darbietung der stereoskopischen Bilder über zwei am Kopf des Operateurs angebrachte Monitore zur Gewinnung eines räumlichen Bildes des Operations feldes und das daran befestigte Mikrofon zur Sprach steuerung der motorisch bewegbaren Endoskophalterung. Fig. 3 shows schematically the presentation of the stereoscopic images on two attached to the head of the surgeon monitors to obtain a spatial image of the operating field and the attached microphone for voice control of the motor-driven endoscope holder.
Das Prinzipbild des stereoskopischen Endoskops in Fig. 1 zeigt eine mögliche Ausführungsform, wobei die (1) die Enden der bei den Bildleiter am abgerundeten Ende des Endoskops zeigt. Sie sind umgeben von der Austrittsöffnung (2) des Lichtleiters zur Beleuchtung der Szene. (3) bezeichnet das Mantelrohr des Endoskops, das Licht- und Bildleiter umhüllt und dem Endoskop seine Stabilität verleiht. (4) bezeichnet das Endstück des Endoskops zur räumlichen Aufteilung der beiden Bildleiter auf einen Abstand, der zur Anbringung der Kameras oder der Okulare an den Anschlüssen (5) und (6) notwendig ist. Der Anschluß (7) bildet den Kontakt zum beweglichen Lichtleiter, der mit einer entsprechenden Kaltlichtquelle verbunden ist. The basic diagram of the stereoscopic endoscope in FIG. 1 shows a possible embodiment, the ( 1 ) showing the ends of the image guide at the rounded end of the endoscope. They are surrounded by the exit opening ( 2 ) of the light guide for illuminating the scene. ( 3 ) denotes the jacket tube of the endoscope, which envelops the light and image guide and gives the endoscope its stability. (4) denotes the end piece of the endoscope for the spatial division of the two image guides at a distance which is necessary for attaching the cameras or the eyepieces to the connections ( 5 ) and ( 6 ). The connection ( 7 ) forms the contact to the movable light guide, which is connected to a corresponding cold light source.
Die in Fig. 2 dargestellte mögliche Ausführungsform einer Halterung zeigt den an einem Parallelogramm-Arm (1) befestigten stabilen Rahmen (2) in dem sich eine bewegliche Brücke (3) befindet. Mit dem Spindelmotor (4) wird diese Brücke (3) in X- Richtung bewegt. Sie trägt einen weiteren Spindelmotor (5), der die Endoskop-Halterung (6) in Y-Richtung bewegt. Die Endoskop- Halterung (6) kann ihrerseits mit dem Motor (7) in Z-Richtung bewegt werden. Damit ist das Endoskop in der Halterung (6) in allen drei Koordinaten mit motorischer Hilfe zu bewegen.The possible embodiment of a holder shown in FIG. 2 shows the stable frame ( 2 ) attached to a parallelogram arm ( 1 ) in which there is a movable bridge ( 3 ). This bridge ( 3 ) is moved in the X direction with the spindle motor ( 4 ). It carries a further spindle motor ( 5 ) which moves the endoscope holder ( 6 ) in the Y direction. The endoscope holder ( 6 ) can in turn be moved with the motor ( 7 ) in the Z direction. The endoscope in the holder ( 6 ) can thus be moved in all three coordinates with motor assistance.
Fig. 3 zeigt schematisch die an einem verstellbaren Stirnband (1) angebrachten Monitore (2) zur stereoskopischen Darbietung der Bilder des Operationsfeldes und das am Stirnband befestigte Mikrofon (3) zur Sprachsteuerung der motorisch bewegbaren Endoskophalterung. Fig. 3 shows schematically the attached to an adjustable headband (1) monitors (2) for stereoscopic presentation of the images of the surgical field and attached to the headband microphone (3) for voice control of the motor-driven movable endoscope holder.
