Description

Die Erfindung betrifft ein endoskopisches Gerätesystem, vor­ zugsweise für die medizinische Anwendung, mit dem Hohlräume optisch untersucht werden können. Heute sind derartige Endo­ skopsysteme üblicherweise als Videoendoskope ausgeführt, das heißt, sie bestehen aus einer handgeführten, bildaufnehmenden Endoskopsonde und einem externen Bildwiedergabegerät. Die En­ doskopsonde weist dabei einen distalen länglichen Schaft und ein proximales Griffstück auf. Die Signalübertragung von der Endoskopsonde zum Bildwiedergabegerät bzw. zu einer externen Elektronik für die Bildsignalbearbeitung erfolgt drahtgebun­ den mittels Signalleitungen. Derartige Endoskopsysteme sind unter anderem in den DE 30 39 523 A1 und DE 299 19 542 U1 be­ schrieben.The invention relates to an endoscopic device system preferably for medical use, with the cavities can be examined optically. Today these are endo Scope systems usually run as video endoscopes Means they consist of a hand-held, image-taking Endoscope probe and an external image display device. The En Doskopsonde has a distal elongated shaft and a proximal handle. The signal transmission from the Endoscope probe to the image display device or to an external one Electronics for image signal processing are wired by means of signal lines. Such endoscope systems are inter alia in DE 30 39 523 A1 and DE 299 19 542 U1 wrote.

Zur Ausleuchtung des Objektfeldes ist es üblich, die erfor­ derliche Lichtleistung über Lichtleiter von einer externen Lichtquelle, z. B. Xenon-, Metall-Halid- oder Halogenlampen, in den Bereich der Bildaufnahmeoptik zu übertragen. Aus den DE 296 098 357 U1 und DE 43 01 604 A1 sind solche Lösungen bekannt. In den DE 298 12 048 U1, DE 296 13 103 U1 und DE 299 10 795 U1 sind Systeme beschrieben, bei welchen die Licht­ quellen, lichtemittierende Dioden, Kleinlampen, Elektrolumi­ niszenzlampen in oder an der Endoskopsonde angeordnet sind, wobei diese Lichtquellen über Kabel von einer externen Strom­ versorgungseinheit gespeist werden.To illuminate the object field, it is common to light output via light guide from an external Light source, e.g. B. xenon, metal halide or halogen lamps, to transfer in the field of image recording optics. From the DE 296 098 357 U1 and DE 43 01 604 A1 are such solutions known. In DE 298 12 048 U1, DE 296 13 103 U1 and DE 299 10 795 U1 systems are described in which the light sources, light-emitting diodes, small lamps, electrolumines fluorescent lamps are arranged in or on the endoscope probe, taking these light sources through cables from an external power supply unit are fed.

Bei allen bekannten gattungsgemäßen Endoskopsystemen ist nachteilig, daß die erforderlichen Signal- und Versorgungs­ leitungen den Arbeitsradius und die Beweglichkeit sehr ein­ schränken und sogar ein Unfallrisiko darstellen können. Bei medizinischen Anwendungen stellen die Leitungen ein Risiko hinsichtlich der Sterilität dar. Außerdem führt die mechanische Beanspruchung der Leitungen zu einer hohen Reparaturan­ fälligkeit.In all known generic endoscope systems disadvantageous that the necessary signal and supply leads the working radius and mobility very limit and even pose an accident risk. at medical applications put the lines at risk regarding sterility. In addition, the mechanical  Strain on the lines to a high repair Due date.

Es ist daher Aufgabe der Erfindung, ein endoskopisches Gerä­ tesystem zu schaffen, welches gegenüber dem bekannten Stand der Technik einen höheren Bedienkomfort aufweist und einen geringeren Wartungs- und Reparaturaufwand erfordert. Bei me­ dizinischen Anwendungen soll das Unfallrisiko im Umgang mit dem Instrument sowie das Sterilitätsrisiko gesenkt werden.It is therefore an object of the invention to provide an endoscopic device tesystem to create, which compared to the known state the technology has a higher ease of use and one requires less maintenance and repair. At me medical applications is intended to reduce the risk of accidents when handling the instrument and the risk of sterility.

Diese Aufgabe wird durch ein endoskopisches Gerätesystem mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Aus­ gestaltungen der Erfindung sind in den Unteransprüchen ange­ geben.This task is accomplished through an endoscopic device system solved the features of claim 1.

Fig. 1 die Prinzipdarstellung einer Endoskopsonde Fig. 1 shows the schematic diagram of an endoscope probe

Fig. 2 die Prinzipdarstellung des gesamten Gerätesystems Fig. 2 shows the schematic diagram of the entire device system

Das endoskopische Gerätesystem weist die Endoskopsonde 1 und das externe Bildwiedergabegerät 5 mit Empfangseinheit 4 auf. Am distalen Ende der Endoskopsonde 1 befindet sich die Optik 7, wobei die Bildaufnehmereinheit 6 vorteilhaft unmittelbar hinter der Optik 7 angeordnet ist. Die Lichtquellen 9 in Form von LEDs sind im Inneren der Endoskopsonde 1 verteilt ange­ ordnet. Im Ausführungsbeispiel sind auf den ungekapselten LEDs direkt lichtleitende Fasern 10 aufgesetzt, welche das Licht zur Ausleuchtung des Objektfeldes zum distalen Ende der Endoskopsonde 1 leiten. Weiterhin sind im Inneren der Endo­ skopsonde 1 die aus Stromversorgungselektronik 11 und Akkumu­ latoren 12 bestehende Stromversorgungseinheit 2, die Sende­ einheit 3 und die Signalverarbeitungseinheit 13 integriert. Zum Endoskopsystem gehört außerdem die externe Empfangsein­ heit 4 mit zugehörigem Bildwiedergabegerät 5 sowie die exter­ ne Ladeeinheit 8. In einer besonders vorteilhaften Ausgestal­ tung des erfindungsgemäßen endoskopischen Gerätesystems ist das Bildwiedergabegerät als Videobrille ausgebildet.The endoscopic device system has the endoscope probe 1 and the external image display device 5 with the receiving unit 4 . The optics 7 are located at the distal end of the endoscope probe 1 , the image pickup unit 6 advantageously being arranged directly behind the optics 7 . The light sources 9 in the form of LEDs are arranged inside the endoscope probe 1 . In the exemplary embodiment, light-guiding fibers 10 are placed directly on the unencapsulated LEDs, which guide the light for illuminating the object field to the distal end of the endoscope probe 1 . Furthermore, the power supply unit 2 , the transmission unit 3 and the signal processing unit 13 are integrated in the interior of the endoscope scope 1, the power supply electronics 11 and accumulators 12 . The endoscope system also includes the external receiver unit 4 with associated image display device 5 and the external charging unit 8 . In a particularly advantageous embodiment of the endoscopic device system according to the invention, the image display device is designed as video glasses.

Aus Sterilitätsgründen erfolgt das Laden der Akkumulatoren 12 auf kontaktlosem Weg. Dazu wird die Ladeenergie induktiv von der externen Ladeeinheit 8 zur Stromversorgungselektronik 11 der Stromversorgungseinheit 2 übertragen. Die Stromversor­ gungseinheit 2 versorgt sowohl die Lichtquellen 9 als auch die Sendeeinheit 3, die Signalverarbeitungseinheit 13 und die Bildaufnehmereinheit 6. Das Objektfeld wird mittels der Optik 7 auf die Bildaufnehmereinheit 6 abgebildet. Die erzeugten Bildsignale werden zur Signalverarbeitungseinheit 13 weiter­ geleitet und dort bearbeitet. In der Signalverarbeitungsein­ heit 13 erfolgt vorteilhafterweise eine Komprimierung der Bilddaten und/oder eine Reduktion der für die Bildübertragung erforderlichen Bandbreite. Die aufbereiteten Bildsignale wer­ den von der Sendeeinheit 3 drahtlos zur externen Empfangsein­ heit 4 des Bildwiedergabegerätes 5 übertragen. Dazu eignen sich sowohl Funk- als auch Infrarotübertragung. Zu favorisie­ ren ist eine digital codierte Signalübertragung, wie sie zum Beispiel in der Blootooth-Technologie standardisiert ist. In einem nicht dargestellten Ausführungsbeispiel ist in der En­ doskopsonde eine Empfangseinheit zum drahtlosen Empfang von Signalen zur Steuerung der Objektfeldbeleuchtung, der Bild­ aufnehmereinheit oder anderer Funktionen integriert. In wei­ teren Ausführungsvarianten kann das endoskopische Gerätesy­ stem mit mehreren Bildsensoren für die 3-D-Endoskopie oder die 3-Chip-Technik mit zwei oder mehr Bildsensoren ausgestat­ tet sein. For reasons of sterility, the batteries 12 are charged in a contactless manner. For this purpose, the charging energy is transmitted inductively from the external charging unit 8 to the power supply electronics 11 of the power supply unit 2 . The Stromversor supply unit 2 supplies both the light sources 9 and the transmitter unit 3 , the signal processing unit 13 and the image pickup unit 6th The object field is imaged on the image pickup unit 6 by means of the optics 7 . The generated image signals are forwarded to the signal processing unit 13 and processed there. The signal processing unit 13 advantageously compresses the image data and / or reduces the bandwidth required for image transmission. The processed image signals are transmitted wirelessly from the transmitter unit 3 to the external receiver unit 4 of the image display device 5 . Both radio and infrared transmission are suitable for this. Digitally coded signal transmission is preferred, as is standardized in blootooth technology, for example. In one embodiment, not shown, a receiver unit for wireless reception of signals for controlling the object field lighting, the image pickup unit or other functions is integrated in the endoscopic probe. In further embodiment variants, the endoscopic device system can be equipped with several image sensors for 3-D endoscopy or 3-chip technology with two or more image sensors.
