Mit Hilfe einer solchen Kamera und eines Endoskops können minimal invasive Eingriffe in einem Operationssaal durchgeführt werden, wie beispielsweise die visuelle Inspektion innerer Organe oder die Entnahme von Gewebeproben. Ähnliche Bildübertragungssysteme sind für die industrielle Endoskopie verfügbar, um technische Aggregate inspizieren zu können. Mit derartigen Endoskopen sind dann Inspektionen zum Beispiel innerhalb eines Flugzeugtriebwerkes ohne dessen Demontage möglich. Hat man das defekte oder verschlissene Teil im Flugzeugtriebwerk gefunden, dann kann gezielt demontiert und in Folge dessen kostengünstig und schnell repariert werden. Die vorgenannten Bildübertragungssysteme zeichnen sich durch einen erhöhten Energiebedarf und die hohe zu übertragende Datenmenge an Bilddaten aus. Dabei werden die Energieversorgung der endoskopischen Kamera sowie die beim Einsatz generierten Bildinformationen zur Darstellung auf einem Bildschirm oder zur Übermittlung in eine abgesetzte Datenbank gleichzeitig über ein einziges für die Energie- und Datenübertragung ausgelegtes Kabel bewerkstelligt. Dieses Kabel zeichnet sich an seinen beiden freien Enden jeweils durch einen aufwändigen speziellen mehrpoligen Stecker aus, der dazu ausgelegt ist, die Kabelverbindung mit einem Steuergerät mit Datenbank, beispielsweise dem Image 1 hub HD von Karl Storz, zu verbinden.For a variety of endoscopic applications digital image transfer systems are used, such as the autoclavable endoscopic IMAGE 1 digital camera by Karl Storz.

In einer besonders vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die beiden Stecker der ersten und der weiteren flexiblen Leitung des erfindungsgemäßen Kabels als USB-Stecker ausgeführt sind. Dies hat den Vorteil, dass das erfindungsgemäße elektrische Kabel zur Verbindung mit standardisierten USB-Anschlüssen ausgestattete elektronische Geräte geeignet ist. Das erfindungsgemäße elektrische Kabel kann dabei für eine Benutzung mit einem oder mehreren solchen elektronischen Geräten auf diese standardisierten USB-Anschlüsse aufgesteckt werden oder entfernt werden. Ein zugehöriges medizinisches Endoskopie- und Dokumentationssystem oder Videodatensysteme wird daher erfindungsgemäß mit zwei USB-Anschlüssen versehen.In a particularly advantageous embodiment of the invention, it is provided that the two plugs of the first and the further flexible line of the cable according to the invention are designed as USB plugs. This has the advantage that the electrical cable according to the invention is suitable for connection to standardized USB ports equipped electronic devices. The electrical cable according to the invention can be plugged or removed for use with one or more such electronic devices on these standardized USB ports. An associated medical endoscopy and documentation system or video data systems is therefore provided according to the invention with two USB ports.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Stecker, die zur gemeinsamen Kontaktierung mit einem elektronischen Gerät dienen, wenigstens 4 Kontakte aufweisen, wobei mindestens 2 Kontakte mit jeweils einem Datenleiter verbunden sind und mindestens zwei 2 Kontakte mit jeweils einem Energieübertragungsleiter elektrisch verbunden sind. Dies ermöglicht die Realisierung des erfindungsgemäßen Kabels in Anlehnung an die USB-Norm. Erfindungsgemäß mündet dabei die weitere flexible Leitung in den Stecker der ersten flexiblen Leitung, sodass durch diese Anordnung und Verbindung der ersten und weiteren flexiblen Leitung ein Y-förmiges Kabel gebildet wird. Diese erfindungsgemäße Verbindung erweist sich als besonders vorteilhaft, weil dadurch eine feste und sichere Verbindung zwischen dem Stecker der ersten flexiblen Leitung und der weiteren flexiblen Leitung hergestellt ist.In a further preferred embodiment of the invention it is provided that the plug, which serve for the common contact with an electronic device, have at least 4 contacts, wherein at least 2 contacts are each connected to a data conductor and electrically connected at least two contacts, each with a power transmission conductor are. This allows the realization of the cable according to the invention based on the USB standard. According to the invention, the further flexible line opens into the plug of the first flexible line, so that a Y-shaped cable is formed by this arrangement and connection of the first and further flexible line. This compound according to the invention proves to be particularly advantageous, because thereby a firm and secure connection between the plug of the first flexible line and the other flexible line is made.

Darüber hinaus wird von einem Monteur aufgrund der korrespondierenden asymmetrischen Strukturen im Aufbau der beiden Stecker sofort bemerkt, ob eine korrekte Montage der Stecker erfolgt ist oder nicht. Mit der vorbeschriebenen Bauweise der Stecker ist auch eine automatisierte Montage der Stecker leichter möglich. Ein weiterer besonderer Vorteil ist darin zu sehen, dass mittels des erfindungsgemäßen Kabels auf die Verwendung von zwei getrennten insbesondere standardmäßigen USB-Kabel vermieden werden kann und damit die Gefahr verringert wird, dass sich Personen mit einem der mehreren lose liegenden USB-Kabel verheddern oder darüber stolpern und/oder einen Kabelabriss herbeiführen.In addition, it is immediately noticed by a fitter due to the corresponding asymmetric structures in the structure of the two plugs, whether a correct installation of the plug has been made or not. With the above-described construction of the plug an automated assembly of the plug is also possible. Another particular advantage is the fact that by means of the cable according to the invention to the use of two separate, especially standard, USB cables can be avoided, reducing the risk of people becoming entangled or stumbling with one of the several loose USB cables and / or causing cable breakage.

In einer besonders bevorzugten Ausführungsform des erfindungsgemäßen elektrischen Kabels befinden sich in einem Stecker zu dem bevorzugten Videodatensystem der ersten flexiblen Leitung Kontaktflächen, insbesondere Lötflächen, zur elektrischen Kontaktierung von Daten- und Energieübertragungsleiter. An diesen Lötflächen sind wenigstens 2 Datenleiter und wenigstens 2 Energieübertragungsleiter der weiteren flexiblen Leitung und mit wenigstens 2 Datenleiter und wenigstens 2 Energieübertragungsleiter der ersten flexiblen Leitung elektrisch leitend verbunden. Dabei sind die im Stecker angeordneten Lötflächen mit den korrespondierenden Leitern mittels geeignetem Lotmaterial elektrisch leitend und mechanisch fest verbunden. Diese erfindungsgemäße Verbindung und vorbeschriebenen Bauweise erweist sich als besonders vorteilhaft, da dadurch eine Lötung einfach und automatisiert vorgenommen werden kann und eine mechanisch zuverlässige und haltbare Verbindung zwischen den einzelnen Leitern und den Lötflächen des Steckers hergestellt wird, so dass nach dieser Verbindung ein schon fast fertiger Stecker zur Verfügung steht.In a particularly preferred embodiment of the electrical cable according to the invention are in a connector to the preferred video data system of the first flexible line contact surfaces, in particular solder pads, for electrical contacting of data and power transmission conductor. At least two data conductors and at least two energy transmission conductors of the further flexible conduit and at least two data conductors and at least two energy transmission conductors of the first flexible conduit are electrically conductively connected to these pads. In this case, the soldering surfaces arranged in the plug are electrically conductively and mechanically firmly connected to the corresponding conductors by means of suitable soldering material. This compound of the invention and the above construction proves to be particularly advantageous, since a soldering can be made simple and automated and a mechanically reliable and durable connection between the individual conductors and the solder pads of the connector is made, so that after this connection an almost finished Plug is available.

Neben dem Verlöten der zum Verbinden der Kontaktflächen mit Leitern hat sich auch die Möglichkeit, die Leiter durch Crimpen elektrisch und mechanisch miteinander zu verbinden, bewährt. Diese stellt eine produktionstechnisch einfacher herzustellende Verbindung dar, die den gewissen Nachteil hat, dass sich die Verbindung bei sehr rauen Umgebungsbedingungen, wie insbesondere starke Vibrationen, lösen kann.In addition to the soldering to connect the contact surfaces with conductors and the ability to electrically and mechanically connect the conductors by crimping, has proven itself. This represents a production technology simpler to produce connection, which has the certain disadvantage that the connection in very harsh environmental conditions, in particular strong vibrations, can solve.

In besonders vorteilhafter Weise wird der Stecker aus elektrisch nicht leitfähigem Material, zum Beispiel in einem Kunststoff-Spritzgussverfahren hergestellt. Gerade durch die Wahl eines sterilisierbaren Kunststoffs gelingt es ein insgesamt sterilisierbares erfindungsgemäßes elektrisches Kabel zu schaffen, dass darüber hinaus einfach herzustellen und auch sicher insbesondere maschinell montierbar ausgebildet ist.In a particularly advantageous manner, the plug is made of electrically non-conductive material, for example in a plastic injection molding process. Especially by the choice of a sterilizable plastic, it is possible to create a total sterilizable electrical cable according to the invention that, moreover, is simple to manufacture and is also designed to be particularly secure, in particular, mechanically mountable.

In einer weiteren besonders bevorzugten Ausführungsform des erfindungsgemäßen elektrischen Kabels ist vorgesehen, dass die erste flexible Leitung mit wenigsten 4 Datenleiter und wenigsten 4 Energieübertragungsleiter durchzogen ist und dass diese Leiter mit einem der Stecker der ersten flexiblen Leitung elektrisch leitend verbunden sind, wobei 2 der wenigsten 4 Datenleiter und 2 der wenigstens 4 Energieübertragungsleiter der ersten flexiblen Leitung mit dem anderen Stecker der ersten flexiblen Leitung elektrisch leitend verbunden sind. Besonders wesentlich ist ferner, dass 2 der wenigsten 4 Datenleiter und 2 der wenigstens 4 Energieübertragungsleiter der ersten flexiblen Leitung über die Lötflächen mit dem Stecker der weiteren flexiblen Leitung elektrisch leitend verbunden sind. Durch die erfindungsgemäße Anordnung und Führung der Daten- und Energieübertragungsleiter in der ersten und weiteren flexiblen Leitung des erfindungsgemäßen Y-förmigen elektrischen Kabels und Steckern an den 3 Enden ist es sichergestellt, dass zwischen den beiden Steckern des erfindungsgemäßen elektrischen Kabels auf einer Seite Energie und Daten zu dem anderen Stecker auf der anderen Seite übertragen bzw. ausgetauscht werden kann. Dadurch wird es ermöglicht, dass auf einfache und sichere Weise über das erfindungsgemäße Kabel miteinander verbundene elektronische Geräte (sowohl) gleichzeitig, zeitlich versetzt oder prioritätsgesteuert Energie and auch Daten übertragen werden können, und über die weitere flexible Leitung ein erhöhter Daten- und Energie-übertragungsbedarf befriedigt werden kann, als, beispielsweise durch mehrere standardmäßige Kabel nach dem USB-Standard übertragen werden kann.In a further particularly preferred embodiment of the electric cable according to the invention, it is provided that the first flexible line is traversed with at least 4 data conductors and at least 4 energy transmission conductors and that these conductors are electrically conductively connected to one of the plugs of the first flexible conduit, with 2 of the fewest 4 Data conductor and 2 of the at least 4 power transmission conductors of the first flexible conduit are electrically connected to the other connector of the first flexible conduit. It is also particularly important that 2 of the least 4 data conductors and 2 of the at least 4 energy transmission conductors of the first flexible line are electrically conductively connected via the soldering surfaces to the plug of the further flexible line. The inventive arrangement and guidance of the data and power transmission conductors in the first and further flexible line of the invention Y-shaped electrical cable and plugs at the 3 ends, it is ensured that between the two connectors of the electric cable according to the invention on one side energy and data can be transferred or replaced to the other connector on the other side. This makes it possible that in a simple and secure manner via the cable according to the invention interconnected electronic devices (both) simultaneously, temporally offset or priority-controlled energy and data can be transmitted, and the further flexible line an increased data and energy transmission needs can be satisfied than, for example, by several standard cables to the USB standard can be transmitted.

Vorzugsweise ist das erfindungsgemäße elektrische Kabel mit der ersten flexiblen Leitung so ausgebildet, dass es fest mit einer endoskopischen Kamera elektrisch und mechanisch verbunden sein kann. Hierbei erfolgt die feste Verbindung durch Verlöten, Crimpen, Klemmen oder Verschrauben entgegen der leicht lösbaren Verbindung durch einen abziehbaren bzw. aufsteckbaren Stecker. Bei dieser Ausgestaltung der Erfindung sind die durch die erste flexible Leitung geführten wenigstens 4 Energie- und wenigstens 4 Datenübertragungsleiter fest mit zwei im Gehäuse der endoskopischen Kamera untergebrachten Platinen angeschlossen und elektrisch verbunden. Dabei ist jede Platine der zwei Platinen einer endoskopischen Kamera mit wenigstens 2 Datenleiter und wenigstens 2 Energieübertragungsleitern elektrisch und mechanisch fest verbunden. Eine der Platinen stellt vorzugsweise das main board und die andere das converter board dar. Durch diese Aufteilung der Datenleiter und der Energieübertragungsleiter auf die zwei Platinen ist sichergestellt, dass jede Platine für sich ausreichend Energie zugeführt und ausreichend Daten übertragen bekommen können. Dabei hat es sich als sehr vorteilhaft herausgestellt die Funktionalitäten in der endoskopischen Kamera erfindungsgemäß so auf zwei Platinen zu verteilen, dass diese bezüglich Verteilung des elektrischen Energiebedarfs und des Datenübertragungsbedarf ausgeglichen ausgebildet sind. Dadurch ist ein sehr effizientes Kameradesign mit dieser Aufteilung der Funktionalitäten auf zwei Platinen ermöglicht, was sich einerseits in einer besseren kompakteren räumlichen Ausbildung des Kameradesigns, einem besseren thermischen Design wie auch in einem besseren elektronischen Design widerspiegelt. Gerade die Ausbildung mit dem separaten converter board, das die Wandlung eines analogen Bilddatenstroms in einen digitalen Bilddatenstrom ggfs. mit einer gewissen Bildverarbeitung zeigt und sich durch einen ausgesprochen elektrischen Energiebedarf, wie auch Datentransferbedarf auszeichnet, erweist sich gerade im Hinblick auf die räumliche Anordnung in der Kamera sowie im Hinblick auf die Probleme der Elektromagnetischen Verträglichkeit (EMV) mit der Zu- und Ableitung von Daten und elektrischer Energie als sehr vorteilhaft. Durch die separate Ausbildung einer weiteren Platine wie das main board, das die zentralen Steuerfunktionen, einen Teil der Bildverarbeitung mit dem Bildprozessor wahrnimmt wie auch bevorzugt elektromotorische Antriebe mit Energie versorgt und zusätzlich die Bedienung der Kamera mit ihrem Mann-Maschine-Interface überwacht, ist ein besonders vorteilhaftes Design der Kamera mit zugehörigem erfindungsgemäßen Kabel geschaffen das die erforderliche hohe Energieversorgung und Datenübertragungsrate sicherstellt.Preferably, the electrical cable according to the invention with the first flexible line is designed so that it can be firmly connected to an endoscopic camera electrically and mechanically. Here, the fixed connection by soldering, crimping, clamping or screwing takes place against the easily detachable connection through a removable or plug-in connector. In this embodiment of the invention, the at least 4 power and at least 4 data transmission conductors routed through the first flexible cable are firmly connected and electrically connected to two boards accommodated in the housing of the endoscopic camera. In this case, each board of the two boards of an endoscopic camera with at least 2 data conductors and at least 2 power transmission conductors is electrically and mechanically firmly connected. One of the boards is preferably the main board and the other the converter board. This division of the data conductors and the power transmission conductors on the two boards ensures that each board can be supplied with sufficient energy and sufficient data can be transferred. It has been found to be very advantageous to distribute the functionalities in the endoscopic camera according to the invention on two boards so that they are designed to be balanced with respect to distribution of the electrical energy requirement and the data transfer requirement. This allows a very efficient camera design with this division of functionality on two boards, which is reflected on the one hand in a better compact spatial design of the camera design, a better thermal design as well as in a better electronic design. Especially the training with the separate converter board, which shows the conversion of an analogue image data stream into a digital image data stream possibly with a certain image processing and is characterized by a very electrical energy demand, as well as data transfer needs, proves especially in view of the spatial arrangement in the Camera as well as in view of the problems of electromagnetic compatibility (EMC) with the supply and discharge of data and electrical energy as very beneficial. The separate design of another board such as the main board, which performs the central control functions, a part of the image processing with the image processor as well as preferably provides electric motor drives with energy and additionally monitors the operation of the camera with their man-machine interface, is a created particularly advantageous design of the camera with associated cable according to the invention which ensures the required high power supply and data transmission rate.

Ein weiterer Vorteil der festen Verbindung der ersten flexiblen Leitung mit einem elektrischen Gerät, beispielsweise einer endoskopischen Kamera, ist darin zu sehen, dass im Einsatz eine sichere insbesondere mechanisch sichere Verbindung zwischen dem elektrischen Kabel und der endoskopischen Kamera gewährleistet ist. Da das elektrische Kabel fest mit der endoskopischen Kamera, fest verbunden ist, besteht keine Gefahr, dass das elektrische Kabel während des Betriebs der endoskopischen Kamera durch einen Zug aus der endoskopischen Kamera gezogen werden kann. Dies kann insbesondere bei medizinischen Notfalleingriffen lebensnotwendig sein, da hier der Arzt fortlaufend und ununterbrochen über die einzelnen Schritte seines operativen Eingriffs direkt oder indirekt über ein über das erfindungsgemäße Kabel angeschlossenes Display informiert sein muß. Zum anderen wird durch die feste Verbindung des erfindungsgemäßen elektrischen Kabels mit der endoskopischen Kamera eine zuverlässige Übertragung der Bilddaten für die Dokumentation und Archivierung beispielsweise in ein medizinisches Videodatensystem ermöglicht. Erst hierdurch ist es möglich, dem Patienten nach der Operation die einzelnen Schritte des Eingriffs zu erklären bzw. - falls notwendig - mit der bildgebenden Darstellung weitere Schritte für einen weiteren Eingriff zu planen.Another advantage of the fixed connection of the first flexible cable with an electrical device, such as an endoscopic camera, is the fact that in use a secure, in particular mechanically secure connection between the electrical cable and the endoscopic camera is ensured. Since the electrical cable is firmly connected to the endoscopic camera, there is no danger that the electrical cable can be pulled out of the endoscopic camera during the operation of the endoscopic camera by a pull. This can be especially true in medical Emergency be vital, since the doctor must be continuously and continuously informed about the individual steps of his surgical intervention directly or indirectly via a connected via the cable according to the invention display. On the other hand, the fixed connection of the electrical cable according to the invention with the endoscopic camera enables reliable transmission of the image data for documentation and archiving, for example, into a medical video data system. Only then is it possible to explain the individual steps of the procedure to the patient after the operation or, if necessary, to plan further steps for further intervention with the imaging.

Alternativ sieht eine andere bevorzugte erfindungsgemäße Ausführung vor anstelle der festen Verbindung zu den Platinen der endoskopischen Kamera eine lösbare Verbindung z.B. in Form eines Stecker mit Steckeraufnahme an der Kamera vorzusehen um die verlässliche Kontaktierung des erfindungsgemäßen elektrischen Kabels über die erste flexible Leitung zu erreichen. Dabei ist der Stecker zur besseren Sicherheit im Medizinischen Umfeld bevorzugt mit Sicherungselementen wie Widerhaken oder Fixiermittel versehen, die ein ungewolltes Lösen des Steckers aus der Aufnahme verhindern.Alternatively, another preferred embodiment of the invention provides a releasable connection, e.g., in place of the fixed connection to the circuit boards of the endoscopic camera, e.g. to provide in the form of a plug with connector receptacle on the camera to achieve the reliable contact of the electrical cable according to the invention via the first flexible conduit. In this case, the plug for better safety in the medical environment is preferably provided with securing elements such as barbs or fixatives that prevent unwanted loosening of the plug from the recording.

Von Vorteil ist dabei auch, dass das elektrische Kabel als Funktionseinheit hinsichtlich seiner Einzelteile und seiner Montage kostengünstig hergestellt werden kann und nach einem operativen Eingriff dementsprechend abgezogen werden und vor einer weiteren Benutzung gerade bei einer Verwendung von autoklavierbaren Kunststoffen, die das Kabel dicht kapseln, zum Beispiel vollständig in ein Desinfektionsbad eingelegt und auch anschließend platzsparend steril verpackt werden kann.It is also advantageous that the electrical cable can be produced as a functional unit with respect to its parts and its assembly cost and accordingly deducted after surgery and before further use, especially with a use of autoclavable plastics, which encapsulate the cable tightly to Example completely inserted in a disinfecting bath and then can be packed sterile to save space.

Im Folgenden wird die Erfindung anhand einer beispielhaften bevorzugten Ausführungsform näher erläutert.The invention will be explained in more detail below with reference to an exemplary preferred embodiment.

They show schematically:

an internal structure of in FIG. 1 shown in cross-section (along the line AA according to FIG Fig. 1 ).

In Fig. 1 ist ein erfindungsgemäßes elektrisches Kabel 1 schematisch im Längsschnitt gezeigt. Es umfasst eine erste 2 und eine weitere flexible Leitung 3, wobei die erste flexible Leitung 2 zwei Stecker 4 und 5 aufweist. Der Stecker 4 dient zur Verbindung mit einem Endoskopie- und Dokumentationssystem, beispielsweise mit dem TELE PACK X System von Karl Storz, und der Stecker 5 dient zur Verbindung mit einer endoskopischen Kamera, beispielsweise mit einer endoskopischen IMAGE 1 Digitalkamera von Karl Storz.In Fig. 1 an inventive electrical cable 1 is shown schematically in longitudinal section. It comprises a first 2 and a further flexible line 3, wherein the first flexible line 2 has two plugs 4 and 5. The plug 4 is used for connection to an endoscopy and documentation system, for example with the TELE PACK X system by Karl Storz, and the plug 5 is used for connection to an endoscopic camera, for example with an endoscopic IMAGE 1 digital camera by Karl Storz.

Das dargestellte elektrische Kabel 1 weist eine weitere flexible Leitung 3 mit einem Stecker 6 auf, der zusätzlich mit dem mit einem Endoskopie- und Dokumentationssystem verbunden wird. Die aus dem Stecker 6 herausführende, weitere flexible Leitung 3 mündet in den Stecker 4 der ersten flexiblen Leitung 2 und ist mit diesem elektrisch verbunden.The illustrated electrical cable 1 has a further flexible line 3 with a plug 6, which is additionally connected to the endoscopy and documentation system. The leading out of the plug 6, further flexible line 3 opens into the plug 4 of the first flexible line 2 and is electrically connected thereto.

Wie in Fig. 1 veranschaulicht zeigt der Stecker 4 Kontakte 7a, 8a, 9a und 10a, die mit Kontakten 7b, 8b, 9b und 10b im Stecker 5 über jeweils einen Leiter elektrisch leitend verbunden sind. Die Kontakte 7a und 10a bzw. 7b und 10b werden zur Energieversorgung verwandt, während die Kontakte 8a und 9a und die Kontakte 9b und 10b für die Datenübertragung verwandt werden. Damit überträgt die erste flexible Leitung 2 des erfindungsgemäßen Kabels im aufgesteckten Zustand elektrische Energie und Daten zur Datenübertragung zwischen den Steckern 4 und 5 und damit von dem Endoskopie- und Dokumentationssystem zu der endoskopischen Kamera bzw. umgekehrt.As in Fig. 1 illustrated shows the connector 4 contacts 7a, 8a, 9a and 10a, which are electrically connected to contacts 7b, 8b, 9b and 10b in the connector 5 via a respective conductor. The contacts 7a and 10a, and 7b and 10b are used for power supply, while the contacts 8a and 9a and the contacts 9b and 10b are used for data transmission. Thus, the first flexible cable 2 of the cable according to the invention in the plugged state transmits electrical energy and data for data transmission between the plugs 4 and 5 and thus from the endoscopy and documentation system to the endoscopic camera or vice versa.

Der Stecker 6 am der weiteren flexiblen Leitung 3 zeigt Kontakte 11a, 12a, 13a und 14a. Jeder Kontakt 11a, 12a, 13a und 14a ist jeweils mit einem Leiter in der weiteren flexiblen Leitung 3 elektrisch leitend verbunden, wobei die Kontakte 11a und 14a zur Energieversorgung und die Kontakte 12a und 13a zur Datenübertragung dienen.The plug 6 on the further flexible line 3 shows contacts 11a, 12a, 13a and 14a. Each contact 11a, 12a, 13a and 14a is electrically connected to a conductor in the other flexible line 3, wherein the contacts 11a and 14a for power supply and the contacts 12a and 13a are used for data transmission.

Wie in Figur 1 gezeigt, verlaufen 2 Daten- und 2 Energieübertragungsleiter vom Stecker 6 in der weiteren flexiblen Leitung 3 und münden schließlich in den Stecker 4 der ersten flexiblen Leitung 2 des elektrischen Kabels 1. Im Stecker 4 ist jeder dieser Leiter dann mit einer der Lötflächen 11', 12', 13' und 14' mechanisch und elektrisch leitend verbunden. Jeder diese Leiter ist dann selektiv über die jeweils zugeordnete Lötflächen 11', 12', 13' und 14' mit Leitern in der ersten flexiblen Leitung 2 selektiv mit den zugeordneten Kontakten 11b, 12b, 13b und 14b des Steckers 5 elektrisch leitend verbunden. Somit können sowohl Energie als auch Daten zwischen dem Stecker 5 und Stecker 6 zugleich über die Lötflächen 11', 12', 13' und 14' im Stecker 4 "durchgeschliffen" werden", sodass über die weitere flexible Leitung 3 eine weitere, direkte Energie- und Datenverbindung zwischen dem Endoskopie- und Dokumentationssystem und der endoskopischen Kamera hergestellt ist.As in FIG. 1 2 data and 2 energy transmission conductors extend from the plug 6 in the further flexible line 3 and finally terminate in the plug 4 of the first flexible line 2 of the electric cable 1. In the plug 4, each of these conductors is then connected to one of the soldering surfaces 11 ', 12 ', 13' and 14 'mechanically and electrically conductively connected. Each of these conductors is then selectively electrically connected to the associated contacts 11b, 12b, 13b and 14b of the plug 5 selectively via the respectively associated pads 11 ', 12', 13 'and 14' with conductors in the first flexible line 2. Thus, both energy and data between the plug 5 and connector 6 at the same time through the pads 11 ', 12', 13 'and 14' in the plug 4 "are through-ground", so on the other flexible line 3, a further, direct energy - And data connection between the endoscopy and documentation system and the endoscopic camera is made.

Die Stecker 4 und 6 sind dabei entsprechend dem USB-Standard ausgebildet, so dass mit zwei USB-Anschlüssen an dem mobilen Endoskopie- und Dokumentationssystems auf einfache und sicherere Weise zusammenwirken können. Dieses erfindungsgemäße elektrische Kabel ermöglicht im verbundenen Zustand gegenüber einem standardmäßigen USB-Kabel den erhöhten Energieversorgungs- und Datenübertragungsbedarf zwischen den angeschlossenen Geräten zu befriedigen. Zudem erweist es sich in seiner Handhabung als sehr sicher und was gerade bei einer Anwendung in einem Operationssaal oder in einer medizinischen Notfallsituation wichtig ist, da es sich als sehr risikoarm zeigt, da Fehlhandhabungen oder ein Stolpern über das Kabel durch den erfindungsgemäßen Aufbau reduziert sind.The plug 4 and 6 are designed according to the USB standard, so that can interact with two USB ports on the mobile endoscopy and documentation system in a simple and safer way. This electrical cable according to the invention allows in the connected state compared to a standard USB cable to meet the increased power supply and data transmission needs between the connected devices. In addition, it proves to be very safe in its handling and what is important in particular in an application in an operating room or in a medical emergency situation, since it is shown to be very low risk, since incorrect handling or tripping over the cable is reduced by the construction according to the invention.

Der innere Aufbau der in Figur 1 schematisch dargestellten ersten flexiblen Leitung 2 ist Figur 2 entnehmbar. Die erste flexible Leitung 2 enthält eine Vielzahl von einzelnen Leitern, die in Gruppen angeordnet sind. Die Leiter für die Energieübertragung tragen die Bezugszahlen 16a, 16b, 16c und 16d und sind verteilt an mehreren Stellen innerhalb der ersten flexiblen Leitung 2 angeordnet. Paarweise jeweils zu einer Gruppe zusammengefasst sind ferner die Leiter für die Datenübertragung 17a, 17b, 17c und 17d, wobei jeweils zwei zu einem Paar angeordnete Datenleiter von einer Folie 18a und 18b zur Abschirmung umgeben sind, die beispielsweise aus einer Aluminium kaschierten Kunststofffolie gefertigt sein kann. Schließlich ist die gesamte Anordnung von einer metallenen Abschirmung 19 umgeben, welche vorzugsweise aus verzinktem Kupferdraht gefertigt ist, welche wiederum von einem elektrisch isolierenden Mantel 20 ummantelt ist. Hierdurch ist eine gute Übertragung Datenübertragung ohne starke negative EMV-Einflüsse geschaffen.The internal structure of in FIG. 1 schematically illustrated first flexible conduit 2 is FIG. 2 removable. The first flexible conduit 2 includes a plurality of individual conductors arranged in groups. The conductors for the transmission of energy carry the reference numerals 16a, 16b, 16c and 16d and are arranged distributed at several locations within the first flexible conduit 2. In pairs, each grouped into a group, the data transmission conductors 17a, 17b, 17c and 17d are also provided, with two data conductors each arranged to form a pair of films 18a and 18b for shielding are surrounded, which can be made for example of an aluminum-laminated plastic film. Finally, the entire assembly is surrounded by a metal shield 19, which is preferably made of galvanized copper wire, which in turn is covered by an electrically insulating jacket 20. This creates a good transmission of data transmission without strong negative EMC influences.

Wie in Fig. 1 und Fig. 2 veranschaulicht, wird im eingesteckten Zustand des erfindungsgemäßen Y-förmigen elektrischen Kabels 1 mit den beiden flexiblen Leitung 2 und 3 zusätzliche Daten- und Stromversorgungsleiter bereitgestellt, die es ermöglicht, gegenüber einem Standard USB Kabel einen erhöhten Datenaustausch zu ermöglichen und gleichzeitig einen erhöhten Stromversorgungsbedarf für ein angeschlossenes Peripheriegerät zu befriedigen.As in Fig. 1 and Fig. 2 illustrated, in the inserted state of the Y-shaped electric cable 1 according to the invention with the two flexible line 2 and 3 additional data and power supply conductor is provided, which allows, compared to a standard USB cable to allow increased data exchange and simultaneously increased power supply requirements for a connected peripheral device to satisfy.
