Beschreibungdescription
Die Erfindung betrifft ein elektrochirurgisches Instrument, umfassend mindestens eine Anzeigevorrichtung zur Anzeige mindestens einer Statusinformation einer Steuereinheit sowie einen Adapter zum Anschluss eines elektrochirurgischen Instruments.The invention relates to an electrosurgical instrument comprising at least one display device for displaying at least one status information of a control unit and an adapter for connecting an electrosurgical instrument.
Elektrochirurgische Instrumente werden seit vielen Jahren in der Hochfrequenzchirurgie (HF-Chirurgie) eingesetzt, um biologisches Gewebe zu koagulieren oder auch zu schneiden. Bei einer Koagulation wird ein hochfrequenter Strom durch das zu behandelnde Gewebe geleitet, so dass sich dieses aufgrund von Eiweißgerinnung und Dehydratation verändert. Das Gewebe zieht sich dabei derart zusammen, dass die Gefäße verschlossen und Blutungen gestillt werden. Nach erfolgreicher Koagulation ist das Gewebe unter Vermeidung starker Blutungen vollständig durchtrennbar, sowohl mit Hilfe von hochfrequentem Strom, als auch auf mechanischem Wege. .Electrosurgical instruments have been used for many years in high frequency surgery (RF surgery) to coagulate or even cut biological tissue. In coagulation, a high-frequency current is passed through the tissue to be treated, so that this changes due to protein coagulation and dehydration. The tissue contracts in such a way that the vessels are closed and bleeding is stopped. After successful coagulation, the tissue is completely severable while avoiding heavy bleeding, both with the help of high-frequency current, as well as by mechanical means. ,
Elektrochirurgische Vorgänge sind mit monopolaren und bipolaren Instrumenten durchführbar. Bei der monopolaren Technik führt der Strompfad üblicherweise vom elektrochirurgischen Instrument über das zu behandelnde Gewebe zu einer Neutralelektrode. Alternativ können bipolare Instrumente verwendet werden, die mit zwei voneinander elektrisch isolierten Abschnitten ausgebildet sind. Der Stromweg verläuft in diesem Fall von einem ersten Abschnitt des elektrochirurgischen Instruments über das zu behandelnde Gewebe zu einem zweiten Abschnitt des elektrochirurgischen Instruments.Electrosurgical procedures can be performed with monopolar and bipolar instruments. In the monopolar technique, the current path usually leads from the electrosurgical instrument via the tissue to be treated to a neutral electrode. Alternatively, bipolar instruments may be used, which are formed with two mutually electrically isolated sections. The current path in this case extends from a first section of the electrosurgical instrument via the tissue to be treated to a second section of the electrosurgical instrument.
Für die erfolgreiche Durchführung einer Operation mittels eines elektrochirurgischen Instruments ist eine hohe Bedienerfreundlichkeit wichtig. Das elektrochirurgische Instrument sollte sich intuitiv bedienen lassen und sämtliche nötigen Informationen sollten einfach abrufbar sein. Diese Informationen umfassen insbesondere Statusinformationen, die beispielsweise von einem HF-Generator bereitgestellt werden.For the successful execution of an operation by means of an electrosurgical instrument, a high degree of user-friendliness is important. The electrosurgical instrument should be intuitive to use and should contain all the necessary information be easily available. In particular, this information includes status information provided, for example, by an RF generator.
Besonders problematisch ist die Tatsache, dass häufig mehrere elektrochirurgische Instrumente an einem HF-Generator angeschlossen sind. In diesen Fällen muss eine Auswahl getroffen werden, welches der Instrumente mit einer HF-Spannung versorgt werden soll. Eine Zuordnung der Ausgänge des HF-Generators zu einem konkreten Instrument, sei es eine bipolare Klammer oder eine monopolare Hakenelektrode, ist hierbei häufig schwierig.Particularly problematic is the fact that often several electrosurgical instruments are connected to an RF generator. In these cases, a choice must be made as to which of the instruments should be supplied with an RF voltage. An assignment of the outputs of the RF generator to a specific instrument, be it a bipolar clamp or a monopolar hook electrode, is often difficult.
Aus dem Stand der Technik sind diverse elektrochirurgische Instrumente bekannt.Various electrosurgical instruments are known from the prior art.
Die DE 36 27 221 Al zeigt beispielsweise einen Handgriff für ein elektrochirurgisches Instrument, das eine Leistungssteuerung sowie eine optische Leistungsanzeige aufweist. Diese Leistungsanzeige auf dem Handgriff gibt Informationen über die abgegebene Leistung, beispielsweise das Anliegen einer hohen oder niedrigen Spannung, an.DE 36 27 221 Al, for example, shows a handle for an electrosurgical instrument having a power control and an optical power indicator. This power indicator on the handle indicates information about the power delivered, such as the presence of high or low voltage.
Aus der DE 40 12 545 Al ist ein Handgriff für ein elektrochirurgisches Instrument bekannt, das sich dadurch auszeichnet, dass am elektrodenseitigen Ende des Handgriffs eine Lichtaustrittsöffnung vorgesehen ist, die von einem im HF-Generator befindlichen Kaltlichtgenerator gespeist wird. Die Lichtquelle dient dazu, das Operationsfeld besser auszuleuchten.From DE 40 12 545 Al a handle for an electrosurgical instrument is known, which is characterized in that the electrode-side end of the handle, a light exit opening is provided, which is fed by a located in the RF generator cold light generator. The light source serves to illuminate the surgical field better.
Die DE 199 43 792 Al offenbart ein elektrochirurgisches Instrument, bei dem der daran angeordnete Handgriff eine Anzeigevorrichtung aufweist, die es ermöglicht, betriebsspezifische Informationen, beispielsweise Betriebsmodus des elektrochirurgischen Instruments abzulesen.DE 199 43 792 A1 discloses an electrosurgical instrument in which the handle arranged thereon has a display device which makes it possible to read operation-specific information, for example the operating mode of the electrosurgical instrument.
Die vorab beschriebenen Instrumente sind sehr aufwendig aufgebaut.The instruments described above are very complex.
Ausgehend von diesem Stand der Technik ist es Aufgabe der vorliegenden Erfindung, ein leicht und komfortabel bedienbares elektrochirurgisches Instrument bereit zu stellen. Diese Aufgabe wird erfindungsgemäß durch ein elektrochirurgisches Instrument nach Anspruch 1 gelöst.Based on this prior art, it is an object of the present invention to provide an easy and comfortable to use electrosurgical instrument. This object is achieved by an electrosurgical instrument according to claim 1.
Insbesondere wird die Aufgabe durch ein elektrochirurgisches Instrument, umfassend mindestens eine Anzeigevorrichtung zur Anzeige mindestens einer Statusinformation einer Steuereinheit, gelöst, wobei die Anzeigevorrichtung derart an dem elektrochirurgi- schen Instrument angeordnet und in dessen Distalrichtung ausgerichtet ist, dass die Anzeigevorrichtung in einem Aktivzustand ein Operationsfeld des elektrochirurgischen Instruments ausleuchtet.In particular, the object is achieved by an electrosurgical instrument, comprising at least one display device for displaying at least one status information of a control unit, wherein the display device is arranged on the electrosurgical instrument and oriented in the distal direction, that the display device in an active state, an operating field of electrosurgical instrument illuminates.
Die Anzeigevorrichtung kann eine einzelne Leuchtdiode oder ein Array oder eine Matrix von Leuchtdioden sein. Vorzugsweise handelt es sich hierbei um aktive Elemente, die mindestens einen Status einer Steuereinheit und/oder des HF-Generators und/oder des elektrochirurgischen Instruments selbst angeben. In einem Ausführungsbeispiel kann ein Aktivzustand der Anzeigevorrichtung als der Zustand definiert sein, in dem die Anzeigevorrichtung erleuchtet ist. Vorzugsweise korreliert der Aktivzustand der Anzeigevorrichtung mit einem Aktivzustand des elektrochirurgischem Instruments, in dem dieses unmittelbar betriebsbereit ist, beispielsweise ein Strom zur Durchführung eines Koagulationsvorgangs anliegt.The display device may be a single light emitting diode or an array or matrix of light emitting diodes. These are preferably active elements which indicate at least one status of a control unit and / or of the HF generator and / or of the electrosurgical instrument itself. In one embodiment, an active state of the display device may be defined as the state in which the display device is illuminated. The active state of the display device preferably correlates with an active state of the electrosurgical instrument in which it is immediately ready for operation, for example a current is present for carrying out a coagulation process.
Der Vorteil der vorliegenden Erfindung besteht also darin, dass die Anzeige nicht nur dazu verwendet wird, dem Anwender des Geräts bzw. des elektrochirurgischen Instruments Informationen über dessen Status zu vermitteln, sondern gleichzeitig eine Beleuchtungsfunktion erfüllt, die bei dem eigentlichen Eingriff, der mittels des elektrochirurgischen Instruments durchgeführt wird, hilfreich ist.The advantage of the present invention is therefore that the display is not only used to provide the user of the device or the electrosurgical instrument information about its status, but at the same time fulfills a lighting function, which in the actual intervention by means of the electrosurgical Instrument is helpful.
In einem Ausführungsbeispiel umfasst das elektrochirurgische Instrument einen Handgriff, wobei die mindestens eine Anzeigevorrichtung an einem Distalende des Handgriffs angeordnet ist. Das heißt, die Anzeigevorrichtung ist derart angeordnet, dass sie in Richtung des eigentlichen Werkzeugkopfs des elektrochirurgischen Instruments strahlt und somit den Bereich, an dem das elektrochirurgische Instrument eingesetzt werden soll, ausleuchtet. Das beschriebene elektrochirurgische Instrument hat bei einem handgeführten Instrument besondere Vorteile. In einem weiteren Ausführungsbeispiel ist die Anzeigevorrichtung zur Abgabe von farbigem Licht ausgebildet. Die unterschiedlichen Farbtöne können entweder dazu benutzt werden, unterschiedliche Statusinformationen anzuzeigen, oder dazu, unterschiedliche elektrochirurgische Instrumente zu kennzeichnen. Beispielsweise könnte der Farbton der Anzeigevorrichtung des elektrochirurgischen Instruments mit einem Farbton am HF-Generator korrespondieren, um anzuzeigen, dass unter einer Vielzahl von elektrochirurgischen Instrumenten das vorliegende aktiv ist bzw. dass am vorliegenden elektrochirurgischen Instrument eine HF-Spannung anliegt.In one embodiment, the electrosurgical instrument includes a handle, wherein the at least one display device is disposed at a distal end of the handle. That is, the display device is arranged so that it radiates in the direction of the actual tool head of the electrosurgical instrument and thus illuminates the area where the electrosurgical instrument is to be used. The electrosurgical instrument described has particular advantages in a hand-held instrument. In a further embodiment, the display device is designed to emit colored light. The different hues can either be used to indicate different status information or to identify different electrosurgical instruments. For example, the hue of the display device of the electrosurgical instrument could correspond to a hue on the RF generator to indicate that, among a variety of electrosurgical instruments, the present one is active, or that an RF voltage is applied to the present electrosurgical instrument.
In einem weiteren Ausführungsbeispiel zeigt die mindestens eine Statusinformation ein Anliegen einer Spannung am elektrochirurgischen Instrument und/oder eine Leistungsangabe und/oder einen Operationsmodus der Steuereinheit an. Wie bereits erwähnt, ist es sinnvoll, das Anliegen einer Spannung anzugeben, wenn zwischen einer Vielzahl von Instrumenten, die teilweise oder allesamt am selben HF-Generator angeschlossen sind, unterschieden werden muss. Auch wenn nur ein einziges elektrochirurgisches Instrument verwendet wird, kann es sinnvoll sein, den aktiven Zustand des elektrochirurgischen Instruments besonders zu kennzeichnen, um eine fehlerhafte Bedienung zu vermeiden. Die Farbangabe kann eine Stromstärke und/oder eine Spannung und/oder eine Frequenz und/oder ein besonderes Frequenzmuster visualisieren. Beispielsweise wurde festgestellt, dass für die Koagulation von Gewebe ein anderes Spannungsmuster nötig ist (erster Operationsmodus), als das Spannungsmuster, das zum Durchtrennen eines entsprechenden Gewebes Anwendung findet (zweiter Operationsmodus). Die farbliche Kennzeichnung könnte also dazu dienen, die Operationsmodi zu unterscheiden.In a further embodiment, the at least one status information indicates a concern of a voltage on the electrosurgical instrument and / or a power indication and / or an operation mode of the control unit. As already mentioned, it makes sense to indicate the presence of a voltage when a distinction has to be made between a plurality of instruments which are partly or all connected to the same HF generator. Even if only a single electrosurgical instrument is used, it may be useful to particularly mark the active state of the electrosurgical instrument to avoid erroneous operation. The color indication can visualize a current intensity and / or a voltage and / or a frequency and / or a particular frequency pattern. For example, it has been found that coagulation of tissue requires a different voltage pattern (first mode of operation) than the voltage pattern used to cut through a corresponding tissue (second mode of operation). The color coding could therefore serve to distinguish the modes of operation.
In einem weiteren Ausführungsbeispiel ist die Anzeigevorrichtung in eine Versorgungsspannung des elektrochirurgischen Instruments eingekoppelt. Die Anzeigevorrichtung kann somit teilweise oder vollumfänglich durch die Versorgungsspannung, die beispielsweise für einen Koagulationsprozess am elektrochirurgischen Instrument anliegt, gespeist werden.In a further embodiment, the display device is coupled into a supply voltage of the electrosurgical instrument. The display device can thus be partially or fully fed by the supply voltage, which is present for example for a coagulation process on the electrosurgical instrument.
Die besagte Aufgabe wird des Weiteren durch einen Adapter gemäß dem vorliegenden Anspruch 6 gelöst. Insbesondere wird die Aufgabe durch einen Adapter zum Anschluss eines elektrochirurgi- schen Instruments gelöst, wobei der Adapter umfasst:The said object is further solved by an adapter according to the present claim 6. In particular, the object is achieved by an adapter for connecting an electrosurgical instrument, wherein the adapter comprises:
mindestens eine Versorgungsleitung zur Bereitstellung einer Versorgungsspannung für das elektrochirurgische Instrument; und eine Anzeigevorrichtung, die an die mindestens eine Versorgungsleitung angeschlossen ist.at least one supply line for providing a supply voltage for the electrosurgical instrument; and a display device connected to the at least one supply line.
Eine vorteilhafte Unterscheidung unterschiedlicher elektrochirurgischer Instrumente kann sich also dadurch ergeben, dass der Adapter, an den das entsprechende elektrochirurgische Instrument angeschlossen wird, eine Anzeigevorrichtung umfasst, die das entsprechende Instrument bzw. den Adapter kennzeichnet. Die Anzeigevorrichtung am Adapter kann ebenfalls dazu dienen, Statusinformationen für den Benutzer des elektro- chirurgischen Instruments bereit zu stellen. Der Adapter kann beispielsweise das Ende eines Versorgungskabels des elektrochirurgischen Instruments sein, wobei der Adapter vorzugsweise eine Vielzahl von Anschlüssen zum Anschluss des Instruments umfasst. In einem Ausführungsbeispiel kann der Adapter Bedienelemente umfassen.An advantageous distinction between different electrosurgical instruments can thus result from the fact that the adapter to which the corresponding electrosurgical instrument is connected comprises a display device which identifies the corresponding instrument or adapter. The indicator on the adapter may also serve to provide status information to the user of the electrosurgical instrument. The adapter may be, for example, the end of a supply cable of the electrosurgical instrument, the adapter preferably comprising a plurality of terminals for connecting the instrument. In one embodiment, the adapter may include controls.
In einem weiteren Ausführungsbeispiel ist die mindestens eine Versorgungsleitung zur Bereitstellung einer HF-Spannung ausgebildet. Das heißt, der Adapter stellt die Versorgungsspannung für das elektrochirurgische Instrument bereit und ist vorzugsweise mit dem HF-Generator elektrisch verbunden.In a further embodiment, the at least one supply line is designed to provide an HF voltage. That is, the adapter provides the supply voltage for the electrosurgical instrument and is preferably electrically connected to the RF generator.
In einem weiteren Ausführungsbeispiel ist die Anzeigevorrichtung zur Abgabe von farbigem Licht ausgebildet. Die Anzeigevorrichtung kann entweder so ausgebildet sein, dass sie eine Vielzahl von unterschiedlichen Farbtönen, beispielsweise Rot, Grün, Blau emittieren kann. Die einzelnen Farbtöne können dazu dienen, unterschiedliche Statusinformationen zu transportieren. Alternativ können mehrere Adapter vorgesehen sein, bei denen jeweils ein Adapter dazu geeignet ist, einen bestimmten Farbton abzugeben. Eine Unterscheidung von mehreren Adaptern und somit von daran angeschlossenen elektrochirurgischen Instrumenten kann in diesem Fall anhand des Farbtons vorgenommen werden. Vorzugsweise handelt es sich bei der Anzeigevorrichtung um ein aktives Lichtelement, das selbstständig Licht emittiert. Alternativ kann die Anzeigevorrichtung mittels eines Lichtwellenleiters bereitgestellt werden, die erzeugte Lichtwellen an den Adapter transportiert. Beispielsweise kann der Lichtwellengenerator innerhalb des HF-Generators vorgesehen sein. Beim Anschluss des Adapters an den HF-Generator erfolgt eine automatische Einkopplung der dem Anschluss zugeordneten Lichtquelle.In a further embodiment, the display device is designed to emit colored light. The display device can either be designed so that it can emit a multiplicity of different hues, for example red, green, blue. The individual shades can be used to convey different status information. Alternatively, a plurality of adapters may be provided, in each of which an adapter is adapted to deliver a particular color. A distinction from several adapters and thus connected electrosurgical instruments can be made in this case on the basis of the hue. Preferably, the display device is an active light element that emits light on its own. Alternatively, the display device may be provided by means of an optical waveguide which transports generated light waves to the adapter. For example, the light wave generator can be provided within the RF generator. When the adapter is connected to the HF generator, an automatic coupling of the light source assigned to the connection takes place.
In einem weiteren Ausführungsbeispiel ist die Anzeigevorrichtung zum Anzeigen einer anliegenden Spannung, insbesondere einer HF-Spannung, ausgebildet. Die durch die Anzeigevorrichtung angezeigte Statusinformation kann also angeben, ob das angeschlossene elektrochirurgische Instrument oder der Adapter aktiv ist, d.h. mit einer entsprechenden Spannung versorgt wird.In a further exemplary embodiment, the display device is designed to display an applied voltage, in particular an HF voltage. Thus, the status information displayed by the display device may indicate whether the connected electrosurgical instrument or adapter is active, i. is supplied with a corresponding voltage.

FIG. In the following description, the same reference numerals are used for the same and like parts.
Fig. 1 zeigt ein elektrochirurgisches Instrument 10, das sich aus einem Handgriff 12 und einem bipolaren Instrumentenkopf 14 zusammensetzt. Der Handgriff 12 hat eine längliche Form, wobei an dessen distalen Ende der bipolare Instrumentenkopf 14 zur Durchführung eines operativen Eingriffs ansetzt. Der Instrumentenkopf 14 weist eine erste Elektrode 16 und einer zweiten Elektrode 16' auf, an denen eine Spannung zur Koagulation oder zum Schneiden vom Gewebe anliegt. Das elektrochirurgische Instrument 10 weist des Weiteren am distalen Ende des Handgriffs 12 eine Anzeigevorrichtung 50 auf, die derart ausgebildet ist, dass sie den bipolaren Instrumentenkopf 14 sowie ein distales Operationsfeld beleuchtet. Des Weiteren ist die Anzeigevorrichtung 50 dazu ausgebildet, mindestens eine Statusinformation anzuzeigen. Im vorliegenden Fall zeigt die Anzeigevorrichtung 50 an, ob an den Elektroden 16, 16' eine Spannung anliegt.Fig. 1 shows an electrosurgical instrument 10, which is composed of a handle 12 and a bipolar instrument head 14. The handle 12 has an elongated shape, at the distal end of which the bipolar instrument head 14 attaches to perform a surgical procedure. The instrument head 14 has a first electrode 16 and a second electrode 16 'against which a voltage for coagulation or for cutting tissue is applied. The electrosurgical instrument 10 further includes a display device 50 at the distal end of the handle 12 that is configured to illuminate the bipolar instrument head 14 and a distal surgical field. Furthermore, the display device 50 is configured to display at least one status information. In the present case, the display device 50 indicates whether a voltage is applied to the electrodes 16, 16 '.
Das erfindungsgemäße elektrochirurgische System lässt sich grob in die folgenden vier Komponenten gliedern (vgl. hierzu Fig. 2):The electrosurgical system according to the invention can be roughly divided into the following four components (see FIG.
elektrochirurgisches Instrument 10electrosurgical instrument 10
- HF-Generator 20RF generator 20
- Fußschalter 30 Steuereinheit 40Foot switch 30 control unit 40
Um das elektrochirurgische Instrument 10 mit einer für die jeweilige Operation geeigneten Spannung und/oder geeignetem Frequenzmuster zu versorgen, verfügt das System über die Steuereinheit 40, die derart auf den HF-Generator 20 einwirkt, dass dieser eine entsprechende Ausgabe bereitstellt. Um auf das Verhalten der Steuereinheit 40 einwirken zu können, verfügt das System über eine Eingabevorrichtung, insbesondere über einen Fußschalter 30. Mittels des Fußschalters 30 kann beispielsweise an einem bestimmten Instrument 10 ein bestimmter Operationsmodus eingestellt werden. Der Fußschalter 30 kann auch dazu dienen aus einer Vielzahl von an den HF-Generator 20 angeschlossenen Instrumenten 10 eines auszuwählen, dass dann mit einem entsprechenden HF-Spannung versorgt wird. Die Anzeigevorrichtung 50 dient dazu, Informationen über die Steuereinheit 40, den HF- Generator 20 oder das elektrochirurgische Instrument 10 bereit zu stellen. Insbesondere kann die Anzeigevorrichtung 50 erfindungsgemäß einen Aktivierungszustand des elektro- chirurgischen Instruments 10 anzeigen. Hierfür ist, wie in Fig. 3 gezeigt, die Anzeigevorrichtung 50 in die elektrische Verbindung zwischen HF-Generator 20 und elektrochirur- gischem Instrument 10 eingekoppelt. Die Fig. 3 zeigt eine erste Aus führungs form, bei der die Anzeigevorrichtung 50 an einem bipolaren elektrochirurgischen Instrument 10 angeordnet ist. In einer derartigen Konstellation existieren üblicherweise zwei unmittelbare, elektrische Leitungen zwischen dem HF-Generator 20 und dem elektrochirurgischen Instrument 10. In der in Fig. 3 gezeigten Ausführungsform sind dies die HF-Leitungen 41 , 41'.To provide the electrosurgical instrument 10 with a voltage and / or frequency pattern suitable for the particular operation, the system includes the control unit 40 which acts on the RF generator 20 to provide a corresponding output. In order to be able to act on the behavior of the control unit 40, the system has an input device, in particular a foot switch 30. By means of the foot switch 30, for example, a specific operation mode can be set on a specific instrument 10. The footswitch 30 can also be used to select from a plurality of instruments 10 connected to the RF generator 20 that are then supplied with a corresponding RF voltage. The display device 50 serves to provide information about the control unit 40, the RF generator 20 or the electrosurgical instrument 10. In particular, the display device 50 can according to the invention indicate an activation state of the electrosurgical instrument 10. For this purpose, as shown in FIG. 3, the display device 50 is coupled into the electrical connection between the HF generator 20 and the electro-surgical instrument 10. FIG. 3 shows a first embodiment in which the display device 50 is arranged on a bipolar electrosurgical instrument 10. In such a constellation, there are usually two direct electrical lines between the RF generator 20 and the electrosurgical instrument 10. In the embodiment shown in FIG. 3, these are the RF lines 41, 41 '.
Wie in Fig. 4 gezeigt, kann sich die Anzeigevorrichtung 50 aus einer ersten Leuchtdiode 54 und einer zweiten Leuchtdiode 54' zusammensetzen, wobei die Leuchtdioden 54, 54' jeweils parallel zu den Elektroden 16, 16' des bipolaren Instrumentenkopfs 14 an der ersten HF-Leitung 41 und der zweiten HF-Leitung 41' angeordnet sind. Die Versorgungsleitungen des elektrochirurgischen Instruments 10 versorgen die Anzeigevorrichtung 50 mit Strom. Um einen Betrieb der Anzeigevorrichtung 50 auch bei der üblichen Wechselspannung zu gewährleisten, sind den Leuchtdioden 54, 54' jeweils Schutzdioden 53, 53' vorgeschaltet. Entsprechend angeordnete Widerstände 52, 52' regeln die Spannung, die der Anzeigevorrichtung 50, umfassend die beiden Leuchtdioden 54, 54', zugeführt wird. Für einen ersten und einen zweiten Leuchtdiodenstrang ergibt sich also eine Serienschaltung, umfassend einen Widerstand 52 bzw. 52', eine Leuchtdiode 54 bzw. 54' und eine Schutzdiode 53 bzw. 53'. Die Schutzdioden 53, 53' sind derart angeordnet und ausgebildet, dass in dem ersten Leuchtdiodenstrang ein elektrischer Strom in eine erste Flussrichtung und in dem zweiten ein elektrischer Strom in eine zweite, der ersten entgegengesetzten Flussrichtung zugelassen wird.As shown in FIG. 4, the display device 50 may be composed of a first light-emitting diode 54 and a second light-emitting diode 54 ', wherein the light-emitting diodes 54, 54' are respectively connected in parallel to the electrodes 16, 16 'of the bipolar instrument head 14 on the first RF Line 41 and the second RF line 41 'are arranged. The supply lines of the electrosurgical instrument 10 supply power to the display device 50. In order to ensure operation of the display device 50 even with the usual AC voltage, the light-emitting diodes 54, 54 'each protective diodes 53, 53' upstream. Correspondingly arranged resistors 52, 52 'regulate the voltage supplied to the display device 50 comprising the two light-emitting diodes 54, 54'. For a first and a second light-emitting diode string thus results in a series circuit comprising a resistor 52 or 52 ', a light emitting diode 54 or 54' and a protective diode 53 or 53 '. The protective diodes 53, 53 'are arranged and designed such that in the first light-emitting diode string an electric current in a first flow direction and in the second an electric current in a second, the first opposite flow direction is allowed.
Eine weitere Aus führungs form der Anzeigevorrichtung 50 ist in Fig. 5 dargestellt. Hier ist eine Glühlampe 56 mit einem entsprechenden Widerstand 52" in die erste und zweite HF-Leitung 41, 41' eingekoppelt. Eine Gleichrichtung des Versorgungsstromes ist hierbei nicht nötig. Fig. 6 zeigt eine induktive Einkopplung der Anzeigevorrichtung 50 in den Versorgungsstromkreis des bipolaren Instrumentenkopfs 14. Hierfür enthält die erste HF-Leitung eine erste Induktionsspule 57, die magnetisch an eine zweite Induktionsspule 57' gekoppelt ist. Die induzierte Energie an der zweiten Induktionsspule 57' wird zum Betreiben einer weiteren Leuchtdiode 54" verwendet, der ein Widerstand 52'" vorgeschaltet ist.Another embodiment of the display device 50 is shown in FIG. Here, an incandescent lamp 56 with a corresponding resistor 52 "is coupled into the first and second HF line 41, 41. A rectification of the supply current is not necessary here. Fig. 6 shows an inductive coupling of the display device 50 in the supply circuit of the bipolar instrument head 14. For this purpose, the first RF line includes a first induction coil 57 which is magnetically coupled to a second induction coil 57 '. The induced energy at the second induction coil 57 'is used to drive another light emitting diode 54 ", preceded by a resistor 52'".
Alternativ kann die erfindungsgemäße Anzeigevorrichtung 50 auch bei monopolaren elektrochirurgischen Instrumenten 10 eingesetzt werden. Fig. 7 zeigt eine entsprechende Anordnung. Üblicherweise wird das monopolare Instrument über eine erste HF-Leitung 41 unmittelbar mit der Spannung des HF-Generators 20 versorgt. Eine zweite HF- Leitung 41 ' kontaktiert eine Neutralelektrode 1 , die unmittelbar mit dem Patienten in Kontakt steht. Um die erfindungsgemäße Anzeigevorrichtung 50 gemäß Fig. 4 oder 5 betreiben zu können, muss eine weitere Leitung 41" vorgesehen werden, die die Anzeigevorrichtung versorgt. Auch in dieser Ausführungsform wird die Anzeigevorrichtung 50 von der Versorgungsspannung für das elektrochirurgische Instrument gespeist. Für die induktive Einkopplung der Anzeigevorrichtung 50 kann auf die HF-Leitung 41" verzichtet werden.Alternatively, the display device 50 according to the invention can also be used in monopolar electrosurgical instruments 10. Fig. 7 shows a corresponding arrangement. The monopolar instrument is usually supplied directly with the voltage of the HF generator 20 via a first HF line 41. A second RF line 41 'contacts a neutral electrode 1, which is in direct contact with the patient. In order to be able to operate the display device 50 according to the invention according to Fig. 4 or 5, a further line 41 "has to be provided which supplies the display device. <br/> <br/> Also in this embodiment, the display device 50 is fed by the supply voltage for the electrosurgical instrument the display device 50 can be dispensed with the RF line 41 ".
Die vorab beschriebene Anzeigevorrichtung 50 lässt sich erfindungsgemäß auch in einen Adapter integrieren, an den ein elektrochirurgisches Instrument 10 angeschlossen werden kann. Vorzugsweise lässt sich der Handgriff 12 des elektrochirurgischen Instruments 10 auf entsprechende Anschlüsse des Adapters aufstecken. In dieser Ausführungsform nutzt die Anzeigevorrichtung ebenfalls die Versorgungsspannung des elektrochirurgischen Instruments 10, um die zugehörigen Leuchtdioden 54, 54', 54" oder eine entsprechende Glühlampe 56 zu betreiben. Die Schaltungen gemäß den Figuren 4 — 6 lassen sich entsprechend für eine Verwendung im Adapter anpassen.The display device 50 described above can also be integrated according to the invention into an adapter to which an electrosurgical instrument 10 can be connected. Preferably, the handle 12 of the electrosurgical instrument 10 can be plugged onto corresponding terminals of the adapter. In this embodiment, the display device also utilizes the supply voltage of the electrosurgical instrument 10 to operate the associated light emitting diodes 54, 54 ', 54 "or a corresponding incandescent lamp 56. The circuits of Figures 4-6 can be suitably adapted for use in the adapter ,
In einer weiteren Ausführungsform wird die Anzeigevorrichtung 50 des Adapters über einen neben den Versorgungsleitungen für das Instrument 10 verlaufenden Lichtwellenleiter mit chromatischen Lichtwellen versorgt. Der HF-Generator 12 kann derart ange- passt sein, dass, im Fall des Anliegens einer Spannung am Adapter und somit auch am aufgesteckten elektrochirurgischen Instrument 10, die Anzeigevorrichtung 50 mit entsprechend eingefärbtem Licht versorgt wird. Alternativ kann der HF-Generator 20 und die Steuereinheit derart ausgebildet sein, dass Lichtwellen für einen bestimmten Adapter unter einer Vielzahl von an den HF-Generator 20 angeschlossenen Adaptern nur dann bereitgestellt wird, wenn an der entsprechenden Versorgungsspannung Strom anliegt. Des Weiteren kann eine fest vorgegebene Lichtfarbe der Anzeigevorrichtung 50 mit einer Lichtfarbe an dem HF-Generator 20 korrespondieren, um anzuzeigen, dass genau an diesem Adapter Spannung anliegt.In a further embodiment, the display device 50 of the adapter is supplied with chromatic light waves via an optical waveguide extending alongside the supply lines for the instrument 10. The HF generator 12 may be adapted such that, in the case of the application of a voltage to the adapter and thus also to the attached electrosurgical instrument 10, the display device 50 is supplied with correspondingly colored light. Alternatively, the RF generator 20 and the control unit be configured such that light waves for a specific adapter are only provided among a plurality of adapters connected to the HF generator 20 if current is present at the corresponding supply voltage. Furthermore, a predefined light color of the display device 50 may correspond to a light color on the HF generator 20 in order to indicate that voltage is applied precisely to this adapter.
In einer weiteren Ausführungsform können die Leuchtdioden 54, 54', 54" derart ange- passt sein, dass diese ein farbiges Licht abgeben, dass beispielsweise mit einer Anzeigenfarbe einer Anzeige am HF-Generator 20 korrespondiert.In a further embodiment, the light-emitting diodes 54, 54 ', 54 "may be adapted such that they emit a colored light that, for example, corresponds to a display color of a display on the HF generator 20.
