Description

Elektrochirurgisches System und elektrochirurgisches Instrument zur Verwendung in einem System  Electrosurgical system and electrosurgical instrument for use in a system
Die Erfindung betrifft ein elektrochirurgisches System, ein Verfahren zum Betrieb eines elektrochirurgischen Instruments, ein elektrochirurgisches Instrument zur Verwendung in einem elektrochirurgischen System sowie einen Generator zum Betrieb eines elektrochirurgischen Instruments. Elektrochirurgische Systeme und Instrumente hierfür sind bekannt, beispielsweise aus der US 5,931 ,836 und der DE 10 2009 041 329 A1. In den bekannten Systemen wird ein elektrochirurgisches Instrument zum Betrieb an einen Generator angeschlossen. DE 100 57 585 A1 beschreibt ein Instrument, auf dem instrumentenspezifische Konfigurationsdaten gespeichert sind. Die existierenden Systeme, Verfahren, Instrumente und Generatoren zum Betrieb elekt- rochirurgischer Instrumente bieten verschiedene Vorteile, jedoch sind weitere Verbesserungen wünschenswert. The invention relates to an electrosurgical system, a method of operating an electrosurgical instrument, an electrosurgical instrument for use in an electrosurgical system, and a generator for operating an electrosurgical instrument. Electrosurgical systems and instruments for this purpose are known, for example from US Pat. Nos. 5,931,836 and DE 10 2009 041 329 A1. In the known systems, an electrosurgical instrument is connected to a generator for operation. DE 100 57 585 A1 describes an instrument on which instrument-specific configuration data are stored. The existing systems, methods, instruments and generators for operating electrosurgical instruments offer several advantages, but further improvements are desirable.
Es ist daher Aufgabe der vorliegenden Erfindung, ein elektrochirurgisches System, ein elektrochirurgisches Instrument zur Verwendung in einem elektrochirurgischen System, ein Verfahren zum Betrieb eines elektrochirurgischen Instruments sowie einen Generator zum Betrieb eines elektrochirurgischen Instruments anzugeben, welche gegenüber existierenden Systemen, Verfahren, Instrumenten und Generatoren verbessert sind. It is therefore an object of the present invention to provide an electrosurgical system, an electrosurgical instrument for use in an electrosurgical system, a method of operating an electrosurgical instrument, and a generator to provide for the operation of an electrosurgical instrument, which are improved over existing systems, methods, instruments and generators.
Diese Aufgabe wird gelöst durch ein elektrochirurgisches System, umfassend ein elektro- chirurgisches Instrument, einen Generator, welcher zum Betrieb des elektrochirurgischen Instruments ausgebildet ist, ein Speicherelement, auf dem wenigstens eine bedienungsrelevante Information, die wenigstens eine Bedienungsanleitung für das elektrochirurgi- sche Instrument repräsentiert, gespeichert ist, und eine Anzeige, welche ausgebildet ist, die bedienungsrelevante Information anzuzeigen, wobei das System ausgebildet ist, die bedienungsrelevante Information an die Anzeige zu übertragen. Das erfindungsgemäße System beruht unter anderem auf der Erkenntnis, dass Verbesserungen erzielt werden können, wenn bedienungsrelevante Informationen zu einem elektrochirurgischen Instrument auf einem Speicherelement des Systems gespeichert werden. Bei den aus dem Stand der Technik bekannten Systemen werden Bedienungsanleitungen dem Instrument in Papierform beigefügt. So werden die Bedienungsanleitun- gen in Papierform von den Anwendern der Systeme häufig als Bestandteil der Lieferverpackung wahrgenommen und nach dem Auspacken des Instruments entsorgt. Alternativ werden Bedienungsanleitungen häufig archiviert. Diese Vorgehensweise führt dazu, dass die Bedienungsanleitung im Bedarfsfall, beispielsweise während eines klinischen Eingriffs, gar nicht oder nur nach vorheriger Abfrage des Archivs zur Verfügung stehen. Die bedienungsrelevanten Informationen müssen dann entweder neu ermittelt (bei Entsorgung oder Verlust) oder aus einem Archiv angefordert werden. Beides ist zeitintensiv und stellt ein erhebliches Risiko für den zu behandelnden Patienten dar. Fehlende oder falsch zugeordnete bedienungsrelevante Informationen können zu Fehlbedienungen der Instrumente führen, was ebenfalls mit erheblichen Risiken für den Patienten verbunden ist. Das erfindungsgemäße System löst diese Probleme und Herausforderungen dadurch, dass die bedienungsrelevanten Informationen innerhalb des Systems elektronisch auf einem Speicherelement des Systems gespeichert werden und von dort unmittelbar und jederzeit abrufbar sind. Die abgerufenen Informationen werden auf einer Anzeige des Systems angezeigt und können so durch einen Anwender des Systems (beispielsweise ein behandelnder Arzt) interpretiert und angewendet werden. Eine Fehlzuordnung kann sicher vermieden werden. This object is achieved by an electrosurgical system, comprising an electrosurgical instrument, a generator, which is designed to operate the electrosurgical instrument, a memory element, on which at least one user-relevant information, which represents at least one operating manual for the electrosurgical instrument, is stored, and a display, which is adapted to display the operation-relevant information, wherein the system is adapted to transmit the operation-relevant information to the display. Among other things, the system according to the invention is based on the recognition that improvements can be achieved if user-relevant information on an electrosurgical instrument is stored on a memory element of the system. In the systems known from the prior art operating instructions are attached to the instrument in paper form. For example, the user manuals in paper form are often perceived by users of the systems as part of the delivery packaging and disposed of after unpacking the instrument. Alternatively, manuals are often archived. This procedure means that the operating instructions are not available at all, if necessary, for example during a clinical procedure, or only after prior consultation of the archive. The user-relevant information must then either be newly determined (in case of disposal or loss) or requested from an archive. Both are time-consuming and represent a considerable risk for the patient to be treated. Missing or misaligned user-relevant information can lead to incorrect operation of the instruments, which is also associated with considerable risks for the patient. The system according to the invention solves these problems and challenges by virtue of the fact that the information relevant for operation within the system is stored electronically on a memory element of the system and can be called up there immediately and at any time. The retrieved information is displayed on a display of the system and can thus be interpreted and applied by a user of the system (for example, a treating physician). A misallocation can be safely avoided.
Erfindungsgemäß werden die bedienungsrelevanten Informationen in elektronischer Form auf einem Speicherelement zur Verfügung gestellt. Dies hat den Vorteil, dass die Handhabbarkeit der Informationen verbessert wird. So können beispielsweise Suchfunktionen und Interaktionen durch eine computerbasierte Bereitstellung und Aufbereitung der bedienungsrelevanten Information an die Anzeige ermöglicht werden. According to the invention, the user-relevant information is provided in electronic form on a memory element. This has the advantage that the Handling of the information is improved. For example, search functions and interactions can be made possible by a computer-based provision and processing of the information relevant to the operation of the display.
Das erfindungsgemäße System ist vorzugsweise für den Betrieb eines elektrochirurgi- sehen Handinstruments geeignet. The system according to the invention is preferably suitable for the operation of an electrosurgical hand instrument.
Der Generator umfasst bevorzugt einen Ultraschallgenerator mit einer Erzeugungseinheit zum Bereitstellen eines Erregersignals, mit dem ein Ultraschallwandler eine Ultraschallvibration erzeugen kann. Zusätzlich oder alternativ umfasst der Generator vorzugsweise einen Hochfrequenz-Generator zum Bereitstellen eines Hochfrequenzsignals an zwei Ausgangskontakten des Generators. Für den Betrieb des elektrochirurgischen Instruments stellt der Generator an seinen Ausgangskontakten ein Betriebssignal zur Verfügung, welches von dem elektrochirurgischen Instrument verarbeitet wird. Die Übertragung des Betriebssignals an das Instrument erfolgt beispielsweise über eine Kabelverbindung des Instruments. Die Kabelverbindung umfasst vorzugsweise einen Stecker, welcher in die Ausgangskontakte eingesteckt werden kann. The generator preferably comprises an ultrasound generator with a generating unit for providing an exciter signal with which an ultrasound transducer can generate an ultrasound vibration. Additionally or alternatively, the generator preferably comprises a high frequency generator for providing a high frequency signal to two output contacts of the generator. For the operation of the electrosurgical instrument, the generator provides at its output contacts an operating signal which is processed by the electrosurgical instrument. The transmission of the operating signal to the instrument takes place, for example, via a cable connection of the instrument. The cable connection preferably comprises a plug which can be plugged into the output contacts.
Das Betriebssignal umfasst vorzugsweise das Erregersignal und das Hochfrequenzsignal. Das Erregersignal wird mittels eines im Instrument vorhandenen Ultraschallwandlers in eine Ultraschallvibration umgewandelt, die zur Behandlung des Gewebes eines Patienten verwendet werden kann. Das Hochfrequenzsignal kann gemäß der vorliegenden Erfindung für monopolare und/oder bipolare Anwendungen bereitgestellt werden. Bei monopolaren Anwendungen weist das elektrochirurgische Instrument eine Elektrode auf, die mit einem der Ausgangskontakte, an welchem das Hochfrequenzsignal bereitgestellt wird, verbunden ist. Gleichzeitig umfasst das System eine Patientenelektrode, die mit einem anderen der beiden Ausgangskontakte, an welchem das Hochfrequenzsignal bereitgestellt ist, verbunden ist. Während des Betriebs des elektrochirurgischen Instruments, wird die Elektrode mit dem zu behandelnden Gewebe in Kontakt gebracht. Die Patientenelektrode ist beispielsweise mit einem Abschnitt der Haut des Patienten verbunden. Auf diese Weise erzeugt das Hochfrequenzsignal einen Strom, der durch einen Bestandteil des Körpers von der Elekt- rode zur Patientenelektrode hin- und zurückfließt. The operating signal preferably comprises the exciter signal and the high-frequency signal. The excitation signal is converted by means of an ultrasonic transducer present in the instrument into an ultrasonic vibration, which can be used to treat the tissue of a patient. The high frequency signal may be provided in accordance with the present invention for monopolar and / or bipolar applications. In monopolar applications, the electrosurgical instrument has an electrode connected to one of the output contacts to which the radio frequency signal is provided. At the same time, the system includes a patient electrode connected to another of the two output contacts to which the radio frequency signal is provided. During operation of the electrosurgical instrument, the electrode is brought into contact with the tissue to be treated. For example, the patient electrode is connected to a portion of the patient's skin. In this way, the high frequency signal generates a current that flows back and forth through a component of the body from the electrode to the patient electrode.
Bei bipolaren Anwendungen hat das elektrochirurgische Instrument mindestens zwei Elektroden, wobei jede Elektrode mit einem der beiden Ausgangskontakte, an welchen das Hochfrequenzsignal bereitgestellt wird, verbunden ist. In einer solchen bipolaren Anwendung fließt der elektrische Strom durch das Gewebe, welches zwischen den zwei Elektroden des elektrochirurgischen Instruments und in Kontakt mit diesen liegt. Das elektrochirurgische Instrument kann dabei z.B. zwei Schenkel mit jeweils einer Elektrode oder einen stabförmigen Applikator mit zwei in axialer Richtung beabstandeten Elektroden aufweisen. In bipolar applications, the electrosurgical instrument has at least two electrodes, each electrode having one of the two output contacts to which the radio frequency signal is provided is connected. In such a bipolar application, the electrical current flows through the tissue which lies between and in contact with the two electrodes of the electrosurgical instrument. In this case, the electrosurgical instrument can, for example, have two limbs each with one electrode or a rod-shaped applicator with two electrodes spaced apart in the axial direction.
Wenn das Hochfrequenzsignal im Frequenzbereich der Mikrowellen bereitgestellt wird, kann das elektrochirurgische Instrument an Stelle einer oder mehrerer Elektroden, oder zusätzlich hierzu, eine Mikrowellenantenne umfassen. Unter den Begriff „bedienungsrelevante Information" fallen im Rahmen der vorliegenden Erfindung unter anderem sämtliche Anleitungs- und Anweisungsinformationen, welche die bestimmungsgemäße und sichere Bedienung, Gebrauch, Verwendung, Anwendung, etc. des elektrochirurgischen Instruments durch einen Benutzer betreffen. So umfassen bedienungsrelevante Informationen beispielsweise sämtliche Informationen, die in ge- druckten Bedienungsanleitungen oder Gebrauchsanweisungen vorzufinden sind, können vorzugsweise jedoch weitere Informationen enthalten, die in gedruckter Form nicht bereitgestellt werden können, beispielsweise Animationen oder Filme. When the radio frequency signal is provided in the frequency range of the microwaves, the electrosurgical instrument may comprise, instead of or in addition to, one or more electrodes, a microwave antenna. In the context of the present invention, the term "user-relevant information" encompasses, inter alia, all instruction and instruction information relating to the intended and safe operation, use, use, application, etc. of the electrosurgical instrument by a user However, information found in printed manuals or instructions for use may preferably contain other information that can not be provided in printed form, such as animations or movies.
Der Begriff „Speicherelement" ist im Rahmen der vorliegenden Erfindung vorzugsweise als ein permanenter oder semi-permanenter elektronischer Speicher zu verstehen. So kann das Speicherelement vorzugsweise einen Flash-EEPROM (Erasable Programmable Read Only Memory) umfassen oder aus diesem bestehen. Die betriebsrelevanten Informationen sind auf dem Speicherelement vorzugsweise in Form von Daten gespeichert. Die Anzeige ist vorzugsweise ausgebildet, die Daten zu interpretieren und für die Anzeige aufzubereiten. Das erfindungsgemäße System betrifft die Anwendung von elektrochirurgischen Instrumenten und Generatoren sowie Verfahren zum Betrieb solcher Instrumente und Generatoren. Für das Verständnis der Erfindung wird das erfindungsgemäße System im Folgenden in Bezug auf ein System aus kombiniertem Ultraschall- und Hochfrequenz-Generator und einem von dem Generator betriebenen elektrochirurgischen Instrument beschrieben. Die Erfindung ist jedoch gleichermaßen für elektrochirurgische Systeme, elektrochirurgische Instrumente, Generatoren und Verfahren anwendbar, die nur Ultraschall oder nur Hochfrequenz einsetzen. Das System ist vorzugsweise ausgebildet, die bedienungsrelevanten Informationen zu übertragen, während die Anzeige signaltechnisch mit dem Speicherelement gekoppelt ist. Das signaltechnische Koppeln der Anzeige mit dem Speicherelement kann draht- bzw. kabelgebunden oder draht- bzw. kabellos, vorzugsweise mittels Nahfeldkommunikation, erfolgen. Das drahtgebundene Koppeln kann beispielsweise mittels der Kabelverbindung des Speicherelements erfolgen, sobald diese mit ihrem Stecker in Ausgangskontakte der Anzeige oder einer Einrichtung, deren Element die Anzeige bildet, gesteckt wird. Für eine Nahfeldkommunikation kann das Speicherelement vorzugsweise ein RFID-Element umfassen oder aus diesem bestehen. Die auf dem Speicherelement gespeicherte bedie- nungsrelevante Information kann mittels einer Funkschnittstelle der Anzeige oder einer Einrichtung, deren Element die Anzeige bildet, von dem RFID-Element (RFID: Radiofrequency Identification) ausgelesen werden. Das RFID-Element kann von einem RFID-Transponder gebildet sein. Die Funkschnittstelle der Anzeige oder der Einrichtung sendet dabei vorzugsweise ein elektromagnetisches Wechselfeld aus, welches durch den RFID-Transponder beeinflusst wird. Mittels der Funkschnittstelle werden reflektierte Wellen des elektromagnetischen Wechselfeldes empfangen und auf dem RFID- Transponder gespeicherte Informationen aus der Beeinflussung des Wechselfeldes entnommen. Auf diese Weise kann die Identifikationsinformation bei dem signaltechnischen Koppeln an die Anzeige übertragen werden. Das signaltechnische Koppeln ist als direktes und indirektes signaltechnisches Koppeln zu verstehen. Bei einem indirekten signaltechnischen Koppeln ist bzw. sind vorzugsweise ein Element bzw. mehrere Elemente zwischen Anzeige und Speicherelement geschaltet. So kann die Anzeige beispielsweise eine Steuereinheit aufweisen, welche direkt mit dem Speicherelement des erfindungsgemäßen Systems gekoppelt ist (in diesem Sinne ist die Anzeige indirekt über die Steuereinheit mit dem Speicherelement gekoppelt). In the context of the present invention, the term "memory element" is preferably to be understood as a permanent or semi-permanent electronic memory, for example, the memory element may comprise or consist of an Erasable Programmable Read Only Memory (EEPROM) The display is preferably designed to interpret the data and process it for display The system according to the invention relates to the use of electrosurgical instruments and generators as well as methods of operating such instruments and generators In the present invention, the system of the present invention will be described with reference to a combined ultrasonic and high frequency generator system and an electrosurgical instrument operated by the generator, however, the invention is equally applicable to electrosurgery systems, electrosurgical instruments, generators and methods that use only ultrasound or only radio frequency. The system is preferably designed to transmit the service-relevant information, while the display is signal-wise coupled to the memory element. The signal-technical coupling of the display with the memory element can be wired or wired or wired or wireless, preferably by means of near-field communication. The wired coupling can take place, for example, by means of the cable connection of the storage element as soon as it is inserted with its plug into output contacts of the display or a device whose element forms the display. For a near field communication, the memory element may preferably comprise or consist of an RFID element. The service-relevant information stored on the storage element can be read out by the RFID element (RFID: Radio Frequency Identification) by means of a radio interface of the display or a device whose element forms the display. The RFID element can be formed by an RFID transponder. The radio interface of the display or the device preferably emits an electromagnetic alternating field, which is influenced by the RFID transponder. By means of the radio interface, reflected waves of the electromagnetic alternating field are received and information stored on the RFID transponder is taken from the influence of the alternating field. In this way, the identification information can be transmitted in the signal-technical coupling to the display. The signaling coupling is to be understood as a direct and indirect signal-technical coupling. In an indirect signaling coupling is or are preferably one element or more elements between display and memory element connected. For example, the display may have a control unit which is directly coupled to the memory element of the system according to the invention (in this sense the display is indirectly coupled to the memory element via the control unit).
Weiter vorzugsweise umfasst das erfindungsgemäße System eine Bedieneinheit (beispielsweise eine Computereinheit) zum Aufbereiten, Bearbeiten, Durchsuchen der und/oder Interagieren mit den angezeigten betriebsrelevanten Informationen. Further preferably, the system according to the invention comprises an operating unit (for example a computer unit) for editing, editing, searching and / or interacting with the displayed operationally relevant information.

Das Speicherelement des erfindungsgemäßen Systems bildet nach dieser Ausführungsform also einen Bestandteil des elektrochirurgischen Instruments, welches in dem System betrieben werden kann. Das Speicherelement ist vorzugsweise in einem Handteil des elektrochirurgischen Instruments angeordnet. Alternativ und/oder zusätzlich ist das Speicherelement weiter vorzugsweise in dem Stecker des elektrochirurgischen Instruments angeordnet. Die Anordnung in dem Stecker des elektrochirurgischen Instruments hat den Vorteil, dass eine geringere Reichweite für die Datenübertragung zwischen Speicherelement und Generator erforderlich ist. Zudem kann eine höhere Datenrate erzielt werden. According to a preferred embodiment of the system according to the invention, the electrosurgical instrument has the storage element. The memory element of the system according to the invention therefore forms, according to this embodiment, a component of the electrosurgical instrument which can be operated in the system. The storage element is preferably arranged in a handpiece of the electrosurgical instrument. Alternatively and / or additionally, the storage element is further preferably arranged in the plug of the electrosurgical instrument. The arrangement in the plug of the electrosurgical instrument has the advantage that a shorter range for the data transmission between memory element and generator is required. In addition, a higher data rate can be achieved.
Ein wesentlicher Vorteil dieser Ausführungsform besteht darin, dass die bedienungsrelevante Information vom Instrument selbst abrufbar ist. Dadurch ist die bedienungsrelevante Information unabhängig davon, in welchem System oder mit welchem Generator das Instrument betrieben wird, zugänglich.
