Descripción  traducido del alemán

Die Erfindung betrifft ein elektrochirurgisches Operations werkzeug zum Einsatz im Gebiet der Elektrochirurgie (Diather mie) die bei verschiedenen chirurgischen Operationsverfahren eingesetzt wird, bei offenen ebenso wie bei sogenannten lapa roskopischen Operationen. The invention relates to an electrosurgical tool operations for use in the field of electrosurgery (Diather mie) which is used in various surgical operation method in open as well as in so-called Lapa roskopischen operations.

Elektrochirurgische Operationswerkzeuge werden bislang als mo nopolare oder bipolare Werkzeuge konzipiert. Electrosurgical surgical tools are designed as far mo nopolare or bipolar tools. Bei monopolaren Werkzeugen ist die Konfiguration so gewählt, daß eine separate Neutral-Elektrode mit dem Patienten verbunden ist, wobei sich nur ein elektrischer Pol an dem Werkzeug befindet. In monopolar tools, the configuration is chosen such that a separate neutral electrode is connected to the patient, wherein only one electrical pole is located on the tool. Dahingegen ist die Konfiguration eines bipolaren Werkzeugs derart, daß sich beide elektrischen Pole an dem Werkzeug befinden. In contrast, the configuration of a bipolar tool is such that the two electric poles located on the tool. Monopo lare wie bipolare Elektrochirurgie-Werkzeuge bieten dem Opera teur jeweils bestimmte Vor- und Nachteile. Monopo lar as bipolar electrosurgical tools provide the Opera thousand each specific advantages and disadvantages. Bei bestimmten chi rurgischen Eingriffen ist es sinnvoll, beide elektrochirurgi schen Operationswerkzeugtypen einzusetzen. In certain chi rurgischen procedures, it is useful to use both elektrochirurgi rule surgical tool types. Üblich ist ein häu figer Wechsel der beiden Operationsmethoden und der entspre chenden elektrochirugischen Instrumente. Common operating system is frequently circuitous exchange of the two methods of operation and the corre sponding electrosurgical instruments.

In der DE 196 50 150 A1 ist eine bipolare elektrochirurgische Schere beschrieben. In DE 196 50 150 A1 discloses a bipolar electrosurgical scissors is disclosed. Dadurch ist diese Schere besonders dazu geeignet, nach dem Schnitt auftretende Blutungen durch einen elektrochirurgischen Strom (Koagulation) zu stillen (Hämosta se). Thus, these scissors is particularly adapted occurring after the cut bleeding by an electrosurgical current (coagulation) (se Hämosta) to breastfeed.

Die DE 39 37 700 A1 beschreibt eine bipolare Koagulationspin zette, die zum Einschalten des elektrochirurgischen Stromes mit einem Schalter an den Pinzettenschenkeln ausgerüstet ist. DE 39 37 700 A1 describes a bipolar Koagulationspin tweezers, which is equipped for switching on the electrosurgical current to a switch to the tweezer branches.

Es ist weiter zur punktuellen Koagulation bei lokalen Blutun gen als Alternative zum zusätzlichen Einsatz monoplarer Werk zeuge vorgeschlagen worden, die Scherenblätter einer bipolaren Schere zusammenzuhalten, so daß der Stromfluß zwischen den bei den Scherenblättern lokal begrenzt ist. It is further for spot coagulation in local Blutun gene as an alternative to use additional tools monoplarer been proposed to hold the scissor blades of a bipolar scissors, so that the current flow is localized in between the scissor blades.

Je weiter bei den bipolaren Operationswerkzeugen die Schenkel auseinanderstehen, desto stärker ist der elektrische Wider stand des zu verödenden Gewebes. The farther apart the legs are in the bipolar operation tools, the stronger the electrical resistance is state of the tissue to be sclerosed. Die dementsprechende Anpas sung der elektrischen Hochfrequenz- bzw. HF-Spannung ist bis lang nur am HF-Generator per Hand einstellbar, wodurch die Aufmerksamkeit des Operateurs an verschiedenen Arbeitsbereichen gleichzeitig gefordert ist. The corresponding ANPAS measurement of the electrical high-frequency or RF voltage can be set only on the RF generator by hand to long, so that the attention of the surgeon at various work areas is required simultaneously. Darüber hinaus haben diese Elek trochirurgie-Werkzeuge gemeinsam den Nachteil, daß der Opera teur wie erwähnt zur Anwendung der monopolaren Operationsme thode ein anderes Werkzeug einsetzen muß. In addition, these Elek trochirurgie tools have in common the disadvantage that the Opera thousand as mentioned method for the application of monopolar Operationsme must use a different tool. Der unvermeidliche Zeitverlust ist medizinisch bedenklich und ineffizient. The inevitable loss of time is medically questionable and inefficient.

Es besteht daher die Aufgabe, elektrochirurgische Operations werkzeuge zu schaffen, welche dem Operateur die Möglichkeit geben, während der Operation schnell und einfach von dem einen zum anderen elektrochirugischen zu wechseln. There is therefore the task of creating electrosurgical Operations tools, which give the operator the opportunity during the operation to switch easily from one to the other electrosurgical.

Weiterhin anzustreben ist die Anpassung des elektrochirurgi schen HF-Stromes an den jeweiligen elektrischen Widerstand des zu verödenden Gewebes soweit wie möglich zu automatisieren, damit der Operateur sich optimal auf den Patienten konzentrie ren kann. Furthermore, the aim should be to adapt the rule elektrochirurgi RF current to the respective electrical resistance of the tissue to be sclerosed as much as possible to automate, so the surgeon can optimally to the patient concentrating ren.

Diese Aufgabe ist erfindungsgemäß bei einem elektrochirurgi schen Werkzeug mit den Merkmalen des Anspruchs 1 gelöst. This object is achieved according to the invention in a elektrochirurgi rule tool with the features of claim 1. Vor teilhafte Weiterbildungen des erfindungsgemäßen Werkzeuges sind Gegenstand der Unteransprüche. Before some refinements of the tool according to the invention are the subject of the dependent claims.

Ein elektrochirurgisches Operationswerkzeug zeichnet sich so mit dadurch aus, daß seine Elektrodenanschlüsse für den Ein satz in der monopolaren und der bipolaren Betriebsart vorgese hen sind. An electrosurgical operation tool is characterized as having by the fact that its electrode terminals for use in con monopolar and bipolar mode are vorgese hen. Zweckmäßig ist ein elektrischer Schalter für die Um schaltung zwischen der monopolaren und der bipolaren Betrieb sart vorgesehen. Advantageously, an electrical switch for switching between the order of monopolar and bipolar operation is sart provided.

Auf diese Weise kann sowohl monopolarer als auch bipolarer HF-Strom eingesetzt werden, indem zwischen monopolarem und bi polarem HF-Strom umgeschaltet wird. In this way, both monopolar and bipolar RF current can be used by between monopolar and bi-polar RF current is switched. So kann der Operateur je nach den Erfordernissen zwischen den beiden elektrochirurgi schen Operationsmethoden hin- und herzuschalten. Thus, the surgeon can switch back and forth depending on the requirements between the two elektrochirurgi's operation methods.

Zweckmäßig ist am Operationswerkzeug ein elektrischer Schalter angebracht, der die Umschaltung zwischen den beiden elektro chirurgischen Operationsmethoden ermöglicht. Suitably, an electrical switch is mounted on the surgical tool, which enables the switching between the two electro-surgical operation methods. Grundsätzlich ist denkbar, daß diese Umschaltung auch anders, beispielsweise über ein Fußpedal gestellt wird. Basically, it is conceivable that this switch is set differently, for example via a foot pedal.

Eine günstige Weiterentwicklung der Erfindung besteht darin, daß eine Schaltmöglichkeit am Operationswerkzeug angebracht ist, mit welcher der Operateur das Ein-/Ausschalten des elek trochirurgischen Stromes vornehmen kann. A favorable development of the invention is that a switching option is attached to the surgical tool with which the surgeon can perform the switching on / off the elec trochirurgischen current. Auch dieses Ein-/Aus schalten muß nicht zwingend am Operationswerkzeug durchgeführt werden. Also, turn this on / off must not necessarily be carried out at the surgical tool. Sind aber die wichtigen Schalter für Umschaltung und Ein-/Ausschaltung am Operationswerkzeug angebracht, so kann der Operateur alle wichtigen Steuerungen eigenhändig vorneh men, ohne das Gesicht vom Patienten ab- und technischen Gerä ten zuwenden zu müssen. But the important switch for switching and on / off operation attached to the tool so the operator can control all the important men vorneh hand, without the face off from the patient and technical vices having to turn to. Denkbar ist auch eine Kombination aus Umschalter und Ein-/Ausschalter, die an bestimmte, bereits bestehende Operationswerkzeuge nachgerüstet werden kann. It is also conceivable combination of switch and on / off switch that can be retrofitted to certain existing surgical tools. Ein weiterer, günstiger Nebeneffekt der Erfindung besteht darin, daß für beide elektrochirurgischen Operationsmethoden eine Verkabelung zwischen Operationswerkzeug und HF-Generator aus reicht. Another beneficial side effect of the invention is that for both electrosurgical methods of operation extends a wiring between the surgical tool and RF generator off. Infolgedessen wird die Anhäufung von elektrischen Lei tungen im zentralen Operationsbereich vermindert. As a result, the accumulation of electrical lines Lei is in the central area of operation reduced.

Vorteilhaft ermöglicht die Erfindung auch eine automatischen Anpassung des elektrochirurgischen HF-Stromes an den jewei ligen elektrischen Widerstand des zu verödenden Gewebes vor. Advantageously, the invention enables also an automatic adjustment of the RF electrosurgical current at the time jewei electrical resistance of the tissue to be sclerosed. Diese Anpassung steuert ein Sensor, der den Winkel zwischen den geöffneten Schenkeln des jeweiligen Operationswerkzeuges mißt. This adjustment controls a sensor which measures the angle between the open legs of the respective operational tool. Die so gewonnenen Daten werden von einem Rechner ge nutzt, um die Spannung des elektrochirurgischen HF-Stromes so zu regulieren, daß eine optimale Blutstillung bei minimaler Karbonisierung des verödeten Gewebes erreicht wird. The data thus obtained are ge from a computer uses to regulate the voltage of the RF electrosurgical current so that an optimal hemostasis is achieved with minimal carbonation of the deserted tissue.

Die Erfindung wird im folgenden anhand eines vorteilhaften Ausführungsbeispiels und der Zeichnung beschrieben. The invention will be described below with reference to an advantageous exemplary embodiment and the drawing. Es zeigen: In the drawings:
