Abstract

The electrode hand grip is designed for remote hand switching of a h.f. surgical instrument. Two contact rings are fitted onto a handle piece made of insulating material. Both rings are surrounded by a shaped piece made of elastic, insulating material. This shaped piece has another contact ring set within it. An outer pressure upon one side of the shaped piece causes this ring to simultaneously touch the two separated contact rings to form an electrical connection between them. A light pressure from the inner surface of a finger or thumb is sufficient to switch the surgical instrument on e.g. during a delicate operation.

Description

Elektrodenhandgriff zur Handfernschaltung eines Hochfrequenz-Chirurgiegeräts Gegenstand der Erfindung ist ein Elektrodenhandgriff zur Handfernschaltung eines Hochfrequenz-Chirurgiegeräts, dessen neuartige Konstruktion und besondere Anordnung des Fingerschalters zur Einschaltung des Hochfrequenzchirurgiegeräts den Operateur in die Lage versetzt, bei besonders kritischen und gezielten Eingriffen, insbesondere im tiefliegenden Operationsield oder in der Mundhöhle und bei Verwendung abgewinkelter Qperationselektroden, den Elektrodenhandgriff ähnlich einer Sonde, Markierungsinstruments oder Skalpells zu halten und dabei durch leichten Fingerdruck auf einen auf dem ganzen Umfang des Elektrodenhandgriffs mit gleicher Empfindlichkeit ansprechenden Schalter die Einschaltung des Hochfrequenz-Chirurgiegeräts auszulösen.Electrode handle for manual remote control of a high-frequency surgical device The invention relates to an electrode handle for manual remote control of a High-frequency surgical device, its novel construction and special arrangement of the finger switch to switch on the high-frequency surgical device informs the surgeon put in a position for particularly critical and targeted interventions, in particular in the deep surgical field or in the oral cavity and when using angled Operation electrodes, the electrode handle similar to a probe, marking instruments or to hold scalpels while lightly pressing one on the responding to the entire circumference of the electrode handle with the same sensitivity Switch to activate the high-frequency surgical device.

Zur Hochfrequenz-Chirurgie werden Elektroden in Form von Nadeln, Lanzetten, Messern, Kugeln und Platten verwendet, mit deren Hilfe der lIochfrequenz strom auf den Körper der Patienten geleitet wird. Durch Bildung hoher Stromdichten an den Berührungsstellen der Elektroden mit dem Gewebe wird im Gewebe elektrische Verlustwärme erzeugt, die durch Verdampfen der Zellflüssigkeit das Aufsprengen der Gewebszellen und somit die Gwebstreunung oder Gewebskoagulation bewirkte Zur Halterung der Schneide-oder Koagtilationselektroden werden Elektrodenhandgriffe aus Isolierstoff benützt, die an ihrem vorderen Ende mit einer Spaunvorrichtung für die sichere Fixierung und am hinteren Ende mit einer Steckvorrichtung zum Einstecken des Zuleitungskabels ausgerüste sind.Electrodes in the form of needles, lancets, Knives, balls and plates are used, with the help of which the high-frequency current is raised the body of the patient is directed. By forming high current densities at the Points of contact between the electrodes and the tissue generate electrical heat loss in the tissue which by evaporation of the cell fluid causes the tissue cells to burst open and thus the Gwebstreunung or tissue coagulation caused To hold the cutting or Coagulation electrodes, electrode handles made of insulating material are used at its front end with a spauning device for the safe Fixation and at the rear end with a plug-in device for plugging in the supply cable are equipped.

Zur Durchführung einer rationellen elektrochirurgischen Technik wird von den meisten Operateuren die Möglichkeit verlangt, die Einschaltung des Rochfreqnenz-Chirurgiegeräts direkt vom Elektrodenhandgriff aus zu betätigen, um damit die Einschaltung mittels Fußschalter oder aüf Kornmandu durch eine unsterile Person am Gerät zu umgehen.In order to carry out a rational electrosurgical technique most surgeons are required to be able to switch on the Rochfreqnenz surgical device can be operated directly from the electrode handle in order to switch on using the Foot switch or a Kornmandu by a non-sterile person on the device.

Für die Handfernschaltnng von Hochfrequenz-Chirurgiegeräten sind Elektrodenhandgriffe bekannt, in die ein Momentschalter eingebaut ist und dieser Momentschalter durch einen aus dem Elektrodenhandgriff herausragenden Druckknopf zu betätigen ist. Der Elektrodenhandgriff ist dabei mit einen 2adrigen Zuleitungskabel mit dem Hochfrequenz-Chirurgiegerät verbunden, über das beim Schließen des Momentschalters im Elektrodenhandgriff ein Steuerstromkreis für eine Relaisschaltung geschlossen wird. Dem Steuerstrom wird nach Einschaltung des Hochfrequenz-Chirurgiegeräts die zur lurchführung der Hochfrequenz-Chirurgie notwendige flochfrequenzspannung überlagert und über die Kontakte des Momentschalters der im Elektrodenhandgriff eingespannten Schneide-oder Koagulationselektrode zugeleitet.Electrode handles are used for the manual remote control of high-frequency surgical devices known, in which a momentary switch is built and this momentary switch by a push button protruding from the electrode handle is to be actuated. Of the The electrode handle is connected to the high-frequency surgical device with a 2-core supply cable connected via the one when closing the momentary switch in the electrode handle Control circuit for a relay circuit is closed. The control current is After switching on the high-frequency surgical device, the one to carry out the high-frequency surgery necessary floch frequency voltage superimposed and via the contacts of the momentary switch the cutting or coagulation electrode clamped in the electrode handle.

Es sind auch Elektrodenhandgriffe bekannt, bei denen der eingebaute Momentschalter durch Fingerdruck auf eine Wippe betätigt werden kann.There are also known electrode handles in which the built-in Momentary switch can be operated by finger pressure on a rocker.

Weiterhin sind Elektrodenhandgriffe bekannt, in die eine Spule in axialer Richtung eingebaut und um diese Spule außerhalb des Elektrodenhandgriffs ein offener Ring aus Blechband gelegt ist. Durch Druck auf die offenen Enden des Blechrings wird dieser kurzgeschlossen, die Induktivität der innerhalb liegenden Spule dadurch beeinflusst und ein Steuersignal ausgelöst, das wiederum über eine entsprechende Schaltung anordnung ein Relais zur Einschaltung des Hochfrequenz-Chirurgiegeräts ansprechen lässt.Electrode handles are also known in which a coil in installed in the axial direction and around this coil outside of the electrode handle an open ring made of sheet metal is placed. By pressing on the open ends of the Sheet metal ring this is short-circuited, the inductance lying within Coil influenced and triggered a control signal, which in turn via a Corresponding circuit arrangement of a relay for switching on the high-frequency surgical device can respond.

Alle bekannten Elektrodenhandgriffe zur Handferuschaltung eines Hochfrequenz-Chirurgiegeräts haben den Nachteil, daß sie vom Operateur in einer solch bestimmtem Lage gehalten werden müssen, daß der Finger schalter durch Fingerdruck betätigt werden kann. Der Operateur kann den Elektrodenhandgriff nicht beliebig drehen, er muß ihn immer so halten, daß der von ihm üblicherweise zum Drücken benützte Finger auf dem Druckknopf oder der Schalterwippe liegt. Dies zwingt den Operateur bei Verwendung von abgewinkelten Elektroden sehr oft entweder zu einer Verrenkung seiner Hand oder zur Berichtigung der Elektrodenfixierung.All known electrode handles for hand switching a high-frequency surgical device have the disadvantage that they are kept in such a certain position by the surgeon must be that the finger switch can be operated by finger pressure. Of the The surgeon cannot turn the electrode handle at will, he always has to turn it this way keep that the finger usually used by him to press on the push button or the rocker switch is on. This forces the surgeon to use angled Electrodes very often either to dislocate his hand or to correct it the electrode fixation.

Sehr oft ist beim Vordringen in tiefliegende Operationsbezirke durch enge Wundöffnungen die Betätigung bekannter Handgriffschalter unmöglich. Insbesondere bei elektrochirurgischen Eingriffen in der wundhöhle wird die Handhabung eines Elektrodenhandgriffs in der Weise bevorzugt, wie sie in Abb, 1 dargestellt ist. Der Elektrodenhandgriff wird dabei möglichst weit vorne gefasst, um sichere Elektrodenführung zu gewährleisten. Die Betätigung eines Fingerschalters in einer der bekannten Ausführungen ist dabei nicht möglich.Very often it is through when penetrating into deep-lying operating areas tight wound openings the operation of known handle switches impossible. In particular Electrosurgical interventions in the wound cavity require the use of an electrode handle preferred in the manner shown in fig. The electrode handle is grasped as far forward as possible to ensure safe electrode guidance. The operation of a finger switch in one of the known designs is included not possible.

Vorteil der Erfindung ist nun, daß ein Elektrodenhandgriff mit einem Schalter ausgerüstet ist, der durch leichten Druck auf eine beliebige Stelle auf dem gesamten Griff-Umfang Kontaktschluß bewirkt und die Einschaltung eines Hochfrequenz-Chirurgiegeräts auslöst. Dabei ist der Schalter so gestaltet, daß auch durch leichtes Andrücken einer der Finger-Innenflächen Kontaktschluß erzielt wird. In Abb. 1 ist die Handhabung eines dem Erfindungsgegenstand entsprechenden Elektrodenhandgriffs in einer der möglichen Positionen dargestellt.The advantage of the invention is that an electrode handle with a Switch is equipped with light pressure on any point the entire circumference of the handle causes contact closure and the activation of a high-frequency surgical device triggers. The switch is designed in such a way that it can also be pressed lightly one of the finger inner surfaces contact closure is achieved. In Fig. 1 is the handling an electrode handle corresponding to the subject matter of the invention in one of the possible positions.

Abb. 2 zeigt ein Ausführungsbeispiel der Erfindung: Auf einem mit einer Bohrung versehenen Griffstück aus Isolierstoff 1 ist ein Kontaktring 2 aufgepresst. Ein zweiter Kontaktring 3, dessen eines Ende gleichzeitig angedreht und als Spannzange für die Elektrode 10 ausgebildet ist, ist auf das angedrehte Ende des Griffstücks 1 so aufgeschraubt, daß die Stirnflächen der Kontaktringe 2 und 3 durch einen Luftspalt elektrisch soneinander getrennt bleiben. Das angedrehte Ende des Kontaktrings 3 ist durch das Isolierstück 6 und die Schraubkappe 9 nach außen berührungssicher abgedeckt. Über die Kontaktringe 2 und 3 ist das Gummiformteil 5 geschoben, in das Gummiformteil ist der Kontaktring 4 eingelegt.Fig. 2 shows an embodiment of the invention: On one with a grip piece made of insulating material 1 and provided with a bore, a contact ring 2 is pressed on. A second contact ring 3, one end of which is turned on at the same time and as a collet is designed for the electrode 10, is on the turned end of the handle 1 screwed so that the end faces of the contact rings 2 and 3 through an air gap remain electrically separated from each other. The turned end of the contact ring 3 is safe to touch due to the insulating piece 6 and the screw cap 9 to the outside covered. The molded rubber part 5 is pushed over the contact rings 2 and 3 into the molded rubber part the contact ring 4 is inserted.

Erfolgt nun auf die Mitte des Gumniforinteils 5 ein Druck, dann bewegt sich der Kontaktring 4 in Richtung der Kontaktringe 2 und 3 und bildet zwischen diesen eine elektrische Brücke. Der Durchmesser des Kontaktrings 4 ist so bemessen und das Guumiformteil 5 so elastisch, daß ein geringer Druck in der in Abb. 2 dargestellten Richtung genügt, um die Kontaktringe 2 und 3 elektrisch miteinander zu verbinden. In die Kontaktringe 2 und 3 sind die Leitungen 7 und 8 eingelötet, über die an die Kontaktringe die Steuerspannung für eine Relaisschaltung gelegt ist.If there is now a pressure on the center of the gumniforin part 5, then it is moved the contact ring 4 in the direction of the contact rings 2 and 3 and forms between this one an electrical bridge. The diameter of the contact ring 4 is so dimensioned and the guumiform part 5 so elastic that a slight pressure is shown in FIG Direction is sufficient to electrically connect the contact rings 2 and 3 to one another. In the contact rings 2 and 3, the lines 7 and 8 are soldered, via which to the Contact rings the control voltage for a relay circuit is applied.

Wird der Steuerstromkreis durch Bildung einer elektrischen Verbindung von Kontaktring 2 über Kontaktring 4 zu Kontaktring 5 geschlossen und dadurch ein Hochfrequenz-Chirurgiegerä eingeschaltet, dann fließt ein den Leitungen 7 und 8 überlagerter Hochfrequenzstrom zur Elektrode 10.Becomes the control circuit by forming an electrical connection from contact ring 2 via contact ring 4 to contact ring 5 closed and thereby a The high-frequency surgical device is switched on, then flows into the lines 7 and 8 Superimposed high frequency current to electrode 10.

Der Abstand zwischen der Elektroden-Spannzange mit Schraubkappe 9 und dem Gummiformteil 5 ist so bemessen, daß auch beim Festhalten des Elektrodenliandgriffs mit den Fingerspitzen ganz vorne an der Schraubkappe 9 der zum Kontaktschluß notwendige Druck P mit dem Daumen oder einer der Finger-Innenflächen ausgeübt werden kann.The distance between the electrode collet with screw cap 9 and the rubber molded part 5 is dimensioned so that even when holding the electrode handle with the fingertips at the very front of the screw cap 9 the necessary for contact closure Pressure P can be exerted with the thumb or one of the inner surfaces of the fingers.
