Abstract
Description
Die Erfindung betrifft ein hochfrequenzchirurgisches Multifunktions-Handinstrument zum bipolaren Koagulieren und Schneiden sowie zum Spülen des Operationsgebietes und zum Absaugen von Flüssigkeit und Gewebeteilchen bei endoskopi schen Operationen, welches an einen Hochfrequenzgenerator sowie Spül- und Saugmittel anschließbar ist.The invention relates to a high-frequency surgical Multifunctional hand instrument for bipolar coagulation and Cutting as well as flushing the surgical area and Aspiration of fluid and tissue particles at endoskopi operations, which is connected to a high-frequency generator as well as detergent and suction can be connected.
Heutzutage werden immer mehr medizinische Operationen laparoskopisch im Körperinnern minimal invasiv so durchge führt, daß zunächst Trokare, das sind Rohre mit einem Durch messer von z. B. 5 bis 10 mm, von außen in das Körperinnere eingeführt werden, um Zugangskanäle zu schaffen, durch die ein Endoskop, ein hochfrequenzchirurgisches Handinstrument, eine Spül- oder Absaugsonde etc. eingeführt werden können, um damit an das Operationsgebiet zu gelangen. Dabei werden vorzugsweise ein Optiktrokar und mehrere Arbeitstrokare benutzt. Bei gynokologischen Eingriffen ist das Optiktrokar oft noch mit einem Arbeitskanal ausgerüstet. Ein Problem beim endoskopischen Arbeiten ist der häufige, zeitaufwendige Wechsel der Arbeitsinstrumente für die verschiedenen chirur gischen Tätigkeiten.Nowadays medical operations are becoming more and more common laparoscopic minimally invasive inside the body leads to trocars, which are tubes with a through knife from z. B. 5 to 10 mm, from the outside into the body be introduced to create access channels through which an endoscope, a high-frequency surgical hand instrument, a flushing or suction probe etc. can be inserted, to get to the operating area. In doing so preferably an optical trocar and several working trocars used. With gynocological interventions, the optic trocar is often equipped with a working channel. A problem endoscopic work is the most common, time consuming Change of working tools for the different surgeons activities.
Das Ziel der Erfindung besteht darin, ein hochfrequenz chirurgisches Handinstrument der eingangs genannten Gattung zu schaffen, welches universell für Koagulieren, Schneiden, Spülen und Saugen verwendbar ist und sich in besonderem Maße für die Verwendung im Zusammenhang mit einem Trokar eignet.The aim of the invention is a high frequency surgical hand instrument of the type mentioned to create which is universal for coagulation, cutting, Rinsing and vacuuming can be used and is particularly useful suitable for use in connection with a trocar.
Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß in einem gemeinsamen, durch ein Trokar an das Operationsgebiet bringbaren Schutzrohr mit Handgriff nebeneinander und vor zugsweise parallel zueinander untergebracht sind:To achieve this object, the invention provides that in a common, through a trocar to the operation area bringable protective tube with handle next to each other and in front are preferably housed parallel to each other:
- - eine Hochfrequenz-Koagulationssonde mit zwei Koagulationselektroden;- a high frequency coagulation probe with two Coagulation electrodes;
- - eine Hochfrequenz-Schneidsonde mit einer Schneidnadel oder Schneidschlinge und einer dagegen isolierten Gegenelektrode;- a high-frequency cutting probe with a cutting needle or cutting loop and one isolated against it Counter electrode;
- - ein Spülrohr und- a flushing pipe and
- - ein Saugrohr, wobei- An intake manifold, where
die Hochfrequenz-Koagulationssonde und die Hochfrequenz- Schneidsonde wahlweise aus dem Schutzrohr nach vorne in eine Arbeitsstellung herausschiebbar. Das Spülrohr und das Saug rohr sind zweckmäßigerweise fest im Schutzrohr angebracht.the high-frequency coagulation probe and the high-frequency Cutting probe optionally from the protective tube forward into one Working position can be pushed out. The flushing pipe and the suction Pipe are conveniently fixed in the protective tube.
Auf diese Weise können ohne Auswechslung des einmal in ein Trokar eingeführten Instrumentes sowohl Hochfrequenzkoagula tionen als auch Hochfrequenzschneidvorgänge durchgeführt wer den, und es ist außerdem ein Spülen des Operationsgebietes sowie ein Absaugen von dort befindlichen Flüssigkeiten und Gewebeteilchen möglich. Der Operateur muß hierzu lediglich die verschiedenen Sonden durch geeignete Bedienung des Hand instruments aktivieren und die elektrischen und hydrauli schen Ströme in der erforderlichen Weise ein- bzw. ausschal ten. Auf diese Weise können mit dem erfindungsgemäßen Hand instrument praktisch sämtliche elektrochirurgischen Operatio nen ohne Auswechslung des Instruments durchgeführt werden.This way, without changing the once in a Trocar introduced instrument both high-frequency coagula tion as well as high-frequency cutting operations den, and it is also a flushing of the surgical area as well as suction of liquids located there and Tissue particles possible. The operator only needs to do this the various probes by operating the hand appropriately activate instruments and the electrical and hydraulic currents on or off in the required manner In this way, with the hand according to the invention instrument practically all electrosurgical operations be carried out without changing the instrument.
Vorteilhafte Weiterbildungen der Erfindung sind durch die Unteransprüche gekennzeichnet.Advantageous further developments of the invention are provided by Subclaims marked.
Die Erfindung wird im folgenden beispielsweise anhand der Zeichnung beschrieben, deren einzige Figur eine perspektivi sche Ansicht eines erfindungsgemäßen hochfrequenzchirurgi schen Handinstruments zeigt.The invention is described below, for example, with the aid of Described drawing, the only figure a perspective cal view of a high-frequency surgery according to the invention shows hand instruments.
Nach der Zeichnung schließt sich an einen Handgriff 12 nach vorn ein Schutzrohr 11 an, in welchem nebeneinander und parallel zueinander eine Hochfrequenz-Koagulationssonde 13 mit zwei aufeinanderzu- und voneinander wegbewegbaren, gegen einander isolierten Koagulationselektroden 14, 15, eine Hochfrequenz-Schneidsonde 16 mit einer Schneidnadel 17 und einer dagegen isolierten, als Gegenelektrode wirkenden Um hüllung 18, ein Spülrohr 19 und ein Saugrohr 20 angeordnet sind.According to the drawing, a protective tube 11 is connected to a handle 12 to the front, in which a high-frequency coagulation probe 13 with two coagulation electrodes 14 , 15 , a high-frequency cutting probe 16 with one that can be moved towards and away from one another and parallel to one another, can be moved next to and parallel to one another Cutting needle 17 and an insulated against it, acting as a counter electrode to cover 18 , a rinsing tube 19 and a suction tube 20 are arranged.
Das Spülrohr 19 und das Saugrohr 20 sind beim Ausführungs beispiel fest im Schutzrohr 11 angeordnet und erstrecken sich im wesentlichen bis zur Mündung desselben.The rinsing tube 19 and the suction tube 20 are fixedly arranged in the embodiment in the protective tube 11 and extend substantially to the mouth of the same.
Die Hochfrequenz-Koagulationssonde 13 und die Hochfrequenz- Schneidsonde 16 sind dagegen mittels im Handgriff 12 angeord neter Betätigungsschieber 21 bzw. 22 aus dem vorderen Ende des Schutzrohres 11 herausschiebbar, um so in ihre Arbeits stellung zu gelangen. In der Zeichnung ist die Hochfrequenz- Koagulationssonde 13 in der mittels des ihr zugeordneten Schiebers 22 in die Arbeitsstellung vorgeschobener Position dargestellt. Die Schneidelektrode 16 ist dagegen ebenso wie der ihr zugeordnete Schieber 21 in der hinteren bzw. einge zogenen Stellung veranschaulicht.The high-frequency coagulation probe 13 and the high-frequency cutting probe 16 , on the other hand, can be pushed out by means of actuating slides 21 and 22 arranged in the handle 12 from the front end of the protective tube 11 , in order to get into their working position. In the drawing, the high-frequency coagulation probe 13 is shown in the position advanced by means of the slide 22 assigned to it into the working position. The cutting electrode 16 , however, is illustrated, as is the slide 21 assigned to it, in the rear or retracted position.
