Katheter mit an eine Spannung legbarer SchlingeCatheter with a loop that can be put under tension
Die Neuerung bezieht sich auf einen Katheter mit zum Abtragen, Durchtrennen oder Koagulieren von Geweben dienender,an eine Spannung legbarer Schlinge.The innovation relates to a catheter with used for ablating, cutting or coagulating tissue,to a tension attachable loop.
Zum Abtragen von Geweben,ζ.B.Polypen, Riesenfalten oderErhebungen im Magen unter Verwendung eines flexiblen oder teilflexiblen Gastroskops oder zum Durchtrennen oderKoagulieren von Geweben unter Benutzung entsprechender Endoskope werden mit Hochfrequenzstrom gespeiste Schlingen verwendet,die mit einem durch einen Katheter geführten Leiter an den einen Pol einer Stromquelle angeschlossen werden, während die Operationsstelle entweder über den Körper des Patienten und eine an denKörper gelegte Metallplatte oder der Endoskopschaft als Zuleiter zum anderen Pol der Sbromquelle dient. Bei diesenbekannten Ausführungen können unkontrollierbare Stromübergänge im Körper des Patienten auftreten, die unter Umständensehr gefährlich sind.For removing tissues, e.g. polyps, giant folds orElevations in the stomach using a flexible or partially flexible gastroscope or for severing orTissue coagulation using appropriate endoscopes, loops fed with high frequency current are used,which are connected to one pole of a power source with a conductor passed through a catheter, while the surgical site is either over the patient's body and one to theMetal plate placed on the body or the endoscope shaft serves as a supply line to the other pole of the Sbromquelle. With theseknown designs, uncontrollable current transitions can occur in the patient's body, which under certain circumstancesare very dangerous.
Die Aufgabe der Neuerung besteht darin, solche unkontrollierbaren Stromübergänge auszuschalten, und dies wird nach derThe task of the innovation is to switch off such uncontrollable current transitions, and this will be done after the
Neuerung bei dem eingangs erwähnten Katheter dadurch gelöst, daß die Schlinge in zwei Leiter übergeht, die isoliertdurch den Katheter zum proximalen Katheterende geführt sind.Innovation in the catheter mentioned at the outset is achieved in that the loop merges into two conductors that insulateare passed through the catheter to the proximal end of the catheter.
Bei dieser Lösung der Neuerung kann die z.B. aus Federstahldraht bestehende Schlinge mit Schwachstrom z.B. bis zu6 Volt so beheizt werden, daß sie eine maximale Temperatur von 170° C annimmt, wobei das Schiingenmaterial mindestensam distalen Abschnitt der Schlinge auch so gewählt werden kann, daß sich der spezifische Widerstand bei Temperaturerhöhungnach einer linearen Funktion vergrößert, was zur Temperaturregelung benutzt werden kann. Als Material ist dabei z.B- eineNickel-Eisenlegierung mit.etwa 70 % Nickel und 30 % Eisen verwendbar.With this solution of the innovation, the loop made of spring steel wire, for example, can be used with a low current of up to6 volts are heated so that it assumes a maximum temperature of 170 ° C, the loop material at leastat the distal section of the loop can also be selected so that the specific resistance increases with an increase in temperatureenlarged according to a linear function, which can be used for temperature control. The material here is, for example, aNickel-iron alloy with about 70% nickel and 30% iron can be used.
Anstelle von Schwachstrom ist auch die Verwendung eines bipolaren Hochfrequenzstromes möglich, wobei dann das distaleEnde der Schlinge durch Trennung unterbrochen ist und die Enden isoliert in einem Isolierstück zusammengefaßt sind.Instead of weak current, it is also possible to use a bipolar high-frequency current, the distal current then being usedThe end of the loop is interrupted by separation and the ends are isolated together in an insulating piece.
Durch die Neuerung werden unkontrollierbare Stromübergänge im Körper des Patienten völlig ausgeschaltet, da beide.Leiter der Schlinge zu den beiden Polen der Stromquelle isoliert durch den Katheter geführt sind.The innovation completely eliminates uncontrollable current transitions in the patient's body, since both.Head of the loop to the two poles of the power source are isolated through the catheter.
Die Neuerung wird anhand der Zeichnung kurz erläutert. Es zeigen:The innovation is briefly explained using the drawing. Show it:
Figur 1 eine Seitenansicht eines Katheters mit Abtragschlinge und einen teilweisen Längsschnittdurch das distale Ende des Katheters,FIG. 1 shows a side view of a catheter with an ablation loop and a partial longitudinal sectionthrough the distal end of the catheter,
Figur 2 eine Seitenansicht eines distalen Katheters mit abgeänderter Abtragschlinge, und Schnittdurch das distale Schlingenende.FIG. 2 shows a side view of a distal catheter with a modified ablation loop, and a sectionthrough the distal end of the loop.
Nach dem Beispiel Figur 1 geht die freie, z.B. aus Federstahl-· draht bestehende Schlinge 1 zum Abtragen, Durchtrennen oder Koagulierenvon Geweben in Körperhöhlen in zwei Leiter 2 und 3 über, die isoliert durch den vorteilhaft flexiblen Katheter 4 zum proximalenEnde des Katheters verlaufen und proximal in Stecker 5, 6 enden, mit denen die beiden Leiter2,3 der Schlinge 1 an eineStromquelle anschließbar sind. Als ,Stromquelle wird in diesem Fall vorteilhaft eine Schwachstromquelle verwendet, die z.B. eineSpannung bis zu 6 Volt liefert und in der Lage ist, die Schlinge 1 maximal bis auf eine Temperatur von 170° C aufzuheizen.According to the example in FIG. 1, the free loop 1, for example made of spring steel wire, for removing, cutting or coagulating tissues in body cavities merges into two conductors 2 and 3, which run isolated through the advantageously flexible catheter 4 to the proximal end of the catheter and end proximally in plugs 5, 6 with which the two conductors2, 3 of the loop 1 can be connected to a power source. In this case, the power source used is advantageously a low-power source which, for example, supplies a voltage of up to 6 volts and is capable of heating the loop 1 to a maximum temperature of 170.degree.
Der Katheter 4 mit der Schlinge 1 wird z.B. mittels eines flexiblen oder teilfelxiblen Gastroskops oder eines sonstigenEndoskops an die abzutragenden, zu durchtrennenden oder zu koagulierenden Gewebe·, wie Polypen, Riesenfalten oder ErhebungenThe catheter 4 with the loop 1 is e.g.Endoscope to the tissue to be ablated, severed or coagulated, such as polyps, giant folds or bumps

herangeführt und dann an die Stromquelle angeschlossen, so daß uas Abtragen, Durchtrennen oder Koagulieren von Geweben ohneGefahr für den Patienten durchführbar ist, da durch den isolierten Verlauf beider Leiter durch den Katheter keine unkontrollierbarenStröme im Körper des Patienten auftreten können.brought up and then connected to the power source, so that uas removal, cutting or coagulation of tissues withoutRisk to the patient is feasible, since the insulated path of both conductors through the catheter means that there are no uncontrollable conductorsCurrents can occur in the patient's body.
Es ist auch möglich, die Schlinge gemäß Figur 2 mit bipolarem Hochfrequenzstrom zu beschicken, wobei die SchlingeSjedocham distalen Ende durch Trennung unterteilt ist. Die Schlingenenden sind dabei gegeneinander isoliert in einem Isolierkörperzusammengefaßt. Sonst verlaufen die Leiter 2, 3 zur Schlingeβentsprechend Figur 1 wieder isoliert durch den Katheter 4 zum proximalenEnde und können hier an eine Hochfrequenzstromquelle angeschlossen werden. Auch in diesem Fall können kei.ie Gefahren fürden Patienten auftreten.It is also possible to charge the loop according to FIG. 2 with bipolar high-frequency current, the loopS, however, being subdivided at the distal end. The loop ends are isolated from one another and combined in an insulating body. Otherwise the conductors 2, 3 run to the loopβ in accordance with FIG. 1, again isolated through the catheter 4 to the proximal end and can be connected here to a high-frequency power source. In this case, too, there are no dangers for the patient.
