Description

Einstichelektrode Gegenstand der Erfindung ist eine Einstichelektrode für bio medizinische Zwecke, die es erlaubt, größere Objekte, wie z.B. Elektroden oder Massageköpfe, in Körperbewebe oder Körperhöhlen einzustechen, einzuspritzen, einzublasen oder auch einfließen zu lassen und so die Implantation größerer bzw. weitgespreizter Objekte in Körpergewebe und -höhlen erlaubt, ohne größere eröffnende Operationen, wie dies z.B. am Hirn nur mit folgenschweren Eingriffen möglich wäre, vorzunehmen. Puncture electrode The subject of the invention is a puncture electrode for bio-medical purposes that allow larger objects, such as electrodes or massage heads to pierce or inject into body tissue or body cavities, to be blown in or let in and thus the implantation of larger or larger Widely spread objects in body tissue and cavities are allowed without opening larger ones Operations, such as those on the brain that would only be possible with serious interventions, to undertake.

Es sind Katheder und Sonden bekannt, um tiefer liegende Gewebeschichten von außen her zwecks medizinischer Behandlung zu erreichen.Catheters and probes are known to remove deeper layers of tissue to be reached from the outside for the purpose of medical treatment.

Z.B. ist eine sogenannte Venensperre von Dr. Kazi Mobin-Uddin (Universitä.t Miami) bekannt, mit deren Hilfe man über einen regenschirmartigen Kathederkopf Siebe in Körpervenen einsetzen kann, um zu verhindern, daß Blutgerinsel wandern. Bei diesem Kathederkopf wird also eine Erweiterung der Vene erzielt, um ein Sieb einsetzen zu können.E.g. a so-called vein blocker from Dr. Kazi Mobin-Uddin (Universitä.t Miami), with the help of which sieves can be made over an umbrella-like catheter head insert into veins in the body to prevent blood clots from migrating. With this one Catheter head is thus achieved an enlargement of the vein to insert a sieve to be able to.

Das Gerbt ist hingegen nicht geeignet, größere Objekte als 3 mm Innenraum im Körper zu erfassen und ist einzig und allein auf die Behandlung von Blutgerinseln ausgerichtet. Außerdem ist sie nur zur Einführung in vorhandene Körperhöhlen geeignet, also kein Einstichinstrument.Tanning, on the other hand, is not suitable for objects larger than 3 mm interior space to be captured in the body and is solely due to the treatment from Blood clots aligned. In addition, it is only for introduction into existing body cavities suitable, so not a puncture instrument.

Ferner beschreibt eine Patentschrift aus dem Jahre 1922 -Nr. 360 210 - eine in den Mastdarm einzuführende Elektrode für diathermische Behandlung. Diese Elektrode ist ausschließlich für das Einführen in Körperhöhlen geeignet, also keine Einsti chelektrode.Furthermore, a patent from 1922 describes no. 360 210 - an electrode to be inserted into the rectum for diathermic treatment. These Electrode is only suitable for insertion into body cavities, i.e. none Penetration electrode.

Diese Elektrode kann nur fächerförmig im Körper nach Einbringen verbreitert werden, um ihre Oberfläche zu vergrößern. Die Verbreiterung geschieht nur in der Ebene und nicht im Raum, so daß sie nicht nach allen Richtungen wirken kann und man in der Wahl der Ansetznnöglichkeiten der Gegenelektrode stark begrenzt ist.This electrode can only be widened in a fan shape in the body after it has been introduced to increase their surface area. The broadening happens only in the Level and not in space, so that it cannot work in all directions and one is very limited in the choice of the options for attaching the counter electrode.

Ferner ist der sogenannte "Stark Dilatator" bekannt, der vor allem zur Erweiterung bei Osophagus-Stenose angewandt wurde und welcher lediglich als Sonde 0<atheder) dient.Furthermore, the so-called "Stark dilator" is known, which is primarily for enlargement in oesophageal stenosis and which was only used as Probe 0 <atheder) is used.

Schließlich beschreibt die USA-Patentschrift Nr. 2,739,585 aus dem Jahre 1953 eine in Körperhöhlen einführbare Sonde, also keine Elektrode, auch keine Einstichelektrode. Mit dieser Sonde kann mit Hilfe eines von außen her beweglichen Sondenkopfes ein größerer Bereich im Körperinnern sondiert werden.Finally, U.S. Patent No. 2,739,585 to U.S. Patent No. 2,739,585 1953 a probe that could be inserted into body cavities, so no electrode, not even one Puncture electrode. This probe can be moved from the outside with the help of a A larger area inside the body can be probed with the probe head.

Die vorgenannten bekannten Geräte haben den Nachteil, daß sie nicht in den Körper einstechbar sind und somit nur begrenzt Anwendung finden können.The aforementioned known devices have the disadvantage that they do not can be pierced into the body and can therefore only be used to a limited extent.

Diesen Nachteil beseitigt die vorliegende Erfindung dadurch, daß sie in den Körper einstechbar ist und sämtliche Körperbereiche zu Behandlungszwecken erreichen kann. Dies ist insbesondere für die Behandlung des Gehirnes sowie innerer Organe von großer Wichtigkeit. Vor allem können die Einstechelektroden bis an den Krankheitsherd direkt herangeführt werden, so daß mit einem Minimum an Medikamenten bzw.The present invention overcomes this disadvantage in that it can be pierced into the body and all areas of the body for treatment purposes can reach. This is particular for treating the brain as well as internal Organs of great importance. Above all, the puncture electrodes can reach the Focus of the disease can be brought up directly, so that with a minimum of medication respectively.

Strahlungsintensität ein großer Sehandlungserfolg erzielt werden kann.Radiation intensity a great deal of success can be achieved.

Rein technisch werden hier als Elektroden folgende Medien verwendet: Drähte, leitende Gase, leitende Flüssigkeiten - zurücksaugbar, z .B.Technically, the following media are used here as electrodes: Wires, conductive gases, conductive liquids - can be sucked back, e .g.

Salzlösung - oder supraleitende Kolloide, Strickleitermo leküle usw.Saline solution - or superconducting colloids, rope conductors, etc.

Auch im Körper erstarrende Flüssigkeiten werden als Elektrodenmaterial verwendet. Diese können im Körper verbleiben und durch den Stoffwechsel abgebaut werden. Diese applizierten Elektroden finden Verwendung für Antennen, Heizung für die Kurzwellentherapie, Kauter bzw. als Operationsinstrumente, lonophorese bzw. Kaskadenionophorese für die Tumorzerstörung und schließlich mechanische Vibratoren zur Gewebelockerung und Tumorzerstörung.Liquids that solidify in the body are also used as electrode material used. These can remain in the body and are broken down by the metabolism will. These applied electrodes are used for antennas, heating for shortwave therapy, cautery or as surgical instruments, ionophoresis or Cascade ionophoresis for tumor destruction and finally mechanical vibrators for loosening tissue and destroying tumors.

In den Ausführungsbeispielen werden Lösungen gezeigt, welche rein mechanisch sind oder auch mit Injektionsflüssigkeiten oder Gasen (Edelgasen) verwendet werden oder auch eine Kombination beider Systeme (mechanisch, hydraulisch, pneumatisch) darstellen.In the exemplary embodiments, solutions are shown which are pure are used mechanically or with injection liquids or gases (noble gases) or a combination of both systems (mechanical, hydraulic, pneumatic) represent.

Es zeigen Fig. 1a und ib Spreizelektroden mit schirmartiger Spreizung, Fig. 2 eine Spreizelektrode mit fächerartiger Spreizung, Fig. 3 eine kaskadenförmige Spreizelektrode, Fig. 4a und 4b Einzelheiten zu Fig. 3, vergrößert herausgezeichnet, Fig. 5a eine Einstichelektrode zum Einbringen von leitenden Flüssigkeinen, Fig. Sb eine Einstichelektrode mit erweiterungsfähigen Ballons als Elektroden, Fig. 5 eine kaskadenförmige Anordnung einer Einspritzelektrode (Erzeugung einer "Blume"), Fig. 7 eine kaskadenförmige Einstichelektrode zur Erzeugung von " Fächern ", Fig. 8 und 9 eine Einstichelektrode in zwei Stellungen mit mechanisch einstellbarer Medium-Umlenkung im Körperinnern.1a and 1b show spreading electrodes with umbrella-like spreading, FIG. 2 shows a spreading electrode with a fan-like spreading, FIG. 3 shows a cascade-like one Spreading electrode, FIGS. 4a and 4b, details of FIG. 3, drawn out enlarged, Fig. 5a shows a puncture electrode for introducing conductive liquids, Fig. Sb a puncture electrode with expandable balloons as electrodes, FIG. 5 a cascade arrangement of an injection electrode (creation of a "flower"), 7 shows a cascade-shaped puncture electrode for producing "compartments", Fig. 8 and 9 a puncture electrode in two positions with mechanically adjustable medium deflection inside the body.

Wie die Figuren 1a und 1b in Ansicht und Schnitt zeigen, können die Elektroden E drahtförmige Gebilde sein, welche in einem Rohr 1 gebündelt und z.B. durch Längswände geführt sind. Betätigt und angeschlossen werden sie über eine Stange 2 und Druckknopfmechanismus 3.As FIGS. 1a and 1b show in view and section, the Electrodes E be wire-like structures which are bundled in a tube 1 and e.g. are led through longitudinal walls. They are operated and connected via a rod 2 and push button mechanism 3.

Die Einstichspitze ist mit 4 bezeichnet. Hinter der Spitze 4 sind Umlenkwölbungen 5 eingeformt, die ein Ausfahren der unter Vorspannung stehenden Elektrodendrähte E in Schirmform ermöglichen. Diese Elektrodendrähte E können auch als Röhrchen ausgebildet sein, so daß mit ihnen auch Flüssigkeiten und Gase injiziert werden können.The puncture point is denoted by 4. Behind the top 4 are Deflection curvatures 5 formed, which extend the under tension Allow electrode wires E in shield form. These electrode wires E can also be designed as a tube so that liquids and gases are also injected with them can be.

Bei der Fig. 2 handelt es sich im Prinzip um dasselbe wie bei den Figuren la und lb, nur ist hier das Elektrodenbündel E in Fächerform angeordnet. Der oder die Fächer können auch seitlich angeordnet sein.In Fig. 2 is in principle the same as in the Figures la and lb, only here the electrode bundle E is arranged in a fan shape. The compartment or compartments can also be arranged laterally.

Fig. 3 zeigt eine kaskadenförmige Ausbildung der Elektroden nach Fig. 1. Durch die Hintereinanderschaltung von solchen ausfahrbaren Elektrodenschirmen ist es möglich, im Körperinnern eine sogenannte ~Kaskaden-Ionophorese" herbeizuführen, d.h. bringt man durch den Elektrodenschirm El eine ionisierte Behandlungsflüssigkeit 7 in den Körper ein und legt an den Elektrodenschirm El eine Positivladung und an den Elektrodenschirm E2 eine Negativladung, so werden die Ionen 7 der Behandlungsflüssigkeit durch El in Pfeilrichtung nach vorn gedrückt und durch den Elektrodenschirm E2 in Pfeilrichtung nach vorn gezogen. An gewünschter Stelle können diese ionisierten Flüssigkeiten sogar durch einen entsprechenden Schirm wieder abgesaugt werden.Fig. 3 shows a cascade design of the electrodes according to Fig. 1. By connecting such extendable electrode screens in series is it possible to induce a so-called "cascade ionophoresis" inside the body, i.e., an ionized treatment liquid is brought through the electrode screen El 7 enters the body and applies a positive charge and to the electrode screen El If the electrode screen E2 has a negative charge, the ions 7 of the treatment liquid become pushed forward by El in the direction of the arrow and pushed through the electrode shield E2 in Direction of arrow pulled forward. These can be ionized at the desired point Liquids can even be sucked off again through a suitable screen.

Dies ist von besonderer Wichtigkeit, da man mit dieser Methode ansonsten schädliche Medikamente in den Körper einbringen und weiterreichen und dann wieder abziehen kann. Schließlich kann durch eine computermäßige Schaltung der Elektrodenschirme zwischen den Kaskaden ein Hin- und Herschieben der ionisierten Flüssigkeiten nach Wunsch erreicht werden, Sämtliche bisher beschriebenen Elektroden eignen sich auch zur mechanischen Massage, also Gewebelockerung und Tu mo rzerstörung.This is of particular importance as this method would otherwise Bringing harmful drugs into the body and passing them on and then again can pull off. Finally, through a computerized circuit of the electrode shields between the cascades, the ionized ones move back and forth Liquids can be achieved as desired, All electrodes described so far are also suitable for mechanical massage, i.e. loosening tissue and destroying tumors.

Fig. 4a zeigt eine Arretiermöglichkeit der ausgefahrenen Elektrodenschirme mit Hilfe eines Gewindes 8 und einer Rän delschraube 9.4a shows a possibility of locking the extended electrode shields with the help of a thread 8 and a knurled screw 9.

Fig. 4b zeigt eine in weiten Grenzen einstellbare Möglichkeit der Betätigungsstange 2 gegenüber dem Rohr 1 durch eine seitlich klemmende Rändelschraube 10.Fig. 4b shows a possibility of the adjustable within wide limits Actuating rod 2 opposite the tube 1 by a laterally clamping knurled screw 10.

In den nun folgenden Figuren sind Lösungen beschrieben, bei welchen vorwiegend mit flüssigen oder gasförmigen Medien als Elektrodenmaterial gearbeitet wird.In the figures that now follow, solutions are described in which mainly worked with liquid or gaseous media as electrode material will.

Fig. 5a zeigt eine Nadel 11 mit Spitze 12, die in einem Rohr 13 geführt ist. Zwischen Spitze 12 und Ende des Rohres 13 ist ein durch Verschiebung des Rohres 13 gegenüber der Nadel 11 einstellbarer Ringraum oder Löcher 14, durch welchen oder welche - in Pfeilrichtung gesehen - Elektrodenflüssigkeiten und Gase injiziert werden können.FIG. 5 a shows a needle 11 with a tip 12 which is guided in a tube 13 is. Between the tip 12 and the end of the tube 13 is a displacement of the tube 13 with respect to the needle 11 adjustable annular space or holes 14 through which or which - seen in the direction of the arrow - electrode liquids and gases are injected can.

Eine Abwandlung zur Fig. 5a zeigt die Fig. Sb. Hier werden durch pneumatischen oder hydraulischen Druck Ballone 15 nach dem Einstechen in den Körper ausgefahren und dienen so als Elektroden oder Massagekörper. Diese Ballone 15 können außerdem porös sein und das Elektrodenmedium durchlassen.A modification of FIG. 5a is shown in FIG. 5b. Here, pneumatic or hydraulic pressure balloons 15 deployed after piercing the body and thus serve as electrodes or massage bodies. These balloons 15 can as well be porous and allow the electrode medium to pass through.

Fig. 6 zeigt die kaskadenförmige Anordnung der Elektrode entsprechend Fig. 5a. Es können hier dieselben Behandlungsmethoden, wie unter Fig. 3 beschrieben, Anwendung finden. Es kann z~B. durch einen Schlitz 14 Isolationsmedium und durch den oder die anderen Schlitze leitendes Medium eingespritzt werden. Auch ist es möglich, noch mehrere solcher Düsen 14 hintereinander anzuordnen.Fig. 6 shows the cascade arrangement of the electrode accordingly Figure 5a. The same treatment methods as described under Fig. 3 can be used here, Find application. It can e.g. through a slot 14 Isolation medium and conductive medium is injected through the other slot or slots. Even it is possible to arrange several such nozzles 14 one behind the other.

Schließlich kann auch noch eine Kombination solcher Einstichelektroden mit einem Endoskop stattfinden, wobei z.B. die Endoskopoptik in der Spitze untergebracht ist bzw. die ganze Vorrichtung als Endoskop -auch sondenähnlich - ausgebildet ist.Finally, a combination of such puncture electrodes can also be used take place with an endoscope, e.g. the endoscope optics are housed in the tip is or the entire device is designed as an endoscope - also like a probe - is.

Fig. 7 zeigt eine Einstichelektrode, bei welcher das Elektroden~ medium nur auf einer Seite 16a, 16b austreten kann. Hier wird sich also eine fächerförmige Elektrode herausbilden, während sich bei den Figuren 5 und 6 "blumenartige" Elektroden herausbilden.7 shows a puncture electrode in which the electrode medium can only emerge on one side 16a, 16b. So here will be a fan-shaped Form electrode, while in Figures 5 and 6 "flower-like" electrodes develop.

Fig. 8 und 9 schließlich zeigen noch eine Möglichkeit, die Umlenkung des Elektrodenmediums dadurch zu erhöhen und zu erweitern, indem die innere Nadel als Hohlnadel 20 ausgebildet ist, in welcher ein Betätigungsdraht 21 geführt ist, welcher die elastisch verformbare und rückziehbare Spitze 22 zu verstellen in der Lage ist. Es ist klar, daß sich dadurch die Umlenkweite von w auf W vergrößert.Finally, FIGS. 8 and 9 show another possibility, the deflection The electrode medium is thereby increased and expanded by the inner needle is designed as a hollow needle 20, in which an actuating wire 21 is guided, which the elastically deformable and retractable tip 22 to adjust in the Location is. It is clear that this increases the deflection width from w to w.
