Aus
der
Des Weiteren ist eine Sonde zur Erzeugung einer elektrohydraulischen Druckwelle zum Einwirken auf ein Objekt bekannt, bei der zwei Elektroden in einer Sondenhülse geführt sind. Eine Elektrode ist an einen Pluspol und die andere Elektrode an einen Minuspol angeschlossen. Bei Ansteuerung dieser Elektroden folgt ebenfalls eine Funkenentladung, wobei zum gleichmäßigen Abbrand der Elektroden erforderlich ist, dass ein Wechsel in der Polung der Elektroden stattfindet, da ansonsten ein ungleichmäßiger Abbrand stattfindet und die Sondenhülse einseitig einen Hülsenabbrand aufweisen kann, der zu einer geschlitzten Sondenhülse führt. Ein vorzeitiger Austausch einer solchen Sonde wird erforderlich.Of Further, a probe for generating an electro-hydraulic Pressure wave for acting on an object known in which two electrodes in a probe sleeve guided are. One electrode is connected to a positive pole and the other electrode connected to a negative pole. When controlling these electrodes also follows a spark discharge, whereby the uniform burnup the electrodes required is a change in polarity the electrodes takes place, since otherwise an uneven burnup takes place and the probe sleeve on one side a tube burn can lead, which leads to a slotted probe sleeve. One premature replacement of such a probe is required.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Sonde zur Erzeugung einer elektrohydraulischen Druckwelle zum Einwirken auf ein Objekt zu schaffen, die eine hohe Lebensdauer und einen gleichmäßigen Abbrand der Elektroden ermöglicht.Of the The invention is therefore based on the object, a probe for generating an electro-hydraulic pressure wave for acting on an object create a long life and a uniform burnup allows the electrodes.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Durch die Ausgestaltung einer ersten Elektrode, die einen stabförmigen Abschnitt aufweist, der dem proximalen Ende einer Sondenhülse zugeordnet ist und zumindest einer zweiten Elektrode, welche einen wendelförmigen Abschnitt aufweist, welcher die erste Elektrode umgibt, wird ermöglicht, dass bei einer Funkenentladung der Funke reihum zum stabförmigen Abschnitt der ersten Elektrode entlang dem wendelförmigen Abschnitt der zumindest einen zweiten Elektrode verläuft. Dadurch wird ein einseitiger Hülsenabbrand der Sondenhülse verhindert. Dadurch wird während dem Betrieb der Sonde eine gleichbleibende Qualität der Funkenbildung sichergestellt. Die Lage des Funken bleibt dem Grunde nach gleich. Gleichzeitig wird ermöglicht, dass die elektrohydraulische Druckwelle durch Funkenentladung zwischen den beiden Elektrodenenden bewirkt wird, ohne dass eine Funkenentladung in Richtung auf die Sondenhülse stattfindet.By the embodiment of a first electrode, the rod-shaped portion which is associated with the proximal end of a probe sleeve and at least a second electrode having a helical section, which surrounds the first electrode, allows for a spark discharge the spark in turn to the rod-shaped Section of the first electrode along the helical section the at least one second electrode extends. This will be a one-sided Hülsenabbrand the probe sleeve prevented. This will be during the operation of the probe a consistent quality of sparking ensured. The location of the spark remains basically the same. At the same time it is possible that the electro-hydraulic pressure wave by spark discharge between the two electrode ends is effected without a spark discharge towards the probe sleeve takes place.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, das während der Erzeugung der elektrohydraulischen Druckwelle die stabförmige Elektrode an einem Minuspol (Kathode) und die zumindest eine Elektrode mit wendelförmigem Abschnitt an einem Pluspol (Anode) vorgesehen ist. Dadurch sind einfache Verhältnisse für den Gebrauch der Sonde gegeben.To an advantageous embodiment of the invention is provided that while the generation of the electro-hydraulic pressure wave, the rod-shaped electrode at a negative pole (cathode) and the at least one electrode with helical section is provided at a positive pole (anode). These are simple conditions for the Use of the probe given.
Bevorzugt ist vorgesehen, dass die Erzeugung der elektrohydraulischen Druckwelle ohne Wechsel der Polung der Elektroden vorgenommen wird. Dadurch ist eine einfache Ansteuerung ermöglicht.Prefers is provided that the generation of the electro-hydraulic pressure wave without changing the polarity of the electrodes is made. Thereby is a simple control allows.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die erste Elektrode, die sich stabförmig innerhalb der Sondenhülse, vorzugsweise entlang deren Längsachse erstreckt, bis zum proximalen Ende der Sondenhülse eine Isolierung aufweist und die zumindest eine zweite Elektrode einen nicht isolierten wendelförmigen Abschnitt umfasst. Dadurch wird eine elektrische Kontaktierung zwischen dem wendelförmigen Abschnitt und dem stabförmigen Abschnitt der ersten Elektrode innerhalb der Sondenhülse vermieden, so dass nur am äußeren Endabschnitt der Sondenhülse das freie Ende der stabförmigen Elektrode und das der zumindest einen weiteren Elektrode mit wendelförmigem Abschnitt zur Funkenentladung vorgesehen sind.A Further advantageous embodiment of the invention provides that the first electrode extending rod-like within the probe sleeve, preferably along its longitudinal axis extends until it has insulation to the proximal end of the probe sleeve and the at least one second electrode comprises a non-insulated helical section includes. As a result, an electrical contact between the helical Section and the rod-shaped Section of the first electrode within the probe sleeve avoided, leaving only at the outer end section the probe sleeve the free end of the rod-shaped Electrode and the at least one further electrode with helical section are provided for spark discharge.
Die zumindest eine zweite Elektrode ist im Anschluss an den wendelförmigen Abschnitt ebenfalls isoliert ausgebildet. Dadurch können sowohl die stabförmige Elektrode als auch die zumindest eine zweite Elektrode gegeneinander isoliert bis zu deren Anschlussstellen geführt werden. Gleichzeitig ist dadurch eine Verschleißanzeige gegeben, da nach dem Abbrand des nicht isolierten, wendelförmigen Abschnitts eine weitere Funkenbildung verhindert ist.The at least one second electrode is adjacent to the helical section also formed isolated. This allows both the rod-shaped electrode as well as the at least one second electrode isolated from each other are led to their connection points. At the same time thereby a wear indicator given since after burning off the uninsulated, helical section a further sparking is prevented.
Die erste Elektrode ist bevorzugt im Durchmesser gleich zur zumindest einen weiteren Elektrode ausgebildet. Dadurch wird ermöglicht, dass die Elektroden aus einem gleichen Ausgangsmaterial hergestellt werden können, wodurch sich die Herstellungskosten reduzieren.The first electrode is preferably equal in diameter to at least formed a further electrode. This will allow that the electrodes are made of a same starting material can be whereby the manufacturing costs are reduced.
Nach einer alternativen vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die erste Elektrode, die vorzugsweise als Kathode ausgebildet ist, bevorzugt im Durchmesser größer als die zumindest eine weitere Elektrode ausgebildet ist. Diese Ausführungsform kann ermöglichen, dass für die stabförmige Elektrode ein anderes elektrisch leitendes Material als für die wendelförmig ausgebildete Elektrode verwendet wird. Dadurch kann wiederum ein gleichmäßiger Abbrand erzielt werden. Darüber hinaus kann ein unterschiedlicher Durchmesser den Vorteil aufweisen, dass eine geringere Baugröße erzielt wird. Des Weiteren kann alternativ vorgesehen sein, dass bei einer Polung, bei der die stabförmige Elektrode auf Plus liegt und die wendelförmige Elektrode auf Minus liegt, die stabförmige Elektrode im Durchmesser größer als die wendelförmig ausgebildete Elektrode ausgebildet wird, um wiederum einen gleichmäßigen Abbrand zu erzielen. Dies beruht darauf, dass der Verschleiß an der Anode beziehungsweise an der stabförmigen Elektrode durch emittierende Ionen größer als bei der Kathode, also dem wendelförmigen Abschnitt, ist.To an alternative advantageous embodiment of the invention provided that the first electrode, preferably as a cathode is formed, preferably larger in diameter than the at least one further electrode is formed. This embodiment may allow that for the rod-shaped Electrode another electrically conductive material than for the helically shaped electrode is used. This in turn can be a uniform burnup be achieved. Furthermore a different diameter may have the advantage that achieved a smaller size becomes. Furthermore, it may alternatively be provided that in a Polarity at which the rod-shaped electrode lies on plus and the helical one Electrode is on minus, the rod-shaped electrode in diameter greater than the helical trained electrode is formed, in turn, a uniform burnup to achieve. This is due to the fact that the wear on the Anode or at the rod-shaped electrode by emitting Ions larger than at the cathode, so the helical section is.
Die zumindest eine weitere Elektrode mit wendelförmigem Abschnitt weist bevorzugt eine Steigung auf, die sich in einem Winkelbereich von zumindest 90° erstreckt und den stabförmigen Abschnitt der ersten Elektrode umgibt. Bevorzugt sind 1 bis 10 Windungen vorgesehen, die den wendelförmigen Abschnitt der zumindest einen weiteren Elektrode bilden. Die Anzahl der Windungen zusammen mit der Abbrandgeschwindigkeit der Elektroden bestimmt die Lebensdauer und die Anzahl der Einsätze einer solchen Sonde.The at least one further electrode with a helical section is preferred a slope that extends in an angular range of at least Extends 90 ° and the rod-shaped Surrounds the section of the first electrode. Preference is given to 1 to 10 turns provided that the helical Form section of at least one further electrode. The number the turns together with the burning rate of the electrodes determines the life and the number of uses of such a probe.
Die Steigung der Windungen zur Ausgestaltung des wendelförmigen Abschnitts der zumindest einen weiteren Elektrode ist bevorzugt auf die Abbrandrate der zumindest einen zweiten Elektrode im Vergleich zur ersten Elektrode angepasst. Die zumindest eine zweite Elektrode liegt auf Plus und stellt also die Anode dar, während die zentrale stabförmige Elektrode auf Minus liegt und die Kathode darstellt. Während der Funkenentladung werden Ionen von der Anode emittiert. Dies führt zu einem Verschleiß der Anode, welcher größer ist als derjenige der Kathode. Durch die wendelförmige Anordnung der zumindest einen Elektrode beziehungsweise Anode, insbesondere deren Steigung, wird ermöglicht, dass in Bezug auf die Lage der einander gegenüberliegenden Enden eine gleiche Abbrandrate erzielt wird, so dass die Lage des Funkens dem Grunde nach gleich bleibt. Eine unterschiedliche Abbrandrate zwischen den Elektroden wird dadurch kompensiert. Dadurch kann die Qualität der Funkenbildung erhöht sein.The Slope of the windings for the design of the helical section the at least one further electrode is preferably based on the burning rate the at least one second electrode compared to the first electrode customized. The at least one second electrode is on plus and represents the anode, while the central rod-shaped electrode lies on minus and represents the cathode. During the spark discharge will be Ions emitted from the anode. This leads to a wear of the anode, which is larger as the one of the cathode. Due to the helical arrangement of at least an electrode or anode, in particular their slope, is enabled that in relation to the position of the opposite ends an equal Burn rate is achieved, so the location of the spark the reason stays the same. A different burning rate between the Electrodes are compensated. This can reduce the quality of sparking elevated be.
Die Sondenhülse ist bevorzugt als Metallhülse ausgebildet. Dies ermöglicht eine Dekontamination nach einem Einsatz.The probe sleeve is preferred as a metal sleeve educated. this makes possible a decontamination after use.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der wendelförmige Abschnitt der zumindest einen zweiten Elektrode und der stabförmige Abschnitt der ersten Elektrode in einem Fixiermaterial, insbesondere einem Klebemittel, in der Sondenhülse vorgesehen sind. Diese Ausgestaltung weist den Vorteil auf, dass eine einfache Reinigung ermöglicht ist. Des Weiteren kann dadurch eine Vorfixierung des Abstandes zwischen dem wendelförmigen Abschnitt der weiteren Elektrode zum stabförmigen Abschnitt der Elektrode ermöglicht werden, so dass gleiche Arbeitsbedingungen unabhängig des bereits erfolgten Abbrandes der Elektroden ermöglicht sind. Das Fixiermaterial bildet sich in Analogie des Abbrandes der Elektroden zurück und verbleibt im Wesentlichen bis zum jeweiligen freien Ende der Elektroden.To a further advantageous embodiment of the invention is provided that the helical one Section of the at least one second electrode and the rod-shaped portion the first electrode in a fixing material, in particular an adhesive, in the probe sleeve are provided. This embodiment has the advantage that allows easy cleaning is. Furthermore, this can be a prefixing of the distance between the helical one Section of the further electrode to the rod-shaped section of the electrode, so that equal working conditions are independent of those already done Burning the electrodes allows are. The fixing material is formed in analogy to the burning of the Electrodes back and remains substantially to the respective free end of the Electrodes.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Elektroden als Kupferleiter ausgebildet sind. Dieses Material eignet sich besonders für die Funkenentladung.To a further advantageous embodiment of the invention is provided that the electrodes are formed as copper conductors. This material is suitable especially for the spark discharge.
Des Weiteren ist bevorzugt vorgesehen, dass die Sonde einen Außendurchmesser von weniger als 5 mm, bevorzugt 1 bis 2 mm, aufweist. Trotz der wendelförmigen Anordnung kann ein sehr kleiner Sondendurchmesser erzielt werden, wodurch eine Vielzahl von Einsatzmöglichkeiten gegeben ist.Of Furthermore, it is preferably provided that the probe has an outer diameter of less than 5 mm, preferably 1 to 2 mm. Despite the helical Arrangement, a very small probe diameter can be achieved, whereby a variety of uses is given.
Eine Vorrichtung zur Aufnahme der Sonde ist bevorzugt als Handgerät zur Zertrümmerung von Körperkonkrementen ausgebildet. Solche sogenannten Lithotripter werden beispielsweise zur Zertrümmerung von Harn- und Blasensteinen eingesetzt.A Device for receiving the probe is preferred as a handheld device for fragmentation of body stones educated. Such so-called lithotripters, for example to smash used by urinary and bladder stones.
