Abstract

The anal probe has a shaft and more than one electrode on each side of the shaft with separate cables leading to a measurement device or stimulator. There are at least three electrodes on one side of the shaft.

Description

Zur Messung der Funktionsfähigkeit des menschlichen Schließ­ muskels sowie zur Stimulation der Muskeltätigkeiten werden in der Medizintechnik Analsonden eingesetzt. Analsonden bestehen aus einem Schaft, an dessen Manteloberfläche Elektroden ange­ ordnet sind. Dieser Schaft wird in den Analkanal eingeführt. Die Elektroden messen die Muskelströme des Schließmuskels bzw. geben elektrische Impulse an den Schließmuskel ab.To measure the functionality of the human locking system muscles as well as for the stimulation of muscle activities are in of medical technology used anal probes. Anal probes exist from a shaft with electrodes on its surface are arranged. This shaft is inserted into the anal canal. The electrodes measure the muscle currents of the sphincter or give electrical impulses to the sphincter.

Stand der Technik sind einmal "monopolare" Sonden mit nur einer Elektrode. Die Anode ist am Schaft der Analsonde und die Kathode wird an anderen Körperpartien, insbesondere Rücken und Becken, angelegt, oder umgekehrt. Monopolare Sonden wer­ den in erster Linie nicht zu Meßzwecken eingesetzt sondern zu Stimulationszwecken.State of the art are "monopolar" probes with only an electrode. The anode is on the shaft of the anal probe and the cathode is on other parts of the body, especially the back and basin, created, or vice versa. Monopolar probes which are not primarily used for measuring purposes but for stimulation purposes.

Stand der Technik sind weiter "bipolare" Sonden, die zu beiden Zwecken eingesetzt werden können. Anode und Kathode befinden sich am Schaft. Entweder sind sie als Ringe ausgebildet, die den Schaft umschließen oder ihre Anordnung ist "zirkulär", also in schaftumlaufender Reihe.The state of the art further includes "bipolar" probes, which go to both Can be used for purposes. Anode and cathode are located on the shaft. Either they are designed as rings that the Enclose the shaft or its arrangement is "circular", ie in circumferential series.

Stand der Technik sind schließlich weiter "tripolare" Aus­ führungen mit drei Elektroden, die allerdings funktionell zur bipolaren Ausführung keine grundsätzlichen Unterschiede auf­ weisen.State of the art are finally "tripolar" off guides with three electrodes, which, however, functionally bipolar design no fundamental differences point.

Sämtlichen Ausführungen nach dem Stand der Technik ist es ge­ meinsam, daß auch dann, wenn mehrere Elektroden am Schaft sind, diese mit dem Meßgerät bzw. dem Impulsgeber nicht jeweils ein­ zeln verkabelt sind sondern in der Weise, daß auch von mehreren Elektroden immer nur ein Meßwert zum Meßgerät gegeben wird und umgekehrt vom Impulsgeber immer nur ein Impuls an alle Elektro­ den. Mit diesem Stand der Technik bleibt eine anatomische Be­ sonderheit des Schließmuskels unberücksichtigt und kann des­ halb meßtechnisch auch nicht erfaßt werden:All designs according to the prior art are ge together that even if there are several electrodes on the shaft,  not each one with the measuring device or the pulse generator are wired but in such a way that even several Electrodes are only ever given a measured value to the measuring device and conversely, only one impulse from the pulse generator to all electrical systems the. With this state of the art, an anatomical loading remains peculiarity of the sphincter disregarded and can semi-metrological also not be recorded:

Der gewöhnliche Muskel wird von der Muskelmitte her innerviert, das heißt: In der Muskelmitte werden über einen Nerv Muskel­ fasern elektrisch erregt. Die elektrischen Potentiale fließen von der Muskelmitte her nach außen zu den Sehnen ab.The ordinary muscle is innervated from the middle of the muscle, That means: in the middle of the muscle, a nerve becomes muscle fibers electrically excited. The electrical potentials flow from the middle of the muscle outwards to the tendons.

Der menschliche Schließmuskel ist grundsätzlich anders aufge­ baut. Es ist ein Ringmuskel, der keine Muskelmitte aufweist, die sich dann zu den Sehnen hin verjüngt. Er hat keinen Anfang und kein Ende. Dennoch wird er prinzipiell in gleicher Weise innerviert wie die übrigen menschlichen Muskeln.The human sphincter is fundamentally different builds. It's a sphincter muscle that has no muscle center, which then tapers towards the tendons. It has no beginning and no end. Nevertheless, in principle it becomes the same innervated like the rest of the human muscles.

Dies mit der Besonderheit, daß der Ringmuskel so behandelt wird, als handle es sich um ein Muskelpaar. Die Innervierung erfolgt somit paarweise, das heißt sowohl von der rechten als auch von der linken Seite aus.This with the peculiarity that the sphincter is treated in this way becomes like a pair of muscles. The innervation thus takes place in pairs, i.e. both from the right as well as from the left side.

Bei pathologischen Zuständen ist es von diagnostischer Bedeu­ tung, diese beiden Muskelbereiche gesondert zu erfassen. Mit herkömmlichen Analsonden ist dies aus zwei Gründen nicht mög­ lich. Einmal ist die Anzahl der Elektroden darauf nicht aus­ gelegt. Zum anderen fehlt die einzelne Verkabelung der Elek­ troden, die es erst ermöglicht, die beiden Hälften des Schließ­ muskels meßtechnisch gesondert anzusprechen. In the case of pathological conditions, it is of diagnostic importance ting to capture these two muscle areas separately. With This is not possible with conventional anal probes for two reasons Lich. First, the number of electrodes on it is not placed. On the other hand, the individual wiring of the Elek is missing tread, which makes it possible to lock the two halves to address muskels separately.  

Dies ermöglicht die erfinderische Sonde nach Anspruch 1: An jeder Seite des Schaftes ist mindestens ein Elektrodenpaar angeordnet, wobei jede der Elektroden eine gesonderte elek­ trische Leitung zum Meßgerät aufweist. Diese paarige Anord­ nung und die gesonderte Verbindung zwischen Elektrode und Meßgerät ermöglicht die gesonderte Auswertung der elektrischen Impulse, die an der jeweiligen Muskelhälfte des Schließmuskels gemessen werden bzw. deren gesonderte Stimulation.This enables the inventive probe according to claim 1: On There is at least one pair of electrodes on each side of the shaft arranged, each of the electrodes having a separate elec has trical line to the measuring device. This paired arrangement voltage and the separate connection between the electrode and Measuring device enables the separate evaluation of the electrical Impulses on the respective muscle half of the sphincter are measured or their separate stimulation.

Unabhängig von der anatomischen Besonderheit des Schließmuskels sind herkömmliche Sonden noch aus einem weiteren Grund unzu­ länglich: Mit den wenigen Elektroden, die sie aufweisen, können sie lediglich Impulse als solche messen, nicht aber deren Fluß entlang der Muskelfasern. Dies wird erst damit ermöglicht, daß jeweils mehr als zwei Elektroden an jeder Seite des Schaf­ tes sind, die jeweils wieder einzeln mit dem Meßgerät verkabelt sind. Dies wird mit Anspruch 2 beansprucht.Regardless of the anatomical peculiarity of the sphincter conventional probes are unavailable for another reason oblong: with the few electrodes they can have they only measure impulses as such, but not theirs Flow along the muscle fibers. This is only possible with that more than two electrodes on each side of the sheep tes are, each individually wired back to the measuring device are. This is claimed in claim 2.
