Description

Vorrichtung zur Entfernung von Knochengewebe bei endoskopischen Operationen Device for removing bone tissue during endoscopic operations
Die Erfindung betrifft eine Vorrichtung zum Entfernen von Knochengewebe bei endoskopischen Operationen, mit mindestens einem konzentrisch um eine längliche Sonde angeordne- ten Schneidwerkzeug.The invention relates to a device for removing bone tissue during endoscopic operations, with at least one cutting tool arranged concentrically around an elongated probe.
Die Erfindung ist besonders nützlich bei der Durchführung von endoskopischen Operationen für die Behandlung von Bandscheibenvorfällen, wobei die Erfindung nicht unbedingt auf diesen Zweck beschränkt ist.The invention is particularly useful in the performance of endoscopic surgeries for the treatment of herniated discs, although the invention is not necessarily limited to this purpose.
Endoskopische Techniken und Vorrichtungen zur Behandlung von Bandscheibenvorfällen in der Wirbelsäule sind hinreichend bekannt. Bei solchen Operationen wird nach Einschnei- den der Haut des Patienten zunächst ein erstes längliches Element mit einer stumpfen konischen Spitze eingeführt, um weiches Gewebe bis in die Nähe der beschädigten, zu behandelnden Bandscheibe anzupassen. Nach Einführung dieses ersten länglichen Elements, wird - über dieses - eine feine Kanüle eingeführt, deren Innendurchmesser dem Außendurchmesser des ersten länglichen Elements entspricht. Der Au- ßendurchmesser dieser Kanüle kann zwischen 2 und 10 mm betragen, wobei es am üblichsten ist, dass die Kanülen einen Außendurchmesser von 6 mm aufweisen. Die Kanüle ist stumpf und kann an ihrem distalen Ende verschiedene Geomet- rien aufweisen, wobei die eine distale Kante im Allgemeinen im Wesentlichen schräg zur Achse der Kanüle verläuft, um eine bessere Sicht auf den Arbeitsbereich zu ermöglichen. Nach der Einführung der Kanüle wird das erste längliche Element herausgezogen, wobei ein offener Zugangskanal zum Bereich der beschädigten Bandscheibe geöffnet bleibt, in den eine optische Sonde eingeführt wird, die genau in diesen Kanal passt und ihrerseits Kanäle für unter Druck stehendes Wasser zur Reinigung/Absaugung von Elementen und bei einigen Modellen auch Arbeitskanäle für verschiedene Geräte zur Behandlung oder Handhabung des Gewebes aufweist.Endoscopic techniques and devices for treating disc herniations in the spine are well known. In such operations, after cutting the patient's skin, a first elongated member having a blunt conical tip is first inserted to accommodate soft tissue close to the damaged disc to be treated. After introduction of this first elongated element, a fine cannula is inserted over this, the inner diameter of which corresponds to the outer diameter of the first elongate element. The Au The diameter of this cannula may be between 2 and 10 mm, the most common being that the cannulas have an outside diameter of 6 mm. The cannula is blunt and may have various geometries at its distal end, with one distal edge generally generally oblique to the axis of the cannula, for better visibility of the working area. Upon insertion of the cannula, the first elongate member is withdrawn leaving an open access channel open to the area of the damaged disc into which an optical probe is inserted which fits snugly into this channel and, in turn, channels of pressurized water for cleaning / aspiration of elements and, in some models, also working channels for various devices for treating or handling the tissue.
Es kommt jedoch zu einem Problem, wenn ein Bereich mit Knochenwachstum oder Fehlbildungen des Knochens vorliegt, der den Bereich der Bandscheibe von der Spitze der Kanüle trennt oder der in diesem Arbeitsbereich stört. Bei einigen dieser Fälle, die tatsächlich häufig zu finden sind, ist es erforderlich, ein Schneidwerkzeug zu benutzen, um den Knochen abzuschneiden oder abzufeilen, um so Zugang zu dem zu behandelnden Bereich zu erlangen.However, there is a problem when there is an area of bone growth or malformation of the bone that separates the area of the disc from the tip of the cannula or interferes with that area of work. In some of these cases, which are in fact frequent, it is necessary to use a cutting tool to cut or file off the bone so as to gain access to the area to be treated.
In diesen Fällen bieten die bisher bekannten Techniken drei mögliche Lösungen. Die erste besteht in einem Schneidwerkzeug, das so bemessen ist, dass es in einen Arbeitskanal der optischen Sonde eingeführt werden kann. Diese Lösung ermöglicht es dem Benutzer, Knochengewebe abzuschneiden und dabei eine Sichtkontrolle seiner Operationen aufrechtzuerhalten. Hier besteht jedoch das Problem, dass das Werkzeug notwendigerweise einen sehr kleinen Durchmesser aufweisen muss (einen Durchmesser von maximal 1,5 mm) und dass die Operationen zur Entfernung des Knochengewebes zu lange dauern können, was letztendlich sogar zu einem Schaden für den Patienten führen kann. Eine zweite bekannte Lösung besteht darin, die optische Sonde herauszuziehen, und anstatt dieser ein Schneidwerkzeug mit einem größeren Durchmesser zu benutzen. Hier liegt das Problem vor, dass der Benutzer dazu gezwungen ist, die Operationen ohne eine direkte Sicht auf die vorliegenden weichen Gewebe durchzuführen, mit der damit einhergehenden Gefahr, das zu dem Epiduralraum gehörige Nervengewebe zu beschädigen.In these cases, the previously known techniques offer three possible solutions. The first is a cutting tool that is sized to be inserted into a working channel of the optical probe. This solution allows the user to cut bone tissue while maintaining visual control of its operations. Here, however, there is the problem that the tool necessarily has a very small diameter must be (a maximum of 1.5 mm in diameter) and that the operations to remove the bone tissue may take too long, which ultimately may even lead to harm to the patient. A second known solution is to pull out the optical probe, and instead use a larger diameter cutting tool. Here, the problem is that the user is forced to perform the operations without a direct view of the soft tissues present, with the concomitant danger of damaging the nerve tissue associated with the epidural space.
Gemäß der bekannten Technik, ist das Schneidwerkzeug gewöhnlich ein Zylinder, dessen distales Ende senkrecht zur Zylinderachse verläuft. Das genannte distale Ende besteht aus einem im Allgemeinen sägeförmigen Schneidbereich, wobei sich der Durchmesser des Werkzeugs für jede der beiden genannten Lösungsmöglichkeiten wesentlich ändert.According to the known technique, the cutting tool is usually a cylinder whose distal end is perpendicular to the cylinder axis. Said distal end consists of a generally saw-shaped cutting area, the diameter of the tool substantially changing for each of the two possible solutions.
Die Erfindung beinhaltet eine Vorrichtung zum Entfernen von Knochengewebe bei endoskopischen Operationen, mit mindestens einem konzentrisch um eine längliche Sonde angeordneten Schneidwerkzeug, bei dem das Schneidwerkzeug einen distalen Schneidbereich mit einer konischen Geometrie auf- weist, wobei die distale konische Fläche seitliche Schneidkanten aufweist. Die Schneidkanten können zum rechts- und/oder linksseitigen Schneiden ausgebildet sein.The invention includes an apparatus for removing bone tissue in endoscopic operations, comprising at least one cutting tool concentrically disposed about an elongated probe, wherein the cutting tool comprises a distal cutting portion having a conical geometry, the distal tapered surface having lateral cutting edges. The cutting edges may be formed for right- and / or left-side cutting.
Die neue Vorrichtung weist gegenüber den vorbekannten Vor- richtungen im Wesentlichen zwei Vorteile auf. Zunächst ermöglicht der konische Schneidbereich einen fortschreitenden Schnitt des zu entfernenden Bereichs. Außerdem, da hier eine seitliche Schneidkante vorliegt (zum Schneiden auf der linken und auf der rechten Seite) , wird eine einwandfreie Steuerung des Schnitts des Werkzeugs erreicht, das nur dann schneidet, wenn das Werkzeug in die Richtung gedreht wird, in die der Schnitt bewirkt wird. Auf diese Weise kann im Vergleich zu den vorbekannten Möglichkeiten sowohl dieThe new device has essentially two advantages over the previously known devices. First, the tapered cutting area allows a progressive cut of the area to be removed. In addition, since there is a lateral cutting edge (for cutting on the left and right), proper control of the cut of the tool is achieved, which cuts only when the tool is rotated in the direction in which the cut is made. In this way, in comparison to the previously known possibilities, both the
Schneidfähigkeit als auch gleichzeitig die Sicherheit erhöht werden.Cutting ability and safety at the same time can be increased.
Um das Risiko einer unerwünschten Beschädigung des Gewebes zu verringern, ist der konische distale Bereich an derTo reduce the risk of undesired damage to the tissue, the conical distal region is at the
Spitze oder an dem am weitesten distal liegenden Teil abgerundet.Pointed or rounded at the distal part.
In bevorzugten Ausführungen verlaufen die Schneidkanten des Schneidwerkzeugs parallel zueinander, und es ist noch bevorzugter, dass sie schraubenförmig auf der konischen Fläche verlaufen, unter Freilassung von Rillen für die Aufnahme des entfernten Gewebes.In preferred embodiments, the cutting edges of the cutting tool are parallel to each other, and more preferably, they extend helically on the conical surface, leaving grooves for receiving the removed tissue.
Obwohl die Vorrichtung in einer einfacheren Ausführung aus einer Sonde und einem Schneidwerkzeug besteht, so kann sie doch mit weiteren an sich bekannten Vorrichtungen ergänzt werden. Die Vorrichtung kann weiterhin mehr als ein Schneidwerkzeug mit den zuvor beschriebenen Merkmalen auf- weisen. Genauer gesagt, kann die Vorrichtung ein zweitesAlthough the device in a simpler embodiment consists of a probe and a cutting tool, yet it can be supplemented with other devices known per se. The device can furthermore have more than one cutting tool with the features described above. More precisely, the device can be a second
Schneidwerkzeug mit einem größeren Durchmesser als das erste Schneidwerkzeug aufweisen. In diesem Fall ist die Konizität des ersten Schneidwerkzeugs vorzugsweise geringer als die Konizität des zweiten. Das heißt, die konische Fläche des ersten Werkzeugs weist zur unteren Mittelachse einen kleineren Winkel auf als die des zweiten Werkzeugs. Durch diese Anordnung erhält man Schneidbereiche, die fortschreitend größer werden, ohne dass hierzu das Fortschreiten des entfernten Bereichs zu sehr erhöht werden müsste.Having cutting tool with a larger diameter than the first cutting tool. In this case, the taper of the first cutting tool is preferably less than the taper of the second. That is, the conical surface of the first tool has a smaller angle to the lower central axis than that of the second tool. By this arrangement, cutting areas are obtained, which are progressively larger without the progression of the would have to be increased too much.

Die Figuren 1 bis 10 zeigen eine mögliche Ausführung der Vorrichtung nach der vorliegenden Erfindung, die lediglich schematisch dargestellt ist, wobei hier auf die wichtigsten Teile Bezug genommen wird.Figures 1 to 10 show a possible embodiment of the device according to the present invention, which is shown only schematically, with reference to the most important parts.
Andere Elemente der Vorrichtung können nach in diesem Be- reich hinreichend bekannten Techniken ausgeführt sein. Beispielhaft wird hierzu ausdrücklich auf das Patent ES 2279733 (WO 2008/064842) des gleichen Erfinders verwiesen.Other elements of the device may be designed according to techniques well known in the art. For example, reference is expressly made to the patent ES 2279733 (WO 2008/064842) of the same inventor.
Die erfindungsgemäße Vorrichtung weist im dargestellten Ausführungsbeispiel aus eine Sonde 1, die zumindest einen Kanal 11 aufweist, zum Beispiel einen Führungskanal 11 und/oder einen Infiltrationskanal 111, oder beides, und ein erstes und ein zweites Schneidwerkzeug 2, 3, die konzentrisch um die Sonde 1 angeordnet sind. Jedes Schneidwerk- zeug 2, 3 verfügt über ein distales Ende 21, 31, das konisch bzw. kegelstumpfförmig ausgebildet ist und über eine innere Öffnung 23, die bei der Benutzung die Sonde 1 umgibt.In the exemplary embodiment shown, the device according to the invention comprises a probe 1 which has at least one channel 11, for example a guide channel 11 and / or an infiltration channel 111, or both, and a first and a second cutting tool 2, 3 which are concentric around the probe 1 are arranged. Each cutting tool 2, 3 has a distal end 21, 31, which is conical or frusto-conical in shape and has an inner opening 23, which surrounds the probe 1 in use.
Die konischen Bereiche 21, 31, 33 weisen zahlreiche Schneiden auf, die parallel zueinander und schraubenförmig verlaufen. Die Geometrie der Schneiden (Anstellwinkel, Schneide und Eintritt) sind so, dass ein seitliches Schneiden er- folgt (Schnitt nach links oder Schnitt nach rechts) , gemäß Techniken, die aus dem Bereich industrieller Fräsen bekannt sind. Auf diese Weise führt das Werkzeug nur dann einen Schnitt aus, wenn es in eine bestimmte Richtung gedreht wird.The conical regions 21, 31, 33 have numerous cutting edges, which run parallel to each other and helically. The geometry of the cutting edges (angle of attack, cutting edge and entry) are such that lateral cutting takes place. follows (cut to the left or cut to the right) according to techniques known in the field of industrial milling. In this way, the tool cuts only when it is rotated in a certain direction.
Wie aus den Figuren zu sehen ist, weist das zweite Schneidwerkzeug 3 einen größeren Außendurchmesser sowie auch eine größere Konizität auf. Der am weitesten distal liegende Punkt 22, 32 der Schneidwerkzeuge 2, 3 ist abgerundet. Bei der Benutzung wird zunächst das erste Schneidwerkzeug 2 eingeführt, das dabei linear entlang der Sonde gleitet, ohne dass eine Drehung in die Schnittrichtung des Schneidwerkzeugs erfolgt. Die konische Form begünstigt das Ein- dringen ohne Beschädigung der weichen Gewebe. Nach Auftreffen auf das zu entfernende Knochengewebe, wird das Werkzeug in die Schnittrichtung gedreht.As can be seen from the figures, the second cutting tool 3 has a larger outer diameter and also a greater conicity. The furthest distal point 22, 32 of the cutting tools 2, 3 is rounded. In use, first the first cutting tool 2 is introduced, which thereby slides linearly along the probe, without any rotation in the cutting direction of the cutting tool. The conical shape promotes penetration without damaging the soft tissue. After hitting the bone tissue to be removed, the tool is rotated in the cutting direction.
Wenn der zu entfernende Bereich größer ist, so wird ein zweites Schneidwerkzeug 3 mit einem größeren Durchmesser eingeführt, und so fortlaufend, falls noch größere Bereiche entfernt werden müssen. Obwohl die Erfindung im Hinblick auf bevorzugte Ausführungsbeispiele beschrieben wurde, so sind diese jedoch nicht als eine Einschränkung der Erfin- düng zu verstehen, die durch die jeweils weitreichendste Auslegung der folgenden Patentansprüche festgelegt wird. If the area to be removed is larger, then a second cutting tool 3 with a larger diameter is inserted, and so on, if even larger areas need to be removed. Although the invention has been described in terms of preferred embodiments, they are not to be construed as a limitation of the invention, which is determined by the most extensive interpretation of the following claims.
