Description
Schiebt man nun eine Nadel durch die Führungshülse und bohrt diese Nadel durch den Knochen, bis sie auf die Spitze des Markierstiftes trifft, so entsteht eine Vorbohrung, deren Öffnungen exakt die gewünschte Lage haben, so daß mittels eines üblichen, auf dieser Nadel geführten chirurgischen Bohrwerkzeuges die endgültige Bohrung hergestellt wenden kann, durch die dann der Kreuzband-Ersatz gezogen und am Knochen befestigt wird. If you push a needle through the guide sleeve and drill it This creates a needle through the bone until it hits the tip of the marker pen a pilot hole, the openings of which have exactly the desired position, so that by means of of a conventional surgical drilling tool guided on this needle is the final one Hole made can turn through which then the Cruciate ligament replacement pulled and attached to the bone.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf die schematischc Zeichnung näher erläutert, deren einzige Figur eine Draufsicht auf eine Vorrichtung zur Positionierung eines chirurgischen Bohrwerkzeuges bei Kreuzband-Operationen am Kniegelenk zeigt. The invention is illustrated below using an exemplary embodiment explained in more detail with reference to the schematischc drawing, the only figure a plan view of a device for positioning a surgical drilling tool shows during cruciate ligament operations on the knee joint.
Die allgemein durch das Bezugszeichen 10 angedeutexte Vorrichtung weist eine kreisbogenförmige l-lalterung 12 auf, die aus einem zu einem Teilring gebogenen Streifen aus Edelstahl hergestellt ist. Diese kreisbogen ft>rmige lhalterung 12 ist mit mehreren, radial verlaufenden Bohrungen 12a, 12b, 12c... I2iversehen, also Bohrungen, die zum Mittelpunkt des Kreises dieses Kreisbogens hin gerichtet sind. The device indicated generally by the reference number 10 has an arc-shaped l-aging 12, which consists of a partial ring curved strip is made of stainless steel. This circular arc ft> shaped oil holder 12 is provided with several, radially extending bores 12a, 12b, 12c ... that is, holes that are directed towards the center of the circle of this arc are.
Diese Öffnungen 12a bis 12i haben jeweils den gleichen Innendurchmesser. These openings 12a to 12i each have the same inner diameter.
In einer dieser Öffnungen, bei der dargestellten Ausführungsforni in der Öffnung 12d, wird ein Markierstift 14 befestigt. Dieser Markierstift weist einen Schaft 16 mit einer Spitze 16a auf; der Schaft 16 hat beispielsweise einen Durchmesser von 3 mm. In one of these openings, in the embodiment shown in the opening 12d, a marking pen 14 is attached. This marker pen points a shaft 16 with a tip 16a; the shaft 16 has, for example, one 3 mm in diameter.
An den Schaft 16 des Markierstiftes 14 schließt sich eine kreisförmige Platte 18 an, deren Außenradius größer als der Innenradius der Öffnungen 12a bis 12i, also auch der Öffnung 12d ist. Der Markierstift 14 läuft schließlich in einem Gewindebolzen 20 aus, dessen Außendurehmesser etwas kleiner als der Innendurchmes ser der Öffnungen 12a bis 12ist Wie man aus der Figur erkennt, wird der Gewindebolzen 20 des Markierstiftes 14 in die Öffnung 12d gesteckt; ein Teil des Gewindebolzens 20 ragt aus der Öffnung 12d heraus, so daß auf diesen Teil eine Befestigungsmutter 22 aufgeschraubt werden kann und dadurch den Markierstift 14 an der Halterung 12 fixiert. The shaft 16 of the marking pen 14 is followed by a circular one Plate 18, the outer radius of which is greater than the inner radius of the openings 12a to 12i, i.e. also the opening 12d. The marker pen 14 finally runs in one Threaded bolt 20, the outer diameter of which is slightly smaller than the inner diameter This one of the openings 12a to 12 is As can be seen from the figure, the threaded bolt 20 of the marking pen 14 inserted into the opening 12d; part of the threaded bolt 20 protrudes from the opening 12d, so that a fastening nut on this part 22 can be screwed on and thereby the marking pen 14 on the holder 12 fixed.
Die Befestigungsmutter 22 weist ein Sackloch mit einer Gewindebohrung für das Einschrauben des Gewindebolzens 20 auf. The fastening nut 22 has a blind hole with a threaded hole for screwing in the threaded bolt 20.
Bei aufgeschraubter Befestigungsmutter 22 liegt die Platte 18 an der Innenseite der kreisbogenförmigen Halterung 12 an, so daß sich der Schaft 16 aufgrund des radialen Verlaufes der Öffnungen 12a bis 12i zum Mittelpunkt des Kreises hin erstreckt. Die Länge des Schaftes 16 ist so an den Radius des Kreises angepaßt, auf dem die kreisbogenförmige Halterung 12 liegt, daß sich das freie Ende 16a des Schaftes des Markierstiftes 14 im Mittelpunkt dieses Kreises befindet. When the fastening nut 22 is screwed on, the plate 18 rests on it the inside of the circular arc-shaped holder 12, so that the shaft 16 due to the radial course of the openings 12a to 12i to the center of the circle extends towards. The length of the shaft 16 is adapted to the radius of the circle, on which the circular arc-shaped holder 12 lies that the free end 16a of the Shank of the marker 14 is located in the center of this circle.
Eine weitere Öffnung der Halterung 12, bei der Ausführungsform nach der Figur die Öffnung 12i, nimmt eine Führungshülse 24 auf, die mit einer zentrischen Innenbohrung 24a versehen ist. Der Außendurehmesser der Führungshülse 24 ist so ausgelegt, daß sie in die Öffnungen 12a bis 12i paßt. Mittels einer Feststellschraube 26 kann die Führungshülse 24 in einer bestimmten radialen Lage in der Öffnung 12i arretiert werden. Another opening of the holder 12, in the embodiment according to the figure, the opening 12i, receives a guide sleeve 24 with a central Inner bore 24a is provided. The outer diameter of the guide sleeve 24 is like this designed to fit into openings 12a to 12i. By means of a locking screw 26, the guide sleeve 24 can be in a specific radial position in the opening 12i be locked.
Beispielsweise bei einer Operation an einem Kniegelenk wird der Markierstift 14, geführt durch die Arthroskopie, in das Kniegelenk eingeführt, bis seine freie Spitze 16a zu einer Stelle auf der Oberfläche eines Knochens gelangt, an dem sich die Öffnung der herzustellenden l3<>hrung befinden soll. Sobald diese optinlolle Stelle erreicht ist, wird der (;ewindeholzen 20 des Mirkierstif tes 14 in die Öffnung 12d der Halterllllg 12 chlgefühl t und der Markierstift 14 mittels der Bcfestigungsmutter 22 an der lHalterung 12 befestigt. Nach dem Anziehen der Gewindeverbindung liegt die Spitze 16a des Markierstiftes 14 im Mittelpunkt des Innenkreises der ll~llterung 12. For example, during an operation on a knee joint, the marker pen 14, guided by arthroscopy, inserted into the knee joint until its free Tip 16a comes to a point on the surface of a bone where the opening of the l3 guide to be produced should be located. Once this optinlolle Place is reached, the (ewindeholzen 20 of the Mirkierstif th 14 in the opening 12d the holder 12 and the marker pen 14 by means of the fastening nut 22 attached to the bracket 12. After tightening the threaded connection lies the tip 16a of the marking pen 14 in the center of the inner circle of the filter 12th
Die kreisbogenförmige Halterung 12 kann nun vorsichtig so um den Gewindebolzen 20 des Markierstiftes 14 gedreht werden, bis bei Einführung der Führungshülsc 24 in eine geeignete Öffnung, beim dargestellten Beispiel die Öffnung 12i, die Spitze der Führungshülse 24 zu einer Stelle auf der Oberfläche des Knochens gerichtet ist, an der sich, beispielsweise aus chirurgischen, aber auch aus anatomischen Gründen die andere Öffnung der Bohrung befinden sollte. Schiebt man nun die schematisch angedeutete Führungsnadel 28 durch die Bohrung 24a der Führungshülse 24 und bohrt sie durch den Knochen, so entsteht eine Vorbohrung, deren Öffnungen genau definiert und optimal auf die vorliegenden Operationsbedingungen abgestellt sind. The arcuate bracket 12 can now carefully so around the Threaded bolt 20 of the marking pen 14 are rotated until the introduction of the guide sleeve 24 into a suitable opening, in the example shown the opening 12i, the tip the guide sleeve 24 is directed to a location on the surface of the bone, to which, for example, for surgical, but also for anatomical reasons the other opening should be the hole. If you now move the schematically indicated guide needle 28 through the bore 24a of the guide sleeve 24 and drills through the bone, a pilot hole is created, the openings of which are precisely defined and are optimally geared to the existing operating conditions.
Sobald diese optimale Lage der Führungshülse 24 erreicht ist, wird sie mittels der Feststellschraube 26 arretier, so daß die Führungsnadel 28 auf übliche Weise eingeschraubt werden kann. Tritt die Führungsnadel 28 bei dieser Vorbohrung aus dem Knochen aus, so stößt sie direkt auf die Spitze 16a des Markierstiftes 16. As soon as this optimal position of the guide sleeve 24 is reached, they locked by means of the locking screw 26, so that the guide needle 28 to the usual Way can be screwed. If the guide needle 28 occurs in this pilot hole out of the bone, it hits the tip 16a of the marking pen 16 directly.
Nun kann die Feststellschraube 26 gelöst, die Führungshülse 24 aus der Öffnung 12i herausgezogen, die Befestigungsmutter 22 gelöst und die Halterung 12 und der Markierstift 14 entfernt werden. Anschließend wird auf übliche Weise ein hohler Bohrer auf die Führungsnadel 28 aufgesetzt, der dann die eigentliche Bohrung herstellt. Now the locking screw 26 can be loosened, the guide sleeve 24 out the opening 12i pulled out, the fastening nut 22 loosened and the bracket 12 and the marking pen 14 can be removed. Then it is done in the usual way a hollow drill is placed on the guide needle 28, which then the actual Hole manufactures.
Bei Operationen am Kreuzband des Kniegelenkes wird durch diese eigentliche Bohrung dann der Kreuzbandersatz gezogen, der anschließend am Knochen befestigt wird. During operations on the cruciate ligament of the knee joint, this is the actual Drilled then the cruciate ligament replacement is pulled, which is subsequently attached to the bone will.
Das freie Ende 16a des Markierstiftes 16 kann bei Bedarf mit einem Haken (nicht dargestellt) versehen sein, um das freie Ende am Knochen zu fixieren. The free end 16 a of the marker pen 16 can if necessary with a Hooks (not shown) may be provided to fix the free end to the bone.
