Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Ausrichten und Stabilisieren von Knochenteilen.The invention relates to a device for Align and stabilize bone parts.
Bei der rekonstruierenden Chirurgie ist es erforder lich, an den Knochenteilen als Implantat Hacken, Schrauben oder Drahtschlingen anzubringen, die dann mittels Stangen oder Platten fixiert werden. Diese Hacken, Schrauben oder Drahtschlingen können je nach Anwendungsfall im Körper verbleiben oder nach der Hei lung des Knochens wieder entnommen werden. It is required for reconstructive surgery Lich, as an implant hoes on the bone parts, Attach screws or wire loops, which then can be fixed using rods or plates. This Chopping, screwing or wire loops can vary depending on Use case remain in the body or after hei bone can be removed again.
Dabei besteht allgemein das Problem, daß es zunächst erforderlich ist, den gebrochenen Knochen auszurichten und nach dem Ausrichtvorgang die Knochenteile möglichst fest zu fixieren. Anders ausgedrückt, ist es erforder lich, zunächst eine "lose" Verbindung herzustellen, die dann nach der Ausrichtung der Knochenteile "verfestigt" wird.The general problem here is that it is initially is necessary to align the broken bone and after the alignment process the bone parts if possible to fix firmly. In other words, it is required Lich, first create a "loose" connection that then "solidified" after the alignment of the bone parts becomes.
Zur Lösung dieses Problems sind bislang die verschie densten Vorschläge unterbreitet worden:So far, there are various solutions to this problem Most suggestions have been made:
Exemplarisch wird auf die FR-A-83 07 450 verwiesen, in der ein Chirurgie-Besteck beschrieben ist, das auch unter dem Namen Cotrel-Dubousset-Instrumentarium (CD) bekannt geworden ist. Weitere Vorschläge sind in den US-PSen 4 913 134 und 4 790 297 beschrieben.As an example, reference is made to FR-A-83 07 450, in who described surgical cutlery that too under the name Cotrel-Dubousset-Instrumentarium (CD) has become known. Further suggestions are in the U.S. Patent Nos. 4,913,134 and 4,790,297.
Keiner der bekannten Vorschläge vermag alle Anforderun gen hinsichtlich Festigkeit der Verbindung und/oder Einfachheit des Aufbaus und damit Kostengünstigkeit zu erfüllen.None of the known proposals can meet all of the requirements conditions regarding the strength of the connection and / or Simplicity of construction and thus cost effectiveness too fulfill.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrich tung zum Ausrichten und Stabilisieren von Knochentei len anzugeben, die einerseits einfach aufgebaut ist und die als Implantate Standardbauteile verwendet, und die andererseits nach der Justierung der Knochenteile eine feste und insbesondere drehsteife Verbindung der Teile herstellt.The invention has for its object a Vorrich device for aligning and stabilizing bone len, which is simple on the one hand and which uses standard components as implants, and which on the other hand, after adjusting the bone parts firm and especially torsionally rigid connection of the parts manufactures.
Eine erfindungsgemäße Lösung dieser Aufgabe ist im Anspruch 1 angegeben. Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.An inventive solution to this problem is in Claim 1 specified. Developments of the invention are the subject of the dependent claims.
Die Erfindung wird nachstehend anhand der Zeichnung näher beschrieben, in der zeigen:The invention is described below with reference to the drawing described in more detail in the show:
Fig. 1 eine Seitenansicht einer erfindungsgemäßen Vorrichtung, und Fig. 1 is a side view of a device according to the invention, and
Fig. 2 eine Aufsicht auf die Vorrichtung. Fig. 2 is a plan view of the device.
Erfindungsgemäß weist die Vorrichtung wenigstens zwei (nicht dargestellte) Implantat-Elemente, von denen jedes die Form eines Hackens, einer Schraube oder gege benenfalls einer Schlinge hat. Die Implantat-Elemente sind in bekannter Weise so ausgebildet, daß sie eine Verbindung mit dem jeweiligen Knochenteil herstellen können. Insoweit sind die Elemente bekannt, so daß sie nicht näher beschrieben werden müssen.According to the invention, the device has at least two (not shown) implant elements, of which each in the form of a chop, screw or counter also has a noose. The implant elements are designed in a known manner so that they are a Establish connection with the respective bone part can. In this respect, the elements are known so that they need not be described in more detail.
Den Implantat-Elementen sind Verbindungselemente zuge ordnet, die in den Figuren mit dem Bezugszeichen 2 ver sehen sind. Die Verbindungs-Elemente 2 sind dem jewei ligen Implantat-Element auf beliebige Weise lösbar oder einstückig verbunden.The implant elements are assigned connecting elements, which can be seen in the figures with the reference numeral 2 . The connecting elements 2 are the respective implant element releasably or integrally connected in any way.
Erfindungsgemäß sind die proximalen Enden der Verbin dungs-Elemente 2 gabelförmig ausgebildet. In diese Gabeln ist jeweils eine Stange (1) einsetzbar, die insbesondere ein Gewinde aufweisen kann, mit dem sie in das gabelförmige proximale Ende des Verbindungselements (2) einschraubbar ist.According to the proximal ends of the connec tion elements 2 are fork-shaped. A rod ( 1 ) can be inserted into each of these forks, which can in particular have a thread with which it can be screwed into the fork-shaped proximal end of the connecting element ( 2 ).
Weiterhin ist eine Mutter (4) vorgesehen, die auf das proximale Ende des jeweiligen Verbindungselements (2) derart auf schraubbar ist, daß die das Verbindungsele ment gegenüber der Stange (1) fixiert. Zur Verbesserung der Fixierung kann zwischen Mutter (4) und Stange (1) ein Spannelement (3) eingesetzt sein.Furthermore, a nut ( 4 ) is provided, which is screwed onto the proximal end of the respective connecting element ( 2 ) in such a way that the element against the rod ( 1 ) is fixed. To improve the fixation, a clamping element ( 3 ) can be inserted between the nut ( 4 ) and the rod ( 1 ).
Vorstehend ist die Erfindung ohne Beschränkung des all gemeinen Erfindungsgedankens anhand eines Ausführungs beispiels exemplarisch beschrieben worden.Above is the invention without limitation of all general inventive idea based on an execution has been described as an example.
