Description
Spannstückverbindungen für Implantate Die Erfindung betrifft eine Vorrichtung zum dauerhaften, zementfreien Befestigen von Implantaten im Inneren von Röhrenknochen. Clamping piece connections for implants The invention relates to a Device for permanent, cement-free fastening of implants inside of long bones.
Knochenendoprotbesen werden immer häufiger in der Humanmedizin eingesetzt. Verschiedene Substitutionsprodukte sind bereits für Implantate vorhanden. Als Werkstoffe kommen Metallegierungen, Kunststoffe und technische Keramik-infrage, aber jedes dieser Materialien besitzt gewisse Nachteile, wenn man es als Implantat einsetzt. Der Kunststoff z. B. verträg sich oft sehr schlecht mit dem Organismus, so daß er schon nach kürzester Zeit wieder aus dem Körper entfernt werden muß. Außerdem besitzt er keine besonders hohe chemische Widerstandsfähigkeit und ist auch nicht genügend volumenbaständig. Bei den Metallverbindungen gibt es bereits Werkstoffe, z. B. Kobalt-Chromstahl, die weit besser mit dem lebenden Organismus verfraglich sind als Kunststoffe, aber zum größten Teil müssen solche Implantate aus Metallen bzw. Metallegierungen mit Zementen oder Klebern in oder an den Knochen gekittet werden. Die keramischen Werkstoffe sind zwar inert und korrosionsbeständig gegenüber dem Organismus, aber man befürchtet, daß ein solches Material, wie es in der deutschen Offenlegungsschrift 2 134 316 beschrieben wird, aufgrund seines spröden Charakters, z. B. beim Einschlagen eines Aluminiumoxid-Schaftes, beschädigt oder sogar zerstört wird. Außerdem benötigt man ebenfalls Kitte, Zemente oder Kleber, um gewisse Dauerverbindungen herzustellen.Bone endoprotectomy brooms are being used more and more frequently in human medicine. Various substitution products are already available for implants. As materials Metal alloys, plastics and technical ceramics are possible, but every one these materials have certain disadvantages when used as an implant. The plastic z. B. often gets along very badly with the organism, so that he must be removed from the body again after a very short time. Also owns it does not have a particularly high chemical resistance and is also not sufficient volume-constrained. In the case of metal connections, there are already materials such. B. cobalt chrome steel, which are far better interrogative with the living organism than plastics, however For the most part, such implants made of metals or metal alloys have to be included Cements or adhesives can be cemented into or onto the bones. The ceramic materials are inert and corrosion-resistant to the organism, but it is feared that that such a material as it is in the German Offenlegungsschrift 2 134 316 is described due to its brittle character, e.g. B. when hitting a Aluminum oxide shaft, is damaged or even destroyed. You also need also putty, cement or glue to make certain permanent connections.
Daher ist es die Aufgabe der vorliegenden Erf ndung, bei Endoprothesen die Verwendung von Klebern und Zementen zum Befestigen der Implantat-Teile aus den in der Fachwelt bekannten Gründen zu vermeiden, und daß beim Einbau keine Gefahr einer Beschädigung des Implantat-Materials besteht.It is therefore the object of the present invention in the case of endoprostheses the use of adhesives and cements to fix the implant parts from the to avoid reasons known in the art, and that there is no danger during installation there is damage to the implant material.
Die erfindungsgemäße Spannstückverbindung für ein Implantat ist als Lösung der vorstehend genannten Aufgabe dadurch gekennzeichnet, daß in den Raum zwischen Corticalis und dem teilweise hohlen Implantatschaft ein Kugelhaufwerk eingebracht ist und dieses in etwa senkrechter Richtung zur Corticaliswand anpressend wirkt, indem ein in einem Längsschlitz beweglicher Querstift im hohlen Teil des Schaftes auf das Haufwerk drückt.The clamping piece connection according to the invention for an implant is as Solution to the above-mentioned object, characterized in that in the room Between the corticalis and the partially hollow implant shaft, a ball pile was introduced and this has a pressing effect in an approximately perpendicular direction to the cortical wall, by a transverse pin movable in a longitudinal slot in the hollow part of the shaft presses on the pile.
Auf den Zeichnungen ist dieser Erfindungsgedanke beispielsweise dargestellt, und zwar zeigen in Teil-L-ngsschnitten Fig. 1: ein Ausführungsbeispiel für den Fall eines Knochens mit gekrümmter Längsachse, beispielsweise eines Oberschenkelknochens.This concept of the invention is shown in the drawings, for example, namely, in partial longitudinal sections, FIG. 1 shows an exemplary embodiment for the case a bone with a curved longitudinal axis, for example a femur.
Fig. 2: einen Teil-Schnitt zu Fig. 1, und zwar um 900 gedreht. FIG. 2: a partial section to FIG. 1, rotated by 900.
Die Einzelheiten und die Merkmale der Erfindung sind aus der nachfolgenden Beschreibung zu entnehmen.The details and features of the invention are from the following To be found in the description.
Nachdem das Implantat 2 nebst Kugelhaufwerk 6, 7 und die Zylinderkörper 5 in den vorher ausgefrästen Hohlraum des Röhrenknochens ohne Anwendung von Zwang gebracht worden ist,und man mittels eines Werkzeugs, vorzugsweise eines Drehrnomentenschlüssels, die Schraube 9, vorzugsweise in Gestalt einer Inbusschraube 11, am Kopf des Implantates angezogen hat, drückt diese auf die stark abgerundeten Zylinderkörper 5 im hohlen Implantatteil, und diese wiederum übertragen den Druck auf den freibeweglichen Querstift 4, der in einen Längsschlitz 3 eingepaßt ist, sowie weiterhin auf die konische Hülse 13.After the implant 2 together with the ball pile 6, 7 and the cylinder body 5 into the previously milled hollow space of the long bone without the use of force has been brought, and using a tool, preferably a torque wrench, the screw 9, preferably in the form of an Allen screw 11, on the head of the implant dressed has, this presses on the strongly rounded cylinder body 5 in the hollow implant part, and these in turn transfer the pressure to the freely movable transverse pin 4, the is fitted into a longitudinal slot 3 and also onto the conical sleeve 13.
Der Raum zwischen dem unteren Verschlußstück 8 und der Hülse 13 ist mit Kugeln aus Keramik oder Metallen ausgefüllt. Dieses Kugelhaufwerk zeigt die wirkung einer Pseudo-Flüssigkeit, wenn die Einzelelemente gleich oder annähernd gleich im Durchmesser sind und ein Druck ausgeübt; wird. Dadurch besteht aber die Gefahr, daß die Kugeln am unteren Verschlußstück 8 bzw. an der Hülse 13 vorbeigleiten können; deshalb whlt man für die untere und obere Querschicht des Kugelhaufwerks etwas größere Kugeln 7. Der Druck in Richtung der Knochenlängsachse auf den Kugelhaufen bewirkt ein Ausweichen und Anpressen der kugeln in Richtung zur Corticaliswand 1. Damit ist ein Verkeilen des Implantats im Röhrenknochen erreicht.The space between the lower closure piece 8 and the sleeve 13 is filled with ceramic or metal balls. This pebble shows the effect of a pseudo-liquid, if the individual elements are the same or approximately are equal in diameter and a pressure is applied; will. But because of this, the Danger that the balls slide past the lower locking piece 8 or the sleeve 13 can; therefore one chooses for the lower and upper transverse layer of the pebble bed slightly larger spheres 7. The pressure in the direction of the longitudinal axis of the bones on the globular cluster causes the balls to evade and press in the direction of the cortical wall 1. This wedges the implant in the long bone.
Der obere Kugelhaufen 12 dient im allgemeinen lediglich zur Wahrung der Abstände zwischen Implantat und Corticalis. Gegebenfalls kann eine zusätzliche Sicherung am Kopf des Implantates durch ein weiteres Druckelement 10 erfolgen, indem sich nach dem gleichen Prinzip die Kugeln 12 im Knochengewebe fest verankern.The upper pebble pile 12 is generally only used for preservation the distance between the implant and the cortical bone. If necessary, an additional Secured to the head of the implant by a further pressure element 10 by The balls 12 anchor themselves firmly in the bone tissue according to the same principle.
Als Materialien für die erfindungsgemäße Vorrichtung sind keramische Werkstoffe, vorzugsweise Aluminiumoxid oder Verbundwerkstoffe vorgesehen, die entweder dicht, porös oder zumindest oberflächenporös sind.Ceramic materials are used as materials for the device according to the invention Materials, preferably alumina or composites, are provided that either are dense, porous or at least porous on the surface.
Damit nach dem ärztlichen Eingriff Entzündungen weitgehend vermieden werden, ist an geeigneter Stelle ein Pharmaka-Depot angebracht.This largely avoids inflammation after the medical intervention a pharmaceutical depot is attached at a suitable location.
Durch die erfindungsgemäßen konstruktiven Maßnahmen hat die Vorrichtung Vorteile gegenüber den bereits bekannten Einbaumöglichkeiten von Implantaten in Röhrenknochen, insbesondere ein Vermeiden schlagartiger Beanspruchungen wehren des Operierens. Ferner, daß eine leichte und sichere Verankerung des Implantats durch ein Kugelhaufwerk im Inneren des Röhrenknochens erfolgt,wobei Zemente, Kitte oder dgl. nicht benötigt sind. Außerdem hat das Kugelhaufwerk noch den Vorteil, daß neu gebildetes Organgewebe leicht in die Hohlraume des Laufwerkes einwachsen kann. Diesen Vorgang kann man noch unterstützen, indem die Kugeln ebenfalls eine-poröse Oberflache aufw#eisen.Due to the structural measures according to the invention, the device Advantages over the already known installation options for implants in Long bones, especially avoiding sudden stresses, defend the Operating. Furthermore, that the implant can be anchored easily and securely A pile of pebbles takes place inside the long bone, using cement, putty or Like. Are not required. In addition, the ball pile has the advantage that it is new Organ tissue formed can easily grow into the cavities of the drive. This one The process can still be supported by the balls also having a porous surface exhibit.
