Abstract

Artificial joint is fixed in place by a fastening element consisting of a basic body (1) with the joint head and a metal foil (2) attached to the shaft. The foil is pref. of a number of layers, for compatibility, e.g. Ti, and adhesion, e.g. Fe, embossed with a fine pattern and applied in small folds. The fastening element is filled with liquid polymerisable synthetic resin (7), expanding the foil. ADVANTAGE - Adapts to the required shape and can be mfd. cheaply as standard.

Description

Künstliche Gelenke werden überwiegend mit den Knochen verschraubt. Artificial joints are mostly screwed to the bone. Dabei treten im Gewindeteil hohe lokale Belastungen des Knochenmateriales auf, die notwendig sind um ein Lockern der Schrauben bei den wechselnden Gebrauchs kräften zu verhindern. Here occur in the threaded part to high local stresses on the bone material necessary to loosening of the screws in the changing use to prevent forces. Sie können jedoch die Gebrauchsdauer wesentlich verkürzen, wenn die Tragfähigkeit des Knochens zu gering ist oder sich dieser aufweitet. However, you can significantly shorten the service life when the bearing capacity of the bone is too low or this expands. Man vermeidet diese Probleme erfolgreich durch den Einsatz von Adapter stücken, die anhand von Computer-Thomogrammen individuell für den Patienten hergestellt werden und die Kräfte groß flächig an den Knochen weiterleiten. To avoid these problems successfully through the use of adapter pieces that are produced using computer-Thomogrammen individually for the patient and transmit the forces over a large area of ​​the bone. Durch den notwendigen Einsatz technisch aufwendiger Geräte sind die Kosten hoch und die Einsatzmöglichkeiten auf wenige, gut ausgerüstete Krankenhäuser begrenzt. Due to the necessary use of technically complicated equipment costs are high and limits the possibilities to a few, well-equipped hospitals.

Die im Folgenden beispielhaft beschriebene Erfindung bie tet durch die selbsttätige Formanpassung und die Möglich keit der Serienfertigung in genormt abgestuften Größen eine preiswerte, gleichwertige Alternative. The exemplary invention described below bie tet by the automatic conformability and the possi bility of series production in standardized graduated sizes an affordable, viable alternative.

Das Befestigungselement (siehe Schnittdarstellung Fig. 1) besteht aus einem Grundkörper ( 1 ) mit dem Gelenkkopf und einer, mit dem Schaft verbundenen Metallfolie ( 2 ), vorzugs weise aus dem physiologisch gut verträglichen Metall Titan hergestellt oder damit beschichtet. The fastener (see illustration in Fig. 1) consists of a basic body (1) to the joint head, and one connected to the stem metal foil (2), preferably, from the physiologically well-tolerated metal titanium manufactured or coated therewith. Die Metallfolie ist mit einem feinen Noppenmuster geprägt und in kleinen Falten ge legt. The metal foil is embossed with a fine nap pattern and ge in small wrinkles inserted. Das Befestigungselement wird in eine teilweise bear beitete Bohrung eingeführt und zunächst mit kleinen Schrau ben ( 3 ) provisorisch in der gewünschten Position am Knochen ( 4 ) befestigt und dann über den Zentralkanal ( 5 ) und die Verteilerkanäle ( 6 ) mit flüssigem, polymerisierendem Kunst harz ( 7 ) unter mäßigem Druck befüllt. The fastener is inserted into a partially bear beitete bore and first ben with small Schrau (3) temporarily in the desired position on the bone (4) and then through the central channel (5) and the distribution channels (6) with liquid, polymerized resin (7) filled under moderate pressure. Die Metallfolie ( 2 ) bläht sich dabei auf und legt sich optimal an praktisch jede beliebige Knochenform an. The metal foil (2) inflates it and puts itself perfectly to virtually any bone shape. Am Knochen können vorher Hohlkehlen oder genau quer zur Belastungsrichtung liegende Hinterschneidungen angebracht werden, in die sich die Folie legt und damit entsteht mit dem Aushärten des Kunstharzes eine zuverlässige, unlösbare Verankerung. The bone before fillets or exactly transverse to the loading direction undercuts can be attached, in which the film settles and thus arises with the curing of the resin a reliable, non-releasable anchorage.

Um Schwachstellen durch eingeschlossene Luft zu vermeiden wird der Hohlraum zwischen Grundkörper ( 1 ) und Metallfolie ( 2 ) vor dem Befüllen luftleer gepumpt, bzw. bereits vom Hersteller so angeliefert. In order to avoid weak points due to trapped air in the cavity between the base body (1) and metal foil (2) is pumped empty of air prior to filling, or already supplied by the manufacturer so on. Bei Anwendungen mit hohen Be lastungen kann das Kunstharz mit Füllstoffen wie Keramik pulver, Glas- oder Kohlefasern durchmischt werden, um die Festigkeit zu erhöhen und das Schwinden beim Aushärten zu vermindern. For applications with high loads can Be the resin with fillers such as ceramic powder, glass or carbon fibers are mixed in order to increase the strength and reduce shrinkage during curing. Damit während des Aushärtevorganges weiter ge arbeitet werden kann, wird der Zuführkanal mit einer sehr langen Verschlußschraube ( 8 ) verschlossen. Can be thus operates during the curing process further ge, the supply channel is closed with a very long closing screw (8). Durch die Volumen verdrängung entsteht ein statischer Druck, der die Metall folie ( 2 ) in ihrer Position und Form hält. Due to the volume displacement, a static pressure which maintains the metal sheet (2) in position and shape. Ein Hohlraum im Inneren der Verschlußschraube und das Ende des Zentralkanals sind mit geschlossenporigem Schaumstoff ausgefüllt, der sich beim Evakuieren nur mäßig ausdehnt und bei Überdruck als Gas-Feder wirkt und damit einerseits eine allzu starke Druckerhöhung durch die Volumenverdrängung der Verschluß schraube verhindert und andererseits während des Aushärtens, das durch die Körperwärme überwiegend von außen nach innen fortschreitet, das schwindende Volumen durch die Vorräte im Zentralkanal ergänzend nachschiebt. A cavity inside the locking screw and the end of the central channel are filled with closed-cell foam, the only moderately expands upon evacuation and acts as a gas spring at superatmospheric pressure and thus on the one hand a too strong pressure increase by the volume displacement of the locking bolt is prevented and on the other hand during the curing that proceeds through the body heat predominantly from outside to inside, the diminishing volume of the stocks in the central channel in addition nachschiebt.

Zusätzliche Armaturen ermöglichen ein zügiges Arbeiten, in dem ein Verteilerhahn ( 9 ) in der Position a den Innenraum mit einer Vakuumpumpe ( 10 ) verbindet, in der Position b ab schließt, in der Position c den Vorlauf des Kunstharzes aus den nur schematisch dargestellten Vorratskartuschen ( 11 ) mit der Mischdüse ( 12 ) solange das Mischungsverhältnis un zuverlässig ist in den Abfallbeutel ( 13 ) ableitet und end lich in Position d den Innenraum mit gut durchmischtem Kunstharz befüllt. Additional fittings allow a rapid work, in which a distributor valve (9) in the position a the interior with a vacuum pump (10), closes in the position b from c the flow of the resin (in the position of the only schematically illustrated storage cartridges 11) (with the mixing nozzle 12) as long as the mixing ratio is un reliable (derived in the waste bag 13) and end Lich d filled the interior with well mixed resin in position.

Verschlußschrauben mit breiten Dichtringen für den Zuführ kanal ermöglichen einen völligen Abschluß zwischen Harz und Gewebe zu erzeugen und vermeiden so allergische Reaktionen durch die oft aggressiven Komponenten des Kunstharzes. Plugs with wide sealing rings for the feed channel allow to produce a complete seal between the resin and fabric and avoid allergic reactions by the often aggressive components of the resin. Neben der dargestellten, zentral expandierenden Form sind auch Ausführungen mit analoger Funktion herstellbar, die einen Knochen, wie in Fig. 2 dargestellt, umschließen. In addition to the illustrated centrally expanding shape, versions with analog function can be produced which surround a bone, as shown in FIG. 2.
