Description
Schiene fUr chirugische Zwecke zur Verbindung von gebrochenen Knochenteilen Die Erfindur.g betrifft eine Schiene für chirugische-Zwecke zur Verbindung von gebrochenen Knochenteilen, die über in diese eingreifenden Schrauben mit der Schiene verbunden sind. Splint for surgical purposes to connect broken bone parts The invention relates to a splint for surgical purposes for connecting broken ones Bone parts connected to the splint via screws engaging in them are.
ns ist bereits eine Schiene bekannt, die mittels Schrauben an die Knochenbruchstücke befestigt werden.ns a rail is already known that is attached to the Bone fragments are attached.
Diese starre Verbindung zwischen Schiene und Knochen macht es unmöglich, Längs- und Querverschiebungen, die oei Belastung des Knochens durch Bewegungs- und Wachstumseinflüßen entstehen, auszugleichen. Die Folge davon ist ein Ausbrechen der Gewindegänge im Knochen und damit ein ungewolltes Lösen der Schraubverbindung.This rigid connection between the splint and the bone makes it impossible Longitudinal and transverse displacements, which oei stress on the bone by movement and Growth influences arise to compensate. The result is a breakout the threads in the bone and thus an unintentional loosening of the screw connection.
Um diesen Nachteilen abzuhelfen, wird erfindungsgemäß vorgeschlagen, den Schraubenkopf und/oder Schraubenschaft mit einer elastisch nachgiebigen Kunststoffeinlage zu umgeben.In order to remedy these disadvantages, it is proposed according to the invention that the screw head and / or screw shaft with an elastically flexible plastic insert to surround.
Durch diese Lösung kann sich die Schraube durch Verdrängen des elastischen Kunststoffes in begrenztem Umfang bewegen. Somit ist es-möglich, daß sich die Schraube z.B. der Verschiebung der Bohrung beim Wachsen. des Knochens nach dem Anbringen-der Schiene anpassen kann.With this solution, the screw can be displaced by the elastic Plastic to a limited extent move. Thus it is possible that the screw e.g. the displacement of the bore when growing. of the bone after attaching the splint.
In zweckmäßiger Weise kann nach einem weiteren Merkmal der Erfindung die elastische Kunststoffeinlage über dem Schraubenkopf nach innen umgefaßt. sein.Expediently, according to a further feature of the invention the elastic plastic insert encompassed inwards over the screw head. be.
Damit ist noch- zusätzlich eine Sicherung gegen Herausfallen und Lösen der Schraube aus dem Bohrloch geschaffen..This also provides protection against falling out and loosening created by the screw from the borehole ..
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt.Two exemplary embodiments of the invention are shown in the drawing.
Es zeigen: Figur 1 Seitenansicht einer'Kunststoffeinlage im Schnitt, .1 Figur 2 Seitenansicht einer Kunststoffeinlage mit bundförmigem Ansatz im Schnitt Figur 1 zeigt eine elastische-Kunstsroffeinla6e 1, die in einer für den Schraubenkopf vorgesehenen Senkung 2 der Schiene 3 eingepaßt ist. Der Kopf 4 und ein Teil des Schaftes 5 einer Schraube 6, welche die Schiene 3 mit dem Knochenbruchstück 7 verbindet, sind in der Runststoffeinlage 1 eingebettet. Figur 2 zeigt im-wesentlichen dieselbe Kunststoffeinlage 1' in Figur-1, nur daß bei diesem Ausführungsbeispiel zusätzlich die Stirnfläche des Schraubenkopfes teilweise von einem bundförmigen Ansatz umfaßt wird. They show: FIG. 1 side view of a plastic insert in section, .1 Figure 2 side view of a plastic insert with a collar-shaped extension in section Figure 1 shows an elastic-Kunstsroffeinla6e 1, which in one for the screw head provided countersink 2 of the rail 3 is fitted. The head 4 and part of the Shaft 5 a screw 6 which connects the splint 3 to the bone fragment 7, are embedded in the plastic insert 1. Figure 2 shows essentially the same Plastic insert 1 'in Figure-1, only that in this embodiment in addition the end face of the screw head partially encompassed by a collar-shaped projection will.
Die Kunststoffeinlage ist keineswegs auf die in der Zeichnung dargestellten Ausführungsformen beschränkt, sondern kann ohne den Erfindungsgedanken zu verändern, jede beliebige Form aufweisen. The plastic insert is by no means limited to that shown in the drawing Embodiments are limited, but can be used without changing the concept of the invention, have any shape.
