Abstract

The device has three main parts. It has a main screw (6) which has rounded head (8) with a hexagonal socket in it. The screw passes through a separate lower part and the underside of the screw head seats in a hole in the lower part. The rounded underside of the screw head matches the shape of the hole in the lower part so that a good fit occurs. On the side wall of the hole is a cylindrical section which has an internal thread. A separate top section to the implant has a corresponding internal thread which fits into the thread in the hole section and a hexagonal socket head.

Description

Die Erfindung richtet sich auf eine Anordnung zur Befestigung eines Im plantats, insbesondere eines abschnittsweise plattenförmigen Implantats, an einem Knochen des menschlichen Körpers mittels einer Schraube, wobei das Implantat eine Schraubenbohrung aufweist. The invention is directed to an arrangement for mounting an in plantats, in particular a plate-shaped sections of the implant, wherein the implant comprises a bone of the human body by means of a screw, a bolt hole.

Derartige Anordnungen dienen beispielsweise dazu, im Bereich der Hals wirbelsäule Platten zum Verbinden von Wirbelkörpern anzuschrauben. Such assemblies serve, for example, to screw spine plates for connecting vertebrae in the neck. Wei terhin kommt als derartiges Implantat beispielsweise eine Hüftpfanne bei Hüftgelenkprothesen in Betracht. Wei terhin comes as such an implant such as a hip socket hip joint prostheses into consideration.

Dabei stellt sich das Problem, daß es häufig schwierig ist, für eine ein zudrehende Schraube eine Bohrung so anzubringen, daß diese Bohrung exakt senkrecht zu der Anlageebene des Schraubenkopfes verläuft. In this case,, the problem arises that it is often difficult to install such a bore for a screw zudrehende that this bore runs exactly perpendicular to the plane of abutment of the screw head. Dies resultiert daraus, daß die Bohrung intraoperativ nicht mit der gewün schten Genauigkeit eingebracht werden kann, oder daß aufgrund des phy siologischen Knochenverlaufes eine schrägverlaufende Bohrung vorteilhafter wäre. This results from the fact that the bore can not be incorporated with the gewün schten accuracy intraoperatively, or that a transverse bore would be more advantageous due to the phy-physiological bone path.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Befe stigung eines Implantats mittels einer Schraube derart zu realisieren, daß die Schraube erforderlichenfalls schräg zu der Anlagefläche des Schrau benkopfes verlaufen kann, wobei gleichwohl ein zuverlässiger Halt der Verschraubung gewährleistet sein soll. On this basis, the invention has the object of providing a BEFE stigung an implant by a screw to realize such a way that the screw may obliquely extend benkopfes to the contact surface of Schrau necessary, wherein nevertheless a reliable retention of the screw is to be ensured.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schraube einen zur Unterseite hin kugelkalottenförmigen Kopf aufweist, daß die Un terseite der Schraubenbohrung im Implantat einen kugelkalottenförmigen Seitenwand-Abschnitt aufweist, daß sich an dem kugelkalottenförmigen Ab schnitt der Seitenwände ein zylindrischer Abschnitt mit einem Innengewin de anschließt, und daß ein Schraubeinsatz ein korrespondierendes Außen gewinde und eine Sechskant-Schraubausnehmung aufweist, wobei an der Oberseite der Schraube eine korrespondierende Sechskant-Schraubausneh mung vorgesehen ist. This object is inventively achieved in that the screw has a back spherical cap to the bottom head, that the Un underside of the screw hole in the implant having a spherical segment-shaped side wall section that in the spherical cap-shaped from the side walls cut a cylindrical portion with an internal threaded de connects and that a screw insert a corresponding external thread and a hexagonal Schraubausnehmung, wherein a corresponding hexagonal Schraubausneh mung is provided at the top of the screw.

Durch diese Ausgestaltung ist es möglich, die Schraube durch die Schrau benbohrung zu stecken und sie mittels eines Sechskant-Schlüssels einzu drehen, wobei die Längsachse der Schraubenbohrung durchaus auch schräg zu der Anlageebene des Schraubenkopfes verlaufen kann. By this configuration, it is possible to insert the screw through the Schrau benbohrung and rotate einzu by means of a hexagonal key, wherein the longitudinal axis of the screw hole may well also extend obliquely to the bearing plane of the screw head. Am Ende des Einschraubvorganges gelangt das untere, dh in Einschraubrichtung vorne liegende Ende des Schraubenkopfes zur Anlage an den unteren, dh in Einschraubrichtung äußeren Innenwand-Abschnitt der Schraubenboh rung, wobei eine flächige Anlage auch bei schräg verlaufender Schrau benbohrung gewährleistet ist. At the end of screwing the lower, that is in front in the screwing-in direction reaches the end of the screw head to rest on the bottom, ie in the screwing-outer inner-wall portion of the Schraubenboh tion, wherein a surface contact is benbohrung ensured even at oblique Schrau.

Mit dem gleichen Sechskant-Schrauber, mit welchem die Schraube einge dreht wurde, wird nun anschließend der Schraubeinsatz eingedreht, wobei der Schraubeinsatz gegen die Oberseite des Schraubkopfes und diesen wie derum gegen die kugelabschnittförmige Innenwand der Schraubenbohrung drückt. With the same hexagon head screws, with which the screw is screwed is, the threaded stud is screwed now then, the screw insert against the top of the screw head and presses as derum against the spherical segment-shaped inner wall of the screw hole.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß der Innendurchmesser des zylinderförmigen Gewindeabschnitts deutlich größer ist als der Außendurchmesser des Schraubenkörpers. In a further embodiment of the invention may be provided that the inner diameter of the cylindrical threaded portion is significantly larger than the outer diameter of the screw body. Hierdurch ist es mög lich, daß das erforderliche Spiel für eine schräg einzusetzende Schraube frei bleibt. This makes it possible, please include that the required clearance for a screw to be inserted obliquely remains free.

Günstigerweise kann sich von der Oberseite des Schraubenkopfes ein Ku gelkalottenabschnitt nach oben wegerstrecken, wobei der Schraubeinsatz eine kugelkalottenförmige Ausnehmung etwa korrespondierender Form aufweisen kann. Conveniently, can extend away from the top of the screw head a Ku gelkalottenabschnitt upwards, said screw insert can have a spherical segment-shaped recess approximately corresponding shape. Hierdurch wird eine günstige Übertragung des Anpreß druckes gewährleistet. This results in a favorable transmission of the pressing is pressure ensured.

Weiterhin kann vorgesehen sein, daß die Oberseite des Kugelkalottenab schnittes aufgerauht ausgebildet ist, um im angetrockneten Zustand einen hohen Reibschluß zu ermöglichen. Furthermore, it can be provided that the top of Kugelkalottenab section is formed roughened in order to enable a high frictional engagement in the dried state.

Vorteilhafterweise ist der Krümmungsradius des Kugelkalottenabschnittes kleiner als der Krümmungsradius der kugelkalottenförmigen Ausnehmung des Schraubeinsatzes. Advantageously, the radius of curvature of Kugelkalottenabschnittes is smaller than the radius of curvature of the spherical cap-shaped recess of the screwdriver bit.

Wenn darüber hinaus günstigerweise vorgesehen ist, daß sich an die ku gelkalottenförmige Ausnehmung ein Zylinderabschnitt anschließt, dessen Radius kleiner ist als der Radius des Kugelkalottenabschnittes, ist unab hängig von der Winkelstellung der Mittel-Längs-Achse in jedem Fall ge währleistet, daß die Unterkante des Zylinderabschnittes sich auf der Oberseite des Kugelkalottenabschnittes eingräbt und an dieser aufgerauh ten Oberfläche zuverlässig festgelegt ist. If is conveniently provided in addition, that a cylindrical section adjoins the ku gelkalottenförmige recess, whose radius is smaller than the radius of Kugelkalottenabschnittes is inde pendent of the angular position of the central longitudinal axis of in each case ge ensured that the bottom edge of the cylinder section is digs on top of Kugelkalottenabschnittes and reliably determined at this up rough th surface.
