Abstract
Description
Die Erfindung befasst sich mit einer Vorrichtung zur dorsalen Stabilisierung der thorakolumbalen Wirbelsäule. Hierzu gibt es ein modulares System, welches ein Carbon-Composite-Stabsystem und polyaxiale und monoaxiale Titan-Schrauben umfasst. Kohlenstofffaserverstärkte Kunststoffe, wie ein Carbon-Composite-Stab, werden in der Medizintechnik insbesondere dort eingesetzt, wo hohe mechanische Festigkeiten, ein lastverteilendes Design und Röntgentransparenz gefordert werden. Bei einer solchen bekannten Vorrichtung wird in das Wirbelpedikel eine vorzugsweise aus Titan bestehende Schraube eingebracht, an deren Kopf eine Klemmschraube vorgesehen ist, welche einen eingelegten Carbon-Composite-Stab mittels Klemmen fixiert.The The invention relates to a device for posterior stabilization the thoracolumbar spine. There is a modular one for this System comprising a carbon composite rod system and polyaxial and monoaxial titanium screws. Carbon fiber reinforced Plastics, such as a carbon composite rod, are used in medical technology in particular used where high mechanical strength, a load-distributing Design and X-ray transparency are required. At a such known device is in the vortex pedestal one preferably made of titanium screw introduced at the head of a clamping screw is provided, which means an inserted carbon composite rod Fixed clamps.

Nach der einleitend beschriebenen Vorrichtung zur dorsalen Stabilisierung der thorakolumbalen Wirbelsäule, bei der ein Carbon-Composite-Stab mittels einer Klemmschraube am Klemmbereich fixiert wird, treten gerade in diesem Klemmbereich Verformungen an der Oberfläche des Stabes auf. Durch die Reibung der Metallkomponenten der Schraube am Carbon-Composite-Stab werden insbesondere Carbonpartikel als Abrieb erzeugt, welche im Bereich der Stabilisierungsvorrichtung somit im Körper verbleiben.To the initially described device for dorsal stabilization the thoracolumbar spine, where a carbon composite rod is fixed by a clamping screw on the clamping area, step deformations on the surface especially in this clamping area of the staff. Due to the friction of the metal components of the screw On the carbon composite rod in particular carbon particles as Abrasion generated in the region of the stabilization device thus remain in the body.
Die Erfindung zielt daher darauf ab, unter Überwindung der zuvor geschilderten Schwierigkeiten eine Vorrichtung zur dorsalen Stabilisierung der thorakolumbalen Wirbelsäule der eingangs genannten Art bereit zu stellen, bei welcher sich abbriebbedingte Schwierigkeiten, insbesondere Fremdkörperreaktionen, vermeiden lassen.The The invention therefore aims at overcoming the previously described difficulties a device for dorsal Stabilization of the thoracolumbar spine of the beginning to provide this type, in which abbriebbedingte Difficulties, especially foreign body reactions, avoid to let.
Nach der Erfindung wird hierzu eine Vorrichtung zur dorsalen Stabilisierung der thorakolumbalen Wirbelsäule mit wenigstens einer polyaxialen oder monoaxialen, in das Wirbelpedikel eiangebrachten Schraube, vorzugsweise aus Titan, an deren Kopf eine Klemmschraube vorgesehen ist, bereitgestellt, welche einen eingelegten Carbon-Composite-Stab mittels Klemmen fixiert. Diese Vorrichtung zeichnet sich nach der Erfindung dadurch aus, dass wenigstens am Klemmbereich von Klemmschraube und Carbon-Composite-Stab eine abriebfeste Materialschicht vorgesehen ist. Durch diese abriebfeste Materialschicht werden die mechanischen Eigenschaften der gesamten Vorrichtung nicht verändert, sondern lediglich im Klemmbereich die Oberfläche des Carbon-Composite-Stabes vor zu Abrieb führenden Reibungserscheinungen geschützt. Hierbei bleibt die Fixierung mittels der Klemmpassung der Klemmschraube sichergestellt, die Röntgentransparenz des Caron-Composite-Stabes bleibt erhalten, und die mechanischen Vorteile des Carbon-Materials als Implantat werden nicht beeinträchtigt. Die abriebfeste Materialschicht sorgt lediglich dafür, insbesondere ab riebbedingte Fremdkörperreaktionen im Bereich der implantierten Vorrichtung zu vermeiden.To The invention is for this purpose a device for dorsal stabilization the thoracolumbar spine with at least one polyaxial or monoaxial screw introduced into the vertebral pedicle, preferably made of titanium, provided at the head with a clamping screw is provided which an inserted carbon composite rod by means of Fixed clamps. This device is characterized by the invention characterized in that at least on the clamping region of clamping screw and carbon composite rod an abrasion resistant material layer is provided. By this abrasion-resistant Material layer will be the mechanical properties of the whole Device not changed, but only in the terminal area the surface of the carbon composite rod before to abrasion protected against signs of friction. in this connection remains the fixation by means of the clamping fit of the clamping screw ensured the X-ray transparency of the Caron composite rod remains intact, and the mechanical advantages of the carbon material as an implant are not affected. The abrasion-resistant material layer only provides, especially from rubbing-induced foreign body reactions in the area of the implanted device.
Als besonders geeignete Materialien für die abriebfeste Materialschicht haben sich Titan, Titan-Legierungen, Titan-Aluminium-Legierungen, Edelstahl, Tantal, Tantal-Legierungen, Silikon, Kunststoff, insbesondere Polyethylen, oder Kombinationen hiervon erwiesen.When particularly suitable materials for the abrasion-resistant material layer have titanium, titanium alloys, titanium-aluminum alloys, stainless steel, Tantalum, tantalum alloys, silicone, plastic, especially polyethylene, or combinations thereof.
Gemäß einer bevorzugten Ausgestaltungsform ist die abriebfeste Materialschicht in Form einer Hülse ausgebildet, welche auf den Carbon-Composite-Stab vorzugsweise aufgeschoben und dort kraftschlüssig fixiert wird. Diese Hülse, welche somit teilweise die Oberfläche des Carbon-Composite-Stabes im Klemmbereich abdeckt, bildet an diesen vorbestimmten Stellen der Vorrichtung eine wirksame schützende Hülse gegen Abrieb.According to one preferred embodiment is the abrasion resistant material layer formed in the form of a sleeve, which on the carbon composite rod preferably postponed and fixed there non-positively becomes. This sleeve, which thus partially the surface covering the carbon composite rod in the clamping area, forms on this predetermined locations of the device an effective protective Sleeve against abrasion.
Zusammenfassend ist es bei der erfindungsgemäßen Vorrichtung zur dorsalen Stabilisierung der thorakolumbalen Wirbelsäule zu Vermeidung von Abrieb, insbesondere von Kohlenstoffpartikeln, wesentlich, dass eine abriebfeste Materialschicht wenigstens an den Klemmbereichen von Schraube und Carbon-Composite-Stab vorgesehen wird. Hierdurch lassen sich in wirksamer Weise Fremdkörperreaktionen an den Endoprothesenoberflächen unterdrücken.In summary it is in the inventive device for dorsal stabilization of the thoracolumbar spine to avoid abrasion, in particular of carbon particles, essential that an abrasion resistant material layer at least provided the clamping areas of screw and carbon composite rod becomes. This effectively removes foreign body reactions at the Endoprothesenoberflächen suppress.
Die Erfindung wird nachstehend unter Bezugnahme auf die beigefügte Zeichnung an Hand eines nicht beschränkenden bevorzugten Ausführungsbeispiels näher erläutert. Darin zeigt:The Invention will be described below with reference to the attached Drawing on the basis of a non-limiting preferred Embodiment explained in more detail. It shows:
