Ein Zwischenwirbelimplantat, welches eine axiale durchgängige Öffnung mit drei seitlichen Durchbrüchen aufweist, ist aus der Offenlegungsschrift US 2003/0028249 A bekannt. Auch hier ist der Halt für pastöse Füllstoffe nur ungenügend und erschwert die Operationstechnik.One Intervertebral implant, which has an axial through opening three lateral breakthroughs is known from the publication US 2003/0028249 A. Again, the stop is for pasty fillers only insufficient and complicates the surgical technique.
Demgemäß liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Zwischenwirbelimplantat bereitzustellen, dass für Füllstoffe, insbesondere pastöse Füllstoffe, einen ausreichenden Halt bietet.Accordingly, lies The object of the present invention is to provide an intervertebral implant, that for fillers, especially pasty fillers, provides a sufficient grip.
Diese Aufgabe wird durch ein Zwischenwirbelimplantat mit den Merkmalen des Anspruchs 1 gelöst. Demgemäß weist ein Zwischenwirbelimplantat der eingangs genannten Gattung mindestens ein Halterungselement für den Füllstoff auf, das innerhalb des Hohlkanals angeordnet ist.These Task is performed by an intervertebral implant with the features of claim 1. Accordingly, FIG an intervertebral implant of the type mentioned at least a support element for the filler on, which is arranged within the hollow channel.
Das Vorhandensein des mindestens einen Halterungselementes erlaubt ein gutes Haften von (pastösen) Füllstoffen in dem genannten Zwischenwirbelimplantat und verhindert ein Herausfallen des Füllstoffs während der Implantation.The Presence of at least one support member allows a good adhesion of (pasty) fillers in said intervertebral implant and prevents it from falling out of the filler while implantation.
In einer vorteilhaften Ausführungsform der Erfindung erstreckt sich der Hohlkanal in bestimmungsgemäßer Lage des Zwischenwirbelimplantates in einer Richtung, die im Wesentlichen parallel zur der durch die Mittelpunkte der dem Zwischenwirbelimplantat benachbarten Wirbelkörper verlaufenden Längsachse der Wirbelsäule, innerhalb des Zwischenwirbelimplantates verläuft.In an advantageous embodiment the invention, the hollow channel extends in the intended position of the intervertebral implant in a direction that is essentially parallel to that through the centers of the intervertebral implant adjacent vertebral bodies extending longitudinal axis The spine, within the intervertebral implant.
Mit besonderem Vorteil ist das mindestens eine Halterungselement eine im Zwischenwirbelimplantat angeordnete Nut, die gemäß einer Variante der Erfindung zumindest teilweise als eine den Hohlkanal umlaufende Nut ausgestaltet ist. Weiterhin ist es möglich, dass die Nut den Hohlkanal gewindeförmig umläuft.With particular advantage is the at least one support element a arranged in the intervertebral implant groove, which according to a Variant of the invention at least partially as a hollow channel circumferential Groove is configured. Furthermore, it is possible that the groove is the hollow channel rotates thread-shaped.
In einer anderen Ausführungsform der Erfindung ist das mindestens eine Halterungselement als Vorsprung des Zwischen wirbelimplantates in Richtung der Mitte des Hohlkanals ausgebildet. Auch die Anordnung einer Reihe von Vorsprüngen in der den Hohlkanal begrenzenden Wandung des Zwischenwirbelimplantates ist vorteilhaft. Im Ergebnis wird so ein guter Halt von (pastösen) Füllstoffen im Implantat erreicht.In another embodiment The invention is the at least one support member as a projection of the intervertebral implant in the direction of the middle of the hollow channel educated. Also, the arrangement of a series of protrusions in the hollow channel limiting wall of the intervertebral implant is advantageous. The result is a good hold of (pasty) fillers reached in the implant.
Selbstverständlich ist es auch denkbar, dass das erfindungsgemäße Zwischenwirbelimplantat sowohl mindestens eine Nut, als auch mindestens einen Vorsprung innerhalb des Hohlkanals als Halterungselement aufweist. Die gemeinsame Verwendung von Nuten und Vorsprüngen kann besonders günstige Auswirkungen auf die Haftung von (pastösen) Füllstoffen im Hohlkanal des Implantats haben.Of course it is it is also conceivable that the intervertebral implant according to the invention both at least one groove, as well as at least one projection having within the hollow channel as a support member. The common Use of grooves and protrusions can be especially cheap Effects on the adhesion of (pasty) fillers in the hollow channel of the Have implant.
Die in der Wandung des mindestens einen Hohlkanals angeordneten Halterungselemente des Zwischenwirbelimplantats sind bevorzugt im Wesentlichen orthogonal zu einer Mittelachse des Hohlkanals angeordnet.The in the wall of the at least one hollow channel arranged mounting elements of the intervertebral implant are preferably substantially orthogonal arranged to a central axis of the hollow channel.
Die in der Wandung des mindestens einen Hohlkanals angeordneten Halterungselemente können auch auf einer Ebene liegen, die im Wesentlichen orthogonal zur Mittelachse des Hohlkanals angeordnet ist, wobei die Mittelachse durch den Mittelpunkt des Hohlkanals des Zwischenwirbelimplantates verläuft. Auch dies hat günstige Auswirkungen auf die Haftung von (pastösen) Füllstoffen im Hohlkanal.The in the wall of the at least one hollow channel arranged mounting elements can also lie on a plane that is substantially orthogonal to the Center axis of the hollow channel is arranged, wherein the central axis through the center of the hollow channel of the intervertebral implant runs. This too has favorable Effects on the adhesion of (pasty) fillers in the hollow channel.
Ebenso kann das im Hohlkanal angeordnete Halterungselement als rauhe Oberfläche der den Hohlkanal bildenden Wandung des Zwischenwirbelimplantates ausgebildet sein. Eine solche rauhe Oberfläche kann z. B. durch Abstrahlung mit Korund erzielt werden. Vorteilhaft ist dabei ein Mittenrauhwert von Ra > 5 μm.Likewise, the holding element arranged in the hollow channel can be designed as a rough surface of the wall of the intervertebral implant forming the hollow channel. Such a rough surface can, for. B. can be achieved by radiation with corundum. An average roughness value of R a > 5 μm is advantageous.
Das erfindungsgemäße Zwischenwirbelimplantat weist zwei im Wesentlichen parallel zueinander verlaufende Sagittalschenkel auf, die jeweils durch einen anterioren, also ventral verlaufenden und einen posterioren, also dorsal verlaufenden Transversalschenkel miteinander verbunden sind. Dabei beziehen sich die Bezeichnungen der Schenkel des erfindungsgemäßen Zwischenwirbelimplantates auf die sich bei bestimmungsgemäßer Verwendung des Implantates ergebende Lage des Zwischenwirbelimplantates im Körper eines Patienten.The Intervertebral implant according to the invention has two substantially parallel sagittal limbs on, each by an anterior, so ventral running and a posterior, ie dorsally extending transversal limb connected to each other. The designations refer to this the leg of the intervertebral implant according to the invention to which, when used as intended of the implant resulting position of the intervertebral implant in body a patient.
Daraus ergibt sich, dass das erfindungsgemäße Zwischenwirbelimplantat eine im Wesentlichen ringförmige Struktur aufweist. Dadurch wird eine optimale Abstützung der benachbarten Wirbel der Wirbelsäule durch das Implantat erreicht.from that shows that the intervertebral implant according to the invention a substantially annular Structure has. This will provide optimal support for the adjacent vertebrae of the spine reached through the implant.
In einer vorteilhaften Ausgestaltung der Erfindung weist das erfindungsgemäße Zwischenwirbelimplantat zwei jeweils in einer transversalen Ebene verlaufende Knochenauflageflächen auf. Diese Knochenauflageflächen, auf denen nach der Einbringung des Implantates in den Körper eines Patienten jeweils einer von zwei in der Wirbelsäule benachbarten Wirbel zu liegen kommt, werden jeweils von den Sagittal- und Transversalschenkeln des Implantates ausgebildet, und zwar jeweils von den im Wesentlichen in einer Transversalebene verlaufenden Seiten dieser Sagittal- und Transversalschenkel. Durch die Knochenauflageflächen wird eine gute Kräfteverteilung gewährleistet.In An advantageous embodiment of the invention comprises the intervertebral implant according to the invention two each in a transverse plane extending bone support surfaces. These bone support surfaces, on which after insertion of the implant into the body of a Each patient to one of two vertebra adjacent in the spine lying comes from each of the sagittal and transversal limbs of the implant, in each case of the substantially in a transverse plane running sides of this sagittal and Transversalschenkel. Due to the bone support surfaces, a good distribution of forces guaranteed.
Um die Haftung des Zwischenwirbelimplantates mit den benachbarten, zu verbindenden Wirbeln der Wirbelsäule zu verbessern, weist mindestens eine der Knochenauflageflächen eine Profilierung auf. Zum gleichen Zweck ist auf mindestens einer der Knochenauflageflächen mindestens ein Verbindungselement, beispielsweise in Form eines Dornes, angeordnet.Around the adhesion of the intervertebral implant to the neighboring, at least to improve vertebral spinal cord connectivity one of the bone support surfaces a profiling on. For the same purpose is on at least one the bone support surfaces at least one connecting element, for example in the form of a Thorn, arranged.
Um dem Operateur das Einbringen des erfindungsgemäßen Zwischenwirbelimplantates zwischen zwei benachbarte Wirbelkörper der Wirbelsäule zu ermöglichen, weist das Zwischenwirbelimplantat ein Kopplungselement in Form einer Bohrung mit Gewinde auf, das dem Einsetzen des Zwischenwirbelimplantates dient. Die Bohrung verläuft in einer bestimmungsgemäßen Lage des Zwischenwirbelimplantates entlang einer sagittalen Achse, wobei diese Bohrung mit besonderem Vorteil mittig in dem anterioren Transversalschenkel des Zwischenwirbelimplantats angeordnet ist.Around the surgeon the introduction of the intervertebral implant according to the invention between allowing two adjacent vertebral bodies of the spine, the intervertebral implant has a coupling element in the form of a Drilled hole on the insertion of the intervertebral implant serves. The hole runs in a proper position of the intervertebral implant along a sagittal axis, wherein this hole with particular advantage in the middle in the anterior transverse limb of the intervertebral implant is arranged.
Mit Hilfe eines Einsetzinstruments, das über ein Haltemittel, z. B. in Form eines Fortsatzes, verfügt, das in die Bohrung eingeführt werden kann, kann der Operateur das erfindungsgemäße Zwischenwirbelimplantat in seine bestimmungsgemäße Lage zwischen zwei Wirbelkörper bringen.With Help of an insertion tool, which has a holding means, for. B. in the form of an extension, has, that introduced into the hole can be, the surgeon, the intervertebral implant according to the invention in its intended location between two vertebral bodies bring.
