Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Erzeugung eines Hohlraums für die Aufnahme eines Implantats in Knochengewebe, insbesondere für die Aufnahme eines aneinander grenzende Knochen eines Gelenks verbindenden Implantats.The The invention relates to a device for generating a cavity for the Inclusion of an implant in bone tissue, in particular for recording a contiguous bone connecting a joint implant.
Zum Beispiel werden die das Sprunggelenk bildenden Knochen in bestimmten Fällen durch ein Knochenimplantat miteinander verbunden, das für ein Zusammenwachsen dieser Knochen und damit für eine gewünschte Versteifung des Sprunggelenks sorgt. Das Knochenimplantat wird z. B. dem Beckenknochen oder der Tibia entnommen. Nach Freilegung der genannten Knochen am Gelenkspalt wird der das Implantat aufnehmende Hohlraum durch ein Bohrwerkzeug gebildet.To the An example will be the bones forming the ankle in particular make connected by a bone implant, for a growing together this bone and thus for a desired one Stiffening of the ankle ensures. The bone implant is z. B. the pelvic bone or tibia removed. After exposure of the said bone at the joint space is the implant receiving Cavity formed by a drilling tool.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche die Bildung von Hohlräumen für die Aufnahme von Implantaten in Knochengewebe erleichtert.Of the Invention has for its object to provide a device which the formation of cavities for the Facilitation of implants in bone tissue easier.
Die diese Aufgabe lösende Vorrichtung nach der Erfindung ist gekennzeichnet durch eine am Knochengewebe anbringbare Führung für ein den Hohlraum schaffendes Werkzeug, welche Durchgänge für mehrere, ins Knochengewebe zu treibende Befestigungsstränge aufweist, wobei die Befestigungsstränge die Führung auf ihrer dem Knochengewebe abgewandten Seite unter formschlüssiger Verbindung der Führung mit dem Knochengewebe hintergreifen.The solving this task Device according to the invention is characterized by an am Bone tissue attachable guide for a the cavity creating tool, which passes for several, into the bone tissue to be driven fastening strands having the fastening strands guide the bone tissue on it opposite side under positive Connection of the leadership engage behind with the bone tissue.
Vorteilhaft ermöglicht es die Führung, exakt bemessene Hohlräume zu schaffen, deren Abmessungen genau den Werkzeugabmessungen entsprechen. Insbesondere eine hülsenförmige Führung kann z. B. das Schlagen eines Bohrwerkzeugs verhindern. Es wird nur die unbedingt notwendige Menge an Gewebe abgetragen. Vorteilhaft stabilisieren die in das Knochengewebe eingetriebenen Befestigungsstränge den um den Hohlraum umliegenden Knochengewebebereich.Advantageous allows it's the leadership, exactly sized cavities to create whose dimensions correspond exactly to the tool dimensions. In particular, a sleeve-shaped guide can z. B. prevent the hitting a drill. It will only be the absolutely necessary amount of tissue removed. Advantageously stabilize the in the bone tissue driven fastening strands the around the cavity surrounding bone tissue area.
In einer besonders bevorzugten Ausführungsform der Erfindung hintergreifen die Befestigungsstränge die Führung mit einem abgebogenen Endabschnitt, der vorzugsweise radial nach außen weist. Durch die Abbiegung lässt sich auf besonders einfache Weise eine stabile Verbindung zwischen der Führung und dem Knochengewebe herstellen.In a particularly preferred embodiment invention, the fastening strands engage behind the guide with a bent end section, which preferably points radially outward. By the turn leaves in a particularly simple way a stable connection between the leadership and the bone tissue.
In der Ausführungsform mit einer hülsenförmigen Führung verlaufen die Durchgänge vorzugsweise in axialer Richtung durch die Hülsenwand hindurch und insbesondere parallel zur Hülsenachse. Die durch diese Durchgänge hindurch in das Knochengewebe eingetriebenen Befestigungsstränge bilden eine Art Käfig um den für die Bildung des Hohlraums vorgesehenen Bereich und stabilisieren den Hohlraum.In the embodiment run with a sleeve-shaped guide the passages preferably in the axial direction through the sleeve wall and in particular parallel to the sleeve axis. The through these passages through into the bone tissue driven fastening strands form a kind of cage around the for the formation of the cavity provided area and stabilize the cavity.
Vorzugsweise verteilen sich die Durchgänge gleichmäßig über den Umfang der Hülse, so dass ein Käfig mit gleichmäßigen Gitterabständen gebildet ist.Preferably the passages distribute themselves evenly over the Circumference of the sleeve, leaving a cage formed with uniform grid spacing is.
Vorzugsweise bestehen die Befestigungsstränge aus Drähten, deren dem Knochengewebe zugewandten Enden angespitzt sind.Preferably consist of the fastening strands made of wires, their ends facing the bone tissue are sharpened.
In weiterer Ausgestaltung der Erfindung ist ein die Führung ausrichtendes Kernelement vorgesehen, das vor der Befestigung der Führung am Knochengewebe am Knochengewebe angebracht wird. Die Führung kann auf dieses Kernelement dann aufgesteckt werden, das im Falle einer hülsenförmigen Führung zylindrisch ausgebildet ist.In Another embodiment of the invention is a guiding the aligning Nuclear element provided before the attachment of the guide on Bone tissue is attached to the bone tissue. The leadership can be attached to this core element, in the case of a sleeve-shaped guide cylindrical is trained.
Vorzugsweise steht das Kernelement auf der dem Knochengewebe abgewandten Seite der Führung von der Führung vor, so dass es nach Befestigung der Führung am Knochengewebe an dem vorstehenden Ende aus der Führung herausgezogen werden kann.Preferably the core element is on the side facing away from the bone tissue the leadership from the leadership before, so that it after attachment of the guide to the bone tissue on the protruding end of the guide can be pulled out.
Vorzugsweise weist das Kernelement einen Durchgang, insbesondere einen zentralen Durchgang, für einen am Knochengewebe zu befestigenden Strang auf.Preferably the core element has a passage, in particular a central one Passage, for a strand to be attached to the bone tissue.
Dieser Strang lässt sich insbesondere in den Gelenkspalt eines Gelenks eintreiben, dessen an den Gelenkspalt grenzende Knochen durch das Implantat miteinander verbunden werden sollen. An dem Strang ist dann das Kernelement geführt und gehalten, während die Führung durch das Kernelement ausgerichtet wird.This Strand leaves in particular, drive into the joint space of a joint whose Bone adjacent to the joint space through the implant to be connected. At the strand is then the core element guided and held while the leadership is aligned by the core element.
