Abstract
Description
Die Erfindung betrifft eine ostesynthetisches System, bestehend aus einer Platte mit mehreren, ein Innengewinde aufweisenden Löchern und Knochenschrauben, die in den Frakturstücken des Knochens und in der Platte eingeschraubt werden.The invention relates to an east synthetic system, consisting of a plate with several, with an internal thread holes and bone screws that are in the fracture pieces of the bone and in the Plate are screwed in.
Aus der Beschreibung des
Der Efindung lag die Aufgabe zugrunde, ein Implantat zu konstruieren, das traumabedingte Fehlstellungen oder Defekte versorgen kann. Es ist hierbei ein steifes System gefordert, welches in der Lage ist, auch Defektstellen zu überbrücken und sicher zu fixieren.The invention was based on the task to construct an implant, the trauma-related malposition or can supply defects. A rigid system is required which is able to bridge defects and fix them securely.
Die Aufgabe wird erfindungsgemäß entsprechend den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen der Efindung sind in den Unteransprüchen angegeben.The task is according to the invention accordingly solved the features of claim 1. Appropriate configurations of the invention are in the subclaims specified.
Erfindungsgemäß wird eine osteosynthetische Druckplatte geschaffen, mit der es möglich ist, die Lage von Frakturstücken eines Knochens zu korrigieren bzw. die Beweglichkeit zweier oder mehrerer Frakturstücken zueinander zu unterbinden. Die osteosynthetische Platte besitzt mehrere Löcher zur Aufnahme von Knochenschrauben, welche beim Befestigen der Platte zu einer winkelstabilen kraftschlüssigen Verbindung führt.According to the invention is an osteosynthetic Pressure plate created, with which it is possible to determine the location of fracture pieces Correct bone or the mobility of two or more fracture pieces to each other to prevent. The osteosynthetic plate has several holes for Bone screws, which are used when attaching the plate leads to an angularly stable non-positive connection.
Die Knochenschrauben weisen am Schraubenkopf oder -hals Gewinde auf, welche in entsprechend ausgestaltete Gewinde in den Löchern der Druckplatte eingeschraubt werden. Erfindungsgemäss wird ein sphärisches oder ovales Gewinde verwendet, d.h., ein Aussengewinde auf einem Kugelsegment der Schraube und ein entsprechendes Innengewinde in der Druckplatte.The bone screws point to the screw head or neck thread on, which in appropriately designed threads in the holes the pressure plate. According to the invention a spherical or oval thread, i.e. an external thread on one Ball segment of the screw and a corresponding internal thread in the pressure plate.
Ebenfalls können aber auch Schrauben verwendet werden, die am Schraubenkopf oder-hals eine glatte Aussenoberfläche aufweisen, deren Kontur mit der Innenkontur der Druckplattenlöcher übereinstimmt, so dass beim Einschrauben der Knochenschrauben der Schraubenkopf oder -hals an der Innenkontur des Druckplattenloches anliegt.Screws can also be used that have a smooth outer surface on the screw head or neck, whose contour matches the inner contour of the pressure plate holes, so when screwing in the bone screws the screw head or neck against the inner contour of the pressure plate hole.
In vorteilhafter Weise sind die Löcher symmetrisch in der Plattenlängsrichtung angeordnet, wobei natülich eine unsymmetrische Anordnung der Löcher nicht ausgeschlossen werden soll.The holes are advantageously symmetrical in the longitudinal direction of the plate arranged, of course an asymmetrical arrangement of the holes can not be excluded should.
Besonders vorteilhaft kann für jedes der zu verbindenden Knochenbruchstücke jeweils eine Gruppe von Löchern in den Eckpunkten eines Dreieckes angeordnet sein.Can be particularly advantageous for everyone each of the bone fragments to be joined is a group of holes be arranged in the corner points of a triangle.
Die Gewindesteigungen des Knochengewindes des Schraubenschaftes und des Gewindes des Schraubenkopfes oder des Schraubenhalses sind derart ausgeführt, dass es zu einer Kompression zwischen der Platte und den Knochenstücken beim Einschrauben der Schrauben in die Platte und in die Knochenstücke kommt.The thread pitches of the bone thread the screw shaft and the thread of the screw head or of the screw neck are designed so that there is a compression between the plate and the bone pieces when screwing in the Screws into the plate and into the bone pieces.
Die sphärische oder ovale innere Form des Innengewindes der Platte entspricht der sphärischen oder ovalen Außenform einer Knochenschraube im Bereich des Schraubenkopfes oder des Schraubenhalses. Wenn der Schraubenkopf ohne Gewinde ausgeführt ist, liegt dieser mit seiner glatten Aussenwandung auf den die sphärische oder ovale innere Form bildenden Gewindespitzen des Innengewindes an.The spherical or oval inner shape the internal thread of the plate corresponds to the spherical or oval outer shape a bone screw in the area of the screw head or the screw neck. If the screw head is without thread, it lies with his smooth outer wall on which the spherical or oval inner shape forming thread tips of the internal thread.
Eine günstige Ausgestaltung der Erfindung liegt darin, dass die Gewindelänge der Knochenschraube im Bereich des Schraubenkopfes oder des Schraubenhalses im wesentlichen der Dicke der Platte entspricht.A favorable embodiment of the invention lies in that the thread length the bone screw in the area of the screw head or the screw neck corresponds essentially to the thickness of the plate.
Zum Einschrauben weisen die Knochenschrauben einen Kreuzschlitz, Innensechskant oder Innenstern auf.The bone screws have to be screwed in a cross recess, hexagon socket or inner star.
Die Konstruktion und die Wirkung der einzelnen Komponenten der erfindungsgemäßen osteosynthetischen Druckplatten werden im folgenden anhand der Zeichnungen erläutert.The construction and the effect of the individual components of the osteosynthetic printing plates according to the invention are explained below with reference to the drawings.
