"Qsteosyntheseplatte""Qsteosynthesis plate"

Die Neuerung bezieht sich auf eine Osteosyntheseplatte gemäß dem Oberbegriff des Hauptanspruches.The innovation relates to an osteosynthesis plate according to the preamble of the main claim.

üblicherweise aus Metall bestehende Osteosyntheseplatten dienen zur Fixierung von Knochensegmenten und sind mit Aufnahmebohrungen versehen, durch die sogenannte Knochenschrauben geführt werden können, die die Osteosyntheseplatte an den Knochen festlegen .
10
Osteosynthesis plates, usually made of metal, are used to fix bone segments and are provided with holes through which so-called bone screws can be passed, which fix the osteosynthesis plate to the bone.
10

Komplizierte SpI i tterbrliche machen es erforderlich, daß die einzelnen Bruchfragmente vor ihrer endgültigen Festlegung mittels Platte über Fixierdrähte ("Kirschner-Drähte") in ihrer gewünschten Stellung festgelegt werden, bevor die eigentliche Osteosyntheseplatte angebracht wird. Diese Fixierdrähte stehen weit nach außen vor und stören häufig die ordnungsgemäße Anordnung der eigentlichen Osteosyntheseplatte.Complicated splinter fractures require that the individual fracture fragments be fixed in their desired position using fixation wires (“Kirschner wires”) before they are finally fixed using a plate and the actual osteosynthesis plate is attached. These fixation wires protrude far outwards and often interfere with the correct positioning of the actual osteosynthesis plate.

Der Neuerung liegt die Aufgabe zugrunde, die Osteosynthesepl atte so auszubilden, daß sie trotz vorstehender Fixierdrähte in der gewünschten Stellung am Knochen festgelegt werden kann.The innovation is based on the task of designing the osteosynthesis plate in such a way that it can be fixed in the desired position on the bone despite protruding fixation wires.

Diese der Neuerung zugrundeliegende Aufgabe wird dadurch gelöst, daß in der Osteosyntheseplatte sogenannte Fixierbohrungen vorgesehen sind, die über die Osteosyntheseplatte verteilt eine provisorische Festlegung der Osteosyntheseplatte an den Fixierdrähten ermöglicht, d. h. andersherum ausgedrückt,This task underlying the innovation is solved by providing so-called fixation holes in the osteosynthesis plate, which are distributed over the osteosynthesis plate and enable a provisional fixation of the osteosynthesis plate to the fixation wires, i.e., expressed the other way round,

daß die vorstehenden Fixierdrähte die beliebige Ausrichtung der Osteosyntheseplatte dadurch nicht behindern, daß in der Osteosyntheseplatte Fixierbohrungen vorgesehen sind, durch die die überstehenden Fixierdrähte geführt werden können. Die Fixierbohrungen weisen natürlich einen wesentlichen kleineren Durchmesser als die Aufnahmebohrungen für die Knochenschrauben auf, wobei beispielsweise der Durchmesser der Fixierbohrungen 1,6 mm betragen kann.that the protruding fixation wires do not hinder the alignment of the osteosynthesis plate as there are fixation holes in the osteosynthesis plate through which the protruding fixation wires can be guided. The fixation holes naturally have a much smaller diameter than the holes for the bone screws, whereby the diameter of the fixation holes can be 1.6 mm, for example.

Es wird weiterhin vorgeschlagen, daß die Fixierbohrungen nur im Bereich der äußeren Kanten der Osteosyntheseplatte vorgesehen sind. Durch eine solche Anordnung wird erreicht, daß eine Schwächung der eigentlichen Osteosyntheseplatte durch die Vielzahl der Fixierbohrungen nicht eintritt.It is also suggested that the fixation holes are only provided in the area of the outer edges of the osteosynthesis plate. Such an arrangement ensures that the actual osteosynthesis plate is not weakened by the large number of fixation holes.

Ein Ausführungsbeispiel der Neuerung wird nachfolgend anhand der Zeichnungen erläutert.An example of the innovation is explained below using the drawings.

Die Zeichnung zeigt eine Osteosyntheseplatte 1, die mit Aufnahmebohrungen 2 für in der Zeichnung nicht dargestellte Knochenschrauben ausgerüstet ist.The drawing shows an osteosynthesis plate 1, which is equipped with receiving holes 2 for bone screws not shown in the drawing.

Im äußeren Umfangsbereich der Osteosyntheseplatte 1 sind Fixierbohrungen 3 vorgesehen, die einen wesentlich kleineren Durchmesser als die Aufnahmebohrungen 2 für die Knochenschrauben aufweisen, wobei dieser Durchmesser der Fixierbohrungen 3 beispielsweise 1,6 mm betragen kann.In the outer peripheral area of the osteosynthesis plate 1, fixing holes 3 are provided which have a significantly smaller diameter than the receiving holes 2 for the bone screws, whereby this diameter of the fixing holes 3 can be, for example, 1.6 mm.

Es ist ersichtlich, daß es nunmehr möglich ist, die über die Wunde vorstehenden Fixierdrähte durch die eine oder andere Fixierbohrung 3 hindurchzuführen,It is clear that it is now possible to guide the fixing wires protruding above the wound through one or the other fixing hole 3,

so daß dadurch eine korrekte Lage der Osteosynthese· platte gewährleistet wird, ohne daß diese korrekte Lage durch die Fixierdrähte gestört wird.so that a correct position of the osteosynthesis plate is ensured without this correct position being disturbed by the fixation wires.
