Titel: Knochenchirurgische HaltevorrichtungTitle: Bone surgical holding device
BeschreibungDescription
Die Erfindung betrifft eine knochenchirurgische Haltevorrichtung für einen Fixierstab.The invention relates to a bone surgical holding device for a fixation rod.
Derartige Haltevorrichtungen sind in einer Vielzahl bekannt. Nachteilig bei diesen Haltevorrichtungen ist die bauliche Höhe sowie die Vielzahl der Einzelteile, die bei einer Operation unerwünscht sind.A large number of such holding devices are known. The disadvantage of these holding devices is their structural height and the large number of individual parts that are undesirable during an operation.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach handhabbare Haltevorrichtung bereitzustellen, die eine geringe Bauhöhe aufweist.The invention is based on the object of providing an easy-to-handle holding device which has a low overall height.
Diese Aufgabe wird bei einer Vorrichtung gemäß dem Hauptanspruch gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Uiyteransprüchen.This object is achieved by a device according to the main claim. Advantageous further developments emerge from the dependent claims.
In der Zeichnung ist eine bevorzugte Ausführungsform dargestellt. Dabei stellt die Figur eine Draufsicht auf die Knochenplatte mit Aufnahmevorrichtung für den Fixierstab dar, wobei die Figuren 2 und 3 entsprechende Schnitte II-II und III-III gemäß Figur 1 zeigt. Die Figur 4 zeigt Ankerstifte der Knochenplatte. Die Figur 6 zeigt eine Seitenansicht der als Deckel ausgebildeten Fixiereinrichtung für den Fixierstab, die Figur 5 zeigt eine Ansicht der Unterseite und die Figur 7 zeigt eine Draufsicht auf die Oberseite der Fixiereinrichtung.A preferred embodiment is shown in the drawing. The figure shows a top view of the bone plate with the receiving device for the fixing rod, with Figures 2 and 3 showing corresponding sections II-II and III-III according to Figure 1. Figure 4 shows anchor pins of the bone plate. Figure 6 shows a side view of the fixing device designed as a cover for the fixing rod, Figure 5 shows a view of the underside and Figure 7 shows a top view of the top of the fixing device.
Aus den Figuren ist deutliche erkennbar, daß das Schwenklager, das aus den Lagerteilen 1 und 2 besteht, mit einem Lagerauge 3 versehen ist. Der an der Knochenplatte bzw. Aufnahmevorrichtung 4 vorgesehene Teil des Lagers 1 ist ebenfalls mit einem Lagerauge 5 versehen. Durch die beiden Lageraugen 3 und 5 ist ein Bolzen einführbar. In einer Aufnahmevorrichtung 6 ist eine Schraube unverlierbar befestigbar, über die die Fixiereinrichtung 7 an der Knochenplatte 8 durch Eindrehen der Schraube in ein Gewinde 9 befestigbar ist. Dabei kann ein Fixierstab in der Aufnahmevorrichtung 4 festgeklemmt werden.It is clearly evident from the figures that the pivot bearing, which consists of the bearing parts 1 and 2, is provided with a bearing eye 3. The part of the bearing 1 provided on the bone plate or receiving device 4 is also provided with a bearing eye 5. A bolt can be inserted through the two bearing eyes 3 and 5. A screw can be captively fastened in a receiving device 6, via which the fixing device 7 can be fastened to the bone plate 8 by screwing the screw into a thread 9. A fixing rod can be clamped in the receiving device 4.
Ferner ist erkennbar, daß seitlich neben dem Lager 1 ein Schraubenlager 10 für einen versenkbaren Schraubenkopf vorgesehen ist,- wobei über diese Schraube die Knochenplatte 8 am Knochen befestigbar ist. An der diagonal gegenüberliegenden Seite ist ein weiteres Schraubenlager zur Aufnahme einer weiteren Knochenschraube vorgesehen. Markant an der erfindungsgemäßen knochenchirurgischen Haltevorrichtung ist die geringe Bauhöhe sowie das Merkmal, daß neben den beiden Knochenschrauben zum Fixieren der Haltevorrichtung am Knochen kein weiteres Bauteil benötigt wird. Alle erforderlichen Bauteile sind unverlierbar miteinander verbunden.It can also be seen that a screw bearing 10 for a retractable screw head is provided on the side next to the bearing 1, whereby the bone plate 8 can be fastened to the bone using this screw. On the diagonally opposite side, another screw bearing is provided to accommodate another bone screw. A striking feature of the bone surgical holding device according to the invention is its low overall height and the feature that no other component is required apart from the two bone screws for fixing the holding device to the bone. All of the necessary components are connected to one another in a captive manner.
