Description

Platteplate

ll(j i (In r Utirplat &Igr;&igr;&igr;&eegr;&eegr; im Horn ich dc; r Ui rim lnäuln werden dünne Platten eingesetzt, durch die Schrauben h i ndu rcticje füh r L sind, die die Verbindung zwisclien dem Knochenmaterial und der Platte sicherstellen. Häufig sind die Platten a in B &eegr; h rungsrand mit geringen &Ggr; äsen vergehen, um den Schraubenkopf aufzunehmen. Bewegungen der Wirbelsäule bewirken in vielen Tollen, daß der Schraubenkopf und die Fase sich wie ein (Gelenk verhalten, da eine führung des Schraubenhai ses wegen der geringen Platte &eegr;stärke der Platte nicht erfolgen kann.In the Utirplat '&igr;&igr;&eegr;&eegr; in the horn and in the neck, thin plates are inserted through which screws are passed, which ensure the connection between the bone material and the plate. The plates are often made of a beveled edge with small notches to accommodate the screw head. In many cases, movements of the spine cause the screw head and the bevel to behave like a joint, since the screw head cannot be guided due to the thin plate thickness.

Aufgabe der Erfindung ist es, die Platte der eingangs genannten Art so auszubilden, daß eine einwandfreie führung der Schrauben gewährleistet ist und eine Versteifung der Platten e r &Ggr; &ogr; 1 c] I .The object of the invention is to design the plate of the type mentioned at the beginning in such a way that a perfect guidance of the screws is ensured and a stiffening of the plates e r Γ γ 1 c] I .

Gelöst wird diese Aufgabe erfindungsgemäfl dadurch, daO den &Pgr; oh runge &eegr; jeweils die Schrauben auf einem Teil i lirer Länge umfassende Hülsen zugeordnet sind, die sich von der Unterseite der Platte aus erstrecken und mit ihrem einen Ende fest mit der Platte verbunden sind.This object is achieved according to the invention in that the Π oh runge η are each assigned sleeves which enclose the screws over a portion of their length, which extend from the underside of the plate and are firmly connected to the plate at one end.

Diese &Ggr;&Igr; ü 1 &pgr; e &eegr; führen einerseits dazu, daß insgesamt die Platte steifer wird und darüber hinaus geben sie den Schrauben eine Führung, so daß die Schraube sich in der Platte nicht mehr in der Art eines Gelenkes bewegen kann.These Γλ ü 1 π e �eegr; lead on the one hand to the plate becoming stiffer overall and, in addition, they provide the screws with a guide so that the screw can no longer move in the plate like a joint.

Die Erfindung soll anhand der schematischen Darstellung erläutert werden, wobei die Figur 1 eine Aufsicht auf die Platte und Figur 2 einen Schnitt durch die Platte mit eingesetzter Schraube zeigt.
Im einzelnen ergibt sich aus der Figur 1, daß in der PlatteThe invention will be explained with reference to the schematic representation, wherein Figure 1 shows a plan view of the plate and Figure 2 shows a section through the plate with the screw inserted.
In detail, Figure 1 shows that in the plate

(4) mehrere Bohrungen angeordnet sind, wobei diese mit (1) bezeichnet wurden.(4) several holes are arranged, which are designated with (1).

Aus der Figur 2 ist ersichtlich, daß das Material der Platte sehr dünn ist, so daß bei eingesetzter Schraube (2) aufgrund der Ausbildung des Schraubenkopfes eine Winke1 bewegung der Schraube in bezug auf die Platte möglich ist, d.h. es bildet sich hier eine Art Gelenk. Erfindungsgemäß sind nun an der Platte Hülsen (3) angeordnet, die die Schrauben (2) auf einem Teil ihrer Länge umgeben. Diese Hülsen (3) sind fest mit der Platte verbunden. Die Figur 2 läßt erkennen, daß durch diese Hülsen die Schraube (2) keine Möglichkeit mehr hat zu einer Winkelbewegung, bezogen auf die Platte (4),obwohl das Plattenmaterial selbst in seiner Stärke unverändert geblieben ist. Insgesamt erhöhen diese Hülsen auch die Steifigkeit der gesamten Plattenausbildung. Die für das Einsetzen der Platte, insbesondere der HülsenFrom Figure 2 it can be seen that the material of the plate is very thin, so that when the screw (2) is inserted, the design of the screw head allows an angular movement of the screw in relation to the plate, i.e. a kind of joint is formed here. According to the invention, sleeves (3) are now arranged on the plate, which surround the screws (2) over part of their length. These sleeves (3) are firmly connected to the plate. Figure 2 shows that these sleeves mean that the screw (2) no longer has the possibility of an angular movement in relation to the plate (4), even though the thickness of the plate material itself has remained unchanged. Overall, these sleeves also increase the rigidity of the entire plate structure. The dimensions required for inserting the plate, in particular the sleeves

(5) notwendige größere Bohrung im Kopf spielt gegenüber den Vorteilen, die sich aus dieser Art der Verplattung ergeben, keine Rolle.(5) The need for a larger hole in the head is irrelevant compared to the advantages resulting from this type of plating.
