Description

Wurzelschraube zum Ausziehen von Zahnwurzeln Die Erfindung betrifft eine Wurzelschraube zum Ausziehen von Zahnwurzeln und besteht darin, daß die Wurzelschraube aus zwei Teilen zusammengesetzt ist, nämlich aus einem in eine Vorschneide endenden konischen Gewindestift und .einem mittels Rutschkupplung mit diesem verbundenen Schaftteil, der sich beim Einschrauben des Gewindestiftes selbsttätig von diesem löst. Die neue Wurzelschraube wird entweder von Hand oder mittels Bohrmaschine durch Hand-oder Winkelstück in die Wurzel reingeführt. Hat die Schraube eine gewisse Tiefe und damit einen gewissen Halt erreicht, so tritt die Rutschkupplung in Tätigkeit, und der Schaftteil löst sich selbständig von dem Gewindestift. Man kann nun den Schaft vom Gewindestift abziehen und den letzteren mit der Wurzel leicht, und zwar ohne jedes Verletzen. des Kiefers oder Zahnfleisches, herausziehen.Root screw for extracting tooth roots The invention relates to a root screw for extracting tooth roots and consists in that the root screw is composed of two parts, namely one ending in a pre-cutting edge conical threaded pin and one connected to it by means of a slip clutch Shank part that is automatically removed from the threaded pin when it is screwed in solves. The new root screw is carried out either by hand or with a drill Hand or contra-angle handpiece inserted into the root. Does the screw have a certain depth and thus a certain hold is reached, the slip clutch comes into action, and the shaft part detaches itself from the threaded pin. You can now Pull off the shaft from the threaded pin and lightly pull the latter with the root, namely without any harm. of the jaw or gums, pull out.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigt Fig. i eine von Hand zu betätigende Wurzelschraube nach der Erfindung in natürlicher Größe, Fig.2 eine mittels Bohrmaschine zu betätigende Wurzelschraube in natürlicher Größe und Fig.3 eine Wurzelschraube nach Fig. 2 in vergrößertem Maßstabe.The subject of the invention is shown in the drawing, for example, namely Fig. i shows a manually operated root screw according to the invention in natural size, Fig. 2 a root screw to be actuated by means of a drill in natural size and FIG. 3 a root screw according to FIG. 2 on an enlarged scale.

Auf der Zeichnung ist i der Schaftteil der neuen Wurzelschraube, der durch die Rutschkupplung q. mit dem mit Gewinde 3 versehenen konischen Gewindestift 2 verbunden ist.On the drawing i is the shaft part of the new root screw, the through the slip clutch q. with the conical threaded pin provided with thread 3 2 is connected.
