Description

-2-Beschreibung: -2-Description:

In der Zahnmedizin werden zur Aufbereitung von Wurzelkanälen feine nadelartige Werkzeuge verwendet. Diese können bei Überlastung brechen und den Wurzelkanal obliterieren.In dentistry, fine needle-like tools are used to prepare root canals. These can break if overloaded and obliterate the root canal.

Sinn der Erfindung ist es diese abgebrochenen Reste möglichst einfach zu entfernen.The purpose of the invention is to remove these broken remains as easily as possible.

Dies geschieht mittels einer konfektionierten Hohlnadel, wie sie für Spritzen verwendet werden in beliebiger erforderlicher Größe, die über das frakturierte Ende geschoben werden kann. In der Nadel befindet sich ein entsprechend feines konisches Wurzelkanal instrument, zunächst fixiert durch eine dauerelastische Masse wie Silikon-Kautschuk, das soweit vorgeschoben wird, bis eine so starke Klemmwirkung entsteht, daß der frakturierte Rest aus dem Wurzelkanal gezogen werden kann. Eine schraubenförmig gestaltete Oberfläche der Spitze oder einseitige Anfasung erhöht die erzielbare Klemmwirkung.This is done using a prefabricated hollow needle, such as those used for syringes, in any required size, which can be pushed over the fractured end. The needle contains a correspondingly fine, conical root canal instrument, initially fixed by a permanently elastic mass such as silicone rubber, which is pushed forward until a clamping effect is so strong that the fractured residue can be pulled out of the root canal. A screw-shaped surface of the tip or a one-sided chamfer increases the achievable clamping effect.
