Description
Spiralbohrer für zahnärztliche Zwecke. Vorliegende Erfindung betrifft einen, Spiralbohrter für den Gebrauch in zaihnärztlichen Instituten zum Bohren -des NervIcanals eines Zahnes. Bei den zur Zeit in Ge-brauch befindliehen Spiralbohrernbestebt die große:Gefähr ihres Abbrechens und Steckenbleihens im ervkanal sowie auch des Ambohrens, ja -N 1 so gar Durchbohrens der Wurzelwand des Zahnes.Twist drills for dental purposes. The present invention relates to a twist drill for use in dental institutes for drilling the nerve canal of a tooth. In the presently need Ge befindliehen in Spiralbohrernbestebt the great: endanger its breaking up and insert lead absorption in ervkanal as well as the Ambohrens, yes -N 1 so even puncture the root of the tooth wall.
Diese Übelstände mit ihren unliebsamen Folgeerscheinungen beseitigt die Erfindung, indem sie durch Einschaltung einer gewickelten Feder zwischen Kopf und Schaft -des Bohrers die Wirkung außerordenflicher Biegsamkeit und Anschmiegefählgkeit erzeugt, die so weit geht, daß der Kanal sozusagen die Führung des Bohrers -übernimmt. Dadurch hört u;unmehr die krampfhafte Haltung des Hand- oder Winkelstückes auf; das Durchbohren der Würzelwand, das Abbrechen und. Steckenbleiben des Bohrers im Kanal fällt bei ,einigermaßen geschickter Handhabung fort. Auch wird das unangenehme Gefühl der Erschütterung ödes Patienten, hervorgerufen durch die Arbeit mitdiem steifen Bohrer, hier erheblich gemildert.The invention eliminates these inconveniences with their unpleasant consequences by interposing a coiled spring between the head and shaft of the drill to produce the effect of extraordinary flexibility and snugness, which goes so far that the channel, so to speak, takes over the guidance of the drill. As a result, the convulsive posture of the handpiece or angle piece ceases; piercing the root wall, breaking off and. Sticking of the drill bit in the channel f at like everything, fairly swift handling continued. The uncomfortable feeling of shaking the dreary patient, caused by working with the stiff drill, is considerably alleviated here.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt und zwar zeigt Abb. i den, Bohrer in ggebogener Lage und ir- durch StricMinlen markierter Ruhestellung Abb. 2 die #d"riei Einzelteile des Bohrers, Schaft, Feder und Kopf.An exemplary embodiment of the invention is shown in the drawing namely Fig. i shows the drill in a bent position and marked ir- by StricMinlen Rest position Fig. 2 the individual parts of the drill, shaft, spring and head.
Die Erfindung besteht im wesentlichen aus der elastischen Verbindung des Schaftes a und,des Kopfes c mittels der gewickelten Feder b. Der Schaft zeigt zur Eriielung eines festen Aufsitzenis 4-er Feder b an dem oberen Ende eine abgesetzte Verjüngung a." eben-so das untere Ende des Biohrkopfes, eine solche c,. Nach, Einsetzen der Feder wer(den ihre beiden Enden mit den abgesetzten Teilen !des Schaftes und des Kopfes verlötet. Durch die Zw!-schenschaltung der Feder erhält der Bohrer eine außerordentliche Biegsamkeit nach allen Seiten.The invention consists essentially of the elastic connection of the shaft a and the head c by means of the coiled spring b. The shaft shows a stepped taper a at the upper end in order to achieve a firm seat b Separate parts! of the shaft and the head are soldered. The interposition of the spring gives the drill extraordinary flexibility in all directions.
