Description

Instrumentenhalter für rotierende medizinische Instrumente. Die Erfindung betrifft einen Instrumentenhalter für rotierende medizinische Instrumente, welcher an einer biegsamen Welle, die ihrerseits durch ein Antriebsmittel (Motor) in eine drehende Bewegung versetzt werden kann, befestigt werden soll. Bei der bisher allgemein üblichen Art der Befestigung dieser Instrumente (Bohrer, Bürsten u. dgl.) wird das Instrument durch ein Klemmfutter festgehalten. Zum Anziehen des Klemmfutters ist eine mit Gewinde versehene Hülse aufzuschrauben.- Diese Befestigungsart hat verschiedene Nachteile. Wird das Klemmfutter nicht genügend angezogen, so kommt es vor, daß das Instrument vom Klemmfutter nicht mitgenommen wird und sich nicht mitdreht. Ferner leidet der Instrumentenhalter infolge Sterilisierung nach kurzer Zeit. Insbesondere wird das Gewinde teils durch die verwendeten Chemikalien, teils durch sich festsetzende Verunreinigungen (Schleifpulver, Pasten) unbrauchbar.Instrument holder for rotating medical instruments. The invention relates to an instrument holder for rotating medical instruments, which on a flexible shaft, which in turn is converted into a rotating movement can be offset, is to be fixed. With the so far generally The usual way of attaching these instruments (drills, brushes, etc.) will be Instrument held in place by a clamping chuck. To tighten the clamping chuck is to screw on a threaded sleeve.- This type of fastening has different Disadvantage. If the clamping chuck is not tightened enough, it can happen that the Instrument is not taken by the clamping chuck and does not turn with it. Further the instrument holder suffers after a short time as a result of sterilization. In particular the thread is partly due to the chemicals used and partly due to seizing Impurities (grinding powder, pastes) are unusable.

Der Erfindungsgegenstand zeigt diese Nachteile nicht. Nach der Erfindung besteht der Instrumentenhalter, wie aus der Zeichnung ersichtlich ist, aus einer kleinen, die Form einer viereckigen Pyramide aufweisenden Hülse, welche auf dem üblichen Bohnerschaft angebracht ist. Der Griff des Instruments hat die entsprechende Form, so daß er sich einfach in die zu seiner Aufnahme bestimmte Hülse hineindrücken läßt. Durch diese einfache Befestigungsart sitzt das Instrument fest. Ein Stehenbleiben des Instruments bei der Drehung des Mitnehmers ist durch die viereckige Form ausgeschlossen. Die Handhabung ist die denkbar einfachste. Die Sauberhaltung ist, da nur glatte Flächen vorhanden sind, wesentlich erleichtert. Schmutzrückhaltende und dein Verrosten leicht ausgesetzte Teile, wie das Gewinde der bisher üblichen Befestigungsart, sind nicht vorhanden.The subject of the invention does not show these disadvantages. According to the invention the instrument holder consists of one, as can be seen from the drawing small, the shape of a square pyramid having sleeve, which on the usual polish is appropriate. The handle of the instrument has the corresponding Shape so that it can simply be pressed into the sleeve intended for its reception leaves. This simple type of attachment means that the instrument is firmly in place. A stop of the instrument during rotation of the driver is excluded by the square shape. The handling is the simplest imaginable. The cleanliness is there just smooth Areas are available, much easier. Dirt-retaining and your rusting slightly exposed parts, such as the thread of the previously usual type of fastening, are unavailable.

Für Bürsten, wie sie in der Zahnpraxis Verwendung finden, bietet diese konische Form des Halters den weiteren Vorteil, daß sich die Borsten mehr fächerförmig ausbreiten können.For brushes such as those used in dental practices, this offers conical shape of the holder the further advantage that the bristles are more fan-shaped can spread.
