Abstract
Burring equipment for hand or bent pieces for dental surgery. The device comprises an adaptor (2), for mounting on most of those pieces, provided with an extension arm (3) of which the free end has a burring head (13) of which the outer diameter is at the most 4,5 mm and the depth at the most 3 mm and which incorporates a burr holder (15) provided with a toothing (5) and with an axial threading (10) for screwing a miniature burr (12). The toothing (5) is driven by the toothed crown (7) of a shaft (4) which extends inside the extension arm (3); the other end thereof is coupled with the conventional hand pieces. The arrangement according to the invention is applicable to hand pieces for dental surgery.

PATENTANSPRÜCHE
1. Bohraufsatz für ein zahnärztliches Bohrhandstück mit einer Anpassungsbuchse zum Aufsetzen auf das Handstück, dadurch gekennzeichnet, dass diese Buchse mit einemVerlängerungsarm versehen ist, der an seinem freien Ende einen abgeflachten zylindrischen Bohrkopf aufweist, dessen äusserer Durchmesser höchstens 4,5 mm gross und der abgeflachte Teil höchstens 3 mm dick ist, und in welchem sich ein Fräserhalterzahnrad befindet, das in seiner Mitte ein Gewinde hat, welches zur Aufnahme eines Fräsers mit entsprechendem Gewinde versehen ist, wobei dieses Zahnrad von einer mit Ansatzzähnen versehenen Antriebswelle angetrieben wird, welche sich durch den Verlängerungsarm erstreckt, und deren anderes Ende zum Ankuppeln mit dem Handstück ausgebildet ist.
2. Bohraufsatz nach Patentanspruch 1, dadurch gekennzeichnet, dass das Zahnrad und die Antriebswelle aus einem härtbaren rostfreien Stahl besteht.
3. Bohraufsatz nach Patentanspruch 1, dadurch gekennzeichnet, dass der Fräser mit einem das Gewinde aufweisenden Befestigungsteil versehen ist, dessen Länge der axialen Länge des Gewindes des Fräserhalterzahnrades entspricht.
Die Erfindung betrifft einen Bohraufsatz gemäss Oberbegriff des Patentanspruchs 1.
Die bekannten Winkel- und Handstücke sind zu voluminös in der Stärke, bzw. Dicke und im Durchmesser. Damit kann man nicht zwischen den Zähnen, nach Verlust eines Zahnes, senkrecht zur Zahnachse bohren.
Der erfindungsgemässe Bohraufsatz erlaubt diese Nachteile zu beheben. Er ist im kennzeichnenden Teil des Patentanspruchs 1 definiert. Er erlaubt durch sein kleines Volumen proximal zu bohren, buccal bei Kindern und Erwachsenen, mit beschränkter Mundöffnung und retroradikular nach Wurzelspitzenresektion einzugreifen.
Ein Ausführungsbeispiel ist auf den Zeichnungen dargestellt.
Fig. 1 zeigt den Bohraufsatz auf dem Handstück 1.
Fig. 2 stellt den Längsschnitt des Bohraufsatzes dar, und Fig. 3 die Vergrösserung des Bohrkopfes 13.
Der Bohraufsatz weist eine Anpassungsbuchse 2 auf, die auf den meisten sich auf dem Markt befindlichen Hand- und Winkelstücken montierbar ist, die den Verlängerungsarm 3 trägt, an dessen Ende sich der abgeflachte zylindrische Bohrkopf 13 befindet.
Innerhalb des Verlängerungsarms 3 erstreckt sich die Antriebswelle 4, die von dem Halterring 14 anhand des Kugelrades 9 zentriert und getragen wird. Die Einstellung der Länge nach wird durch den Anschlagring 8 und Sicherungsring 6 geleistet.
An einem der Enden der Antriebswelle 4 sind die Antriebszähne 7 vorhanden, in denen die Zähne des Fräserhalterzahnrades 5 eingreifen. Die Drehung der Welle 4 wird dadurch perpendikulär auf den Fräserhalter 15 weitergeleitet.
Dieser ist durch den Deckel 11 innerhalb des Bohrkopfes 13 geführt.
Das Axialgewinde 10 innerhalb des Fräserhalters 15 ermöglicht die Befestigung des Miniaturfräsers 12.
Das zweite Ende der Antriebswelle 4 erstreckt sich ausserhalb der Anpassungsbuchse 2, und ist so entworfen, dass es sich mit den meisten Hand- und Winkelstücken ankuppeln lässt.

PATENT CLAIMS
1. Drilling attachment for a dental drilling handpiece with an adapter bushing to be placed on the handpiece, characterized in that this bushing is provided with an extension arm that has a flattened cylindrical drilling head at its free end, the outer diameter of which is at most 4.5 mm in size and the flattened one Part is at most 3 mm thick, and in which there is a cutter holder gear, which has a thread in its center, which is provided with a corresponding thread for receiving a cutter, this gear being driven by a drive shaft provided with shoulder teeth, which drives through the Extension arm extends, and the other end is designed for coupling to the handpiece.
2. Drill attachment according to claim 1, characterized in that the gear and the drive shaft consists of a hardenable stainless steel.
3. Drill attachment according to claim 1, characterized in that the milling cutter is provided with a fastening part having a thread, the length of which corresponds to the axial length of the thread of the milling cutter holder gear.
The invention relates to a drill bit according to the preamble of claim 1.
The known angle and hand pieces are too voluminous in strength, or thickness and in diameter. This means that you cannot drill between the teeth after losing a tooth, perpendicular to the tooth axis.
The drilling attachment according to the invention allows these disadvantages to be eliminated. It is defined in the characterizing part of patent claim 1. Due to its small volume, it allows drilling proximally, buccal in children and adults, with limited mouth opening and retroradicular intervention after root tip resection.
An embodiment is shown in the drawings.
1 shows the drilling attachment on the handpiece 1.
FIG. 2 shows the longitudinal section of the drill attachment, and FIG. 3 shows the enlargement of the drill head 13.
The drill attachment has an adapter sleeve 2, which can be mounted on most handpieces and contra-angles on the market, which carries the extension arm 3, at the end of which the flattened cylindrical drill head 13 is located.
Extending within the extension arm 3 is the drive shaft 4, which is centered and supported by the holder ring 14 by means of the ball gear 9. The length adjustment is made by the stop ring 8 and 6 circlip.
At one of the ends of the drive shaft 4, the drive teeth 7 are present, in which the teeth of the cutter holder gear wheel 5 engage. The rotation of the shaft 4 is thus passed perpendicularly to the milling cutter holder 15.
This is guided through the cover 11 inside the drill head 13.
The axial thread 10 within the cutter holder 15 enables the miniature cutter 12 to be attached.
The second end of the drive shaft 4 extends outside the adapter sleeve 2 and is designed in such a way that it can be coupled with most straight and contra-angle handpieces.
