Description
Ultraschall-ZahnbehandlungsgerätUltrasonic dental treatment device
Die Erfindung betrifft ein Ultraeehall-Zahnbehandlunge«- gerät mit einem Handstück, welches In einer Vorderöffnung auswechselbare Einsatz spitzen aufnimmt und in seinem Inneren einen Übertrager enthält, der die am Hinterende des Hsndstückes über ein Kabel augeführte elektrische Energie in mechanische Schwingungen umwandelt und den Hinterenden der Eilnaatzspitzen zuführt„The invention relates to an Ultraeehall dental treatment «- device with a handpiece, which takes exchangeable insert points in a front opening and in its interior contains a transformer that carries the electrical energy out via a cable at the rear end of the handpiece converted into mechanical vibrations and fed to the rear ends of the fastener "
Bsi den vorbekannten Zahnbehandlungsgeräten wird dem Handstück während des Betriebes Wasser zugeführt, das über eine 3Mise r,usgesprüht wird. Der kontinuierliche Durchfluß von Wasser ist auch erforderlich, um das Handstück zu kühlen«Bsi the previously known dental treatment devices, water is supplied to the handpiece during operation, which over a 3Mise r that is sprayed out. The continuous flow of water is also required to cool the handpiece «
Da der Wasserdurchfluß ständig aufrecht erhalten werden muß und auch das Handstück eine relativ schlanke Gestalt bt-nStlgt, hat man zur elektrischen Steuerung des Übertragers bisher einen PEdalschalter verwendet, der jedoch für den Zahne-rat nachteilig ist. Die Nachteile liegen darin, daß sich der Zahnarat gegenüber dem Patienten nicht so bewegen kann, wie er es bei der Verwendung anderer Zahnbehandlungs-Because the water flow is constantly maintained must and also the handpiece has a relatively slim shape bt-nStlgt, you have to electrically control the transformer So far a PEdal switch has been used, but for the Zahne-Rat is disadvantageous. The disadvantages are that the teeth do not move that much in relation to the patient as he would when using other dental treatment

geräte kann, bei denen das Betätigungsorgan für den Schalter unmittelbar am Handstück vorgesehen ist. Solohe Sohaltvorriohttingen am Handstück haben meistens die Gestalt eines Hebels, der in bequemer Lage in der Hähe des Bohrers am Handetüok vorgeeehen ist. Die Schalterbetätigung bereitet keine Schwierigkeiten, da der Bohrer im allgemeinen stets in gleicher Richtung bewegt wird» Eine solche Hebelsohaltvorrlohtung ist jedooh bei Ultraschall-Geräten unbequem, da diese während der Behandlung in vielen verschiedenen Richtungen bewegt werden.devices in which the actuator for the switch is provided directly on the handpiece. Solohe sohaltvorriohttingen on the handpiece usually have the shape of a lever which is conveniently positioned at the level of the drill on the handpiece. Actuating the switch does not cause any difficulties, since the drill is generally always moved in the same direction. However, such a lever locking device is inconvenient with ultrasound devices, since they are moved in many different directions during treatment.
Ziel der Erfindung ist es, das vorgenannte Problem so zu !Seen, daß die Schaltvorrichtung innerhalb des Hand-Stücks nur sehr wenig Raum benötigt und daß die Schaltvorrichtung sich während der Behandlung in jeder beliebigen Stellung allein dadurch ein« und ausschalten läßt, daß man den Daumen benutzt, während die übrigen Finger in fester Lage das Handstück führen können.The aim of the invention is to solve the aforementioned problem in such a way that the switching device requires very little space within the handpiece and that the switching device can be switched on and off in any position during treatment. that one uses the thumb, while the other fingers can guide the handpiece in a fixed position.
Zur Lösung der vorgenannten Aufgabe ist erfindungsgemäß die Anordnung so getroffen, daß am Hinterende des Handstückes für den übertrager ein elektrischer Schalter vorgesehen 1st, der über einen im Inneren des Handetücke längsverschleblioh gelagerten Sohleber und einen in einer Ringnut der Handstückmantelhülse begrenzt axial verschiebbar en, mit dem Schiebervorderende verbundenen Betätigung·* ring betätigbar ist.According to the invention, the above object is achieved the arrangement is made so that an electrical switch is provided at the rear end of the handpiece for the transmitter, which is via a switch inside the handpiece Longitudinally stored sole boar and one in one Ring groove of the handpiece casing sleeve, axially movable to a limited extent, actuation connected to the front end of the slide * ring is operable.
