Description
Vorrichtung zum Schmelzschweißen für zahnärztliche und zahntechnische Zwecke Es ist bereits vorgeschlagen worden, elektrische Widerstandsschweißungen im Munde des Patienten mit kurzen Stromstößen vorzunehmen.Fusion welding device for dental and dental technology Purposes It has already been proposed electrical resistance welding to be carried out in the patient's mouth with short electrical surges.
Andererseits sind für örtliche Schweißungen oder Hartlotungen Vorrichtungen mit anklemmbarer Metallelektrode und freihändig führbarer, gegebenenfalls verstellbarer Widerstandselektrode, die mit niedriger Spannung arbeiten, bekannt.On the other hand, there are devices for local welds or brazing with clamp-on metal electrode and hand-held, adjustable if necessary Resistance electrodes that work with low voltage are known.
Die Erfindung bezweckt, Vorrichtungen der letztgenannten Art für zahntechnische Arbeiten durch besondere Gestaltung der Elektrodenhalter auszubilden.The invention aims to provide devices of the last-mentioned type for dental technology To train work through special design of the electrode holder.
Die Neuerung besteht bei einer solchen Vorrichtung gemäß der Erfindung darin, daß die in sich -federnde Klammer der Metallelektrode nach Art eines an einer Stelle unterbrochenen, etwa kreisförmigen Bogens gebogen ist, an dessen die Unterbrechungsstelle bildenden einander zugekehrten Enden die kontaktbildenden Klemmstücke angeordnet sind, und daß die Widerstandselektrode in einem Winkel zu ihrem gelenkig oder in fester Winkelstellung mit dem Handstück verbundenen Halter angeordnet ist.The innovation consists in such a device according to the invention in that the spring-loaded clamp of the metal electrode in the manner of one on one Point of interrupted, approximately circular arc is bent, at which the point of interruption forming ends facing each other arranged the contact-forming clamping pieces are, and that the resistance electrode is articulated or in an angle to it Fixed angular position is arranged with the handpiece connected holder.
In der Zeichnung ist I die Widerstandselektrode, 2 ihr Halter, zu dem sie sich in Winkelstellung befindet, 3 das den Halter 2 in veränderlicher Winkelstellung tragende Handstück, 5 die Klammer der Metallelektrode. Mit 4. sind die Verbindungskabel bezeichnet. 6, 7 ist ein Abwärtstransformator, an dessen Stelle aber auch jede andere geeignete Stromquelle, wie eine Batterie oder Dynamomaschine, treten kann, deren Spannung vorteilhafterweise so gering gehalten wird, daß jede physiologische Gefährdung des menschlichen Körpers ausgeschlossen ist.In the drawing, I is the resistance electrode, 2 is its holder which it is in an angular position, 3 that the holder 2 in a variable angular position carrying handpiece, 5 the clamp of the metal electrode. 4. are the connecting cables designated. 6, 7 is a step-down transformer, but also any other in its place suitable power source, such as a battery or dynamo machine Voltage is advantageously kept so low that any physiological hazard of the human body is excluded.
Besonders wichtig ist die Ausbildung des Halters 2, des Handstückes 3 und der Kabel ¢, derart, daß das Handstück leicht frei bewegt und die Widerstandselektrode an jeder Stelle eines Zahnersatzstückes, auch im Munde des Patienten, angesetzt werden kann, um örtlich und rasch Temperaturen bis zu etwa 2ooo° C zwecks Erzielung einer mechanischen Verbindung auf thermischem Wege hervorzurufen.The design of the holder 2, the handpiece, is particularly important 3 and the cable ¢, in such a way that the handpiece moves freely and the resistance electrode at every point of a piece of dental prosthesis, also in the mouth of the patient can be to locally and quickly temperatures up to about 2ooo ° C for the purpose of achieving to cause a mechanical connection by thermal means.
