Description

Die Erfindung betrifft ein Werkzeug zum medizinischen Behandeln insbesondere von Zähnen, Knochensubstanzen etc. durch Laserstrahlen, mit einem Griffteil, an dessen vorderem Ende ein rohrförmiges, Lichtleiter aufweisendes Einsetzteil auswechselbar befestigt ist.The invention relates to a tool for medical Treating teeth, bone substances etc. in particular by laser beams, with a handle part, on the at the front end a tubular light guide Insert is interchangeably attached.

Es ist bekannt, bei einem Werkzeug zum Behandeln von Zähnen durch Laserstrahlen (mittels Spiegelumlenkung), die Lichtleitfasern bis zum vorderen Ende des Werkzeugs zu führen, wobei die Faserenden vorne vorstehen. Hierdurch sind die Faserenden einem Verschleiß ausgesetzt, so daß die Strahlen ungenau austreten. Hierbei ist es aus der deutschen Patentschrift 40 38 809 bekannt, am Werkzeug vorne ein Einsetzteil lösbar zu befestigen, so daß verschlissene Faserenden durch ein neues Einsetzteil ersetzt werden können.It is known in a tool for treating Teeth by laser beams (using mirror deflection), the optical fibers up to the front end of the tool with the fiber ends protruding at the front. Hereby the fiber ends are subject to wear, so that the rays come out imprecisely. Here it is from the German patent 40 38 809 known on the tool to attach an insert at the front so that worn fiber ends due to a new insert can be replaced.

Aufgabe der Erfindung ist es, ein Werkzeug der eingangs genannten Art so zu verbessern, daß bei geringem Verschleiß stets ein exakter Laserstrahl austritt.The object of the invention is a tool of the beginning to improve the type mentioned so that at low Wear always an exact laser beam emerges.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Einsetzteil am vorderen Ende mindestens eine Linse trägt.This object is achieved in that the insert at the front end at least one lens wearing.

Bei einem solchen Einsetzteil sind die Faserenden einem Verschleiß kaum noch ausgesetzt, da sie geschützt im Einsetzteil einliegen. Die am vorderen Ende angeordnete Linse kann verschieden geformt und/oder verschieden angeordnet sein, so daß Einsetzteile für die verschiedensten Arbeiten bestehen und nach Wahl eingesetzt werden können. Damit wird aufgrund der auswechselbaren unterschiedlichen Einsetzteile das Werkzeug zu einem Arbeitsinstrument hoher Flexibilität und Genauigkeit.With such an insert, the fiber ends are one Hardly exposed to wear as they are protected in the Insert insert. The one located at the front end Lens can be shaped differently and / or differently be arranged so that insert parts for the various works exist and of your choice can be used. This is due to the interchangeable different insert parts Tool for a work tool with high flexibility and accuracy.

Erforderlich ist es, daß im Einsetzteil zwischen Linse(n) und dem Ende des Lichtleiters ein Abstand angeordnet ist, in dem ein Distanzstück liegt, das eine mittlere Bohrung aufweist, durch die die Laserstrahlen vom Lichtleiter zur Linse verlaufen.It is necessary that in the insert between lens (s) and a distance is arranged at the end of the light guide, in which there is a spacer that has a central hole has through which the laser beams from the light guide to Lens run.

Ein fester Halt der Linse bei einfacher Konstruktion und Montage wird erreicht, wenn auf dem vorderen Ende des Rohres des Einsetzteils ein rohrförmiges Aufsetzstück außen koaxial aufgeschoben ist, das mit seinem vordersten Rand die Linse übergreift.A firm hold of the lens with simple construction and Assembly is achieved when on the front end of the Pipe of the insert part a tubular attachment piece is coaxially pushed on the outside, with its foremost Edge overlaps the lens.

Besonders vorteilhaft ist es, wenn eine Ausnehmung seitlich angeordnet ist, in der die Linse teilweise einliegt, wobei die Linse Strahlen zur Seite hin abgibt.It is particularly advantageous if a recess is arranged laterally, in which the lens partially lies, whereby the lens emits rays to the side.

Von größtem Vorteil ist, wenn am vorderen Ende des Einsetzteils ein Prisma oder Spiegel befestigt ist.The greatest advantage is if at the front end of the Insert a prism or mirror is attached.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen:Embodiments of the invention are in the Drawings are shown and are described in more detail below described. Show it:

Fig. 1: Einen Schnitt durch das Werkzeug mit befestigtem Einsetzteil in vergrößertem Maßstab. Fig. 1: A section through the tool with attached insert part on an enlarged scale.

Fig. 2: Einen Längsschnitt durch das Einsetzteil in vergrößertem Maßstab und Fig. 2: A longitudinal section through the insert on an enlarged scale and

Fig. 3: einen Längsschnitt durch das vordere Ende des Einsetzteils in vergrößertem Maßstab. Fig. 3 shows a longitudinal section through the front end of the insert in an enlarged scale.

Das Werkzeug 1 weist ein Griffteil 2 auf, das einen Längshohlraum 3 besitzt und an seinem vorderen Ende um einen Winkel α von ca. 50 Grad abgebogen ist. Im Längshohlraum 3 liegt ein Lichtleiterkabel 5 koaxial ein, das an ein Eingangslichtleiterkabel 6 über Linsen 7, 8 angeschlossen ist.The tool 1 has a handle part 2 , which has a longitudinal cavity 3 and is bent at its front end by an angle α of approximately 50 degrees. An optical fiber cable 5 is coaxially inserted in the longitudinal cavity 3 and is connected to an input optical fiber cable 6 via lenses 7 , 8 .

Am vorderen Ende 4 ist ein Einsetzteil 9 lösbar und damit auswechselbar befestigt, das ein dünnes Hauptrohr 10 von ca. 2,5 mm Außendurchmesser aufweist. Im Längshohlraum des Hauptrohres 10 liegt ein Lichtleiterkabel 11 ein, das einen Lichtleitermantel 12 besitzt, das die Lichtleitfasern umgibt.At the front end 4 , an insert 9 is detachably and thus interchangeably fastened, which has a thin main tube 10 of approximately 2.5 mm outer diameter. In the longitudinal cavity of the main tube 10 there is an optical fiber cable 11 , which has an optical fiber jacket 12 which surrounds the optical fibers.

Das vordere Ende des Hauptrohres 10 besitzt am Außenumfang einen geringen Durchmesser und damit eine stufenförmige Abdrehung 13, auf der ein rohrförmiges Aufsatzstück 14 im klemmenden Halt aufgesteckt ist, dessen Außendurchmesser dem Außendurchmesser des Hauptrohres 10 entspricht. Das Aufsatzstück 14 ist an seinem vorderen Ende außen konisch zulaufend geformt und der koaxiale Innenhohlraum des Aufsatzstückes 14 bildet am vorderen Ende eine ringförmige Verengung 15, mit dem eine Linse 16 (Sammellinse) übergriffen wird. The front end of the main tube 10 has a small diameter on the outer circumference and thus a step-shaped twist 13 , on which a tubular attachment piece 14 is placed in the clamping stop, the outer diameter of which corresponds to the outer diameter of the main tube 10 . The attachment piece 14 is conically tapered at its front end and the coaxial inner cavity of the attachment piece 14 forms an annular constriction 15 at the front end, with which a lens 16 (converging lens) is overlapped.

Zwischen der Linse 16 und dem Ende des Lichtleiterkabels 11 besteht ein Zwischenraum A von ca. 1 mm Länge. Dieser Zwischenraum ist durch ein Distanzstück 17 ausgefüllt, das außen sich stufenförmig zu den Linsen 16 hin verjüngt und eine koaxiale Längsbohrung 18 besitzt, durch die die Laserstrahlen vom Lichtleiterkabel 11 zur Linse 16 gelangen.Between the lens 16 and the end of the optical fiber cable 11 there is a space A of approximately 1 mm in length. This intermediate space is filled by a spacer 17 , which tapers towards the lenses 16 on the outside in a step-like manner and has a coaxial longitudinal bore 18 through which the laser beams reach the lens 16 from the optical fiber cable 11 .

Wie Fig. 1 zeigt, sind im Innern des Griffteils 2 nahe des vorderen Endes 4 zwischen dem inneren Ende des Einsetzteils 9 und dem vorderen Ende des Lichtleiterkabels 5 zwei Linsen 19, 20 angeordnet, die eine Verbindung zwischen dem Lichtleiterkabel 5 und dem Einsetzteil 9 bilden.As shown in FIG. 1, two lenses 19 , 20 are arranged in the interior of the handle part 2 near the front end 4 between the inner end of the insert part 9 and the front end of the optical fiber cable 5 , which form a connection between the optical fiber cable 5 and the insert part 9 .

Statt einer Linse 16 können auch zwei oder mehrere Linsen und/oder ein Spiegel oder Prisma am vorderen Ende des Einsetzteils 9 befestigt sein. Je nach Verwendungszweck sind Art, Größe und Anzahl der Linsen ausgebildet. Ferner kann am Einsetzteil 9 die Austrittsöffnung für die Laserstrahlen auch seitlich am vorderen Ende insbesondere des Hauptrohres 10 angeordnet sein, so daß die Strahlen schräg zur Längsachse eines Einsetzteils 9 und/oder rechtwinklig zur Längsachse austreten. Hierbei werden die Strahlen durch ein Prisma oder Spiegel zur seitlichen Linse hin umgelenkt.Instead of a lens 16 , two or more lenses and / or a mirror or prism can also be attached to the front end of the insert part 9 . Depending on the intended use, the type, size and number of lenses are designed. Furthermore, the outlet opening for the laser beams can also be arranged laterally on the insert part 9 at the front end, in particular of the main tube 10 , so that the beams exit obliquely to the longitudinal axis of an insert part 9 and / or at right angles to the longitudinal axis. The rays are deflected towards the side lens by a prism or mirror.

Zur Kühlung und zum Freilegen der Arbeitsstelle am Werkstück (Zahn) wird durch den Längshohlraum 3 des Werkzeugs 1 Luft 21 und Wasser 22 geführt.Air 21 and water 22 are passed through the longitudinal cavity 3 of the tool 1 for cooling and for exposing the work site on the workpiece (tooth).
