Description
94289428
Die Erfindung bezieht sich auf einen Handapplikator für die Laserchirurgie,bei dem eine Laserfaser koaxial flüssigkeits-oder gasgekühlt in einem rohrförmigen Griffgehäuse gelagert ist.The invention relates to a hand applicator for laser surgery, in which a laser fiber is coaxial or fluid Is stored gas-cooled in a tubular handle housing.
Solche Applikatoren sind an sich in verschiedenen Ausführungsformen bekannt. Die bisher verwendeten Geräte weisen eine Fokussieroptik zur Erzielung eines frei wählbaren Bestrahlungsabstandes auf und erfordern daher doch beachtliche Dimensionen.Der durchschnittliche Mindestdurchmesser beträgt 12 mm und die Mindestlänge liegt bei etwa 12 cm.Die Führungsröhrchen der Laserfaser weisen Durchmesser von 3 bis 4 mm auf und sind je nach Situation der Applikation in verschiedenen Formgebungen ausgebildet.Dies erfordert,daß bei jedem Eingriff mehrmals das Führungsröhrchen ausgewechselt werden muß.Abgesehen von der unerwünschten Unterbrechung der Applikationskontinuität bedeutet diese Auswechslung eine Verlängerung der Operationszeit und einen speziellen Aufwand an verschieden gebogenen Röhrchen, die bereitgestellt werden müssen und am Gerätetisch Lagerplatz erfordern.Such applicators are per se in various embodiments known. The devices used so far have a focusing optics to achieve a freely selectable Irradiation distance and therefore require considerable dimensions. The average minimum diameter is 12 mm and the minimum length is about 12 cm. The guide tubes of the laser fiber have a diameter from 3 to 4 mm and are designed in different shapes depending on the application situation. This requires that The guide tube has to be replaced several times with each intervention, apart from the undesired one Interruption of the application continuity, this replacement means an extension of the operating time and a special effort in differently curved tubes that have to be provided and storage space on the equipment table require.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde einen Handapplikator der eingangs genannten Art zu schaffen, mit dem ein zeitraubendes und umständliches Austauschen während der Operation entfällt und die Bereitstellung mehrerer Ausführungsformen überflüssig macht.The present invention is based on the object of creating a hand applicator of the type mentioned at the outset, This eliminates the need for time-consuming and cumbersome replacement during the operation and the provision of several Eliminates the need for embodiments.
Diese Aufgabe wird durch die im Anspruchl angegebenen Maßnahmen in überraschend einfacher und zuverlässiger Weise gelöst.In der nachfolgenden Beschreibung wird ein Ausführungsbeispiel beschrieben und anhand einer Ansichtsskizze in der Zeichnung verdeutlicht.In den Unteransprüchen sindThis object is achieved in a surprisingly simple and reliable manner by the measures specified in Claim 1 An exemplary embodiment is provided in the following description described and illustrated by means of a sketch in the drawing. The subclaims are

Das in der Figur der Zeichnung gezeigte Ausführungsbeispiel setzt sich aus zwei sogenannten Baugruppen zusammen,nämlich aus dem Griffgehäuse 11 mit der Flüssigkeitsoder Gaszuführung 12 sowie den Koppelelementen 13a,13b für das flexible Transmissonskabel 14 in dem die Laserlicht-Leitfaser 10 geführt und gelagert ist,und aus dem langgestreckten ,rohrförmigen Gehäuse 17,18 ,das mit einer Anschlußkupplung für das Griffstück 11 versehen ist.Das rohrförmige Gehäuse 17,18 setzt sich selbst aus einem biegsamen Röhrchen 18 mit einem abgerundeten Kantenschutzaufsatz 18a und einem vierkantigen Anschlußstück 17 zusammen. Letzteres weist an seinen beiden Seitenflächen Abflachungen 17a auf,die eine gute Aufsteckführung erlauben,sowie ein Verschlußelement 16,das mit dem Kuppelelement 15 des Griffgehäuses 11 korrespondiert.Beide Uerschluß-bzw.Kuppelelemente 15,16 können in Form eines Bajonettverschlusses oder eine-s Feder-Rastenverschlusses bzw. Steck-Klemmverschlusses ausgebildet sein.Da diese seit langem zum Stand der Technik zählen,erscheint eine Beschreibung überflüssig .The embodiment shown in the figure of the drawing consists of two so-called assemblies, namely the handle housing 11 with the liquid or gas supply 12 and the coupling elements 13a, 13b for the flexible transmission cable 14 in which the laser light guide fiber 10 is guided and stored, and from the elongated , tubular housing 17,18 with a Connection coupling for the handle 11 is provided. The tubular housing 17,18 is composed of a flexible one Tubes 18 with a rounded edge protection attachment 18a and a square connector 17 together. The latter has flats 17a on both of its side surfaces, which allow good plug-on guidance, as well as a Closure element 16, which with the coupling element 15 of the handle housing 11 corresponds. Both closure or coupling elements 15, 16 can be in the form of a bayonet lock or a spring latch lock or plug-in clamp lock Since these have long been part of the state of the art, a description appears superfluous .
Das biegsame Röhrchen- 18 kann aus einer weichen Messing-Legierung hergestellt sein,es sind aber auch andere Legierungen denkbar.Wesentlich ist,daß das Röhrchen von Hand leicht verbogen werden kann,ohne daß Bruchstellen auftreten und jederzeit auch wieder rückgestellt werden kann. .Es sind natürlich auch andere Metall-Legierungen aus Blei oder Zinn denkbar,Voraussetzung ist die oben gestellte Bedingung der leichten,beschädigungslosen Verbiegbarkeit.The flexible tube 18 can be made of a soft brass alloy be manufactured, but there are also other alloys conceivable. It is essential that the tube by hand can be bent easily without breaking points and can be reset at any time. Of course there are also other metal alloys made of lead or Tin conceivable, prerequisite is the condition set out above the easy, damage-free bendability.
