Abstract

The folded lens is accommodated in a container in several sections at the end of a stem. The sections (2,3) of the container (1) are movable in relation to each other, so as to unfold the lens once inserted, and typically in the lengthwise direction of the instrument, and working in guide grooves. They can be mounted on oblong slides (A,B) actuated by handles (7,8). There can also be a tappet, whose forward end (9) slides into the container.

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to Preamble of claim 1.

Die Aufgabe besteht darin, daß der Querschnitt des Linsenbehälters beim Öffnen zum Entfalten der Linse sich nicht vergrößert.The task is that the cross section of the Lens case when opening to unfold the lens does not grow.

Diese Aufgabe wird erfindungsgemäß durch die kenn­ zeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the kenn Drawing features of claim 1 solved.

Die Unteransprüche enthalten vorteilhafte Weiterbil­ dungen der Erfindung.The subclaims contain advantageous further developments end of the invention.

Anhand der Figuren wird die Erfindung noch näher er­ läutert. Es zeigt:Based on the figures, the invention is he even closer purifies. It shows:

Fig. 1 eine perspektivische Darstellung der Vor­ richtung; Fig. 1 is a perspective view of the device before;

Fig. 2 einen Querschnitt durch das Einsetzwerkzeug im Bereich der Schieber; und2 shows a cross section through the insertion tool in the area of the slide. and

Fig. 3 das Einsetzwerkzeug mit in den Kapselsack eines Auges eingesetztem Linsenbehälter. Fig. 3 shows the insertion tool with a lens container inserted into the capsular bag of an eye.

Am vorderen Ende eines Einsetzwerkzeugs 4, das läng­ lich ausgebildet ist, befindet sich ein Linsenbehäl­ ter 1, in welchem eine gefaltete Linse angeordnet ist. Die beiden Linsenbehälterteile 2 und 3 können einstückig mit Schiebern A und B ausgebildet sein und durch die vorderen Enden der beiden Schieber A und B gebildet sein. Das Material der Teile des Einsetz­ werkzeuges 4 besteht bevorzugt aus durchsichtigem Material, z. B. PPMA. Zur Betätigung der Schieber und damit zum Gegeneinanderverschieben der Linsenbehäl­ terteile 2 und 3 sind an den Schiebern A und B Hand­ griffe 7 und 8 vorgesehen. Ein Stößel C kann mit sei­ nem vorderen an den Querschnitt der Schieber A und B bzw. dem Linsenbehälter 1 angepaßten vorderen Ende 9 in das Linsenbehälterinnere eingeschoben werden, um die Intraokularlinse beim Implantieren aus dem Behäl­ ter vollständig entfernen zu können. Beim Implantieren (Fig. 3) werden die beiden Schieber A und B gegen­ einander verschoben. Bevorzugt wird der untere Schie­ ber B zurückgezogen. Je nachdem wie stark der Schie­ ber B zurückgezogen wird, öffnet sich der Linsenbe­ hälter 1, und in diesem Ausmaß entfaltet sich die Linse in den Kapselsack des Auges. Zur exakten Füh­ rung, insbesondere zur exakten Längsführung der Schieber A und B zueinander sind Führungsnuten 5, 6 in den Schiebern und/oder in den Behälterteilen 2, 3 vorgesehen. At the front end of an insertion tool 4 , which is formed Lich, there is a lens container 1 , in which a folded lens is arranged. The two lens container parts 2 and 3 can be formed in one piece with sliders A and B and formed by the front ends of the two sliders A and B. The material of the parts of the insertion tool 4 is preferably made of transparent material, for. B. PPMA. Tert rush for actuating the slide and thus to the mutual displacement of the Linsenbehäl 2 and 3 are on the sliders A and B handles 7 and 8 are provided. A plunger C can be inserted with its front end 9 adapted to the cross-section of the sliders A and B or the lens container 1 into the interior of the lens container in order to be able to remove the intraocular lens from the container during implantation. When implanting ( Fig. 3), the two slides A and B are moved against each other. The lower slide is preferably withdrawn via B. Depending on how much the slide is pulled back over B, the Linsenbe container 1 opens, and to this extent the lens unfolds in the capsular bag of the eye. For exact guidance, in particular for the exact longitudinal guidance of the slides A and B to one another, guide grooves 5 , 6 are provided in the slides and / or in the container parts 2 , 3 .
