Abstract
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 .
- 1) Einführen des Insertor-Kopfes (A) bis unter vorderen Kapselrand1) Insert the insertor head (A) to below the front edge of the capsule
- 2) Retraktion von (B), dadurch kontrollierte Teilentfaltung der Linse2) Retraction of (B), thereby controlled partial unfolding of the lens
- 3) Vorschieben der Linse in den Kapselsack durch (C) und z. T. (B)3) Advance the lens into the capsular bag through (C) and z. T. (B)
- 4) weitere Retraktion von (B) gegen (A) und (C) zur vollständigen Linsenentfaltung4) further retraction of (B) against (A) and (C) to complete Lens unfolding
- - Disposable (Einmalgebrauch, fertig sterilisiert)- Disposable (single use, fully sterilized)
- - Insertor in Einheit mit Linse- Insertor in unit with lens
- - Transparent (z. B. PMMA)- Transparent (e.g. PMMA)
- - Mehrteilig (z. B. 3), zueinander verschiebbare Teile)- Multi-part (e.g. 3), mutually displaceable parts)
- - Kurvengesteuerte Entfaltung der Linse- Curve-controlled unfolding of the lens
- - Insertionsvorgang zum Teil reversibel- The insertion process is partially reversible
- - ggf. Healon-Kanal- Healon channel if necessary
- - ggf. Ovale Querschnittsgeometrie (geringere Traumatisierung)- If necessary, oval cross-sectional geometry (less traumatization)
- - Keine Injektion, sondern Insertion, d. h. Gesamtvorgang kontrolliert- No injection, but insertion, i.e. H. Overall process checked
- - Implantation z. T. reveribel- Implantation z. T. reversible
- - Stets Sichtkontrolle durch Transparenz- Always visual control through transparency
- - Kein Ladevorgang, Zusatzinstrument, Umfassen, Linsenvorbereitung (H2O, Healon) notwendig- No loading, additional instrument, embracing, lens preparation (H2O, Healon) necessary
- - Schonung der Linse (geringe Bewegung!)- Protection of the lens (slight movement!)
- → insgesamt sicherer und schneller.→ overall safer and faster.
