Abstract
Gerät zur Entfernung der vorderen Kapsel der Augenlinse bei Kataraktoperationen Dadurch gekennzeichnet, dass durch die Leitröhre, welche in die Vorderkammer des menschlichen Auges eingeführt wird, ein Cuttering transportiert wird.Device for removing the anterior capsule of the eye lens during cataract operations. Characterized in that a cutter is transported through the guide tube, which is inserted into the anterior chamber of the human eye.
Description
Bei der hier vorgestellten Erfindung handelt es sich um ein medizintechnisches Gerät zur Entfernung der vorderen Kapsel der Augenlinse so wie es bei einer Kapsulorhexis im Falle einer Katarakt-Operation geschieht.In the invention presented here is a medical device for removing the anterior capsule of the eye lens as it happens in a capsulorhexis in the case of cataract surgery.
Die heutzutage gängige Methode bedient sich eines von zwei Instrumenten. Einige Ärzte bevorzugen eine Pinzette, andere wiederum eine gebogene Nadel. Die sich hierbei ergebene Problematik gründet darauf, dass die Entfernung der vorderen Kapsel ein manueller Vorgang ist, das bedeutet, dass die Kapsulorhexis manchmal zu groß oder nicht rund genug wird oder gar einreißt. Einem Einriss folgt ein großes operatives Hindernis mit komplizierten und suboptimalen Alternativen.The current method uses one of two instruments. Some doctors prefer tweezers, others use a curved needle. The problem arising from this is that the removal of the anterior capsule is a manual procedure, which means that the capsulorhexis sometimes becomes too large or not round enough or even tears. A tearing follows a major operational obstacle with complicated and suboptimal alternatives.
Die Erfindung ermöglicht das Einführen eines Cutter-Ringes durch eine Leitröhre über eine Inzision in die Vorderkammer des Auges. Dort angekommen, wird über einen Schubmechanismus (siehe Zeichnung und Schutzantrag) ein formstabiler Schneidering (Cutter-Ring) aus der Leitröhre hinausgeschoben, welcher sich im Vorhof entfaltet. Danach drückt der Operateur den Cutter-Ring gegen die Linse, wobei die vordere Kapsel ausgestanzt wird. Diese ausgestanzte Kapsel ist immer perfekt rund und weist immer denselben Radius auf.The invention allows insertion of a cutter ring through a guide tube via an incision into the anterior chamber of the eye. Once there, over a push mechanism (see drawing and protection request) a dimensionally stable cutting ring (cutter ring) is pushed out of the guide tube, which unfolds in the forecourt. Thereafter, the operator presses the cutter ring against the lens, wherein the front capsule is punched out. This punched capsule is always perfectly round and always has the same radius.
Danach ergeben sich zwei Möglichkeiten für den Operateur. Entweder zieht er die Kapsel mit dem Cutter-Ring zurück in die Leitröhre und entfernt die letztere aus dem Auge. Oder das Gerät wird entfernt und die Kapsel wird nachträglich durch eine Pinzette gefasst und herausgezogen oder durch das ultrasonic Messer bei der Linsenzerteilung aufgesogen.Then there are two options for the surgeon. Either he pulls the capsule with the cutter ring back into the guide tube and removes the latter from the eye. Or the device is removed and the capsule is subsequently grasped by a pair of tweezers and pulled out or sucked up by the ultrasonic knife when dividing the lens.
Die Erfindung ermöglicht eine schnelle, sicher und vor allem konstante Kapsulorhexis, welche auch für angehende Augenchirurgen eine leichtere Alternative zur herkömmlichen Methode sein kann.The invention enables a fast, safe and above all constant Kapsulorhexis, which can be a lighter alternative to the conventional method for aspiring eye surgeons.
