Intraokularer PhakozerkleinererIntraocular phaco-disintegrator
Der vorgegebene Phakozerkleinerer ermöglicht dem Augenchirurg die Kataraktoperation durch einen nur 3 mm breiten Schnitt auszuführen.The predefined phacoemulsifier enables the eye surgeon to perform the cataract operation through an incision only 3 mm wide.
Es ist Stand der Technik die Phakozeertrünmerung mittels eines mit Ultraschall angeregten hohlen Stößels vorzunehmen.It is state of the art to perform phacoevolution using a hollow pestle stimulated by ultrasound.
Die hierbei eingekoppelte Ultraschallenergie belastet unnötigerweise die EncSothelzellen als auch die gesamte Retina.The ultrasound energy coupled in this way places unnecessary strain on the EncSothelial cells as well as the entire retina.
Der Erfinder liegt die Aufgabe zugrunde, den Phako zu zerkleinern, ohne die empfindlichen Zellen im Auge zu belasten.The inventor's task is to break down the phaco without putting strain on the sensitive cells in the eye.

Suction of the lens fragments can be done through the inner lumen or through conventional suction systems.

Intraokularer Phakozerkleinerer mit hochfrequenzstranunterstützter Greifwirkung und Infusionszufluß.Intraocular phacoemulsifier with radiofrequency assisted gripping action and infusion flow.
Variante des Intraokularen Phakozerkleinerers aus Schutzanspruch 1Variant of the intraocular phaco-crusher from claim 1
Durch !Einwirkung eines Hochfrequenzstrcmes über die isolierten Greifarme des Phakozerkleinerers wird exr-e EJ.s*;aißdenaturierung des Linsenkernes bewirkt. Hierdurch wird eine Konsistenzminderung der der gefaßten zu zerkleinernden Lins-onteile erreicht. Der Absaugvorgang der verbleibenden zerkleinerten Kernfragmente ist durch deren Konsistenzminderung erleichtert. Durch gleichzeitige Irifusionsspülung mit einer V>ccholimigen Flüssigkeit wird die Hingebung zusätzlich geschützt.The action of a high frequency current via the isolated gripping arms of the phaco shredder causes extreme denaturation of the lens nucleus. This reduces the consistency of the lens parts that are to be shredded. The suction process for the remaining shredded nucleus fragments is made easier by the reduction in their consistency. The lens is additionally protected by simultaneous infusion rinsing with a cholinic liquid.
Der Stromfluß läuft nur über beide Greifanrspitzen durch den erfaßten Lijisenteil.The current flow only runs through the gripped part of the line via both gripper tips.
Die mechanischen Bewwegungen der Greifarme werden auf ein Minimum reduziert. Die beeinflussten in ihrer Konsistenz geminderten Linsenkeme können leichter durch übliche Verfahren abgesaugt werden.The mechanical movements of the gripping arms are reduced to a minimum. The affected lens cores, which have reduced their consistency, can be more easily sucked out using conventional methods.
