Abstract

Manual, intraocular lens comminutor: the application relates to a manually operated squeezing/tearing forceps for the intraocular comminution of the lens through a small opening. This device can supplement or replace a "lensmachine" excited with ultrasound in ophthalmological surgery. The principle is characterised in that a pair of metal or plastic forceps which opens in a forward movement grips the lentiform nucleus, squeezes it during the backward movement and severs it "in tearing fashion" with the last part of the backward movement. This can be done through an opening of only 3 mm on the eye. The lens residues can be aspirated through the guide pipe of the forceps or in a separate operation thereafter.

Description

Angaben zur GattungInformation on the genus

Der vorgegebene Phakozerkleinerer ermög­ licht dem Augenchirurg die Kataraktope­ ration durch einen nur 3 mm breiten Schnitt auszuführen.The specified phaco shredder enables illuminates the cataractope to the eye surgeon ration by only 3 mm wide Make cut.

Stand der TechnikState of the art

Es ist Stand der Technik die Phakozer­ trümmerung mittels eines mit Ultra­ schall angeregten hohlen Stößels vorzu­ nehmen.It is state of the art the phacozer debris using an ultra sound-excited hollow plunger to take.

Kritik des Standes der TechnikCritique of the state of the art

Die hierbei eingekoppelte Ultraschall­ energie belastet unnötigerweise die En­ dothelzellen als auch die gesamte Retina.The ultrasound coupled in here energy unnecessarily pollutes the environment dothelial cells as well as the whole Retina.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrun­ de, den Phako zu zerkleinern, ohne die empfindlichen Zellen im Auge zu belast­ ten.The invention is based on the object de to crush the phaco without the sensitive cells in the eye ten.

Lösungsolution

Die Aufgabe wird bei einer gattungs­ gemäßen Einrichtung durch die kennzeich­ nenden Merkmale des Patentanspruches ge­ löst.The task is in a genus appropriate facility by the character ning features of the claim ge solves.

Weitere Ausgestaltungen der ErfindungFurther refinements of the invention

Der Phakozerkleinerer besteht vorzugs­ weise aus einem rostfreien Metall, wel­ ches autoklaviert werden kann. Das Hand­ stück zur Bedienung ist so geformt, daß die Handhabung mit kleinen als auch gro­ ßen Händen gestattet. Gleichzeitig kön­ nen durch das Führungsrohr für die Zan­ genarme die zerkleinerten Phakoreste ab­ gesaugt werden.The phaco shredder is preferred wise from a rustproof metal, wel ches can be autoclaved. The hand Operating piece is shaped so that  handling small as well as large hands allowed. At the same time through the guide tube for the zan remove the shredded phaco residues be sucked.

Erzielbare VorteileAchievable advantages

Die äußerst empfindlichen Zellen des En­ dothels und der Retina werden geschont. Die Handhabung des Phakozerkleinerers, seine Vorbereitung für den Einsatz sowie seine Wartung und Kosten sind ungleich geringer als bei den existierenden "Pha­ komaschinen".The extremely sensitive cells of the En dothels and the retina are protected. The handling of the phaco shredder, its preparation for use as well its maintenance and costs are unequal less than the existing "Pha machines ".
