Description

Die Erfindung betrifft ein Saug-Spülsystem, das für die Cata­ ractchirurgie Verwendung findet.The invention relates to a suction rinsing system for the Cata ractchirurgie is used.

Im Rahmen der Staroperation wird zunächst die vordere Linsen­ schale entfernt, dann der Linsenkern, daraufhin werden verblie­ bene Linsenreste schonend abgesaugt, ohne die hintere Linsen­ schale zu zerstören.As part of the star operation, the front lenses are first peel removed, then the lens core, then remain Level lens residues are gently sucked off, without the rear lenses destroy shell.

Bekannte Saug-Spülsysteme werden mit komplizierten, auch anfäl­ ligen Druckregelschaltungen ausgeführt in Verbindung mit Peri­ staltikpumpen, die bei Rückspülung unter Umständen zu hohe Drucke im Auge entstehen lassen.Known suction-rinsing systems are complicated, too current pressure control circuits implemented in connection with Peri static pumps that may be too high during backwashing Create prints in the eye.

Aus den Mängeln ergibt sich die Aufgabe, diese zu beseitigen. Der Erfindung liegt die Aufgabe zugrunde, ein einfaches, nicht störanfälliges Saug-Spülsystem für die Augenchirurgie zu ent­ wickeln, daß für den Saugvorgang einen kontinuierlich steigen­ den Unterdruck ermöglicht und das beim Ansaugen von nicht er­ wünchten Teilen, z. Bsp. Iris, hintere Kapsel, eine sofortige Rückspülung über die Ansaugöffnung mittels des durch die In­ fusionsflasche gewährleisteten hydrostatischen Druckes er­ möglicht.The task of eliminating these results from the defects. The invention is based, not a simple task interference-prone suction rinsing system for eye surgery wrap that a continuously rising for the suction process allows the vacuum and that when sucking in not he want parts, e.g. Eg Iris, rear capsule, an immediate one Backwashing via the suction opening by means of the In fusion bottle guaranteed hydrostatic pressure possible.

Durch Betätigung der Elektromagnete ist die Infusionslösung über das durch T-Stücke verkoppelte Schlauchsystem so schaltbar, daß sie primär über die Saugöffnung zufließt.When the electromagnets are actuated, the infusion solution is over the hose system coupled by T-pieces can be switched so that it flows primarily through the suction opening.

Letztere Schaltung hat den Vorteil des geringeren Gesamt­ flüssigkeitsaustausches in der Vorderkammer des Auges, denn Absaugung erfolgt dann nur, wenn der Sog durch elektrische Umschaltung freigegeben wird. Zudem besteht durch letztere Schaltung der wesentliche Vorteil, daß sich die Augenvorder­ kammer voll stellt, wenn bereits die dünne Spitze der Saug­ öffnung eingeschoben wird.The latter circuit has the advantage of lower overall fluid exchange in the anterior chamber of the eye, because Suction takes place only when the suction by electrical Switching is released. In addition, the latter exists Circuit the main advantage that the front of the eye chamber is full, if the thin tip of the suction opening is inserted.

Zum Ausführen des Verfahrens verwendbare Anlagen zeigen die schematischen Zeichnungen A und B.Plants that can be used to carry out the method are shown in the schematic drawings A and B.

Durch den Fußschalter (1) wird über die mechanisch veränder­ liche, im Nebenschluß zum Absaugschlauch (2) liegende Zuluft­ öffnung (3) der Sog an einem Saug-Spülhandgriff (4) so gere­ gelt, daß je nach Zuluftöffnung (3) an der Saugdüse (5) Null- bzw. Maximalsog herrscht.By the foot switch (1) in shunt with the suction hose (2) Supply located opening (3) of the suction to a suction-irrigation handle is mechanically Variegated Liche, eh so Gere (4), that depending on the air supply opening (3) at the suction nozzle ( 5 ) Zero or maximum suction prevails.

Zur sinnvollen Steuerung der Saug- (5) und Zuflußöffnung (10) bieten sich folgende Lösungen an:The following solutions are available for sensible control of the suction ( 5 ) and inflow openings ( 10 ):

Fig. A über einen elektrischen Fußschalter (12) umschaltbare Drehmagnete (6), Fig. A via an electrical foot switch (12) switchable rotary magnets (6),

Fig. B über einen elektrischen Fußschalter (12) umschaltbare Hubmagnete in drückender Ausführung (6). Fig. B via an electric foot switch ( 12 ) switchable solenoids in pushing version ( 6 ).

In Schaltstellung I kann die Infusion (9) in beiden Ausführungen an der Saugöffnung (5) über den Schlauch (13), durch T-Stück (14, 15) mit Infusionsschlauch (9) verbunden, zufließen, wodurch bereits bei Einführung der Öffnung (5) in das Auge eine stehende Vorderkammer gewährleistet ist. In Schaltstellung I ist also der Sog durch Ab­ klemmung von Schlauch (2) und Normalzufluß durch Abklemmung von Schlauch (11) unterbrochen.In switch position I the infusion ( 9 ) can flow in both versions at the suction opening ( 5 ) via the hose ( 13 ), connected by T-piece ( 14, 15 ) to the infusion hose ( 9 ), which means that the opening (( 5 ) a standing anterior chamber is guaranteed in the eye. In switch position I, the suction is thus interrupted by pinching off the hose ( 2 ) and normal inflow by pinching off the hose ( 11 ).

In Schaltstellung II wird Schlauch (2 u. 11) freigegeben, d. h., Sog wirkt an Öffnung (5), Normalzufluß läuft zu über Schlauch (10). Schlauch (13) ist abgeklemmt.In switch position II, hose ( 2 and 11 ) is released, ie, suction acts on opening ( 5 ), normal inflow runs through hose ( 10 ). Hose ( 13 ) is disconnected.

Bei Drehmagnetausführung erfolgt Abklemmung durch Exzenter (7, 8). Bei Hubmagnetausführung erfolgt Abklemmung durch Stempel (7). Ist während des Absaugvorganges Rückspülung erforderlich, erfolgt Umschaltung auf Stellung I, dadurch kommt sofort der hydrostati­ sche Druck der in variierbarer Höhe hängenden Infusionsflasche an der Düse (5) zur Wirkung. Nicht erwünschte angesaugte Teile wer­ den schonend zurückgespült.In the case of a rotary magnet version, it is disconnected by an eccentric ( 7, 8 ). In the case of the lifting magnet version, it is disconnected by means of a punch ( 7 ). If backwashing is required during the suction process, the system switches to position I, which means that the hydrostatic pressure of the infusion bottle hanging at a variable height at the nozzle ( 5 ) comes into effect. Unwanted suctioned parts are gently washed back.
