Dauermagnete zur Wiederherstellung der AUgenlidfunktion Permanent magnets for Wi Eder manuf RECOVERY the eyelid function
bei i'azialparesewith i'azialparese
Die Erfindung "betrifft Baue magnete zum implantieren in die Augenlidränder, um hierdurch den bei Fazialparese gestörten Lidverschlujä wieder herzustellen.The invention "relates to build magnets for implantation in the Eyelid rims to avoid the disturbed facial palsy Restore Lidverschlujä.
Bei I'azialparese kann in vielen FälJ en ein natürlicher Verschluß der Augenlider nicht mehr herbeigeführt werden, sodau durch .iustrocknen und irübvjerden d er Hornhaut die Sehfähigkeit verloren geht. Bisherige Maßnahmen zur Abhilfe bestehen z.B. darin, die Augenlider bis auf einen engen Spalt zusammenzunähen oder das Oberlid mit Gewichten zu beschweren. Es wird auch vorgeschlagen, die Lider mit schwachen metallischen oder aus Kunststoffen bestehenden Federn zu schließen. Auch der Gedanke, hierzu Magnete zu verwenden, die außen auf die Augenlider in Form kleiner q.uaderförniger Stücke, z. B. aus dem sehr energiereichen Werkstoff SraCo,- aufgebracht werden, wobei als Gegenstück ein Weicheis enteil dient, ist bekannt.In many cases of facial palsy, a natural closure can occur the eyelids can no longer be brought about, sodau the cornea dries out and obscures vision get lost. Previous remedial measures exist E.g. in sewing the eyelids together except for a narrow gap or to weigh down the upper eyelid with weights. It is also suggested to use faint metallic or metallic lids to close springs made of plastics. Also the thought of using magnets on the outside of the eyelids in the form of small, square-shaped pieces, e.g. B. off the very high-energy material SraCo, - are applied, with a soft ice enteil serving as a counterpart is known.
Bei allen oben vorgeschlagenen mechanischen Lethoden ist ein hinreichend sicherer Lidverschluß nicht gewährleistet. Das erwähnte äußerliche Aufbringen mehrerer kleiner Einzelmagnete ergibt deutlich entstellende 'Veränderungen der Lider und führt zu ungleichen Schließkräften, da ein sicheres fixieren nicht möglich ist.For all of the mechanical methods suggested above, one is sufficient secure lid closure is not guaranteed. The mentioned external application of several small individual magnets results clearly disfiguring 'changes in the eyelids and leads to unequal closing forces, since a secure fixation is not possible is possible.

Srfindungsgemäß wird deshalb vorgeschlagen, hierfür druht- oder bandförmige Dauermagnete, die den Augenro.dius angepasst sind, direkt in die .Augenlider zu implantieren. Als praktisch erv/eisen sich z. B. diametrax nagnetisierte PtCo-j.'agnetdrähte oder Kunststoffbänder mit eingelegten SmCο^- Stücken. Ebenso können flexible Magnetbänder benutzt werden, die als Füllstoff feines Pulver eines energiereichen Dau-rmagnetWerkstoffes (z.3. SmCOp- Pulver) besitzen.According to the invention, it is therefore proposed that this or ribbon-shaped permanent magnets that fit the eye radius are to be implanted directly into the eyelids. As practical arise z. B. diametrax magnetized PtCo-j. Magnet wires or plastic straps with inlaid pieces of SmCο ^. as well Flexible magnetic tapes can be used, which are filled with a fine powder of an energy-rich permanent magnet material (e.g. 3. SmCOp powder).
Die benötigten Schließkräfte von 200 bis 300 l.iillipond bei geöffneten Augenlidern und 1600 bis 2000 Aillipond zum sicheren Zuhalten der Lider las en sich &.B. mit den oben erwähnten PtCo-IIagnet draht en von 1 mm bis 1,5 mm ^ und einer Bogenlänge zwischen 14 und 22 nm sicher erzielen. Anstelle eines runden Drahtquerschnitxes kann auch ein entsprechender ovaler oder rechteckiger Draht benutzt werden. Von besonderem Vorteil ist dabei die Verwendung eines kleineren und leichteren I.iagneten im Unterlid,damit dieses nicht bei geöffnetem Auge durch die Schwerkraft heruntergezogen rvird, während beim Oberlid das Gewicht eines größeren magneten von Vorteil ist.The required closing forces of 200 to 300 l.iillipond with open eyelids and 1600 to 2000 Aillipond for securely holding the eyelids can be read & .B. With the above-mentioned PtCo-IIagnet wires from 1 mm to 1.5 mm ^ and an arc length between 14 and 22 nm reliably achieve. Instead of a round wire cross-section, a corresponding oval or rectangular wire can also be used. Of particular advantage is the use of a smaller and lighter I.iagneten in the lower eyelid, so that this vird r, whereas in the upper eyelid, the weight is pulled down by gravity is not opened eye of a larger magnet is advantageous.
Pig. 1 zeigt ein geöffnetes Auge mit den implantierten I.iagneten 1 und 2. Daneben in I1Ig. 2 ist das durch die diametral magnetisieren magnete geschlossene Auge dargestellt. In i'ig. 3 ist ein Schnitt durch den vorderen Teil des Auges und durch die Augenlider mit den implantierten Magneten 1 und 2 gezeigt. Die i.iagnetisieruiigsrichtung ist in Pig. 4 an dem vergrößert dargestelltn Querschnitt der Lagnete 1 und 2 zu erkennen. Sie gilt sinngemäß auch für Llagnefbänder mit eingebetteten iiiinze!magneten oder Kunststoffstreifen mit magnetpulver als Füllstoff.Pig. 1 shows an open eye with the implanted I. agnets 1 and 2. Next to it in I 1 Ig. 2 shows the eye closed by the diametrically magnetized magnets. In i'ig. 3 shows a section through the front part of the eye and through the eyelids with the magnets 1 and 2 implanted. The direction of diagnosis is in Pig. 4 can be seen from the enlarged cross-section of the layers 1 and 2. It also applies accordingly to lay-on tapes with embedded magnets or plastic strips with magnetic powder as a filler.
