Definitions

  • Apparatus and injector for folding an intraocular lens Cartridge and injector
  • the invention relates to a device for folding an intraocular lens, comprising two hinged, practically mirror-symmetrical half-shells which can be moved relative to each other from an open position to a closed position to fold the intraocular lens, wherein in the closed position the half-shells form a cavity for receiving the intraocular lens in an injection-ready position.
  • an artificial lens a so-called intraocular lens
  • an ocular incision of typically 2 to 4 mm is made, through which the natural eye lens is removed and replaced by the implant.
  • the artificial lens is inserted in the folded state through the incision in the capsular bag. Once the folded lens is inserted into the capsular bag, it unfolds back to its original shape.
  • cartridges To insert an intraocular lens, cartridges have been developed in recent years in which a lens can be loaded and then ejected from the cartridge by means of an injector. Examples of such cartridges and injectors are known from US Pat. Nos. 4,681,102, 5,582,614, 5,947,975 and US 2004/0199174.
  • the cartridge which is designed as a fair device for the lens, and the injector nozzle are separate parts.
  • the Cartridge can be inserted into the injector housing, whereupon the injector nozzle can be screwed on the front of the injector housing.
  • the cartridge is in one piece of a folding device and an injector nozzle.
  • FIG. 2 shows in FIG. 2 an injector device in which the injector housing consists in one piece of a cylinder for accommodating the piston, a folding device for the lens and an injector nozzle.
  • EP 1 290 990 and WO 03/045285 show, in later years the original cartridge construction, which has two shells connected by a single hinge, with or without grooves for detecting the edges of the lenses, was still retained.
  • US 5499 987 which provides a special design of the grooves. Namely, it is proposed to make the grooves less deep against the nozzle so as to facilitate their transport into the nozzle (Figs. 34, 39, 40 and 41). Because cartridges with grooves for detecting the lens edges did not satisfy folding, US 204/0199174 proposes a cartridge which also has two half-shells in a conventional manner. In addition, however, a band is provided which leads from one half-shell to the other half-shell. As a result, a space is formed between a belt loop and the half shells. The lens can then be inserted into this space. This has the advantage that the lens is held securely when folding. However, a disadvantage is the complex construction of the cartridge and its complicated handling.
  • lenses made of hydrophobic material are increasingly being used again.
  • This has the advantage that they do not have to be stored in liquid prior to their use.
  • This makes it possible to load the cartridges or the injectors already in the factory with a lens in unfolded state, so that the previous tricky charging before surgery is no longer necessary.
  • the surgeon only needs to perform the folding process and if necessary - if not already present - to introduce the lubricating fluid. It is therefore an object of the present invention to provide a device for folding an intraocular lens, which avoids the disadvantages of the described known constructions completely or at least partially. If possible, one and the same device is also suitable for folding intraocular lenses of different diameters.
  • a further object is to show ways and means of how the lens can already be loaded on the production side into the device and is securely positioned after loading until the operation.
  • this is achieved in a device of the type mentioned in the fact that in the closed position of the devices, the cavity has side walls which extend at least in the upper part practically parallel to the axis of symmetry of the half shells, and that the upper wall is substantially perpendicular to the axis of symmetry.
  • This has the advantage that both lenses with a relatively large diameter and those of relatively small diameter when inserted into the. open device always come to lie with their edges in the area where an upper wall portion merges into a side wall. The lenses are thus always reliably seized, regardless of their diameter when folding. The same device is thus useful for lenses of different diameters.
  • the device for folding the lens can be used in various ways. It can be designed, for example, as a cartridge insertable into an injector without an injector nozzle.
  • the device can also be formed as a cartridge in one piece with an injector nozzle.
  • the device can also form part of an injector housing. It is thus possible to form the injector housing and device in one piece with or without an injector nozzle made of plastic.
  • a plug-in device for insertion into an opening in an injector is formed on the one of the half shells.
  • the plug-in device has as blocking means, for example struts with barbs on.
  • a wing is arranged at least on one of the half shells. With this wing or wings, the half-shells can be conveniently moved relative to each other to fold the lens. In the folded state of the device, the wings lie flat on each other. A snap closure may be provided to keep the device closed with the inserted and folded lens in this position.
  • the invention also relates to 'an injector having an injector housing and a longitudinally displaceable in the injector plunger for use with a cartridge designed as a device according to the invention.
  • This injector is characterized in that a displaceably mounted slide is arranged on the injector housing, with which after actuation of the cartridge and pre-loading of the lens operable to fold the lens wings can be blocked. By this slide, the two half-shells are blocked in a predetermined opening angle, in which the half-shells firmly hold the lens without deforming them.

Abstract

La présente invention concerne un dispositif permettant de plier une lentille intra-oculaire (33), lequel dispositif présente deux demi-coques (13, 15) qui sont reliées par une charnière (17) et qui peuvent être déplacées l'une par rapport à l'autre avec des pattes formées sur les demi-coques (13, 15) afin de plier la lentille intra-oculaire. Afin de pouvoir utiliser le même dispositif pour des lentilles de diamètres différents, les demi-coques présentent, à la place des rainures habituellement présentes jusqu'à présent pour détecter les bords de la lentille, une configuration particulière selon laquelle les parois latérales (35), lorsque le dispositif est observé à l'état fermé, s'étendent parallèlement à l'axe de symétrie (37), et les sections de paroi supérieures (39) s'étendent de manière pratiquement orthogonale aux parois latérales (35). Ainsi, même lorsque l'angle d'ouverture du dispositif est important, la lentille est maintenue de façon sûre avant le pliage, ce qui permet de charger préalablement en usine la lentille (33) dans un injecteur (51). Un dispositif se présentant sous forme de cartouche (11') comprend un dispositif d'emboîtement (41) conçu pour être emboîté dans le boîtier (45) d'un injecteur (51). Il est possible de bloquer les pattes (19) avec un coulisseau (57) qui présente un dispositif de blocage (59). Avant l'opération, il est possible de tirer le coulisseau vers l'arrière, de plier la lentille préalablement chargée par pivotement de la patte (19), puis de l'injecter.
