Definitions

  • the present invention relates to an injector for intraocular lenses and a stamp of an injector suitable for ejecting a lens from the injector.
  • an ocular incision of typically 2 to 4 mm is made through which the natural lens of the eye is first removed and then the implant is inserted.
  • the folded artificial lens is inserted through the incision into the capsular bag. As soon as the folded lens is inserted into the capsular bag, it unfolds back into its original shape.
  • the artificial lenses customary today consist of an optical lens body and usually two or more haptics projecting peripherally from this transversely to the optical axis of the Linsenkör pers, which serve in the capsular bag as position springs for the lens body.
  • two haptics which are arranged opposite one another on the lens body, spiral in the same direction from the lens body. This haptic form, which is most frequently used worldwide, is called open c-loop haptic in the laughing industry.
  • lens carriers or cartridges and injectors are, for example, from US Pat. No. 6,267,768, US Pat. No. 5,810,833, US Pat. No. 6,283,975, US Pat. No. 6,248,111, US Pat. No. 4,681,102, US Pat. No. 5,582,614, US Pat. No. 5,499,987, US Pat 5 947 975, US 6 355 046 and EP 1 290 990 B1, as well as the disclosures US 2004/0199174 A1, EP 1 905 386 A1 and WO 03/045285 A1 are known.
  • the cartridge which is designed as a splitting device for the lens, and the injector nozzle are separate parts.
  • the cartridge can be pushed into the injector housing, whereupon the injector nozzle can be screwed onto the front of the injector housing.
  • the cartridge consists in one piece of a holder and an injector nozzle.
  • Intraocular lenses are packaged sterile by the manufacturer and, if necessary, supplied in a fluid bath. Depending on the lens material, storage in a liquid may be necessary to protect the lens from drying out. During the operation, the lens must be removed from the packaging in the sterile area and inserted or loaded into the loading device of an injector or directly into an injector using the cartridge supplied.
  • the lenses are very sensitive structures which can easily be damaged when reloading into a cartridge, splitting or ejecting from the injector nozzle. The risk of damage is particularly great for the haptics that surround the optical part of the lens.
  • WO 03/045285 A1 shows a method for inserting an intraocular lens into the capsular bag of the eye, in which an overpressure is generated in order to eject a lens floating in a lubricant from the injector nozzle.
  • a compressible and, if necessary, elastic piston adapts continuously to the nozzle channel which narrows towards the front.
  • the lens continues to fold on its way and has a very small diameter at the end of its way. Due to the compressibility of the piston, the end of the nozzle channel can be kept very narrow, so only a very small incision is necessary.
  • a set for executing the method contains a lens carrier and a lens. The lens is in a tension-free state in the lens carrier.
  • Lens and lens carrier are preferably carried by a holder and packed sterile ver until use in a pack, in the case of a hydrophilic lens in a liquid that protects the lens from drying out.
  • the lens carrier and the lens stored in it are removed from the pack, inserted into the injector and folded.
  • a lubricating liquid is poured in through the channel. The lens can now be injected into the capsular bag of the eye to be treated.
  • injector systems which use completely different pistons.
  • This also includes non-planar piston tips or piston pistons, as shown in EP1'832'247B1, US2003195522A1, W09726844A2 and US6W520B1 and US5582614A.
  • punches often serve to hold the lens, i. in particular to pick up the lens body like a shovel (especially in EP1'832'247B1, US6W520B1, US2003195522A1,

  • the laid-open specification US 2008/0058830 A1 discloses a system for transferring an intraocular lens (IOL) from a lens container into the loading chamber of an injector and then from the injector into the patient's eye.
  • the haptics in the lens container are preferably folded over the optics and held in this position during the transfer of the intraocular lens into the loading chamber.
  • a shuttle is provided for the splitting and the transfer, which grips and manipulates at least the rear haptics.
  • a piston is provided which passes through the shuttle in order to push the lens stored in front of the shuttle through the injector nozzle.
  • systems for pre-folded lenses and systems for non-pre-folded lenses can be distinguished in the prior art.
  • the lenses are only folded during the pushing process for injection.
  • systems are used in particular in which the lens is loaded into a loading chamber from the rear, still in the deformed state or unfolded (as shown, for example, in US Pat. No. 5,810,833).
  • the rear opening into which the lens is inserted is at least as wide and high as the lens itself. If a piston with deformable Tip (usually made of silicone or TPE) is used, the plunger tip must fill the entire volume of the rear opening so as not to run the risk of running over the rear of the two haptics and thus becoming trapped.
  • the lens When the at least two half-shells are closed, the lens is folded before and is in the loading chamber in the folded state.
  • the pre-folding of the lens including the haptics by closing the winged cartridge reduces the internal volume of the closed winged cartridge to almost half and thus enables the use of smaller deformable piston tips, which cause smaller incision forces with the same internal diameter of the cartridge tip, or the use of smaller cartridge insides with the same incision force - cause diameter and thus smaller incisions.
  • the disadvantage of these systems for pre-folding the lenses is that in particular the lens cover, and in the worst case even the optics, can be pinched between the two wings when the two wings of the cartridge are closed. Jammed haptics usually tear off as the lens is advanced further, which amounts to a total loss of the lens.
  • a winged cartridge for receiving an intraocular lens in a loading chamber is presented.
  • the winged cartridge is formed by a first and a second half-shell, each half-shell having a winged handle along its length.
  • the two half-shells are articulated to each other on the wingless longitudinal side via a first joint and can be moved relative to one another from an open position to a closed position by means of the first joint, the two half-shells being one in the closed position Form the discharge channel for an interocular lens.
  • a jamming of the at least before their haptics when closing is prevented here by a cover member.
  • the front haptic either rests in an arc on the optic or even rests on the optic and is enclosed by the optic when the lens is folded. Since the latter is associated with an increased lens volume and therefore an enlarged incision size and often haptics on the optic stick to it, it is preferred in most cases to only place the front haptic against the optic, but not on the optic.
  • WO2015 / 070358 describes a loading chamber with an integrated stopper at the end of the loading chamber.
  • the force effect should be transferred to the optics and the lens should be pushed in the direction of advance until the front haptic hits the stopper and the optic rests against the front haptic.
  • this process does not work fully reproducible and universally for all lens materials and haptic designs. Since the piston tip only hits the rear, freely movable haptic and the force is only indirectly transferred to the optic, it can happen that the rear haptic is pressed heavily onto the optic without the optic itself moving. In particular, this can easily happen if the lens optics sticks something to the loading chamber wall, which is often the case with so-called preloaded lenses.
  • Pre-charged lenses are those lenses in which the lens is already inserted into the injector at the factory and is stored in it for the life of the product. If this happens that the rear Hapük is pressed strongly against the optics, which If, for its part, it may not move or move only insufficiently, this has the consequence that the rear haptic is severely deformed by excessive pressure and the front haptic is not even pressed against a possible stopper, whereupon the front haptic again emerges stretched out of the loading chamber.
  • the lens with the c-loop handle can rotate a few degrees around its center of the optics in the rest position within the loading chamber. This rotation is greater, the shorter the c-loop handles are, since they limit the rotation by stopping against the loading chamber wall. Even if the length of the lens is limited in the loading chamber, the rotation of the lens about its center point (i.e. about its optical axis) is possible within the stated limits. Correspondingly, the alignment of the lens and its haptics also differ when it emerges from the cartridge into the eye. The surgeon often has to counteract this by carefully turning the injector, which repeatedly poses problems, especially for inexperienced surgeons.
  • Another problem can be that when the loading chamber is closed, ie while the lens is being folded, the rear haptic stretches backwards and wraps around the plunger. This happens, for example, when a rear haptic points backwards, ie towards the ram (eg due to the shape of the haptic itself or due to unfavorable manipulation when inserting the lenses into the loading chamber).
  • a faulty injection is to be expected, since the rear haptics become more and more wedged between the stamp and the cartridge wall as the lens is further advanced.
  • a device which folds an intraocular lens without it being damaged when it is folded and / or injected. Furthermore, a device is to be provided which is optimized with regard to the manipulation steps for preparing the lens and injector. In particular, as few manipulation steps as possible should be necessary, which must be carried out after delivery of the lens and injector or which must be carried out immediately before the surgical intervention on the device. In addition, a device is to be provided which manages with as few additional components as possible, in the best case even without any additional components in relation to the injectors and thus the above-mentioned Goal achieved without generating additional costs.
  • the object is preferably to be achieved in such a way that no additional parts, no additional costs and no additional application steps are associated with it.
  • the system or the device should be suitable for fully-preloaded, semi-preloaded and non-preloaded lenses.
  • the system should also work in conjunction with wing cartridges, in particular wing loading chambers that can be inserted into injector housings. Another aim is to create a device which only requires small incisions in the eye in use.
