AI Technical Summary
Intraocular lenses can deform irreversibly when stored in a folded state for extended periods, which is a concern during cataract treatment where the lens needs to be folded and inserted through a small incision in the eye.
A packaging arrangement with a dual-state design for the injector, where the piston is locked in place during transport to prevent folding, and only unfolds when the packaging is switched to the use state, ensuring the lens remains unfolded and free of mechanical tension until insertion.
This design prevents irreversible deformation of the intraocular lens, simplifies the preparation process for cataract treatment by eliminating the need for additional steps, and ensures the lens is maintained in an optimal state for insertion, reducing the risk of damage.

Abstract
Description
[0001] Packaging arrangement with an injector for introducing an intraocular lens into the capsular bag of an eye
[0002] The invention relates to a packaging arrangement comprising a packaging and an injector for introducing an intraocular lens into the capsular bag of an eye.
[0003] During cataract treatment, a small incision is traditionally made in the cornea, large enough to allow the tip of an injector to be inserted through the incision into the eye. After the incision has been made in the cornea, the lens of the eye is crushed using a technique such as phacoemulsification and then suctioned out of the capsular bag. An intraocular lens is then inserted into the eye. The intraocular lens is folded so that it fits through the tip of the injector. The tip is inserted through the incision into the capsular bag, and the folded intraocular lens is pushed through the tip into the capsular bag by a plunger of the injector, where the intraocular lens unfolds and replaces the original lens. Before the injector can be used, the injector must be prepared.To do this, a plunger of the injector must be moved so far that the intraocular lens is moved from a storage position in which the intraocular lens is essentially free of mechanical stress to the tip of the injector, thus folding it. Moving the plunger and thus moving the intraocular lens from the storage position before cataract treatment is performed should be avoided, because storing the intraocular lens in a folded state for an extended period of time can lead to irreversible deformation of the intraocular lens.
[0004] The object of the invention is to provide a packaging arrangement comprising a packaging and an injector, wherein the packaging arrangement can prevent irreversible deformation of an intraocular lens arranged in the injector.
[0005] The packaging arrangement according to the invention comprises a package and an injector configured to insert an intraocular lens into the capsular bag of an eye. The injector comprises an injector housing with an injector opening, via which the intraocular lens can be displaced out of the injector in an insertion direction of the injector, a proximal end arranged remote from the injector opening, and a piston mounted in the injector housing so as to be longitudinally displaceable in the insertion direction and configured to displace the intraocular lens in a direction toward the injector opening. The package has a transport state and a use state and comprises a distal packaging part and a proximal packaging part, which is arranged differently relative to the distal packaging part in the transport state than in the use state.The packaging has a driver that is attached to the distal packaging part and coupled to the piston, so that by displacing the injector housing counter to the insertion direction relative to the distal packaging part, the piston can be displaced toward the injector opening. In the transport state, the displacement of the injector housing counter to the insertion direction relative to the distal packaging part is limited by the proximal packaging component. The packaging is designed such that by bringing the packaging from the transport state into the use state, the displacement of the injector housing counter to the insertion direction relative to the distal packaging part occurs or is enabled.
[0006] By limiting the displacement of the injector housing counter to the insertion direction in the transport state, the piston cannot displace the intraocular lens towards the injector opening. As a result, the intraocular lens cannot be folded in the transport state, which could lead to the intraocular lens becoming irreversibly deformed. Only when the packaging is brought from the transport state to the use state can the injector housing be displaced counter to the insertion direction. For example, this can be achieved by bringing the packaging from the transport state to the use state or by displacing the injector housing by hand counter to the insertion direction relative to the distal packaging part in the use state. Because the packaging has the driver, it is advantageously not necessary to provide an additional component on which the driver is arranged.To prepare the injector for cataract treatment, it is always necessary to remove the injector from the packaging. With the packaging arrangement according to the invention, this automatically results in the piston being displaced toward the injector opening. This advantageously eliminates a step in preparing the injector for cataract treatment.
[0007] It is preferred that the proximal packaging part has a base of the proximal packaging part and an elevation of the proximal packaging part, which elevation rises from the base of the proximal packaging part and is designed such that, in the transport state, the proximal end abuts against the elevation of the proximal packaging part, thus limiting the displacement of the injector housing counter to the insertion direction relative to the distal packaging part. Alternatively or additionally, it is conceivable that the proximal packaging part has a stop elevation that rises from the base of the proximal packaging part and is designed such that, in the transport state, a component of the injector different from the proximal end abuts against the stop elevation, thus limiting the displacement of the injector housing counter to the insertion direction relative to the distal packaging part.The component of the injector that differs from the proximal end can, for example, be a handle of the injector. The proximal packaging part is preferably pivotably attached to the distal packaging part, such that the packaging can be brought from the transport state into the use state by pivoting the proximal packaging part relative to the distal packaging part. In the use state, the displacement of the injector housing counter to the insertion direction relative to the distal packaging part is not limited by the elevation of the proximal packaging part and / or the stop elevation. This enables the displacement of the injector housing counter to the insertion direction relative to the distal packaging part in the use state.
[0008] As an alternative to pivotally attaching the proximal packaging part to the distal packaging part, it is preferred that the proximal packaging part be displaceably attached to the distal packaging part. The injector has a projection that projects transversely to the insertion direction from the injector, wherein the elevation of the proximal packaging part is formed and / or the proximal packaging part has a further elevation of the proximal packaging part, which is designed such that the elevation of the proximal packaging part and / or the further elevation of the proximal packaging part abuts the projection when the proximal packaging part is displaced away from the distal packaging part counter to the insertion direction, whereby the elevation of the proximal packaging part and / or the further elevation of the proximal packaging part carries the projection and thus the injector housing counter to the insertion direction.The projection can, for example, be a thumb rest of the injector, which is to be contacted by a thumb of a hand in order to displace the piston in the insertion direction. In another example, the projection can be a handle of the injector. It is preferred that the packaging has a bellows by means of which the proximal packaging part is displaceably arranged on the distal packaging part. Alternatively or additionally, the packaging preferably has a web with a first longitudinal end that is fastened to the distal packaging part, and a second longitudinal end that is arranged on the proximal packaging part, wherein the web is more curved in the transport state than in the use state. Thus, the packaging can be brought from the transport state into the use state by deforming the web.Alternatively or additionally, the distal packaging part and the proximal packaging part preferably form a sliding bearing by means of which the proximal packaging part is displaceably attached to the distal packaging part.
[0009] It is preferred that the base of the proximal packaging part and the elevation of the proximal packaging part define a proximal recess, wherein, in the transport state, the proximal end is arranged in the proximal recess. The proximal recess can be accessible in an assembly direction that is perpendicular to the insertion direction. Thus, for assembling the packaging arrangement, the injector can be inserted into the proximal recess in the assembly direction.
[0010] The distal packaging part preferably has a base of the distal packaging part and an elevation of the distal packaging part that rises from the base of the distal packaging part, wherein the base of the distal packaging part and the elevation of the distal packaging part delimit a distal recess in which, in the transport state, a distal end of the injector is arranged facing away from the proximal end. The distal recess can be accessible in the assembly direction. Thus, for assembling the packaging arrangement, the injector can be inserted into the distal recess in the assembly direction. It is preferred that the injector housing has a housing opening via which, in the transport state, the driver extends into the interior of the injector housing and is coupled there to the piston. In particular, the housing opening can be arranged at a distance from the injector opening.
[0011] The packaging assembly preferably comprises the intraocular lens, which, in the stored state, is arranged within the injector housing. In particular, the intraocular lens is arranged substantially free of mechanical stress and / or unfolded in the stored state.

[0022] Figure 11 is a representation of a detail II from Figure 8, wherein the piston and the further piston are in a coupling state.
[0023] As can be seen from Figures 2 to 4, a packaging arrangement 1 comprises a package 2 and an injector 3 configured to insert an intraocular lens 4 (see Figures 7 to 9) into the capsular bag of an eye. Figures 2 to 4 and 7 to 9 show that the injector 3 has an injector housing 9 with an injector opening 5 (see Figures 7 to 9), via which the intraocular lens 4 can be displaced out of the injector 3 in an insertion direction 6 of the injector 3. In addition, the injector 3 has a proximal end 15 arranged facing away from the injector opening 5 (see Figures 1 to 9) and a piston 7 (see Figures 7 to 9) which is mounted in the injector housing 9 so as to be longitudinally displaceable in the insertion direction 6 and is designed to displace the intraocular lens 4 in a direction towards the injector opening 5, in particular to displace it in the insertion direction 6 towards the injector opening 5.The packaging 2 has a transport state (see Figures 1, 2, 4 and 5) and a use state (see Figure 3) and comprises a distal packaging part 21 and a proximal packaging part 22, which is arranged differently relative to the distal packaging part 21 in the transport state than in the use state. The packaging 2 has a driver 20 (see Figures 1 to 5 and 7 to 9) which is attached to the distal packaging part 21 and coupled to the piston 7, so that by displacing the injector housing 9 counter to the insertion direction 6 relative to the distal packaging part 21, the piston 7 can be displaced towards the injector opening 5. In the transport state, the displacement of the injector housing 9 counter to the insertion direction 6 relative to the distal packaging part 21 is limited by the proximal packaging component 22.The packaging 2 is designed such that, by bringing the packaging 2 from the transport state into the use state, the displacement of the injector housing 9 relative to the distal packaging part 21 counter to the insertion direction 6 occurs (see Figures 4 to 6) or is enabled (see Figures 1 to 3). It is conceivable that the packaging arrangement 1 comprises the intraocular lens 4, which is arranged within the injector housing 9 in the storage state. In particular, the intraocular lens 4 can be arranged substantially free of mechanical stress and / or unfolded in the storage state.
[0024] Figures 2 to 4 show that the injector 3 can have a thumb rest 11, which can be contacted by a thumb of a hand when the piston 7 is displaced by the hand in the direction toward the injector opening 5. The thumb rest 11 can form the proximal end 15. Furthermore, it can be seen from Figures 2 to 4 that the injector 3 can have a handle 10, which can be grasped by fingers of the hand other than the thumb when the piston 7 is displaced. The handle 10 can be arranged in the insertion direction 6 at a distance from the proximal end 15 and at a distance from the injector opening 5.
[0025] Figures 1 to 6 show that the proximal packaging part 22 can have a base 30 of the proximal packaging part 22 and a protrusion 32 of the proximal packaging part 22, which protrudes from the base 30 of the proximal packaging part 22 and is designed such that in the transport state the proximal end 15 abuts against the protrusion 32 of the proximal packaging part 22 and thus the displacement of the injector housing 9 opposite the insertion direction 6 relative to the distal packaging part 21 is limited.Alternatively or additionally, it is conceivable that, as shown in Figures 4 and 6, the proximal packaging part 22 has a stop elevation 36 which rises from the base 30 of the proximal packaging part 22 and is designed such that, in the transport state, a component of the injector 3 different from the proximal end 15 abuts against the stop elevation 36 and thus limits the displacement of the injector housing 9 counter to the insertion direction 6 relative to the distal packaging part 21. The component of the injector 3 different from the proximal end 15 can be, for example, the handle 10.
[0026] Figures 1 to 3 show that the proximal packaging part 22 is pivotably attached to the distal packaging part 21, so that the packaging 2 can be brought from the transport state shown in Figures 1 and 2 into the use state shown in Figure 3 by pivoting the proximal packaging part 22 relative to the distal packaging part 21. In the use state, the displacement of the injector housing 9 counter to the insertion direction 6 relative to the distal packaging part 21 is not limited by the elevation 32 of the proximal packaging part 22 and / or the stop elevation 36. Figures 1 to 3 show that the packaging 2 can have a film hinge 24, by means of which the proximal packaging part 22 is pivotably attached to the distal packaging part 21. However, other joints are also conceivable, such as a joint in which a pin engages in a sleeve and is rotatably mounted in the sleeve.After the packaging 2 has been pivoted from the storage state to the use state, the displacement of the injector housing 9 opposite to the insertion direction 6 relative to the distal packaging part 21 is possible because the elevation 32 of the proximal packaging part 22 no longer blocks the proximal end 15 and / or the stop elevation 36 no longer blocks the component different from the proximal end 15, in particular the handle 10, see Figure 3.
[0027] Figures 4 to 6 show that the proximal packaging part 22 can be attached to the distal packaging part 21 in a displaceable manner, in particular longitudinally displaceable counter to the insertion direction 6, and that the injector 3 can have a projection that protrudes from the injector 3 transversely to the insertion direction 6. The elevation 32 of the proximal packaging part 21 can be designed such that the elevation 32 of the proximal packaging part 22 abuts against the projection when the proximal packaging part 22 is displaced counter to the insertion direction 6 away from the distal packaging part 21 and carries the projection and thus the injector housing 9 counter to the insertion direction 6. The projection can be, for example, the thumb rest 11.Alternatively or additionally, the proximal packaging part 22 can have a further elevation 33 of the proximal packaging part 22, which is designed such that the further elevation 33 of the proximal packaging part 22 abuts against the projection when the proximal packaging part 22 is displaced counter to the insertion direction 6 away from the distal packaging part 21 and carries the projection and thus the injector housing 9 counter to the insertion direction 6. In this case, the projection can be formed, for example, by the handle 10, see Figure 4. Alternatively or additionally, in this case the projection can be formed by the thumb rest 11.
[0028] The packaging 2 can have a bellows 25 (see Figure 4), by means of which the proximal packaging part 22 is displaceably arranged on the distal packaging part 21. In the transport state, the bellows 25 can be in its compressed state, and in the use state, the bellows 25 can be in its stretched state. Figure 5 shows that the packaging 2 can have a web 27 with a first longitudinal end attached to the distal packaging part 21 and a second longitudinal end arranged on the proximal packaging part 22, wherein the web 27 is more curved in the transport state than in the use state.It is also conceivable for the packaging 2 to have a further web 28 with a first longitudinal end attached to the distal packaging part 21 and a second longitudinal end arranged on the proximal packaging part 22, wherein the further web 28 is more curved in the transport state than in the use state. For example, by grasping the distal packaging part 21 with one hand and the proximal packaging part 22 with another hand and then moving both hands away from each other, the web 27 and optionally the further web 28 can be deformed and the packaging can be brought from the storage state into the use state.
[0029] Figure 6 shows that the distal packaging part 21 and the proximal packaging part 22 can form a sliding bearing, by means of which the proximal packaging part 22 is displaceably attached to the distal packaging part 21. For example, the packaging 2 can have a slider elevation 41 that delimits an interior space and a slider 43 that is arranged so as to be longitudinally displaceable in the interior space. For example, the slider elevation 41 can be arranged on the proximal packaging part 22 and the slider 43 can be arranged on the distal packaging part 21, as shown in Figure 6. Alternatively, the slider elevation 41 can be arranged on the distal packaging part 21 and the slider 43 can be arranged on the proximal packaging part 22. In addition, it is conceivable for the packaging 2 to have a further slider elevation 42 that delimits a further interior space and a further slider 44 that is arranged in the further
[0030] Interior is arranged so as to be longitudinally displaceable. The distal packaging part 21 can have a pin 47 and optionally a further pin 48, which abut the proximal packaging part 22 in the stored state and thus limit displacement of the proximal packaging part 21 in the insertion direction 6 relative to the distal packaging part 21, see Figure 6. It is conceivable for the proximal packaging part 22 to have a respective recess 45, 46 for each of the pins 47, 48. Alternatively, the proximal packaging part 22 can have a pin and optionally a further pin, which abut the distal packaging part 22 in the stored state and thus limit displacement of the proximal packaging part 21 in the insertion direction 6 relative to the distal packaging part 21. It is conceivable for the distal packaging part 21 to have a respective recess for each of the pins.
[0031] Figures 1 to 6 show that the base 30 of the proximal packaging part 22 and the elevation 32 of the proximal packaging part 22 can define a proximal recess 35, with Figures 2 and 4 showing that, in the transport state, the proximal end 15 can be arranged in the proximal recess 35. The proximal recess 35 can be accessible in an assembly direction that is arranged perpendicular to the insertion direction 6. Thus, for assembling the packaging arrangement 1, the injector 3 can be introduced into the proximal recess 35 in the assembly direction.Figures 1 to 6 also show that the distal packaging part 21 can have a base 29 of the distal packaging part 21 and a protrusion 31 of the distal packaging part 21, which protrudes from the base 30 of the distal packaging part 21, wherein the base 29 of the distal packaging part 21 and the protrusion 31 of the distal packaging part 21 delimit a distal recess 34, in which, in the transport state, a distal end 16 of the injector 3 is arranged facing away from the proximal end 15. The distal recess 34 can be accessible in the assembly direction. Thus, for assembling the packaging arrangement 1, the injector 3 can be inserted into the proximal recess 35 in the assembly direction. It is conceivable that the elevation 31 of the distal packaging part 21 forms a press fit for an end region of the injector 3, wherein the end region has the distal end 16.For example, the press fit can be designed such that a force of less than 5 N is required to remove the end portion from the packaging 2. Figures 7 to 9 also show that the injector opening 5 can be arranged at the distal end 16.
[0032] Figures 7 to 9 show that the injector housing 9 can have a housing opening 12, through which, in the transport state, the driver 20 extends into the interior of the injector housing 9 and is coupled there to the piston 7. The housing opening 12 can be arranged separately from the injector opening 4.
[0033] The distal packaging part 21 may have a groove 23 with an undercut (see Figures 1 to 4 and 6) into which the driver 20 is inserted in order to fasten the driver 20 to the distal packaging part 21. Alternatively, the driver 20 may be glued and / or welded to the distal packaging part 21 (see Figure 5) and / or the driver 20 may be formed as a projection from the distal packaging part 21.
[0034] Figures 7 to 9 show that the injector 3 can have a further piston 8, which is mounted in the injector housing 9 so as to be longitudinally displaceable, in particular in the insertion direction 6. The piston 7 and the further piston 8 can either be in a decoupling state (see Figure 7), in which the piston 7 and the further piston 8 are longitudinally displaceable relative to one another, or in a coupling state (see Figures 8 and 9), in which the piston 7 and the further piston 8 are rigidly coupled to one another in the insertion direction 6 and the total longitudinal extent of the piston 7 and the further piston 8 in the insertion direction 6 is longer than in the decoupling state. Figure 7 shows the injector 3 in the decoupling state.By displacing the piston 7 by displacing the injector housing 9 against the insertion direction 6 relative to the distal packaging part 21 in the direction of the injector opening 5, the piston 7 and the further piston 8 are brought into the coupling state and the intraocular lens 4 can be brought into a folded state, see Figure 8. Subsequently, when the injector 3 is arranged outside the packaging 2, the piston 7 and the further piston 8 can be displaced together in the insertion direction 6 and the intraocular lens 4 can thus be displaced out of the injector 3 via the injector opening 5, see Figure 9. The thumb rest 11 can be attached to the further piston 8 for this purpose. By providing the further piston 8, the injector 3 can be shorter than if only the piston 7 were provided.
[0035] As can be seen from Figures 2 and 3, the injector 3 can have a locking mechanism 17 that has a locking state in which a displacement of the further piston 8 in the insertion direction 6 is limited, and an unlocking state in which the displacement of the further piston 8 in the insertion direction 6 is not limited. For example, the locking mechanism 17 can have a ring that is arranged externally on the further piston 8 and outside the injector housing 9 and that is configured to abut against the injector housing 9 in the locking state. To bring the locking mechanism 17 into the unlocking state, the ring can be removed from the further piston 8.
[0036] Figures 7 to 11 show that the further piston 8 can have a cavity and the piston 7 can be arranged so as to be longitudinally displaceable in the cavity in the uncoupling state. Figures 10 and 11 show that the piston 7 can have a piston projection 13 and the further piston 8 can have a piston recess 14, wherein the piston projection 13 is configured to be arranged outside the piston recess 14 when the piston 7 and the further piston 8 are in the uncoupling state (see Figure 10), and is configured to engage in the piston recess 14 to bring the piston 7 and the further piston 8 into the coupling state (see Figure 11) when the piston 7 is displaced towards the injector opening 5.Figures 10 and 11 also show that the piston 7 can have a further piston projection 13a and the further piston 8 can have a further piston recess 14a, wherein the further piston projection 13a is designed to be arranged outside the further piston recess 14a when the piston 7 and the further piston 8 are in the uncoupling state (see Figure 10), and is designed to engage in the further piston recess 14a to bring the piston 7 and the further piston 8 into the coupling state (see Figure 11) when the piston 7 is displaced in the direction of the injector opening 5.
[0037] It is conceivable for the packaging 2 to have a film (not shown in the figures) that is attached to the distal packaging part 21 and the proximal packaging part 22 in the storage state and, together with the distal packaging part 21 and the proximal packaging part 22, forms a closed packaging cavity in which the injector 3 is arranged. After the film has been removed from the distal packaging part 21 and the proximal packaging part 22, it is conceivable to wet the intraocular lens 4 with a physiological saline solution and / or an ophthalmic viscoelastic device (OVD). This can be done, for example, via the housing opening 12 or via an opening in the injector housing 9 that is different from the housing opening 5. After that, it is conceivable to bring the packaging 2 from the transport state into the use state. List of reference symbols
