Including protrusions extending toward it.
The present invention relates to a lens injection device for implanting a deformable intraocular lens into the eye. The lens injecting device includes a lens delivery passage through the device, the passage being accessible by a laterally hinged lid.
In one preferred embodiment, the lens injection device is a one-piece or one-piece device (ie, a device without a lens cartridge). For example, a lens injection device includes a housing having an injection tip and a passage provided therethrough, a movable plunger disposed within the housing, and a laterally hinged along the side of the housing. The lateral hinged lid allows the deformable intraocular lens to be loaded into the lens delivery passageway from the side of the housing through the opening or window when it is opened. , Seal the opening or window when the laterally hinged lid is closed.
In another embodiment, the lens injecting device is a two-piece or two-part device comprising 1) a lens injecting device including a lens cartridge receiving portion and 2) a lens cartridge. For example, a lens infusion device includes a housing, a lens cartridge receptacle provided at one end of the housing, and a movable plunger disposed within the housing. The lens cartridge is, for example, a one-piece or one-piece device that includes a lens holding portion connected to a nozzle portion, and the lens holding portion has a lid with a lateral hinge. Once the deformable intraocular lens is loaded inside the lens cartridge, the lens cartridge is then loaded into the lens cartridge receptacle of the lens injection device.
The structure of the laterally hinged lid used in the lens injecting device according to the present invention places the hinge transversely to the direction of the lens delivery passage. Specifically, the hinge axis is not parallel to the longitudinal axis of the lens delivery passage. Preferably, the hinge axis is located at an angle of 45 to 90 degrees with respect to the longitudinal axis of the lens delivery passage. In particular, in embodiments where the hinged lid is used to fold the deformable intraocular lens into the lens delivery passage, the laterally hinged lid contacts the deformable intraocular lens. Most preferably, the axis of the hinge is at an angle of 90 degrees with respect to the longitudinal axis of the passage so that the portion that pushes the lens into the lens delivery passage is aligned with the lens delivery passage.
In a preferred embodiment, the lens delivery passage is linear, but a curved arrangement can also be used. Further, the lens delivery passage may have undulations (eg, including one or more grooves) as the deformable intraocular lens is further folded as the lens is moved along or through the lens delivery passage. obtain). Further, the lens delivery passage may taper inward in the direction in which the deformable intraocular lens advances through the lens delivery passage.
Preferably, the laterally hinged lid is configured to substantially seal the lens delivery passage when the lid is closed, thereby pushing the deformable intraocular lens through the lens delivery passage. Sometimes the deformable intraocular lens is prevented from leaving the passage. In some embodiments, the laterally hinged lid applies little or no compressive force to the deformable intraocular lens loaded in the lens delivery passage when it is fully closed. Absent. In other embodiments, the laterally hinged lid intentionally applies a compressive force to the deformable intraocular lens loaded in the lens delivery passage when it is fully closed. .
In other embodiments, the laterally hinged lid does not seal the lens delivery passage; instead, the lid folds the lens into the lens delivery passage when the lid is being closed. Used. If the deformable intraocular lens is fully folded and trapped inside the lens delivery passage, the deformable intraocular lens can be positioned in a laterally hinged lid, for example by a plunger tip. It can be advanced through to the front part of the lens injection device. The front portion of the lens injecting device can have a completely closed lens delivery passage section having an inwardly tapered shape or a shape that bends the lens, and the shape of the passage section is determined by the deformable intraocular lens. A radially inward compression force is applied to the deformable intraocular lens by the inner wall of the lens delivery passage as it is moved forward through the passage.
The laterally hinged lid is preferably configured to remain closed when closed, and more preferably securely locks when closed (e.g., releasably locked, Allow re-opening for lens inspection or re-use of lens injecting device, or permanently lock to prevent re-opening and reuse). In some preferred embodiments, the inner surface of the lateral hinged lid serves as the inner surface of the lens delivery passage and is preferably adjacent to the remaining inner wall of the lens injecting device. In addition, the inner surface of the lateral hinged lid has a relief (eg, with at least one groove, protrusion, or pattern of surfaces with multiple reliefs) and the lateral hinged lid. Folding of the deformable intraocular lens can be facilitated when closing and / or advancing the deformable intraocular lens through the lens delivery passage.
In a preferred two- or two-part device, the laterally hinged lens cartridge is kept closed once inserted into the lens receiver of the lens injection device. For example, the cylindrical portion of the housing of the lens infusion device serves as a lens cartridge receiving portion, and when the lens cartridge is inserted into the lens cartridge receiving portion, the clamping force of the cylindrical portion causes the lateral hinge to Keep the attached lens cartridge closed.
In one preferred embodiment, the laterally hinged lid provides a deformable intraocular lens with the end of the deformable intraocular lens held by the side of the opening through the side of the housing. It includes a protrusion for pushing downward, which folds the deformable intraocular lens into the lens delivery passage as the lateral hinged lid is closed.
In another preferred embodiment, the deformable intraocular lens injection device includes a lens injection device and a lens cartridge receiver. The lens cartridge of the present invention has a lens holding part connected to the nozzle part. At the same time, the lens holding portion and the nozzle portion define a lens delivery passage, and an intraocular lens that can be deformed through the passage is inserted into the eye capsule. The longitudinal axis of the lens cartridge is substantially parallel to the lens delivery passage.
The lens holding part of the lens cartridge of the present invention includes a movable wall part movably connected to the fixed wall part. The movable wall moves around an axis that is not parallel to the longitudinal axis of the lens cartridge. In the most preferred embodiment of the present invention, the movable wall portion pivots about a lateral hinge that connects the movable wall portion to the fixed wall portion. In the most preferred embodiment, the lateral hinge is configured such that there is a plane that is perpendicular to the axis of the lateral hinge and that includes the longitudinal axis of the lens cartridge.
The lens cartridge of the present invention also includes means for releasably locking the lens cartridge within the lens injecting device. In the most preferred embodiment of the present invention, an extension is included on the lens holding portion of the lens cartridge. The extension engages with an L-shaped slot in the lens injection device to releasably lock the lens cartridge into the device.
In use, the fixed wall of the lens cartridge is gripped by the user's first hand. With the second hand, the user opens the lens cartridge by pushing up the movable wall with the lateral hinge as an axis to expose a substantial portion of the lens delivery path of the lens cartridge. A deformable intraocular lens is disposed on the exposed lens delivery passage when the lens cartridge is in an open state.

When pushing with the thumb of the user, the plunger 18 is pushed forward against the spring force provided by the spring 31.
A closed arrangement of the first preferred lens cartridge 14 is shown in FIGS. 2A and 2B, and an open arrangement is shown in FIGS. 3A and 3B. Details of the longitudinal sectional view of the lens cartridge 14 are shown in FIG.
The lens cartridge 14 includes a lens holding part 32 connected to the nozzle part 34. Preferably, the lens cartridge 14 is a one-piece structure, for example, manufactured by plastic injection molding of plastic (eg, polyethylene) that can be autoclaved. However, the lens holding part 32 and the nozzle part 34 can be manufactured and combined as independent parts.
The lens cartridge 14 includes an extension 36 that is installed approximately perpendicular to the longitudinal axis of the lens cartridge 14 to cooperate with a lateral slot 26 in the conical section 22. When the lens cartridge 14 is loaded into the lens cartridge receiving portion 16 of the conical portion 22, the extension portion 36 is inserted into the vertical slot 24. The lens cartridge 14 is then inserted into the lens injection so that the extension 36 is inserted into the lateral slot 26 to provide a "plug" type connection that locks between the lens injection device 12 and the lens cartridge 14. Rotated relative to device 12. This coupling arrangement ensures that the lens injection device 12 and the lens cartridge 14 do not move relative to each other during use of the lens injection device 10.
The lens cartridge 14 is configured to open and close to load a deformable intraocular lens into a lens delivery passage through the lens cartridge 14. 1-3, the lens holding part 32 includes a fixed wall part 38 connected to the movable wall part 40 by a lateral hinge 42. The hinge 42 is considered “lateral” because the axis of the hinge is approximately perpendicular to or across the longitudinal axis of the lens cartridge 14.
The lens cartridge 14 includes a lens delivery passage 44 that extends through the lens holding portion 32 and into the nozzle portion 34. The rear end 46 of the lens cartridge 14 includes an opening 48 that serves as an inlet to the lens delivery passage 44 (eg, an inlet for the plunger tip), and the front end 50 of the lens cartridge 14 is an outlet from the lens delivery passage 44. The nozzle tip 50 is provided with an opening 52 that serves as an outlet (eg, an outlet for a deformable intraocular lens).
The movable wall portion 40 includes a protrusion 56 that extends toward the inside of the lens delivery passage 44. The projecting portion 56 is used to fold the center portion of the intraocular lens that can be deformed when the movable wall portion 40 is closed into the lens delivery passage 44. Specifically, deformable intraocular lenses L (For example, a plate type IOL (intraocular lens) or a three-part type), as shown in FIG. An intraocular lens that can be deformed to be placed can be loaded into the lens cartridge 14 by placing it in a flat configuration.
When the movable wall 40 is closed (for example, when the user pushes the movable wall 40 with the index finger of the other hand while supporting the fixed wall 38 between the thumb and index finger of one hand) The protrusion 56 extending in the inner direction is a deformable intraocular lens. L In contact with the center of As the movable wall 40 is further closed, the protrusion 56 becomes deformable intraocular lens. L Is pushed downward into the lens delivery passage 44. Deformable intraocular lens L Is fully loaded into the lens delivery passage, the deformable intraocular lens is folded or bent into contact with the inner surface of the fixed wall 38 (FIG. 4) and at the same time the deformable intraocular lens. L The opposite edges are bent upward and enter the opposite groove 60 provided on the inner surface of the movable wall 40.
The hinge 42 is an “integral” hinge that is molded into the plastic lens cartridge 14 to reduce the wall thickness and allow bending. Preferably, the wall rubs the surface of the deformable intraocular lens, particularly the lens portion, as the dimensions of the lens delivery passage 44 are accurately maintained and the deformable intraocular lens advances through the lens delivery passage 44. Or the thickness from the outer surface of the lens cartridge 14 is made thin so that the edge which may be damaged does not arise. Alternatively, the movable wall 40 and the rest of the lens cartridge are independent component assemblies combined with a hinge (eg, snap-fit interlocking member or hinge pin design).
In the first specific example of the lens cartridge 14 shown in FIG. 6, the groove 60 extends only along the length of the movable wall portion 40. However, the groove 60 can extend further forward along the lens delivery passage 44 extending through the lens holding portion 32, or can extend into the lens delivery passage of the nozzle portion 34. Further, instead of a set of grooves 60, a single turn groove (ie, spiral form) is used to keep one end of the lens bent around the rest of the lens so that the lens passes through the lens delivery path. The deformable intraocular lens can be wound more firmly as it moves forward.
The protrusion 56 shown in FIG. 6 is tapered downward in the direction in which the deformable intraocular lens is advanced. Alternatively, the protrusions 56 can be modified so that they are not tapered or taper in the opposite direction. Further, unlike the inclined linear structure shown in FIG. 6, the lower surface of the protruding portion 56 has a curved (for example, concave, convex) continuous shape, a discontinuous shape, or a combination of these shapes. can do.
Deformable intraocular lens L Deformable intraocular lens L Are loaded into the lens cartridge 14 by placing them as shown in FIG. 3A. Specifically, deformable intraocular lenses L Is passed and lies on the edge 58 (FIG. 3B). Next, the user pushes down the movable wall portion 40 while holding the portion other than the movable wall portion 40 of the lens cartridge 14, thereby pushing the central portion of the intraocular lens L in which the projecting portion 56 can be deformed downward to deform it. Possible intraocular lens L Is bent along the center of the lens and placed in the lens delivery passage 44. The lens cartridge 14 is then loaded into the lens cartridge receptacle 16 of the lens injection device 12 by aligning the extension 36 of the lens cartridge 14 with the longitudinal slot 24 of the lens injection device 12. The lens cartridge 14 is pushed backwards and then rotated so that the extension 36 locks in the lateral slot 24.
