Description

[0001] A CARTRIDGE INJECTOR SYSTEM WITH A SAFETY ELEMENT

[0002] TECHNICAL FIELD

[0003] The invention relates to a cartridge injector system for use in the implantation of at least one lens in the eye, comprising at least one cartridge for folding said lens, at least one folding part on said cartridge to allow bending of the lens, at least one button movable towards the cartridge to at least partially round said folding part, and at least one piston to allow the bent lens to be pushed out through at least one discharge end.

[0004] PRIOR ART

[0005] The intraocular lens treatment is a treatment method used in the eye disorders such as cataract. This method is based on the principle of replacing the natural lenses in the eye with the artificial, synthetic lenses produced with special technology. The lens here is a highly transparent, light-permeable structure inside the eye. They have very important functions such as refracting the light coming into the eye and transmitting it to the retina, allowing the eye to see objects at any distance.

[0006] In some eye disorders, especially cataract, the lens that has lost its transparency is removed and replaced with an intraocular lens made of foldable polymer material. The lens placement is performed with the cartridge injector systems. The intraocular lenses are folded and implanted into the eye. Various methods, such as rolling or folding, are used for implantation of the lenses into the eye. The most popular of these methods are the cartridge injector systems, which fold the lenses and push them into the eye with a soft-tipped piston.

[0007] The application TR2023 / 009089, known in the literature, relates to a cartridge injection system that prevents controlled bending of intraocular lenses during implantation and deformations due to lack of smooth movement within the system, and eliminates technical problems caused by contact with the coated area or lubricant materials. The novelty of the invention relates to a cartridge injection system comprising the arrangements for achieving controlled bending of intraocular lenses during implantation and preventing contact with areas containing coated or lubricating materials. The intraocular lenses are artificial lenses that replace the natural lens in the eye. These lenses are usually used during cataract surgery. However, it is known that the intraocular lenses may encounter the undesired problems in some cases. One of these problems is folding or slipping of the intraocular lens. Folding or slipping of intraocular lenses can be caused by problems within the capsule in which the lens is inserted, usually during surgery. Inadequate fixation of the lens may cause the lens to move over time if the lens is not properly fixed or inserted.

[0008] Such problems are usually tried to be carefully controlled during surgery, but can occur in rare cases. If the intraocular lens folds or slips, the patient symptoms may include blurred vision, flashes of light or eye pain. Such cases are usually evaluated by the doctor and revision surgery may be considered if necessary. Such problems are usually successfully corrected, but each case may differ from patient to patient.

[0009] As a result, all the above-mentioned problems have made it necessary to realize a novelty in the relevant technical field.

[0010] SUMMARY OF THE INVENTION

[0011] The present invention relates to a cartridge injector system to eliminate the above- mentioned disadvantages and bring the new advantages to the relevant technical field.

[0012] An object of the invention is to provide a cartridge injector system for use in the lens implantation, which reduces lens folding problems and can be safely transported.

[0013] In order to accomplish all the objects mentioned above and to be revealed from the detailed description below, the present invention is a cartridge injector system for use in the implantation of at least one lens in the eye, comprising at least one cartridge for folding said lens, at least one folding part on said cartridge to allow bending of the lens, at least one button movable towards the cartridge to at least partially round said folding part, and at least one piston to allow the bent lens to be pushed out through at least one discharge end. Accordingly, the novelty is characterized in that it comprises at least one safety element, at least one lens arm which can be inserted between the optical and haptic parts of the lens on the safety element to prevent contact of the lens with the cartridge prior to bending, and a safety tab to be inserted into at least one button recess on the button to limit the movement of the button towards the cartridge before use. Therefore, a cartridge injector system is achieved, which reduces lens folding problems and can be safely transported.

[0014] A possible embodiment of the invention is characterized in that it comprises at least one retaining protrusion for arranging the lens arm between the optical and haptic parts of the lens. The lens can thus be held and arranged safely between the optic and haptic parts thanks to the retaining protrusion on the arm.

[0015] Another possible embodiment of the invention is characterized in that it comprises at least one support protrusion for limiting the movement of the folding part of the lens arm. Thus, the folding part moves within the desired limits thanks to the support protrusion and helps to fold the lens as desired.

[0016] Another possible embodiment of the invention is characterized in that the lens arm is located on the opposite sides of the safety element. The safety element thus holds the lens arm on both sides, ensuring that the lens is securely arranged.

[0017] Another possible embodiment of the invention is characterized in that it comprises two opposite safety tabs on the safety element and at least two button recesses on the button to be associated with said safety tabs. Thus, the safety element moves towards the safety tabs on the button, preventing the lens from contacting the cartridge and preventing the undesired pressures.

[0018] Another possible embodiment of the invention is characterized in that it comprises at least one arm recess on the button for passing the lens arms therethrough. The lens arms can then be inserted safely through the arm recesses on the button and used effectively on the cartridge injector system.

[0019] Another possible embodiment of the invention is characterized in that the safety tabs are at least partially flexible. The safety tabs thus ensure safety and prevent the undesired situations by preventing the lens from contacting the cartridge when not in use. BRIEF DESCRIPTION OF THE DRAWING

[0023] DETAILED DESCRIPTION OF THE INVENTION

[0024] In this detailed description, the subject of the invention is only described with the examples without any limiting effect for a better understanding of the subject.

[0025] Fig. 1 shows a representative perspective view of the cartridge injector system (1 ) of the invention. Accordingly, the cartridge injector system (1 ) of the invention is configured to allow at least partial folding of the lens (I) in the intraocular implantation procedures. The cartridge injector system (1 ) is used to replace the natural lens (I) with an artificial lens (I) in cases where the lens of the eye is deformed, such as cataract. There are various components on the cartridge injector system (1 ) to perform these procedures and they work in synchronization with each other.

[0026] Fig. 2 shows a representative exploded view of the cartridge injector system (1 ) of the invention. Accordingly, the cartridge injector system (1 ) comprises at least one body (10) and at least one cartridge (20) on said body (10). Said cartridge (20) allows the lens (I) placed thereon to be held and folded. For this purpose, at least one folding part (21 ) is provided on the cartridge (20). Said folding part (21 ) allows at least partial folding of the lens (I). For this purpose, in a possible embodiment of the invention, the folding part (21 ) is configured to be at least partially rounded by the operator. In this way, the lens (I) placed on the folding part (21 ) is also folded.

[0027] There is at least one button (30) on the cartridge injector system (1 ) for bending the cartridge (20). Said button (30) is moved towards the cartridge (20), rounding the folding part (21 ) and bending the lens (I). To do this, the button (30) may be provided with a structure shaped to allow bending of the folding part (21 ) of the cartridge (20) in the inner part. The fluid can be introduced into the cartridge (20) for folding the lens (I). This facilitates the shaping of the lens (I) in the cartridge (20) and its discharge from the cartridge (20). The fluid used to do this can be substantially saline or a viscoelastic fluid. These fluids are distilled water solutions containing certain amounts of sodium bicarbonate and sodium chloride. They provides the lubrication of the lens (I) in the cartridge (20). At least one discharge end (22) is located adjacent to the cartridge (20). The discharge end (22) is the movement path that allows the lens (I) folded in the folding part (21 ) to be discharged out of the cartridge injector system (1 ).

[0028] There is at least one body (10) on the cartridge injector system (1 ). Said body (10) is the main structure on which the elements of the cartridge injector system (1 ) are arranged in a balanced manner. For this purpose, the body (10) has a hollow cylindrical structure. Said button (30) is arranged on the body (10). At least one button tab (31 ) on the button (30) is arranged in at least one body recess (1 1 ) on the body (10), allowing the two parts to be connected to each other. At least one piston (40) is arranged in the cartridge injector system (1 ). Said piston (40) ensures that the lens (I) in the cartridge (20) is discharged from the discharge end (22). To do this, the piston (40) can move at least partially in the direction of extension of the body (10).

[0029] Fig. 3 shows a representative perspective view of the safety element (50) in the cartridge injector system (1 ) of the invention. Accordingly, when the cartridge injector system (1 ) is not in use, it is undesirable to move the button (30) towards the cartridge (20) and bring the lens (I) into contact with the cartridge (20). For this purpose, the cartridge injector system (1 ) comprises at least one safety element (50). The safety element (50) prevents the lens (I) from contacting the cartridge (20) when not in use and prevents the button (30) from being pressed. For this purpose, the safety element (50) comprises at least one lens arm (51 ) for holding the lens (I). Said lens arm (51 ) is the part of the safety element (50) that extends towards the cartridge (20). There are preferably two opposite lens arm (51 ) on the safety element (50) and serves to hold the lens (I) between the optical and haptic parts. The lens arm (51 ) is provided with at least one retaining protrusion (52) to be inserted between the optical and haptic parts. In addition, at least one support protrusion (53) is provided on the outwardly facing sides of the lens arm (51 ). Said support protrusion (53) rests against the folding part (21 ) of the cartridge (20), preventing the cartridge (20) from folding the lens (I). The support protrusion (53) is arranged on opposite sides of the lens arms (51 ). This prevents the cartridge (20) from being folded on both opposite sides.

[0030] The safety element (50) is configured to prevent the button (30) from being pressed towards the cartridge (20). For this purpose, there is at least one safety tab (54) on the safety element (50). Said safety tab (54) is configured to be inserted in at least one button recess (32) on the button (30). In the preferred embodiment of the invention, there are two safety tabs (54) on the safety element (50) and two button recesses (32) on the button (30) to be aligned with these safety tabs (54). Thus, the safety element (50) is arranged on the button (30) and the movement of the button (30) is prevented. The button (30) is also provided with at least one arm recess (33) to allow the passage of the lens arms (51 ).

[0031] In a possible usage scenario of the invention, the safety element (50) is arranged on the button (30) and the lens (I) is inserted between the lens arms (51 ). The button (30) is then connected to the body (10). In this state, the movement of the button (30) relative to the cartridge (20) and contact of the lens (I) with the cartridge (20) is prevented. When it is desired to use the cartridge injector system (1 ), the safety tabs (54) on the safety element (50) are flexed by pushing towards each other and separated from the button recesses (32) and moved away from the button (30). Subsequently, the lens (I) fluid is introduced into the cartridge (20) and the lens (I) is bent by means of the button (30) and the discharge from the body (10) is completed by means of the piston (40).

[0032] Some of the benefits provided by this structure of the cartridge injector system (1 ) are as follows:

[0033] Ease of Intraocular Lens (I) Implantation: The cartridge injector system (1 ) can facilitate the surgical procedures by allowing the lens (I) to be folded in the intraocular implantation procedures. This can be particularly useful when replacing the natural lens (I) with an artificial lens (I), for example in cases such as cataract.

[0034] Foldable Lens (I) Design: The cartridge injector system (1 ) comprises a folding part (21 ) which allows the lens (I) to be at least partially folded. This allows easier handling and implantation of the lens (I) inserted in the cartridge (20). Operator-Controlled Folding: The folding part (21 ) can be at least partially rounded by the operator, providing flexibility to enable folding of the lens (I).

[0035] Button (30) Mechanism for Bending Procedure: The button (30) on the cartridge injector system (1 ) is used to bend the lens (I) in the cartridge (20). This allows the lens (I) to take the desired shape.

[0036] Use of Fluid for Lubrication of Lens (I): The fluid introduced into the cartridge (20) allows the lens (I) to be shaped more easily in the cartridge (20). The solutions such as saline or viscoelastic fluid can help lubricate the lens (I).

[0037] Accident Prevention with Safety Element (50): The cartridge injector system (1 ) comprises a safety element (50) to prevent contact of the lens (I) with the cartridge (20) when not in use. This can prevent the undesired situations and accidents.

[0038] Body (10) Design: The cartridge injector system (1 ) has a balanced structure on the body (10), which can improve the durability and functionality of the system.

[0039] Operation Control with Safety Tabs (54): The safety tabs (54) on the safety element (50) prevent the button (30) from pressing the cartridge (20) when not in use, thus preventing the undesired movement. These advantages allow the cartridge injector system (1 ) to be used in the intraocular lens (I) implantation procedures in a safer, controlled and effective manner.

[0040] The scope of protection of the invention is described in the attached claims and cannot be limited to what is explained in this detailed description for the exemplary purposes. It is clear that a person skilled in the art can produce similar embodiments in the light of what is explained above, without deviating from the main theme of the invention.
