[0002] Intraocular lens implantation is a surgical method for treating cataracts. It is currently the most effective method for correcting aphakic refraction, and can also be used for corrective treatment for myopic patients. There are no adverse reactions when intraocular lens is implanted in the eye, it is extremely safe, and can completely preserve the corneal tissue. An intraocular lens injector is generally required when implanting an intraocular lens.

[0003] According to the Chinese patent with the authorized publication number CN220124949U, an intraocular lens injector is disclosed. The injector has a simple structure, and the three-piece intraocular lens is positioned so that it can be pushed forward smoothly, avoiding the situation where the lens is squeezed into a ball due to disordered placement during injection and cannot be relaxed and opened when entering the eye, thereby improving the reliability of the implantation operation.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a zero-friction foldable intraocular lens injector, including a first syringe barrel 1, the left side of the first syringe barrel 1 is hinged to a second syringe barrel 2 through a hinge, a folding clip 3 is fixed to the left side of the second syringe barrel 2, a folding assembly 400 for realizing folding is arranged inside the first syringe barrel 1, a syringe needle 5 is fixed to the left side of the folding clip 3, a push rod 7 is slidably connected inside the first syringe barrel 1, and a sliding assembly 900 for making the sliding more convenient is arranged inside the first syringe barrel 1.

[0025] Through the combined use of the first syringe barrel 1, the second syringe barrel 2, the folding clip 3, the folding assembly 400, the push rod 7 and the sliding assembly 900, in the actual use process, when the intraocular lens injector is used up, the intraocular lens injector can be effectively folded, so that it is more convenient for the subsequent medical staff to store and place the intraocular lens injector. Moreover, it can effectively reduce the friction during the injection of the intraocular lens injector, so that the medical staff has a better experience when using it, and the practicability of the zero-friction foldable intraocular lens injector is improved.

[0026] In this embodiment, the folding assembly 400 is a structure for folding the intraocular lens injector.

[0027] Such as Figure 1 , Figure 2 And Figure 3As shown in the figure, the folding assembly 400 includes a moving plate 401 slidably connected inside the first syringe barrel 1. A limiting rod 402 is slidably connected inside the moving plate 401. A moving groove 403 is formed at the top of the first syringe barrel 1. A fixing column 404 is fixed to the left side of the moving plate 401. A spring 405 is fixed to the left side of the moving plate 401. An installation groove 406 is formed inside the first syringe barrel 1. A plug-in groove 407 is formed on the right side of the second syringe barrel 2.

[0028] It should be noted that a handheld piece 6 is fixed to the right side of the first syringe barrel 1 to ensure that the staff can conveniently hold the intraocular lens injector through the handheld piece 6. A silicone head 8 is fixed to the left end of the push rod 7. Using silicone material can effectively avoid damaging the lens during the pushing process and facilitate subsequent cleaning and disinfection.

[0029] In addition, an intraocular lens placement cavity 31 is provided inside the folding clip 3 for placing the lens. An anti-clamping groove 32 is formed inside the folding clip 3, which can effectively prevent the folding clip 3 from clamping the lens when it closes, thus affecting the smoothness of the subsequent injection process. The left end of the fixing column 404 sequentially passes through the installation groove 406, the first syringe barrel 1 and the second syringe barrel 2 and is inserted into the plug-in groove 407 to ensure that the fixing column 404 can be effectively inserted into the plug-in groove 407, thereby realizing the fixation of the first syringe barrel 1 and the second syringe barrel 2.

[0030] Among them, the width of the moving plate 401 is equal to the width of the moving groove 403, making the movement of the moving plate 401 in the moving groove 403 more stable. The spring 405 is located outside the fixing column 404. The installation groove 406 is communicated with the moving groove 403. The spring 405 away from the moving plate 401 is sequentially fixed inside the installation groove 406 to ensure that the spring 405 can play the expected elastic effect.

[0031] In addition, the sliding assembly 900 includes a piston member 901 fixed to the outside of the push rod 7. Fixing grooves 902 are formed at the top and bottom of the piston member 901. An installation rod 903 is fixed inside the fixing groove 902. A roller 904 is rotatably connected to the outside of the installation rod 903. Sliding grooves 905 are formed on the inner top wall and inner bottom wall of the first syringe barrel 1.

[0032] At the same time, the roller 904 is slidably connected inside the sliding groove 905. The adjustable distance of the roller 904 in the sliding groove 905 is greater than the adjustable distance of the push rod 7 in the folding clip 3, effectively preventing the roller 904 and the sliding groove 905 from affecting the normal pushing of the push rod 7.

[0033] The working principle of the above embodiment is as follows:

[0034] During use, first place the lens to be used into the folding clip 3, and then through the cooperation of the push rod 7, the silicone head 8 and the intraocular lens placement cavity 31, the lens is pushed out from the injection syringe 5 to achieve injection. After use, pull the moving plate 401 to the right, thereby driving the fixed column 404 to move to the right, and under the action of the limiting rod 402, the moving plate 401 moves more stably in the moving groove 403, so that the fixed column 404 is separated from the insertion slot 407. At this time, the spring 405 is in a stretched state, thereby releasing the limit of the fixed column 404 on the second injection cylinder 2, and the intraocular lens injector can be folded through the first injection cylinder 1 and the second injection cylinder 2. When it needs to be used later, after disinfecting structures such as the silicone head 8, under the elastic action of the spring 405, the fixed column 404 is inserted into the insertion slot 407 again, and the first injection cylinder 1 and the second injection cylinder 2 can be fixed again, thus completing the assembly of the intraocular lens injector. The operation is relatively simple. And during the process of pushing the push rod 7, through the cooperation of the roller 904, the mounting rod 903 and the sliding groove 905, the friction when pushing the push rod 7 can be effectively reduced, making it more convenient for medical staff to use.

[0035] Compared with the prior art, for this zero-friction foldable intraocular lens injector, through the cooperation of the first injection cylinder 1, the second injection cylinder 2, the folding clip 3, the folding assembly 400, the push rod 7 and the sliding assembly 900, during the actual use process, when the intraocular lens injector is used up, it can effectively fold the intraocular lens injector, making it more convenient for medical staff to store the intraocular lens injector later. And it can also effectively reduce the friction during the injection of the intraocular lens injector, making the experience of medical staff better when using it, improving the practicability of the zero-friction foldable intraocular lens injector, and solving the problem of the low practicability of the existing intraocular lens injectors.
