Description

Technical Field

[0001] This invention relates to the field of intraocular lens technology, and more particularly to a trigger-type intraocular lens injector. Background Technology

[0002] Intraocular lenses (IOLs) are currently the most effective method for correcting refractive errors in aphakic eyes. Existing techniques typically involve using forceps to place the IOL into an IOL implantation device, folding the IOL using a folding mechanism, and then implanting it into the eye through the device. This process is complex, requires trained nurses, and is highly specialized, making it prone to problems. Furthermore, using forceps to hold the IOL can damage it, increasing the risk of contamination, infection, and slower recovery. Additionally, push-type IOL injectors often have uneven injection speeds, which can also cause injury, and the relatively large injection force required affects the effectiveness. While rotary injectors address the issue of high injection force, they require two hands, are complex to operate, and result in slow injection. Therefore, there is an urgent need to develop a trigger-type IOL injector to solve these technical problems.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

In the initial state, the crystal tablet handle 9 is always stopped at this position to prevent accidental activation and damage to the intraocular lens 8 during transportation. The forward stop groove engages with the forward stop post 403 of the crystal tablet latch 4. With the cooperation of column 402, the crystal pressure tablet 7 is pushed to this position and locked, unable to move forward. Without the application of external force, the crystal pressure tablet handle 9 will not retract, thus preventing the crystal pressure tablet handle 9 from retracting and affecting the surgical effect. The crystal pressure tablet handle 9 is provided with a connecting column 904, which cooperates with the crystal pressure tablet handle connecting slot 702. The crystal pressure tablet handle 9 can rotate freely, preventing damage to the crystal pressure tablet handle 9 during transportation. The crystal pressure tablet handle 9 passes through the crystal pressure tablet handle insertion slot 401, making assembly convenient and operation simple.

[0029] The assembly process of this invention is as follows: (1) Connect the injection rod 5 and the injection needle 6 with a snap-fit ​​connection, which cannot be rotated, and insert the above components into the main body 2; (2) The long slot 103 of the trigger 1 is engaged with the trigger movement shaft 506 of the injection rod 5, and the main body connecting shaft hole 102 of the trigger 1 is engaged with the trigger rotation shaft 207 of the main body 2.

[0030] The working principle of this invention is as follows: Viscoelastic agent is injected into the inlet head 3 through the injection port of the inlet head. The crystal tablet handle 9 is pushed to pre-compress the artificial lens 8, causing the artificial lens 8 to fold in the designed direction. Then, the trigger 1 is pulled to move the injection needle 6 forward. When the injection needle 6 is not in contact with the artificial lens 8, it is an empty injection. If the trigger 1 is pulled again, the injection needle 6 continues to move forward. When the injection needle 6 contacts the artificial lens 8, the injection of the artificial lens 8 begins. The artificial lens 8 passes through the inlet head 3, and the injection is completed.

[0031] This invention features a simple structure, ingenious design, and convenient processing, assembly, and operation. It not only saves injection force but also ensures a more uniform injection speed, preventing damage to the intraocular lens 8. Injection can be performed with one hand, while the other hand can hold the front end of the main body 2, making operation more stable. The trigger-type design is more ergonomic and comfortable to use. Furthermore, the intraocular lens 8 is pre-assembled in a sterile factory workshop, reducing the risk of contamination. It has broad application prospects and is conducive to widespread application.
