Description
Technical Field
[0001] This utility model relates to the field of intraocular lens technology, and in particular to an electrically powered intraocular lens implantation system. Background Technology
[0002] Currently, intraocular lens (IOL) implantation is typically performed manually, requiring a doctor's intervention throughout the process. However, each doctor's implantation method and technique vary, potentially leading to the IOL ejecting into the capsular capsule and causing injury. Furthermore, the injection speed affects IOL deformation; rapid injection can cause scratches and tears. In addition, the complex procedure requires extensive specialized training for doctors to successfully implant the IOL, increasing their workload. Therefore, there is an urgent need to develop a motorized IOL implantation system to address these technical challenges.
[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

The injection speed is uniform, stable, and controllable during the injection process, and the deformation of the intraocular lens is controllable, thereby reducing scratches and tears, lowering the risks during the implantation process, and improving the success rate of implantation. In addition, it can reduce the amount of training required for doctors and reduce their workload. It has broad application prospects and is conducive to its widespread application.
