AI Technical Summary

Technical Problem

Traditional clamping methods, such as mechanical grippers, directly contact the edge or haptic region of the intraocular lens, leading to localized stress concentration. This can cause scratches, deformation, or breakage, especially for intraocular lenses made of hydrophilic or softer materials, where the risk is even higher.

Method used

It employs the synergistic effect of primary and secondary adsorption components, and achieves multi-part vacuum adsorption through negative pressure generation components to avoid mechanical contact. The combination design of soft rubber rings and ceramic discs buffers the adsorption force, and pistons and elastic components control changes in negative pressure to automatically switch adsorption positions.

Benefits of technology

It achieves stable clamping without stress damage, simplifies the operation process, avoids scratches and deformation of the artificial lens, and improves processing quality and production efficiency.
