AI Technical Summary

⚠Technical Problem

Existing implant delivery systems for eye surgery, such as intraocular lenses, lack efficient mechanisms for precise assembly and deployment, often requiring multiple steps and lacking tactile and audible feedback for proper alignment.

⚗Method used

A system comprising a dial mechanism with folding arms and edge rollers that provide tactile and audible feedback, allowing for a single-turn assembly of intraocular lenses, featuring slots, tracks, and pins to fold haptics over the optic body, with ratchet teeth ensuring secure engagement and rotation.

🎯Benefits of technology

Enables precise, single-turn assembly of intraocular lenses with tactile and audible feedback, enhancing surgical efficiency and reducing the risk of misalignment during implant deployment.

Abstract

An apparatus for eye surgery may include an implant support, a folding arm (330), an edge roller (335), and a dial (320). Some embodiments of the implant support may include an implant bay, a tab rail, a tab slot, and a pawl. The folding arm may be coupled to the implant support and may include a dial pin. The edge roller may be coupled to the implant support and may include a roller track. Some embodiments of the dial may include an arm track, a roller pin, a plurality of ratchet teeth, and a tab. The dial can be configured to be rotated relative to the implant support so that the ratchet teeth rotate relative to the pawl, the dial pin travels the arm track and causes the folding arm to rotate, and the roller pin then travels the roller track to cause the edge roller to rotate.
