Intraocular Lens Injection System with Restriction Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intraocular lens (IOL) injection systems face challenges in safely storing IOLs without applying stress, which can lead to breakage, and require complex processes for releasing the IOL from storage, consuming doctor time and potentially compromising sterilization.
Innovation Solution
An IOL injection system comprising an injector with a lens storage part and a holder that uses restriction members to securely hold the IOL during storage, preventing movement and stress, and a simple release mechanism to easily transition the IOL to a usable position, featuring a plunger and release part to fold and inject the lens without external force errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the IOL is stored in a preset-type injector during conveyance, then the IOL can be readily available for injection, but impact during conveyance causes breakage of the stored IOL
Solution Approach 1:
The holder is divided into multiple cell bodies (first cell body and second cell body) that can be independently opened. Each cell body contains a separate injector, allowing selective access to individual IOLs without disturbing others, thus maintaining integrity while enabling readiness.
Solution Approach 2:
The injectors are pre-loaded with IOLs in a sterilized state and stored in the holder in advance. The holder maintains this preliminary prepared state during conveyance, and the IOLs remain protected until the moment of use when the specific cell body is opened.
2Reliability
If the IOL is released from storage state with complex processes, then the IOL can be safely removed, but it consumes doctor time and effort and may compromise sterilization
Solution Approach 1:
The injector is extracted as a complete unit from the holder's cell body, already containing the sterilized IOL. This extraction provides a sterile barrier that maintains sterilization status while enabling quick removal of the injector for use, eliminating complex removal processes.
Solution Approach 2:
The holder acts as an intermediary container that maintains the sterilized storage state during conveyance. The cell body structure serves as a sterile barrier that protects the IOL until use, at which point the entire injector (with its own sterile field) is removed as a unit.
