Ophthalmic Cassette Refraction Element Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic surgical cassettes lack an effective identification feature to accurately indicate the cassette type to the surgical console, leading to potential errors in enabling or disabling surgical functions, especially when generic containers are used with different manifold bases, which can result in incorrect procedure execution.
Innovation Solution
Incorporating a refraction element as an identification feature on the manifold base of the ophthalmic surgical cassette, which uses light refraction to uniquely indicate the cassette type to the console, enabling precise detection and disabling of appropriate surgical functions, thereby ensuring the correct procedure is performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If generic containers are used with different manifold bases, then device versatility and ease of manufacture are improved, but measurement precision and reliability of cassette type identification deteriorate
Solution Approach 1:
The patent applies local quality by placing a specific refraction element only at the distal end of the manifold base, creating a localized identification feature. This allows the manifold base to maintain its generic compatibility while the localized refraction element provides precise cassette type identification through unique light refraction patterns detected by the console.
Solution Approach 2:
The refraction element acts as an intermediary between the physical cassette and the console's detection system. It converts physical cassette type differences into optical signals (light refraction patterns) that the console can accurately detect and interpret, thereby enabling precise identification without requiring direct mechanical or electronic interfaces.
2Measurement precision
If refraction element is added to manifold base, then measurement precision and reliability of cassette type detection are improved, but device complexity increases
Solution Approach 1:
The refraction element is integrated into the disposable manifold base rather than being a separate permanent component. This allows the identification feature to be manufactured as part of the single-use cassette assembly, reducing the need for complex reusable identification mechanisms and keeping the overall system relatively simple despite the added detection capability.
Solution Approach 2:
The patent replaces potential mechanical identification systems (such as physical keys, slots, or mechanical interfaces) with an optical refraction element. This substitution simplifies the mechanical structure while enabling more precise and reliable cassette type detection through optical means.

Function Achieved in This Case

AI summary
An ophthalmic surgical cassette for use with an ophthalmic surgical console. The ophthalmic surgical cassette includes a rigid-walled container having an interior volume for collecting aspirant fluid and/or tissue, and a manifold base, including an irrigation tube for coupling an irrigation source, an aspiration tube for coupling an ophthalmic surgical handpiece, and an identification feature for indicating a cassette type to an ophthalmic surgical console. The manifold base is removeably attached to the rigid-walled container.
