Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic surgical systems require complex and time-consuming setup processes for vitreoretinal surgeries, involving multiple fluidic connections and manual identification of surgical cassettes, which can lead to inefficiencies and increased risk of errors.
Innovation Solution
An ophthalmic surgical system featuring a fluidics module with a surgical cassette bay and indicator lights corresponding to fluidic ports, controlled by a processor that determines the type of surgical cassette and illuminates the appropriate indicator lights, facilitating efficient setup and reducing manual errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual identification and setup of surgical cassettes is used, then device complexity is reduced, but setup time and risk of errors increase
Solution Approach 1:
The surgical cassette contains an integrated identifier (such as a barcode, RFID tag, or optical code) that automatically identifies itself when placed in the surgical cassette bay. The system autonomously reads the identifier and configures the fluidic connections without requiring manual intervention or external programming, enabling self-service setup.
Solution Approach 2:
The patent replaces manual mechanical identification and configuration processes with automated optical, electromagnetic, or RFID-based identification systems. The identifier on the cassette is read by an optical sensor or RFID reader, substituting the mechanical/manual process of visually identifying and manually configuring connections.
2Measurement precision
If manual configuration of fluidic connections is used, then ease of operation is maintained, but measurement precision and accuracy of connections decrease
Solution Approach 1:
The system provides visual feedback through indicator lights that illuminate to confirm correct fluidic connections. Each fluidic port has a corresponding indicator light that shows whether a tube is properly connected, providing immediate feedback to the operator to verify connection accuracy.
Solution Approach 2:
The system automatically determines the surgical cassette type and configures the appropriate fluidic connections without requiring manual setup. The processor reads the identifier, determines the cassette type, and automatically routes fluidic connections, eliminating the need for manual configuration while ensuring accuracy.
3Productivity
If automated identification system is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The identification system is segmented into modular components: an identifier element on the surgical cassette (such as a barcode or RFID tag) and a corresponding reader in the surgical cassette bay. This segmentation allows the automated identification function to be added as a discrete module rather than requiring complete system redesign.
Solution Approach 2:
The identifier on the surgical cassette serves multiple functions: it identifies the cassette type, determines the required fluidic connections, and enables automated setup. This multi-functionality consolidates what would otherwise require separate systems into a single integrated solution.

Data Source
AI summary
Certain embodiments disclosed herein provide an ophthalmic surgical system. The system includes a fluidics module and a controller. The fluidic module includes a surgical cassette bay and one or more indicator lights. The one or more indicator lights correspond to one or more fluidic ports on the fluidics module. The controller includes a memory including executable instructions and a processor. The processor is in data communication with the memory. The processor is configured to execute the instructions to cause the system to: determine that a surgical cassette is coupled to the surgical cassette bay; determine a type of the surgical cassette; illuminate at least one of the one or more indicator lights based on the determined type of the surgical cassette; and extinguish the at least one of the one or more indicator lights upon receiving an input indicating that a fluidic tubing is fluidically coupled with the corresponding fluidic port.
