Translucent Housing Light Instrument for Peripheral Retinal Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmological illumination systems are inadequate for visualizing peripheral retinal regions due to limited aperture angles in surgical microscopes, requiring additional instruments and assistants, which increase costs and risk of eye injury.
Innovation Solution
A device combining a translucent material housing with a light instrument that serves as both an illuminator and sclera depressor, providing uniform light distribution and allowing for indentation of eye tissue without additional illumination tools, thus enabling visualization of peripheral regions without additional access ports or assistants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light instrument is fixed in the eye for illumination, then good illumination is achieved, but additional injury to the patient's eye occurs due to the fourth access into the eye
Solution Approach 1:
The patent combines the illumination function and sclera depressor function into a single integrated device. The light instrument is merged with the sclera depressor structure, allowing illumination to be provided through the same access point used for scleral depression, thereby eliminating the need for a separate fourth access port and reducing additional eye injury risk
2Ease of operation
If additional instruments and assistants are used for peripheral region operation, then adequate illumination and depression functions are achieved, but costs and device complexity increase
Solution Approach 1:
The patent creates a universal device that performs multiple functions: illumination, sclera depression, and peripheral retinal visualization. The integrated device eliminates the need for separate illumination instruments and assistant physicians, reducing device complexity while maintaining full operational capability for peripheral region surgery
3Illumination intensity
If a translucent material is used in the housing, then uniform light distribution is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes the optical parameters of translucent materials (light scattering and transmission properties) to achieve uniform light distribution. By selecting appropriate translucent materials and designing the housing geometry to optimize light path, the patent achieves uniform illumination without requiring complex optical components or manufacturing processes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures safe, simple handling with effective illumination and indentation, reducing costs and minimizing eye injury by integrating illumination and indentation functions into a single instrument, allowing for precise surgical interventions in peripheral regions.
Implementation Method 1
This is attributable to the intrinsic properties of translucent material, which brings about a high degree of scattering and reflection of impinging light
Implementation Method 2
Light reflections that disturb the user during use are avoided as a result
