Modular Laser Therapeutic Device for Ophthalmic Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic laser devices are limited to separate modules for treatments like Selective Laser Trabeculoplasty (SLT), Photodisruptor (PD), and Photocoagulator (PC), lacking a single, integrated device capable of performing all three therapies.
Innovation Solution
A modular laser therapeutic device integrating three therapeutic modules - PD, SLT, and PC - using two laser sources, one emitting 1064 nm pulses for PD and vitreolysis, frequency-doubled to 532 nm for SLT, and a continuous wave at 532 nm for PC, with optomechanical switching between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate laser devices are used for SLT, PD, and PC treatments, then each device can be optimized for its specific function, but the overall device complexity increases and treatment efficiency decreases
Solution Approach 1:
The patent combines three separate laser therapeutic devices (SLT, PD, and PC) into a single integrated device. The laser source, optical components, and control systems are merged while maintaining distinct functional modules for each treatment type, allowing one device to perform multiple ophthalmic procedures that previously required three separate devices
Solution Approach 2:
The integrated device is designed with universal functionality to perform Selective Laser Trabeculoplasty (SLT), Photodisruptor (PD), and Photocoagulator (PC) treatments. The system uses a single laser source that can be configured for different wavelengths and pulse durations, with interchangeable optical components and adjustable parameters to accommodate all three treatment modalities
2Productivity
If multiple separate devices are used for different eye treatments, then each device can be optimized for its specific treatment, but treatment time and operational efficiency increase
Solution Approach 1:
By merging SLT, PD, and PC functionalities into one device, the patent eliminates the need to transport and set up multiple separate devices. The integrated system allows ophthalmologists to perform different treatments sequentially or in combination within a single patient visit, reducing overall treatment time and improving clinical workflow efficiency
3Ease of operation
If a single integrated device is used for all treatments, then device complexity decreases and treatment efficiency improves, but the ability to optimize each treatment modality independently is reduced
Solution Approach 1:
The integrated device is segmented into distinct functional modules for SLT, PD, and PC treatments. Each module maintains its own optimized optical path, beam shaping components, and control parameters. This modular segmentation within the integrated system allows each treatment modality to be independently optimized while benefiting from the convenience of a single device platform
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
Enables comprehensive eye surgery treatments for cataracts, glaucoma, and retinal diseases in a single device, enhancing treatment flexibility and efficiency.
Implementation Method 1
one emitting 1064 nm pulses for PD and vitreolysis, frequency-doubled to 532 nm for SLT
Implementation Method 2
with the excitation pulse focused just behind the intraocular lens and posterior capsule, typically to 100-200 micrometers
Implementation Method 3
This high-intensity laser pulse induces an optical breakdown resulting in a micro explosion initiated by plasma formation
Implementation Method 4
These specific treatment settings limit the heat-related damage and preserve the trabecular meshwork. Such laser pulses induce selective photothermolysis of the intracellular melanin granules in the trabecular meshwork cells
Implementation Method 5
a continuous wave at 532 nm for PC
