Stroboscopic Ophthalmic Illuminator for Vibrating Surgical Tool Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rapid oscillation of mechanical cutting tools during ophthalmic surgical procedures causes blurring of the operating field, obscuring both the tool and surrounding ocular tissues, making it difficult for surgeons to visualize the surgical area effectively.
Innovation Solution
A stroboscopic ophthalmic illuminator system that includes a pulse generator, amplifier, and light source, synchronized to the vibration frequency of the surgical tool, producing short light pulses to create a stroboscopic effect that allows clear visualization of the tool's movement and surrounding tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical cutting tools oscillate at high frequency during ophthalmic surgical procedures, then cutting efficiency is improved, but the operating field becomes blurred and obscured
Solution Approach 1:
The patent applies periodic action by synchronizing the light source illumination to the vibration frequency of the surgical tool. The light source is activated in periodic pulses that match the tool's oscillation cycle, creating a stroboscopic effect where the rapidly vibrating tool appears stationary or slowly moving, thereby maintaining visibility during high-frequency cutting operations
Solution Approach 2:
The patent changes the temporal parameter of illumination by transitioning from continuous lighting to pulsed illumination synchronized with the tool's vibration frequency. This parameter change in the illumination timing transforms the visual perception of the vibrating tool, allowing surgeons to clearly see the tool head and surrounding tissues despite rapid oscillation
2Difficulty of detecting and measuring
If continuous light illumination is used during surgical procedures, then the operating field is always visible, but the rapid oscillation of cutting tools causes motion blur that obscures detail
Solution Approach 1:
The patent uses periodic action by synchronizing illumination pulses with the tool's vibration frequency. This creates a stroboscopic effect where the tool appears frozen in position during each pulse, eliminating motion blur and providing sharp visual clarity of both the tool head and surrounding ocular tissues
Solution Approach 2:
The patent creates a visual copy or image of the tool and tissues at specific moments in the vibration cycle. By capturing the scene during the tool's transient stationary phases (synchronized with light pulses), the system creates clear visual copies of the tool head and tissues without the distortion of motion blur

Data Source
AI summary
An ophthalmic illuminator is provided that includes a pulse generator to provide amplified pulses and an amplifier to amplify the current pulses to produce amplified pulses. A light source within the ophthalmic illuminator is driven by the amplified pulses so as to stroboscopically illuminate a vibrating ophthalmic surgical tool within the interior of an eye.
