Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical illumination systems face challenges in providing adequate visibility during endoscopic procedures due to varying anatomical profiles, leading to prolonged procedures and potential patient injury from lack of visibility.
Innovation Solution
A medical system with a computing device that automatically adjusts illumination from multiple light sources based on real-time image data to optimize lighting conditions within the target anatomy, using a first light for broad beam and a second light for narrow beam profiles to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source is used for illumination, then the device complexity is reduced, but the illumination intensity and visibility in different anatomical regions are insufficient
Solution Approach 1:
The illumination system is divided into multiple independent light sources (first light and second light) positioned at different locations on the endoscope. Each light source can be independently controlled to illuminate specific anatomical regions, thereby increasing overall illumination intensity without requiring a single complex high-power source.
Solution Approach 2:
Different light sources are directed to provide non-uniform illumination tailored to different anatomical regions. The system adjusts illumination characteristics locally based on the specific requirements of each region being observed, improving visibility where needed while maintaining manageable device complexity.
2Adaptability or versatility
If fixed illumination parameters are used, then the ease of operation is improved, but the adaptability to varying anatomical profiles is reduced
Solution Approach 1:
The illumination parameters are made dynamic and adjustable rather than fixed. The system can modify light intensity, distribution, and characteristics in real-time to adapt to varying anatomical profiles during the procedure, while the automated control maintains ease of operation.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the illumination effectiveness and anatomical conditions, automatically adjusting the illumination parameters to maintain optimal visibility across different anatomical profiles without requiring manual intervention.
3Productivity
If manual adjustment of illumination is performed, then the device complexity is reduced, but the loss of time during procedure adjustment increases
Solution Approach 1:
The illumination system performs self-adjustment through automated control algorithms that monitor anatomical conditions and independently modify illumination parameters. This eliminates the need for manual adjustment by the operator, reducing procedure time while the automation handles the complexity of real-time optimization.
4Reliability
If insufficient illumination is provided, then the energy consumption is reduced, but the harmful factors such as procedure prolongation and patient injury risk increase
Solution Approach 1:
The system applies illumination selectively to specific regions that require enhanced visibility, rather than uniformly illuminating all areas. This partial action approach provides sufficient light where needed for safety while avoiding excessive energy consumption in regions where standard illumination is adequate.

AI summary
A medical system that includes a shaft having a distal end configured to be positioned at a target site, a first light and a second light positioned at the distal end, and a computing device communicatively coupled to the first and second light. The computing device includes a processor and non-transitory computer readable medium storing instructions that, when executed by the processor, causes the processor to determine a first illumination measurement of a first region of the target site by the first light and a second illumination measurement of a second region of the target site by the second light. The second region is different than the first region. The processor adjusts emittance from the first light, in response to the first illumination measurement being different than a first threshold, and emittance from the second light in response to the second illumination measurement being different than a second threshold.
