Rotating Reflecting Surface for Endoscopic Light Irradiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light therapy inside the body under endoscopic observation faces challenges in accurately capturing and irradiating treatment sites, particularly those not visible from the front, such as tumors on inner walls of gastrointestinal tracts, due to blurring effects and the need to irradiate both front and lateral sides without changing the endoscope.
Innovation Solution
A therapeutic light irradiation device with a reflecting surface on the endoscope's insertion section that can switch the irradiation direction of therapeutic light between a first direction and a second direction intersecting the first, allowing for both front and lateral side irradiation without changing the endoscope position, and a connector for detachable attachment to the insertion section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the endoscope is used to observe treatment sites, then the treatment sites can be visualized, but blurring effects from patient pulsations make it difficult to capture treatment sites at positions where therapeutic light can be readily radiated
Solution Approach 1:
A reflecting surface is introduced as an intermediary component between the light source and the treatment site. This reflecting surface can be rotated to redirect therapeutic light at different angles, allowing irradiation of treatment sites that are difficult to reach with direct front-side illumination, thereby improving irradiation reliability without compromising visualization accuracy
2Adaptability or versatility
If the endoscope position is changed to irradiate lateral side tumors, then treatment sites on inner walls can be treated, but it requires changing the endoscope position which complicates the procedure
Solution Approach 1:
The reflecting surface is designed to be rotatable, allowing dynamic adjustment of the therapeutic light irradiation direction. This enables the system to adapt to different treatment site locations (front side or lateral side) without requiring physical repositioning of the endoscope, thereby improving irradiation coverage while maintaining operational simplicity
Solution Approach 2:
The reflecting surface component provides multi-functionality by enabling both front-side and lateral-side irradiation modes from a single endoscope position. This universal component allows the same endoscope configuration to handle various treatment scenarios, eliminating the need for multiple specialized configurations

Function Achieved in This Case
Enables reliable irradiation of treatment sites on both lateral and front sides, improving the accuracy and effectiveness of light therapy by allowing for mirror image correction and flexible positioning of the therapeutic light source relative to the treatment area.
Implementation Method 1
a reflecting surface disposed on a path of a therapeutic light emitted in a first direction from an insertion section of an endoscope, and configured to switch an irradiation direction of the therapeutic light between the first direction and a second direction intersecting the first direction
