Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Observing capillary vessels in the near-surface region of a living organ is challenging due to their small size and synchronization with heartbeats, making it difficult to detect lesions like cancer using conventional endoscopes.
Innovation Solution
An endoscope with an illumination window and observation window at its distal end, equipped with a blood flow changing section that uses temperature change or vibration energy to alter blood flow, allowing for better visualization of capillary vessels by increasing blood flow through the application of thermal or vibrational energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional endoscope observation is used, then the observation structure is simple, but the capillary vessels cannot be clearly observed due to their small size and heartbeat synchronization
Solution Approach 1:
The patent applies parameter changes by introducing temperature control and vibration parameters to the observation system. The temperature changer modifies the thermal state of the observed object to stabilize blood flow, while the vibration generator applies mechanical vibration to enhance capillary vessel visibility. These parameter modifications transform the observation conditions to make previously unobservable capillary vessels visible, resolving the contradiction between observation precision and device complexity.
Solution Approach 2:
The patent directly applies mechanical vibration by incorporating a vibration generator that vibrates the observation optical system. This vibration enhances the visibility of capillary vessels by creating dynamic optical effects that make the tiny, heartbeat-synchronized vessels distinguishable from surrounding tissue. The vibration principle directly addresses the observation precision problem without requiring complex structural modifications to the endoscope itself.
2Measurement precision
If temperature change or vibration energy is applied to change blood flow, then the visibility of capillary vessels is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent merges multiple functions into the endoscope system by integrating the temperature changer, vibration generator, and observation windows into a single integrated device. This combining approach allows the system to perform blood flow modification and observation functions simultaneously, improving blood flow observation precision while managing device complexity through functional integration rather than separate independent systems.
Solution Approach 2:
The endoscope system is designed with multi-functionality, serving both as a standard observation device and as a blood flow control device. The temperature changer and vibration generator are incorporated to provide blood flow modification capabilities, while the illumination and observation windows handle both general tissue observation and specific capillary vessel observation. This universal design allows one device to perform multiple functions, addressing the precision improvement need while controlling complexity through functional consolidation.
