Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic procedures, such as ERCP, face challenges in accurately determining the alignment of the endoscope scope relative to the intestinal tract direction, leading to potential misalignment and incorrect recognition of anatomical structures like the duodenal papilla.
Innovation Solution
A medical support device and method that utilizes image recognition and machine learning to acquire intestinal tract direction-related information based on geometrical characteristics, providing deviation amount information and posture adjustment support to align the endoscope scope correctly with the intestinal tract direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If endoscopic procedures are performed without image recognition assistance, then the procedure can be performed with simpler equipment, but the accuracy of determining alignment between endoscope scope and intestinal tract direction deteriorates
Solution Approach 1:
The patent introduces an image recognition unit as an intermediary component that processes images from the endoscope camera and provides directional information about the intestinal tract. This mediator enables accurate alignment determination without requiring complex mechanical alignment systems, resolving the contradiction by adding computational intelligence rather than mechanical complexity.
Solution Approach 2:
The patent replaces mechanical alignment systems with an image-based recognition system. Instead of using mechanical sensors or physical alignment guides, the system uses image recognition algorithms to determine the intestinal tract direction and calculate deviation angles, substituting mechanical measurement with optical and computational methods.
2Reliability
If the endoscope scope is inserted without real-time posture information, then the insertion process is faster and simpler, but the reliability of anatomical structure recognition deteriorates
Solution Approach 1:
The patent performs image recognition and posture determination in advance during the insertion process, providing real-time feedback about the endoscope's orientation relative to the intestinal tract. This preliminary action allows the operator to adjust the scope position before reaching critical anatomical structures, ensuring reliable recognition without requiring post-insertion adjustments.
Solution Approach 2:
The system provides continuous feedback to the operator by calculating and displaying the deviation angle between the endoscope scope axis and the intestinal tract direction. This real-time feedback enables dynamic adjustment of the scope posture, ensuring accurate alignment with anatomical structures while maintaining insertion speed through informed operational decisions.
3Ease of operation
If deviation amount information is not provided, then the device remains simpler to operate, but the ease of adjusting endoscope posture deteriorates
Solution Approach 1:
The patent uses visual indicators and color coding to represent the deviation angle and posture alignment status. By translating complex angular data into intuitive visual displays, the system makes posture adjustment information easily perceivable at a glance, allowing operators to quickly understand and correct misalignment without processing complex numerical data.
