Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope insertion shape analysis systems face challenges in accurately detecting the insertion shape and position of the endoscope within the body cavity, particularly in curved areas, which can lead to difficulties in smoothly inserting the endoscope and may cause discomfort or damage to the patient.
Innovation Solution
The system includes an insertion state acquisition unit for acquiring coordinate values, an insertion shape detection unit for analyzing the insertion shape, a coordinate plane setting unit for projecting shapes onto multiple planes, and a judging unit to determine if a predetermined shape exists, allowing for real-time feedback on insertion shape and potential stop points to assist the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the endoscope insertion shape analysis system uses conventional single-plane detection methods, then the device complexity is low, but the measurement precision of insertion shape in curved body cavities deteriorates
Solution Approach 1:
The patent projects the insertion shape onto multiple coordinate planes (X-Y, Y-Z, and Z-X planes) to analyze the three-dimensional shape from different dimensional perspectives. This multi-plane projection approach enables accurate detection of loop shapes and insertion curvature that cannot be captured by single-plane detection, directly resolving the contradiction between measurement precision and device complexity.
2Reliability
If the system detects loop shapes and insertion stop points in real-time, then the reliability of insertion operation is improved, but the loss of time for processing and analyzing coordinate data increases
Solution Approach 1:
The system pre-calculates and stores the normal vectors of multiple coordinate planes before actual insertion detection. During real-time operation, the system only needs to project detected coordinate values onto these pre-prepared planes and compare with stored loop shape criteria, significantly reducing processing time while maintaining high reliability in loop detection and insertion stop point identification.
3Ease of operation
If the endoscope insertion portion is made more flexible to navigate curved body cavities, then the ease of operation is improved, but the stability of the insertion portion position deteriorates
Solution Approach 1:
The system continuously monitors the insertion shape by detecting coordinate values at multiple locations along the insertion portion and projecting them onto multiple coordinate planes. Real-time feedback on loop shape formation and insertion curvature enables the operator to adjust the insertion technique, while the system automatically identifies insertion stop points, thereby maintaining position stability without compromising flexibility or ease of operation.
