Endoscope System Automatic Positioning via Library Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscope systems require significant operator effort to adjust the endoscope's position and attitude to achieve optimal viewing angles during procedures, lacking efficient methods to automatically align the imaging optical system with the observation object based on procedural scenes.
Innovation Solution
An endoscope system comprising an imaging optical system, an electric arm, a field-of-view direction changing unit, and a storage apparatus that uses library data associated with procedural scenes to control the endoscope's position, attitude, and field-of-view direction, incorporating relative parameters like inclination and curvature to align the imaging optical system with the observation object.

Engineering Contradiction Analysis
1Ease of operation
If the operator manually adjusts the endoscope position and attitude to achieve optimal viewing angles, then the endoscope can be positioned correctly, but the operator effort and time consumption increase significantly
Solution Approach 1:
The system pre-stores optimal endoscope position and attitude data (library data) for various procedural scenes. When a procedural scene is detected, the corresponding pre-calculated position and attitude parameters are automatically retrieved and applied, eliminating the need for manual adjustment during the procedure.
Solution Approach 2:
The system automatically detects the current procedural scene using image recognition, retrieves the appropriate library data, and adjusts the endoscope position and attitude without operator intervention. The system serves itself by autonomously completing the positioning task that would otherwise require manual operation.
2Extent of automation
If the system automatically adjusts the endoscope based on library data, then operator effort is reduced, but the system complexity increases
Solution Approach 1:
The control device performs multiple functions: it detects procedural scenes using image recognition, retrieves appropriate library data, calculates endoscope position and attitude parameters, and controls the positioning mechanism. By consolidating these functions into a single control device, the system manages complexity through functional integration rather than adding separate components.
Solution Approach 2:
The system stores and retrieves parameter sets (position and attitude data) for different procedural scenes. By changing parameters rather than physically reconfiguring the system, the automation achieves adaptability across different surgical scenarios without increasing hardware complexity.
3Measurement precision
If manual adjustment is used to achieve precise endoscope positioning, then accurate field of view is obtained, but the procedural efficiency decreases
Solution Approach 1:
Optimal position and attitude parameters are pre-calculated and stored in the library during the setup phase. During actual procedures, these pre-computed parameters are simply retrieved and applied, achieving both high positioning accuracy and fast execution without requiring manual adjustment time.
Solution Approach 2:
The system continuously monitors the procedural scene through image recognition, detects changes in the surgical context, and automatically retrieves updated library data to maintain optimal positioning. This closed-loop feedback ensures accurate positioning adapts dynamically to procedural changes without operator intervention.
