Guideline Visualization for Image-Guided Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons face uncertainty when following precise medical guidelines during image-guided surgery, as they can only remember a few guidelines at a time and may approximate compliance with constraints, leading to potential undesired results.
Innovation Solution
A method and apparatus that visually display anatomical images with instrument representations and guidelines, providing direct visual feedback on whether procedural constraints are being met, allowing surgeons to focus on other aspects of the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surgeons rely on memory to remember procedural guidelines during operation, then they can maintain focus on the procedure, but they can only remember a few guidelines at a time leading to uncertainty and potential errors
Solution Approach 1:
The system provides real-time visual feedback by displaying guideline representations overlaid on the anatomical image. The guideline visualization dynamically updates based on the instrument's position, giving immediate feedback to the surgeon about compliance with procedural constraints without requiring memory of multiple guidelines simultaneously.
Solution Approach 2:
The patent introduces a visual intermediary representation that translates complex procedural guidelines into intuitive graphical overlays. This intermediary visualization mediates between the surgeon's actions and the procedural requirements, eliminating the need to rely solely on memory while maintaining focus on the procedure.
2Manufacturing precision
If guidelines are stated precisely with specific constraints, then procedural accuracy is improved, but the surgeon must remember and interpret multiple precise constraints simultaneously which increases cognitive load and uncertainty
Solution Approach 1:
The patent segments complex procedural guidelines into multiple independent visual representations, each corresponding to a specific constraint or guideline. Each guideline is displayed as a separate visual element (e.g., colored zones, boundaries, or markers) that can be independently interpreted, reducing the cognitive load of managing multiple precise constraints simultaneously.
Solution Approach 2:
The system uses color coding to represent different types of guidelines and constraint zones. Different colors indicate different procedural requirements or risk levels, allowing surgeons to quickly perceive and prioritize constraints without needing to remember the precise wording of each guideline. The visual differentiation reduces complexity while maintaining precision.
3Productivity
If surgeons approximate compliance with guidelines based on image representation, then they can operate efficiently, but uncertainty arises about whether precise constraints are being fulfilled
Solution Approach 1:
The system provides continuous visual feedback that shows the real-time relationship between the instrument position and guideline constraints. The guideline visualization updates dynamically as the instrument moves, giving immediate confirmation of compliance without requiring the surgeon to mentally calculate or approximate whether constraints are met, thus eliminating uncertainty while maintaining efficiency.
