Engineering Contradiction Analysis
1Loss of information
If a guidance system provides feedback based on scalar distance between medical device and anatomical structure, then the system is simple to operate, but the information provided to the user is insufficient for comprehensive risk assessment
Solution Approach 1:
The patent transitions from providing only scalar distance information to providing comprehensive risk assessment by incorporating multiple dimensions: anatomical structure geometry (3D shape, orientation), medical device parameters (type, dimensions, orientation), and spatial relationships. This dimensional expansion enables more complete risk assessment while maintaining system operability through automated computational methods.
Solution Approach 2:
The guidance system is enhanced to perform multiple functions: it not only tracks position and calculates distance like traditional systems, but also segments image data to identify anatomical structures, computes geometric parameters, evaluates risk based on multiple factors, and provides comprehensive feedback. This multi-functionality addresses information insufficiency while managing complexity through integrated processing.
2Reliability
If the system computes comprehensive risk assessment based on multiple parameters, then the reliability of surgical planning is improved, but the computational complexity and processing time increase
Solution Approach 1:
The system performs preliminary segmentation of image data to identify anatomical structures and compute their geometric parameters before the actual surgical procedure. This pre-processing establishes a detailed digital model of the anatomical landscape, enabling rapid risk evaluation during the procedure without requiring complex real-time computations for basic geometric analysis.
Solution Approach 2:
The system implements continuous feedback by computing risk assessments based on the current position of the medical device relative to the pre-segmented anatomical structures. This feedback mechanism uses the established digital model to rapidly evaluate risk at each position, providing reliable guidance without requiring repeated complex segmentation and analysis.
3Reliability
If the system provides detailed risk assessment and optimal path planning, then procedural safety is improved, but the time required for surgical planning increases
Solution Approach 1:
The system performs image segmentation and anatomical structure identification in advance before the surgical procedure begins. This preliminary action creates a ready-to-use digital model that enables rapid risk assessment and path planning during the procedure, reducing the time burden on surgeons while maintaining comprehensive safety evaluation.
