Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calibration processes are used to track surgical instruments, then tracking accuracy can be achieved, but the calibration time becomes excessively long and complex
Solution Approach 1:
The system performs preliminary calibration by pre-defining the spatial relationship between the surgical instrument and tracking fiducials in the surgical plan. This allows the tracking system to be configured in advance, eliminating the need for time-consuming real-time calibration during surgery while maintaining accurate tracking.
Solution Approach 2:
The system creates a virtual copy of the surgical scene including instrument positions and tracking fiducial locations in the treatment plan. This virtual model allows the system to predict and compensate for tracking relationships without requiring physical calibration measurements during the procedure.
2Manufacturing precision
If detailed image guidance data is provided for surgical instruments, then surgical precision is improved, but the system complexity and difficulty of operation increase
Solution Approach 1:
The system automatically calculates and updates image guidance data based on the pre-defined treatment plan and real-time instrument positions. The software self-adjusts the visualization and guidance information without requiring manual configuration or complex user input, maintaining high surgical precision while simplifying operation.
Solution Approach 2:
The system provides real-time feedback by continuously updating the virtual surgical scene with actual instrument positions and predicting future positions based on the treatment plan. This automated feedback loop delivers detailed guidance information without increasing operational complexity, as the system manages the complexity internally.
3Measurement precision
If real-time prediction of instrument positions is implemented, then surgical accuracy is enhanced, but computational requirements and system complexity increase
Solution Approach 1:
The system pre-calculates predicted instrument positions and trajectories as part of the treatment plan before surgery begins. By performing this computational work in advance, the system reduces real-time computational requirements while maintaining high prediction accuracy during the surgical procedure.
Solution Approach 2:
The system maintains a virtual copy of the surgical environment with pre-computed prediction models. This virtual model allows rapid position prediction without requiring complex real-time calculations, as the computational heavy lifting was performed during treatment planning.
