Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual simulation surgery is performed without accurate tool representation, then the basic environment for virtual surgery is incomplete, but the precision and effectiveness of virtual surgical planning deteriorates
Solution Approach 1:
The patent creates virtual copies of actual surgical tools by capturing images of real tools and generating corresponding virtual tool models. These virtual copies are then calibrated against actual tool movements during surgery, ensuring that the virtual representation accurately mirrors the physical tool's behavior. This copying approach resolves the contradiction by providing both the completeness of virtual tool representation and the precision needed for effective surgical planning.
Solution Approach 2:
The patent employs parameter calibration techniques where virtual tool parameters (position, orientation, movement轨迹) are adjusted and synchronized with actual surgical tool parameters. By dynamically updating virtual tool parameters based on real-time surgical data, the system maintains high accuracy in virtual simulation while preserving the precision required for surgical planning and prediction.
2Measurement precision
If correspondence matching and calibration processes are implemented, then the representation of surgical tools improves, but the complexity of the virtual reality system increases
Solution Approach 1:
The patent introduces calibration algorithms as intermediary processes that bridge the gap between actual surgical tools and their virtual representations. These calibration intermediaries automatically perform correspondence matching by comparing visual features of real tools with virtual model features, establishing accurate mappings without requiring complex manual configuration. This intermediary approach achieves high measurement precision while managing system complexity through automated processing.
3Reliability
If log information is generated based on coordinate differences, then the prediction of surgical tool movement improves, but the processing time and computational load increase
Solution Approach 1:
The patent performs preliminary calibration of virtual surgical tools before actual surgery begins. During this pre-surgical phase, the system captures images of actual tools, generates virtual models, and establishes correspondence relationships in advance. This preliminary action allows the system to store pre-computed calibration data and coordinate mappings, which can then be quickly applied during surgery without requiring real-time complex calculations, thus improving prediction accuracy while minimizing time loss during the actual surgical procedure.
