Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual surgery simulation is used for training surgeons, then training accessibility and repeatability are improved, but the ability to objectively evaluate surgeon skill level deteriorates
Solution Approach 1:
The system implements automated feedback by capturing surgical instrument parameters during virtual surgery simulation, comparing them against pre-established evaluation indexes, and providing objective skill level assessments. This feedback mechanism transforms the training system from purely experiential to data-driven evaluation.
Solution Approach 2:
The patent replaces subjective human evaluation with automated computational analysis. Surgical instrument parameters are automatically captured and processed by a computer system that compares them against evaluation indexes, substituting manual assessment with algorithmic evaluation to achieve objective skill measurement.
2Measurement precision
If detailed surgical instrument parameters are captured for evaluation, then evaluation accuracy is improved, but system complexity and data processing requirements worsen
Solution Approach 1:
The system extracts only the essential surgical instrument parameters needed for evaluation from the complex virtual surgery simulation data. By identifying and isolating key parameters such as instrument position, orientation, and operational metrics, the system reduces data complexity while maintaining evaluation accuracy.
Solution Approach 2:
Evaluation indexes are pre-established and stored before the actual skill assessment takes place. These pre-defined criteria include threshold values and comparison standards that are prepared in advance, allowing the system to process captured parameters efficiently without complex real-time decision-making logic.

AI summary
Disclosed is an apparatus for evaluating a virtual surgery based on an evaluation index. The present embodiment provides an apparatus for evaluating a virtual surgery based on an evaluation index, which is capable of: generating an evaluation index based on an average point of three-dimensional coordinates which are obtained through a repeated performance of a virtual simulation by an operating surgeon (evaluator) with a high surgical skill level; and extracting the three-dimensional coordinates obtained in a process of performing the virtual simulation by a surgeon-in-training (subject) with a low surgical skill level and comparing the same with the above-generated evaluation index so as to evaluate the virtual surgery performed by the surgeon-in-training.
