Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teleoperated surgical training systems lack effective methods for providing consistent and efficient training experiences, particularly in cooperative environments, which are crucial for mastering robotic surgical skills and reducing training time.
Innovation Solution
A virtual training environment is developed that integrates a local user's virtual surgical instruments with an expert user's instruments, allowing for real-time cooperative training through a composite display of both users' virtual surgical sites, enhanced with graphical overlays and annotations, and utilizing a communication system for data sharing over networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional surgical training methods are used, then training experience consistency can be maintained, but training time and efficiency deteriorate
Solution Approach 1:
The patent creates virtual copies of surgical environments and procedures that can be repeatedly simulated with consistent parameters. The virtual training environment replicates surgical scenarios allowing unlimited repetitions with identical conditions, ensuring training consistency while reducing time investment compared to traditional repeated physical training.
Solution Approach 2:
The system allows dynamic adjustment of training parameters such as difficulty level, procedural complexity, and environmental conditions. By changing these parameters programmatically, the system maintains consistent training quality while adapting to different learning stages, thereby reducing overall training time without sacrificing consistency.
2Reliability
If cooperative training environments are implemented, then training efficacy is improved, but system complexity increases
Solution Approach 1:
The training system is divided into separate functional modules: virtual environment rendering, user input processing, communication protocols, and performance evaluation. Each module operates independently and can be developed, tested, and optimized separately, reducing overall system complexity while enabling sophisticated cooperative training scenarios.
Solution Approach 2:
The patent introduces a communication system as an intermediary layer between trainees and the virtual surgical environment. This mediator handles data exchange, synchronization, and coordination between multiple users, abstracting the complexity of cooperative interaction and presenting a simplified interface to users while maintaining high training efficacy.
3Reliability
If expert-guided feedback is provided, then training consistency is enhanced, but training time increases
Solution Approach 1:
The system implements automated feedback mechanisms that provide real-time guidance and evaluation to trainees. The virtual environment automatically detects actions, compares them against optimal procedures, and provides immediate feedback, eliminating the need for continuous expert presence while maintaining training consistency and reducing overall training time.
Solution Approach 2:
The system provides preliminary guidance and hints before trainees encounter difficulties. By anticipating potential errors and providing preventive guidance, the system reduces the need for corrective feedback loops, thereby maintaining training consistency while reducing the time required for expert intervention and correction.
