Percutaneous Coronary Intervention Simulator with Dynamic Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training systems for percutaneous coronary interventions lack customization options, leading to instructors relying on a limited set of training cases and reducing the effectiveness of the diagnostic phase, as they are pre-configured with fixed vessel descriptions, which does not allow for realistic simulation of various lesion scenarios.
Innovation Solution
A computer-implemented method and system that allows trainers to customize training scenarios by selecting lesion positions and properties, such as length, occlusion percentage, and TIMI flow grade, and generating haptic feedback and electrocardiogram graphs based on these inputs, enabling a more realistic and varied training experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If training systems use fixed pre-configured training cases with extensive libraries, then the system structure is simplified and easier to operate, but the adaptability and customization options are reduced
Solution Approach 1:
The system dynamically generates training cases by combining vessel templates with lesion characteristics. Instead of using fixed pre-configured cases, the system allows real-time customization where trainers can select vessel types, lesion positions, and properties, and the system dynamically assembles appropriate training scenarios with corresponding haptic feedback and ECG data.
Solution Approach 2:
The training case library is segmented into modular components: vessel templates, lesion characteristics, haptic feedback parameters, and ECG data sets. This segmentation allows independent selection and combination of components to create customized training scenarios without requiring complete pre-configured cases.
2Device complexity
If training cases are pre-configured with fixed vessel descriptions, then the device complexity is reduced, but the realism and effectiveness of diagnostic phase simulation are compromised
Solution Approach 1:
Vessel templates and lesion characteristics are pre-prepared and stored in the system memory. During training, these pre-prepared elements are quickly assembled and configured based on trainer selections, allowing rapid generation of realistic diagnostic scenarios without requiring complex real-time computation or intricate device configuration.
3Quantity of substance
If extensive libraries of individual training cases are provided, then the completeness of training content is improved, but the ease of operation decreases due to instructor intimidation
Solution Approach 1:
The system provides a universal interface for creating and selecting training cases. The same system infrastructure supports both simple and complex training scenarios, allowing trainers to easily navigate the extensive library through a unified selection mechanism that adapts to their skill level and training needs.
