Solution Overview
Problem
Current training procedures for invasive percutaneous and endoscopic interventions lack efficiency, with interventionalists not being adequately prepared due to the absence of effective training methods, leading to low success rates and limited visualization of target tissues during procedures.
Innovation Solution
A system and method utilizing a pipe with a stereoscopic camera and real-time 3D model generation to simulate the insertion and movement of tools within a virtual environment, allowing interventionalists to practice and plan interventions safely and effectively, combining real-time 3D modeling of tools with pre-computed organ models for enhanced visualization and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current training procedures are used for invasive percutaneous and endoscopic interventions, then interventionalists can be trained, but the training is inadequate and leads to low success rates
Solution Approach 1:
The patent creates a virtual copy of the procedural environment by generating a 3D model of the procedural site from pre-procedural imaging data. This virtual model replicates the anatomical structures, pathology, and procedural conditions, allowing interventionalists to practice in a realistic simulation without risking patient safety. The copying principle enables thorough training while maintaining high reliability by eliminating the gap between training and actual procedure conditions.
2Ease of operation
If more training time and practice opportunities are provided, then interventionalists can be better prepared, but patient risk and intervention time increase
Solution Approach 1:
The patent introduces a virtual simulation environment as an intermediary between training and actual patient procedures. This intermediary allows interventionalists to accumulate extensive practice experience with unlimited repetitions, mastering complex skills before encountering real patients. The virtual environment acts as a safe buffer that eliminates patient risk while providing comprehensive training, resolving the contradiction between preparedness and patient safety.
3Productivity
If current voltage mapping techniques are used for visualization, then the procedure can be performed, but the visualization of target scar tissue is limited and control of ablation lesion formation is imperfect
Solution Approach 1:
The patent creates a precise virtual copy of the procedural site with enhanced visualization capabilities. The 3D model reconstructs anatomical structures, tissue properties, and pathology with high fidelity, allowing interventionalists to visualize target scar tissue and plan ablation lesions with greater precision before the actual procedure. This virtual copying enables improved measurement precision while maintaining procedural efficiency through pre-planning.
Solution Approach 2:
The patent enables preliminary action by allowing interventionalists to plan and simulate the entire procedure, including ablation lesion formation, before entering the actual procedural room. The virtual environment permits pre-procedural planning, optimization of ablation parameters, and rehearsal of complex maneuvers, improving both visualization accuracy and procedural efficiency by resolving uncertainties in advance.
4Reliability
If extensive training and pre-procedural planning are implemented, then intervention success rate improves, but time occupancy of endoscopic intervention rooms increases
Solution Approach 1:
The patent applies preliminary action by enabling comprehensive pre-procedural planning and simulation in a virtual environment. Interventionalists can optimize their approach, identify potential challenges, and rehearse complex maneuvers before the actual procedure. This advance preparation reduces time occupancy during the actual intervention by eliminating uncertainties and enabling more efficient execution, thereby improving success rate without sacrificing time efficiency.
