Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical simulation systems lack the ability to provide a realistic and accurate training experience for medical procedures, particularly endovascular procedures, due to the challenges of manipulating multiple tools with limited tactile feedback and depth perception on flat video displays.
Innovation Solution
A medical simulation system that provides real-time, high-accuracy training with both visual and haptic feedback, allowing for the manual manipulation of multiple tools and incorporating a haptic force feedback mechanism to simulate the resistance levels encountered during medical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a flat video display is used to show tool bearings during medical procedures, then visual information is provided, but depth perception is lacking and spatial understanding is difficult
Solution Approach 1:
The patent introduces an intermediary device (stereoscopic display system or augmented reality overlay) that translates 2D video information into 3D spatial representation, allowing physicians to perceive depth and spatial relationships without changing the fundamental 2D display technology
Solution Approach 2:
The patent creates a virtual copy of the procedural environment with accurate spatial relationships and depth information that can be overlaid on or viewed alongside the actual procedure, allowing physicians to understand tool bearings in three dimensions while maintaining the simplicity of standard displays
2Adaptability or versatility
If multiple operational tools are manipulated during endovascular procedures, then procedural capability is enhanced, but tactile feedback is limited and coordination difficulty increases
Solution Approach 1:
The patent implements a feedback system that provides real-time tactile or haptic feedback to the physician during tool manipulation, enabling sensing of tool positions and forces applied to patient tissues, thereby improving coordination and control of multiple tools simultaneously
Solution Approach 2:
The patent creates a universal control interface that can handle multiple different operational tools through a single standardized manipulation mechanism, reducing the cognitive load and coordination difficulty associated with managing diverse tool types
3Reliability
If realistic training simulation is provided for medical procedures, then training accuracy is improved, but system complexity and cost increase
Solution Approach 1:
The patent uses virtual reality or augmented reality to create a digital copy of the procedural environment, patient anatomy, and tool interactions, providing realistic training feedback without requiring expensive and complex physical simulation hardware
Solution Approach 2:
The patent replaces complex mechanical simulation systems with software-based virtual or augmented reality environments that can provide equivalent or superior training accuracy while reducing hardware complexity and cost
