Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synthetic models for suturing techniques lack feedback on accuracy, which can lead to poor wound healing and scarring, and require live models for hands-on training, increasing risks associated with inexperienced medical personnel.
Innovation Solution
A suture training system incorporating a three-dimensional tracking system with light-reflective markers and a processing unit to provide real-time feedback on suturing accuracy, including location and depth, eliminating the need for live models and reducing risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If synthetic models are used for suturing training, then hands-on practice is enabled, but feedback on accuracy is not provided
Solution Approach 1:
The patent implements a feedback system using light-reflective markers on the suture needle and detectors that track the needle's position and depth in real-time. This provides immediate feedback to trainees on the accuracy of their suturing technique, resolving the contradiction by enabling both hands-on practice and accurate feedback measurement.
Solution Approach 2:
The patent replaces traditional mechanical measurement methods with an optical tracking system. Light-reflective markers on the needle are detected by optical sensors to determine needle position and depth, substituting complex mechanical measurement systems with a simpler optical field-based approach that enables real-time feedback.
2Reliability
If live models are used for suturing training, then real-time feedback is possible, but risks associated with inexperienced personnel increase
Solution Approach 1:
The patent uses a synthetic training model that copies the essential anatomical features needed for suturing practice without the risks associated with live human models. The synthetic model includes integrated tracking systems that provide reliable feedback while eliminating the harmful factors of using actual human subjects for training.
3Loss of information
If tracking system components are added to synthetic models, then feedback capability is provided, but device complexity increases
Solution Approach 1:
The patent divides the tracking system into discrete, modular components: light-reflective markers attached to the needle, optical detectors positioned at specific locations, and a processing unit. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and less complex while maintaining full feedback capability.
