Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microsurgical training models lack the natural three-dimensionality needed to accurately simulate complex clinical procedures, leading to inadequate training for surgeons in performing anastomosis under unique vessel positions and angles, and they are costly and ethically challenging due to the use of live animals.
Innovation Solution
A 3D-printed training device with a ball-in-socket joint mechanism that allows for the secure positioning and angulation of vascular tissue, enabling precise simulation of microsurgical anastomosis procedures, which can be easily assembled and customized using thermoplastic polyurethane materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional training models (animal models, simple tubes) are used, then basic microsurgical techniques can be practiced, but they lack the natural three-dimensionality needed for complex clinical procedures with unique vessel positions and angles
Solution Approach 1:
The patent transitions from flat, two-dimensional training models to a three-dimensional ball-in-socket joint mechanism that enables vessels to be positioned at multiple angles and orientations, accurately replicating complex clinical microsurgical scenarios with unique spatial configurations
Solution Approach 2:
The ball-in-socket joint provides dynamic adjustability, allowing the upper platform to be rotated and angled relative to the base, enabling trainees to practice anastomosis at various vessel orientations and positions rather than being constrained to fixed angles
2Reliability
If live animal models are used for training, then realistic surgical practice is achieved, but ethical concerns and high costs arise
Solution Approach 1:
The patent creates a realistic synthetic copy of the clinical surgical environment using a ball-in-socket mechanism with adjustable vessel positioning, allowing trainees to practice on artificial models that replicate the complexity of live surgery without the ethical and cost issues of animal models
Solution Approach 2:
The training device uses inexpensive, replaceable synthetic vessels and a simple mechanical structure that can be easily manufactured and disposed of, eliminating the need for expensive and ethically problematic live animal models while maintaining training effectiveness
3Ease of manufacture
If simple tube models are used for training, then basic techniques can be practiced, but they fail to model complex clinical procedures with unique three-dimensional vessel positions
Solution Approach 1:
The ball-in-socket joint mechanism allows dynamic repositioning of vessels at various angles and orientations, enabling the same simple model to simulate multiple complex clinical scenarios rather than requiring different fixed models for each procedure type
Solution Approach 2:
The universal ball-in-socket platform can accommodate various vessel sizes and configurations through angle adjustment, making it a multi-functional training tool that replaces multiple specialized models while maintaining ease of manufacture
