Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical training programs rely on real patient procedures for skill development, then surgeons gain authentic surgical experience, but the frequency and variety of procedures available for training are insufficient, particularly in underdeveloped areas
Solution Approach 1:
The patent creates realistic anatomical models that replicate human tissue properties, blood flow dynamics, and surgical conditions. These models include synthetic organs with lifelike textures, embedded blood vessels that simulate real blood flow, and tissues that respond to surgical instruments similarly to actual human tissue. By copying the essential characteristics of real surgical environments, trainees can practice procedures repeatedly without needing actual patients.
Solution Approach 2:
The system allows modification of various parameters including blood flow rate, pressure, tissue firmness, and anatomical configuration. The hemodynamic simulator can adjust blood flow characteristics to match different physiological states, while the anatomical models can be changed to represent various pathologies or anatomical variations. This enables diverse training scenarios from a single platform.
2Adaptability or versatility
If more surgical procedures are performed in training hospitals to provide adequate practice opportunities, then trainee proficiency improves, but resource constraints in underdeveloped areas and smaller hospitals limit the availability of such procedures
Solution Approach 1:
The surgical training system is designed as a universal platform that can simulate multiple different surgical procedures and anatomical regions. The modular anatomical models can be configured to represent various organs and tissue types, allowing a single system to provide training for diverse surgical specialties. The hemodynamic simulator works with different anatomical configurations to simulate various physiological conditions.
3Productivity
If anatomical models are used for surgical training, then practice opportunities increase, but the models must realistically simulate blood flow dynamics and tissue properties to be effective
Solution Approach 1:
The system employs a hemodynamic simulator that uses fluid dynamics to replicate blood flow through anatomical models. The simulator incorporates pumps, pressure regulators, and flow meters to control and monitor simulated blood flow characteristics. The anatomical models include embedded channels that mimic blood vessels, allowing realistic simulation of arterial and venous flow patterns, pressure gradients, and tissue perfusion.
