AI Technical Summary
Existing surgical training methods, particularly for laparoscopic procedures, face challenges in replicating the three-dimensional environment and tactile sensations, and require complex and costly sanitation for live organs, while current artificial organs lack sufficient realism and realism-specific targeting for laparoscopic training.
A method involving the application of uncured silicone to stretched elastic materials or meshes to create simulated tissue structures with residual stresses, mimicking natural anatomical features by incorporating prefabricated pieces or sheets, and using less complex molds to achieve realistic curves and tactile properties.
The method produces simulated tissue structures that accurately mimic natural anatomical features, providing enhanced realism and tactile feedback, reducing training complexity and costs, and allowing for effective skill development outside the operating room.
