Healable Synthetic Tissue for Reusable Surgical Trainers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical training methods using synthetic tissues are expensive and environmentally unfriendly due to their single-use nature, as they cannot be reused after procedures, and they lack the ability to mimic the healing properties of biological tissues.
Innovation Solution
Development of healable synthetic tissues that utilize self-healing materials such as hydrogen bonding, ionic bonding, and dynamic covalent bonds, which can re-bond after incisions, allowing for multiple uses and incorporating sensors for feedback during training, along with a modular manikin design for comprehensive surgical training simulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-use synthetic tissues are used for surgical training, then training procedures can be performed, but the cost increases and environmental friendliness decreases due to inability to reuse
Solution Approach 1:
The synthetic tissue incorporates dynamic chemical bonds (hydrogen bonds, ionic bonds, covalent bonds) that can reversibly change their bonding state. When cut, the bonds break allowing separation; when heated or stimulated, the bonds reform allowing healing. This parameter change enables the tissue to transition from a single-use state to a reusable healed state, resolving the contradiction between training effectiveness and material waste
Solution Approach 2:
The synthetic tissue contains self-healing capabilities through embedded healing agents or reactive groups that automatically react when brought into contact after cutting. The tissue can autonomously repair its own structure without external intervention, enabling multiple uses and reducing material waste while maintaining training reliability
2Shape
If traditional synthetic materials like silicone or polyurethane are used, then tissue simulation is achieved, but reusability is limited and expense increases
Solution Approach 1:
The patent combines traditional synthetic tissue materials (silicone, polyurethane) with self-healing components containing dynamic bonds and healing agents. This composite structure maintains the realistic tissue simulation properties of the base materials while adding the self-healing capability that enables repeated use, thus resolving the contradiction between shape realism and trainer reusability
3Productivity
If healable synthetic tissues with multiple bonding mechanisms are used, then reusability improves, but device complexity increases
Solution Approach 1:
The self-healing mechanism operates autonomously through built-in chemical reactions without requiring external complex systems. The tissue contains healing agents or reactive groups that automatically react when conditions are met (contact, heat, moisture), eliminating the need for complex external healing equipment and reducing overall device complexity while maintaining high reusability
