Three-Dimensional Transforming Surgical Models for Osteotomy Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical demonstration models using human and animal cadavers are costly and create biohazard waste issues, and their chemical preservation alters tissue properties, limiting their effectiveness.
Innovation Solution
Development of three-dimensional transforming models that replicate osteotomy surgical procedures, allowing for customizable, patient-specific demonstrations of bone and ligament structures using replicas or actual bones treated with preservation techniques, and utilizing magnets for alignment and transformation to illustrate pre- and post-surgical states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cadaver specimens are used for surgical demonstration, then anatomical accuracy is improved, but cost and biohazard waste issues worsen
Solution Approach 1:
The patent creates anatomically accurate models that replicate the geometry and structure of actual bones and ligaments without using real cadaver tissue. These models are manufactured copies that preserve the educational value while eliminating biohazard waste and cost issues associated with cadaver specimens.
Solution Approach 2:
The patent transforms the physical state and composition of the demonstration medium from organic cadaver tissue to synthetic or preserved materials. By changing the material parameters while maintaining anatomical fidelity, the model achieves accuracy without the harmful properties of biological waste.
2Shape
If chemical preservation is applied to cadaver tissues, then anatomical geometry is maintained, but tissue physical properties are altered
Solution Approach 1:
Instead of preserving actual tissue, the patent manufactures models that copy the external geometry and structural relationships of bones and ligaments. This approach maintains anatomical accuracy for educational purposes while avoiding the physical property alterations that occur during chemical preservation.
Solution Approach 2:
The patent applies different materials and preservation techniques to different components of the model. Bones may be represented by rigid materials while ligaments use flexible materials, allowing each component to maintain its characteristic physical properties without the uniform degradation caused by chemical preservation.
3Manufacturing precision
If three-dimensional transforming models are developed, then surgical planning precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the surgical model into separate, modular components including individual bones, ligaments, and surgical instruments. This segmentation allows each component to be manufactured with high precision independently, then assembled to create the complete three-dimensional transforming model, managing complexity through modularity.
Solution Approach 2:
The patent creates a dynamic model that can transform between different surgical scenarios and anatomical positions. The model includes movable components and adjustable elements that allow it to demonstrate various surgical techniques and outcomes, providing comprehensive surgical planning capability without requiring multiple static models.
