Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulation technologies for the human thorax are limited to component analysis or crash/accident simulation, failing to provide detailed, person-specific, non-linear static simulations necessary for the development and optimization of surgical methods and materials.
Innovation Solution
A process and apparatus for thorax simulation modeling that involves receiving and processing imaging data to generate component data representing thoracic body parts, including joints, and applying compressive loads to simulate structural properties, using a compression plate and strapping system for medical imaging, enabling the creation of a person-specific simulation model.

Engineering Contradiction Analysis
1Reliability
If component analysis or crash simulation is used for thorax simulation, then development time and cost are reduced, but the simulation accuracy and detail for surgical applications are insufficient
Solution Approach 1:
The thorax is segmented into multiple anatomical components (ribs, sternum, costal cartilages, joints) that are modeled and simulated separately. Each component can be analyzed independently while maintaining their spatial relationships, allowing detailed surgical simulation without requiring a complete complex system model.
Solution Approach 2:
The simulation system allows modification of material properties and structural parameters of thoracic components to match specific patient anatomy. By changing parameters such as bone density, cartilage elasticity, and joint properties based on patient-specific data, the system achieves accurate surgical simulation without increasing overall system complexity.
2Adaptability or versatility
If general thorax simulation is used, then applicability is broad, but person-specific anatomical characteristics cannot be accounted for
Solution Approach 1:
Patient-specific anatomical data is collected and processed in advance through imaging and scanning procedures. The thoracic components are pre-modeled and positioned according to the patient's actual anatomy before surgical simulation begins, enabling personalized simulation without increasing real-time computational burden.
Solution Approach 2:
A digital copy or replica of the patient's thoracic anatomy is created using imaging data. This virtual model replicates the patient's specific anatomical characteristics including bone structures, joint positions, and tissue properties, allowing surgical methods to be tested on the copy before actual surgery.
3Manufacturing precision
If detailed non-linear static simulation is performed, then surgical method optimization is improved, but computational resources and time requirements increase
Solution Approach 1:
The complex non-linear simulation is divided into separate analyses for different thoracic components. Each component (ribs, sternum, joints) is simulated independently with appropriate boundary conditions, reducing the overall computational complexity while maintaining the accuracy needed for surgical method optimization.
