Virtual Organ Simulation via Tensioned Element Networks

The surgical procedure simulation is divided into multiple independent physical models: tool models for different surgical instruments, organ models for different body tissues, and interaction models for tool-organ contacts. Each model can be processed independently in real-time, reducing overall computational complexity while maintaining comprehensive simulation accuracy.

The simulation system dynamically adjusts the level of physical model complexity based on the current surgical context. Different tissue types use different mechanical models (e.g., hyperelastic models for soft tissues, rigid models for bones), and the system selectively activates appropriate interaction models only when relevant tools contact relevant organs, optimizing real-time performance.

A unified physics engine is developed that can handle multiple types of physical models (rigid bodies, deformable tissues, fluid dynamics, thermal effects) within a single computational framework. This allows the system to simulate diverse surgical procedures using the same core infrastructure, maintaining real-time performance while achieving comprehensive simulation coverage.

The simulation applies different levels of physical model detail to different regions of the surgical scene. High-fidelity models are used only in the immediate vicinity of tool-tissue interactions, while distant regions use simplified models or are excluded from computation entirely. This localized approach maintains comprehensive simulation where needed while preserving real-time processing capability.
