Haptic reproduction and interactive visualization of a beating heart for cardiovascular surgery simulation

Area of Science:

• Medical Simulation
• Biomedical Engineering
• Haptic Technology

Background:

• Current cardiac surgery simulators lack realistic haptic feedback and dynamic tissue simulation.
• Interactive simulation of active tissues, like a beating heart, remains a challenge.

Purpose of the Study:

• To develop a novel framework for real-time, interactive simulation of a beating heart for surgical training.
• To achieve accurate haptic reproduction and visualization of cardiac motion during simulated surgery.

Main Methods:

• Utilized time series datasets of cardiac motion for simulation.
• Developed a framework for collision detection and response between a surgical manipulator and a virtual heart.
• Implemented physics-based force feedback using a stress-pressure model for autonomous cardiac motion.

Main Results:

• Successfully integrated a force feedback device with a simulation system for a beating heart.
• Demonstrated a multi-dimensional representation of a beating heart for surgical palpation training.
• Validated the framework's quality and performance through measurements and medical assessment.

Conclusions:

• The proposed framework provides a foundational training environment for surgical palpation.
• The system effectively reproduces haptic sensations and real-time visualization of a beating heart.
• This approach advances the development of realistic surgical simulators.
