A novel dynamic cardiac simulator utilizing pneumatic artificial muscle.
Summary
This study introduces a novel dynamic cardiac simulator using pneumatic artificial muscle for realistic heartbeat simulation. The device effectively mimics human systolic pressure, enhancing surgical training for cardiovascular procedures.
Area of Science:
- Biomedical Engineering
- Medical Simulation
- Cardiovascular Devices
Background:
- Minimally invasive surgery requires advanced training tools.
- Cardiovascular surgery demands familiarity with beating heart dynamics.
- Existing simulators may lack realistic cardiac motion.
Purpose of the Study:
- To develop a dynamic cardiac simulator with a realistic heartbeat.
- To utilize pneumatic artificial muscle for simulating cardiac systole and diastole.
- To provide a training tool for cardiovascular surgeons.
Main Methods:
- Constructed an artificial left ventricle using thermoplastic elastomers (TPE) with anatomical accuracy.
- Integrated a pneumatic artificial muscle layer for omnidirectional actuation.
- Performed preliminary experiments to assess simulator performance.
Main Results:
- The simulator successfully mimicked the systole and diastole of a human heart.
- Achieved controllable aortic terminal pressure within the normal human systolic range.
- Demonstrated the effectiveness of the pneumatic artificial muscle actuation mode.
Conclusions:
- The developed dynamic cardiac simulator provides a realistic training environment.
- Pneumatic artificial muscle technology is effective for simulating heartbeats.
- This simulator can enhance surgical skills for cardiovascular procedures.
