    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.
