Objective To design an interventional cardiology simulation system based on Unity3D virtual reality technology to achieve cardiac interventional training, which can simulate multiple sensory feedback in interventional cardiology. Methods The 3Dmax and Unity3D engines were used to construct the 3D cardiovascular model. The virtual reality environment was simulated by Novint Falcon and Oculus Rift hardware and software to simulate the interventional procedure of the guide wire. Results With the Novint Falcon force feedback controller, users can practice a variety of virtual instruments for percutaneous transluminal coronary angioplasty and restore the surgical scene with the Oculus Rift virtual reality device, resulting in better simulation results. Conclusion A simulation system for interventional surgery was designed, which aided a wide range of medical training and simulation studies.
