Interventional surgery is an efficient and safe surgical method with the advantages of less trauma and quick recovery. However, the current interventional surgery training is mainly based on teachers’ hands-on guidance of the students, which has problems such as low efficiency and high risks. Therefore, to help doctors who want to conduct interventional surgery training, we have designed a virtual interventional surgery training system based on bone model guide wires. By designing the bone model and movement of the guidewire, linking it with the haptic device of Geomagic TOUCH, and reconstructing the real vascular surgery scene, we can simulate the manipulation of doctors on the guidewire during interventional surgery, and evaluate and score the training process to make the training more practical and evaluable. Users can check their operating level and accumulate experience. We then design a simulation of vascular interventional surgery based on magnetic-actuation in this system. The experimental results show that, compared with the traditional interventional surgery simulation mode, simulation based on magnetic-actuation can effectively improve the performance of the trainer. This system is designed to enhance the reality of the surgical simulation process, help trainers become familiar with interventional surgery scenarios, and provide a real practical experience for practicing both traditional and magnetic-actuation interventional surgeries.

摘要

Interventional surgery is an efficient and safe surgical method with the advantages of less trauma and quick recovery. However, the current interventional surgery training is mainly based on teachers’ hands-on guidance of the students, which has problems such as low efficiency and high risks. Therefore, to help doctors who want to conduct interventional surgery training, we have designed a virtual interventional surgery training system based on bone model guide wires. By designing the bone model and movement of the guidewire, linking it with the haptic device of Geomagic TOUCH, and reconstructing the real vascular surgery scene, we can simulate the manipulation of doctors on the guidewire during interventional surgery, and evaluate and score the training process to make the training more practical and evaluable. Users can check their operating level and accumulate experience. We then design a simulation of vascular interventional surgery based on magnetic-actuation in this system. The experimental results show that, compared with the traditional interventional surgery simulation mode, simulation based on magnetic-actuation can effectively improve the performance of the trainer. This system is designed to enhance the reality of the surgical simulation process, help trainers become familiar with interventional surgery scenarios, and provide a real practical experience for practicing both traditional and magnetic-actuation interventional surgeries.
