Design of Emergency Training System for Lower Limb Fracture Surgery Based on Virtual Reality Technology

According to the advantages and characteristics of virtual reality technology, take the sudden venous he-morrhage in the operation of lower limb fracture as an example, this paper discusses the innovative application of virtual reality technology in surgery emergency training. Firstly, based on the theory of virtual reality technology and its application status in the medical field, by analyzing the risk factors in orthopaedic surgery and the defects of traditional surgical simulation training in emergency training, proposing the necessity of applying virtual reality technology to the field of surgical emergency training. Then, using the methods of user interview and literature research to establish surgery related medical databases. Finally, the virtual surgery emergency training system is developed based on Unreal Engine 4 software, and designing innovative wearable interactive devices. The application of virtual reality technology in emergency training of lower limb fracture surgery is a new research direction. The system of surgery emergency training based on virtual reality technology can not only realize the traditional operation simulation training, but also realize the emergency response training in operation. It can improve the operation skills and emergency response ability of doctors in operation. It solves the problem that traditional surgical training is difficult to achieve emergency response training, and has the characteristics of simple operation, low cost and strong experience.
