At present, VR (Virtual Reality) technology has different degrees of application in various industries. In the field of medical education, it is a new choice for doctors to learn. Doctors only need to wear VR glasses to fully experience the feeling of being in the operating room. It allows the doctor to fully understand all aspects of the operation, and learn the surgical skills from the first perspective.
In addition to visual learning, virtual reality technology combined with computer technology to establish a surgical simulation training system with real-time force feedback seems to be able to alleviate the bottleneck faced by current medicine to a certain extent. For example, anatomy teaching with VR greatly alleviates the shortage of corpse specimens in medical education.
"The system we developed is aimed at the situation of orthopedic surgery training system for the orthopedic surgeons in the international and domestic markets, in order to solve the problem of orthopedic surgery training." The Human-Computer Interaction Center of Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences Director Wang Qiong told reporters during an interview.
Meet the needs of surgical training
According to reports, the orthopedic surgery training system is based on pedicle screw surgery. It provides three-dimensional interactive scene simulation of different kinds of surgical tools on the spine. It mainly simulates round drill bone drilling, long drill drilling and nailing. These types of pedicle screw surgery have higher risk and the most training operation.
“We built a virtual environment with dynamic feedback and visual changes, and connected with human-computer interaction feedback. It modeled the control force generated by the interaction between the surgical tool and the bone, and simulated the visual changes after the bone was drilled. And through the VR glasses and force feedback equipment feedback to the user, the simulated doctor holding the drill bit to drill the real scene of the bone, which can achieve hand-eye coordination training." Wang Qiong said.
In the system, the Wang Qiong team adopted the data structure of the fusion data and the surface data, which can not only meet the 100Hz collision detection refresh rate between the 3D surgical tool and the skeleton model under the condition that the bone topology changes frequently, but also can be accurate. The ground surface of the ground bone after reconstruction is reconstructed, and the interactive feedback force model of the surgical tool based on the grinding principle is established. Through the acceleration of the GPU hardware, the refresh rate of the force sense can be guaranteed above 1000 Hz, avoiding the visual and tactile interaction scene. distortion.
This project can provide doctors with pedicle screw surgery training to provide a virtual three-dimensional scene with real-time force feedback, which solves the problem of lack of surgical training opportunities for clinical orthopedic surgeons.
Because different computer programs can be used to create a new interactive environment that satisfies different surgical training situations. "The system can set the difficulty of surgery. When starting training, the system gives a fixed position of the nail and the direction of the drill. After the advancement, all the preset information is deleted. The trainer judges the condition and the position of the drill bit to increase the difficulty. This training method is more effective." Wang Qiong said.
Different ways of change provide fine, effective and repetitive training on the one hand, which not only saves economic costs, but also achieves advanced training that traditional training can't.
