Abstract

The invention discloses a virtual dental implant surgery training system. The system comprises a computer, a VR head-mounted display device and a force feedback device. The computer is provided with atissue deformation unit, a surgical tool unit, a force feedback unit and a collision detection unit. The tissue deformation unit renders a three-dimensional oral model on the VR head-mounted displaydevice. The VR head-mounted display device and the force feedback device are interacted with a student. The collision detecting unit is used to detect the movement information of the force feedback device and send to the tissue deformation unit for processing. The tissue deformation unit sends force feedback information to the force feedback device through the force feedback unit, and the force feedback device generates force feedback based on the force feedback information. The system provides a realistic and immersive training environment, the student can carry out dental implant operation on a virtual model, understand an oral structure, and be familiar with the whole process of a dental implant surgery, and problems during a dental implant surgery process, and a dental implant surgerytraining effect is increased.

Description

technical field [0001] The present invention relates to the field of virtual reality applications, and more specifically, to a virtual implant surgery training system. Background technique [0002] At present, the virtual surgery simulation system is a typical application of virtual reality technology in the medical field. Virtual surgery is a surgical system that starts from medical image data, uses computer graphics to reconstruct a virtual human soft tissue model, simulates a virtual medical environment, and uses tactile interaction devices to interact with it. However, most of the research in this field is limited to the visualization stage of simulation, and the operation performed by doctors in the virtual environment is very different from the clinical environment due to the lack of tactile effects, or poor tactile effects. [0003] For a long time, implantology has been considered as the clinical course with the most abstract understanding, the most difficult to lea...
