doi:10.16182/j.issn1004731x.joss.18-VR0707

Abstract

Abstract: Virtual surgery simulation provides new means for medical surgery training with realism and immersion. A virtual surgery simulation of internal fixation for compression fractures is designed and implemented. By constructing 3D surgical scene, making deformation animation, adopting multi-level colliders combination and switching method for collision detection, and designing a multi-factors force feedback model to compute the tactile force and mapping the values to the different levels of vibration intensity of the HTC handle, combining with voice guidance and UI visual feedback, a visual, audible and tactile multi-channel surgical experience can be obtained. The system provides a guiding training module and an evaluation module. A variety of indicators, such as surgical procedures, the time spent and correctness of surgical operation, can be evaluated to standardize the user's operational procedures and improve proficiency of correct operation.

Key words: virtual surgery simulation, collision detection, force feedback, HTC Vive
