虚拟手术是培训医生的新兴的有效手段,在虚拟环境中利用视觉、听觉、触觉力觉多感知交互信息,学习和感知手术过程,其中触觉力觉是至关重要的和较难的技术,本文分析了触觉力觉技术在虚拟手术过程中的重要性以及国内外研究现状,对力学变形算法和力觉感知硬件设备的研制和应用进行了探讨。虚拟手术研究的进一步开展,将提高我国数字医学研究的水平。

The virtual operation is a available training measure, the process of operation will be learned in virtualenvironment by vision, sound and haptic feedback. The haptic feedback is an important and difficult technology, thesignificance and situation over the world is analysed, the algorithm of tissue deformation and haptic feedback devicedevelopment is discussed. The development of the virtual operation will improve the level of digital medicine studying.
