摘　　要：背景:采用以计算机为核心的各种技术,将针灸专家正确有效的针刺方法,生成逼真的视觉、听觉、触觉一体化的计算机虚拟环境进行模拟针刺,能够极大增强操作者的真实感,减少临床针刺意外的发生。目的:构建虚拟肾俞穴针刺力反馈仿真系统。方法:通过力反馈设备,录取针灸名师的肾俞穴针刺手法,融入数字化虚拟人体。运用虚拟现实技术,在融合了肾俞穴信息的三维数字人体上,根据肾俞穴下各组织的物理特性,分析针刺过程中针体与组织的相互作用力,建立力学模型模拟针体受力,并通过力反馈设备真实地传递给操作者。结果与结论:初步实现了肾俞穴虚拟针刺力反馈仿真,使可视化的针灸虚拟人具有可现场模拟肾俞穴进针的触觉再现。肾俞穴针刺力反馈研究,为融合视觉、触觉和力反馈信息一体化的虚拟针刺作了初步探索,为针刺教学提供了一种动态的一对一仿真手段。BACKGROUND： The correct and effective acupuncture manipulation of famous doctors are used to generate the realistic visual, auditory and tactile integrated computer virtual environments for acupuncture simulation based on the various techniques with the core of computer, which can greatly enhance the realism of the operator, and reduce the clinical acupuncture accidents. OBJECTIVE： To establish the virtual Shenshu acupuncture force feedback simulation system. METHODS： Based on the force feedback device, the Shenyu manipulations from the famous acupuncturists were collected and integrated into the digital virtual body. On the three-dimensional digital human body integrated with information of Shenshu, the interaction force of needle body and tissues during the acupuncture process was analyzed with the virtual reality technology according to physical characteristics of the tissues within Shenshu, in order to establish the mechanical model to simulate needle body force, and to transmit truly to the operator by the force feedback device. RESUTLS AND CONCLUSION： Shenshu virtual acupuncture force feedback simulation was preliminary established, and the sense of touch could be reproduced lively during mimic the acupuncture of Shenshu on the visualized virtual acupuncture human. Shenyu acupuncture force feedback researches have provided a preliminary exploration for virtual acupuncture that integrated with the information of visual, tactile and force feedback, and also provided a dynamic one-on-one simulation means for acupuncture teaching.
