摘要
文章介绍了一种应用于手术仿真中的实时力反馈技术。主要讨论了其实现的步骤过程和系统仿真结构,分析了其采用的质点-弹簧-阻尼器物理仿真模型,并描述了手术仿真中虚拟手术器械挤压软组织模型的面弹力和在软组织表面上的粘滞摩擦力的实现原理和方法,同时,为手术仿真中实时力反馈的实现和应用提出了一种解决的方案。
This paper introduces a kind of real-time force feedback technology used in virtual surgery simulation.It briefly discusses its actualization steps and its simulation structure,analyzes its mass-spring-damper simulation model,and describes the actualization theory and methodology of surface elasticity in virtual instruments extruding soft tissue models and of friction on soft tissue surface.Meanwhile,this paper provides a solution to the actualization and applica-tion of real-time force feedback in surgery simulation.
