摘　　要：针对人工耳蜗植入训练与机器人植入实验所需,提出一种可扩展鼓阶模型设计方法。将耳蜗中心线数学模型作为鼓阶模型通道中心曲线,结合临床解剖学数据,将鼓阶截面轮廓近似为椭圆。沿中心曲线放置截面轮廓,调整角度确定轮廓在三维空间内的位置和方向并使中心曲线穿过其中心,将数据导入Matlab生成三维鼓阶数学模型,该模型可通过设置不同比例系数进行扩展。在SolidWorks中生成虚拟鼓阶模型,并通过3D打印制备2:1比例全透明鼓阶模型以替代标本进行实验。For cochlear implant training and robotic cochlear implant experiments,the design method of scalable scala tympani model was proposed.The mathematical model of the cochlea was used as the central curve of scala tympani channel.Referring to the clinical anatomy data,the contour of the scala tympani cross-section was approximated as an ellipse.The profile was placed along the central curve,and the angle was adjusted to determine the position and orientation of the profile in three dimensions such that the central curve passes through its center.The data was imported into Matlab to generate a three-dimensional mathematical model of scala tympani,which can be expanded by setting different scale factors.The virtual scala tympani model was generated in SolidWorks,and the 2:1 fully transparent scala tympani model were fabricated by 3D printing to replace the specimen for experiment.
