    • A surgical instrument positioning system includes articulating arms for coarse adjustment and a micro manipulator connectable to the articulating arms for fine adjustment. The micro manipulator selectively holds the surgical instrument and is operable to adjust the position of the surgical instrument. The micro manipulator includes two adjustment assemblies for providing linear adjustment and two adjustment assemblies for providing rotational adjustment. Features of the system also provide for control of the amount of free movement or play within the micro manipulator. Also a stop feature works in conjunction with the adjustment assemblies to maintain the tip of the instrument at an intersection of the two rotational axes facilitating rotational adjustment of the micro manipulator without linear displacement of the instrument tip.
    • 手术器械定位系统包括用于粗调的关节臂和可连接到关节臂的微操纵器以进行微调。 微操纵器选择性地保持外科器械,并且可操作以调节外科器械的位置。 微操纵器包括用于提供线性调节的两个调节组件和用于提供旋转调节的两个调节组件。 该系统的特征还提供了对微机械手内的自由运动或播放量的控制。 此外,停止特征与调节组件一起工作,以将仪器的尖端保持在两个旋转轴线的交叉点处,便于微操作器的旋转调节,而不会使仪器尖端发生线性位移。
