Zusammenfassung:A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end component of a surgical instrument. The surgical instrument includes a chassis at a proximal end of the surgical instrument, drive components mounted in the chassis, a distal end component at a distal end of the surgical instrument, a flexible tensioning element coupled between a firstof the drive components and the distal end component, and a dynamic preload tensioner mounted in the chassis and coupled to a second of the drive components. The flexible tensioning element extends along a path. The dynamic preload tensioner is configured to be driven by the second of the drive components to be moved relative to the chassis and is positioned to change the path of the flexible tensioning element as the dynamic preload tensioner moves relative to the chassis. 一种外科手术系统包括用于张紧元件的动态预加载张力特征,其致动外科手术器械的远端部件。外科手术器械包括位于外科手术器械的近端的底架,安装在底架中的驱动部件,位于外科手术器械的远端的远端部件,耦接在驱动部件中的第一驱动部件和远端部件之间的柔性张紧元件,以及安装在底架中并且耦接到驱动部件中的第二驱
