摘要： A force transmission mechanism for a teleoperated surgical instrument includes a drive pulley, a drive cable operably coupled with the drive pulley, a driven pulley operably coupled with the drive cable, and an actuation member operably coupled to the driven pulley. The actuation member is configured to transmit force to actuate an end effector of the surgical instrument. Rotational motion of the driven pulley causes translational movement of the actuation element to actuate the end effector. Methods relate to operating a force transmission mechanism.

摘要： An instrument comprises a plurality of elongate members having a proximal end and a distal end, a shaft, an actuation member extending through the shaft, and a tube member extending through the shaft and housing at least a portion of a length of the actuation members. An end effector is coupled to a distal end of, and a force transmission mechanism is coupled to a proximal region of, at least one of the plurality of elongate members. At least one of the plurality of elongate members comprises a first electrically conductive length portion, a second electrically conductive length portion, and an electrically insulative length portion between and connecting the first electrically conductive length portion and the second electrically conductive length portion. The electrically insulative length portion reduces a conductive length of the elongate member, thereby reducing a capacitive coupling effect in the instrument.
