Abstract: 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.
