In accordance with an exemplary embodiment, a surgical instrument comprises a shaft and an actuation member extending through a bore of the shaft and operably coupled to an end effector. A sleeve is disposed around the actuation member and within the bore of the shaft. A flux conduit configured to transmit a surgical flux to the end effector is at least partially received within a negative feature of the sleeve. In accordance with another exemplary embodiment, a surgical instrument comprises a shaft, a wrist mechanism coupling an end effector to the shaft, and an actuation member operably coupled to the end effector. A sleeve surrounds the actuation member and has a straight passage. A flux conduit operably coupled to the end effector is received within the straight passage. A portion of the flux conduit is slack in a region of the shaft through which the sleeve does not extend.
