Abstract
A surgical tool includes a drive housing having an elongate shaft extending therefrom, an end effector operatively coupled to a distal end of the shaft, and a drive input rotatably mounted to the drive housing and having an input shaft extending therefrom. An upper capstan assembly is rotatably mounted to the input shaft and has a first drive cable coupled thereto and extending to the end effector, and a lower capstan assembly is rotatably mounted to the input shaft and has a second drive cable coupled thereto and extending to the end effector. A compliant member is operatively coupled to and extends between the upper and lower capstan assemblies to provide a constant opposing torsional load on the upper and lower capstan assemblies and thereby remove slack in the first and second drive cables as the input shaft rotates.
