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, a drive input rotatably mounted to the drive housing and having an input shaft extending therefrom, an upper capstan assembly rotatably mounted to the input shaft and having a first drive cable coupled thereto and extending to the end effector, a lower capstan assembly rotatably mounted to the input shaft and having a second drive cable coupled thereto and extending to the end effector, and a compliant member mounted to the input shaft and arranged in-line and extending between the upper and lower capstan assemblies, the compliant member providing a constant opposing torsional load on the upper and lower capstan assemblies and thereby removing slack in the first and second drive cables as the input shaft rotates.
