    Abstract: A surgical tool includes a drive housing having an input shaft and a drive cable capstan arranged therein. The input shaft includes a drive gear and the drive cable capstan including a driven gear intermeshed with the drive gear such that rotation of the input shaft rotates the drive cable capstan. An elongate shaft extends from the drive housing, and an end effector is operatively coupled to a distal end of the elongate shaft. A drive cable is received within a pulley track defined on the drive cable capstan and extends only partially around a circumference of the drive cable capstan. The drive cable is fed directly into the elongate shaft from the pulley track and extends to the end effector.
