Abstract
A surgical tool includes a drive housing, a drive input rotatably mounted to a bottom of the drive housing, a capstan assembly arranged within the drive housing and operatively coupled to the drive input such that rotation of the drive input correspondingly actuates the capstan assembly, a longitudinally driven gear engageable with the drive gear, a drive rod coupled to the longitudinally driven gear and extending from the drive housing to an end effector of the surgical instrument and at least one biasing member mounted to the drive housing and operatively coupled to at least one of the capstan assembly and the longitudinally driven gear. The biasing member biases the longitudinally driven gear toward a proximal position with a constant force.
