Abstract
A robotic surgical tool includes a handle providing a first drive input and a second drive input, an elongate shaft extendable through the handle and having an end effector arranged at a distal end thereof, and a rack extending along a portion of the shaft and operatively coupled to a knife located at the end effector. Actuation of the first drive input transitions the rack between a locked configuration, where the rack is locked to the shaft, and a released configuration, where the rack is released from the shaft. Actuation of the second drive input with the rack in the locked configuration drives the rack and causes z-axis translation of the shaft through the handle. Actuation of the second drive input with the rack in the released configuration drives the rack relative to the shaft and thereby advances or retracts the knife at the end effector.
