Summary:A robotic surgical tool includes an elongate shaft extendable through a handle that provides a drive input, an actuation system housed within the handle and operatively coupled to the drive input such that actuation of the drive input operates the actuation system, a rocker bar system arranged at a proximal end of the shaft and actuatable to articulate an end effector at a distal end of the shaft, and first and second drive cables extending along a portion of the shaft, each drive cable having a proximal end anchored to the shaft proximal to the handle and a distal end anchored to the shaft distal to the handle, wherein the drive cables are threaded through portions of the actuation and rocker bar systems such that operation of the actuation system acts on the drive cables and thereby actuates the rocker bar system to articulate the end effector.
