Abstract
A surgical tool for use with a robotic system includes an end effector comprising at least one component portion selectively movable between first and second positions and a shaft including an axially movable portion in operable communication with the at least one selectively movable component portion and a rotatably movable portion in operable engagement with the axially movable portion. An initial rotation of the rotatably movable portion causes the axially movable portion to move the selectively movable component portion from the first position into an intermediate position at a first rate. A subsequent rotation of the rotatably movable portion in a same direction causes the axially movable portion to move the selectively movable component portion from the intermediate position to the second position at a second rate different from the first rate.
