Patent attributes
A method of operating an end effector, the end effector including opposing first and second jaws, a distal clevis defining an inner pulley and having a first axle that rotatably mounts the first and second jaws to the distal clevis, a proximal clevis having a second axle that rotatably mounts the distal clevis to the proximal clevis, a plurality of drive cables extending to the end effector, and a power axle cable mounted to the distal clevis at the inner pulley. The method further includes moving one or more of the plurality of drive cables and thereby causing the end effector to articulate about a first pivot axis extending through the first axle, and moving the power axle cable and thereby pivoting the end effector about a second pivot axis extending through the second axle and perpendicular to the first pivot axis.
