  • Articulating surgical instrument
    Patent number: 11628028
    Abstract: A surgical instrument for use with a robotic manipulator includes an end effector assembly having one or two end effector members, each having a distal treatment end, a proximal end, and a tendon pass-through. Each end effector member is sandwiched between a corresponding pair of pulley members that, when assembled define an annular tendon pathway that is between the pulley members and that is aligned with the pass-through. For each end effector member, a tendon having a distal loop portion ends through the tendon pass-through, with its legs passing proximally from the pass-through, extending in opposite directions around the tendon pathway and proximally through the instrument's shaft.
