  • Driving arrangement for articulating a surgical instrument
    Patent number: 11129686
    Abstract: A robotic surgical instrument comprising a shaft, a first end effector element, an articulation connecting the first end effector element to a distal end of the shaft, the first end effector element being movable relative to the articulation, and a drive mechanism at a proximal end of the shaft. The drive mechanism comprises a first actuator connected to the first end effector element by a first pair of driving elements. The first pair of driving elements are configured such that a tension force applied by the first actuator to a first one of the first pair of driving elements causes the first end effector element to move relative to the articulation in a first motion direction, and the tension force applied to a second one of the first pair of driving elements causes the first end effector element to move relative to the articulation in a second motion direction.
