摘要:
A robotic surgical instrument comprising a shaft and end effector element connected by an articulation. The articulation comprises a first joint driveable by a first pair of driving elements. The first joint permits the end effector element to rotate about a first axis transverse to a longitudinal axis of the shaft, the rotation of the end effector element about the first axis bounded by an extreme rotation angle relative to the longitudinal axis. A second joint is driveable by a second pair of driving elements. A pulley arrangement constrains the second pair of driving elements, and comprises a first set of pulleys rotatable about the first axis, and a second set of pulleys located relative to the first set of pulleys such that at the extreme rotation angle the second pair of driving elements is retained in contact with both the first and second sets of pulleys.
