摘要： A robotic surgical instrument comprising a shaft, an articulation attached to the distal end of the shaft, and a driving mechanism at the proximal end of the shaft. The articulation comprises a plurality of joints for articulating an end effector, the plurality of joints driveable by at least first and second pairs of driving elements. The driving mechanism comprises a pulley arrangement and a pulley drive. The pulley arrangement comprises first and second pulleys attached together such that their separation is fixed, wherein the first pair of driving elements is constrained to move around the first pulley, and the second pair of driving elements is constrained to move around the second pulley. The pulley drive is configured to linearly displace the pulley arrangement, such that a linear displacement in one direction away from the distal end of the shaft causes the first pair of driving elements to be tensioned and the second pair of driving elements to be de-tensioned, and a linear displacement in an opposing direction towards the distal end of the shaft causes the second pair of driving elements to be tensioned and the first pair of driving elements to be de-tensioned.

摘要： A robotic surgical instrument comprising a shaft, an articulated section and a drive mechanism. The articulated section extends from the shaft and terminates at its distal end in a tip. The tip has an attachment for an end effector. The drive mechanism drives the articulated section via flexible driving elements thereby altering the angular orientation of the tip relative to the shaft. The drive mechanism is controlled so as to always fully compress the articulated section along at least one extent by which the articulated section connects the tip and the shaft whilst driving the articulated section from any one configuration to any other configuration. The drive mechanism constrains movement of the articulated section so as to permit the tip to move with two degrees of rotational freedom and no degrees of translational freedom relative to the shaft.

摘要： A control system configured to control manipulation of a surgical instrument in response to manipulation of a remote surgeon input device, the surgical instrument comprising opposable first and second end effector elements connected to a shaft by an articulated coupling, the articulated coupling comprising a first joint driveable by a first pair of driving elements so as to permit the first end effector element to rotate, and a second joint driveable by a second pair of driving elements so as to permit the second end effector element to rotate, the control system configured to: detect a change of configuration of the surgeon input device to a gripping configuration at time t; respond to the change of configuration of the surgeon input device to the gripping configuration by commanding gripping forces to be applied to the first and second pairs of driving elements, so as to cause the first and second end effector elements to rotate in opposing rotational directions towards each other with a gripping closing force to a closed configuration; and if the first and second end effector elements are still in the closed configuration at time t+T, commanding a reduction in the force applied to the first and second pairs of driving elements, thereby causing the first and second end effector elements to subsequently be held in a further closed configuration with a reduced closing force.
