Surgical tools having a two degree-of-freedom wrist, wrist articulation by linked tension members, mechanisms for transmitting torque through an angle, and minimally invasive surgical tools incorporating these features are disclosed. An elongate intermediate wrist member is pivotally coupled with a distal end of an instrument shaft so as to rotate about a first axis transverse to the shaft, and an end effector body is pivotally coupled with the intermediate member so as to rotate about a second axis that is transverse to the first axis. Linked tension members interact with attachment features to articulate the wrist. A torque-transmitting mechanism includes a coupling member, coupling pins, a drive shaft, and a driven shaft. The drive shaft is coupled with the driven shaft so as to control the relative orientations of the drive shaft, the coupling member, and the driven shaft.

A clamping device comprising: a distal end side stationary blocks which are provided on a side of a distal end of a workpiece retaining base, and in which stationary tilt faces tilting downwardly to a central direction of the workpiece are formed; a proximal end side stationary blocks which are provided on a side of a proximal end of the workpiece retaining base, and in which upward stationary tilt faces tilting downward toward the central direction of the workpiece are formed; and a movable block which is arranged at a position proximal to the proximal end side stationary blocks, and is capable of advancing to or retracting from a side of the distal end side stationary blocks with the workpiece being held between the blocks, and in which a downward movable tilt face tilting upwardly toward the central direction of the workpiece is formed.

A multi-user medical robotic system for collaboration or training in minimally invasive surgical procedures includes first and second master input devices, a first slave robotic mechanism, and at least one processor configured to generate a first slave command for the first slave robotic mechanism by switchably using one or both of a first command indicative of manipulation of the first master input device by a first user and a second command indicative of manipulation of the second master input device by a second user. To facilitate the collaboration or training, both first and second users communicate with each other through an audio system and see the minimally invasive surgery site on first and second displays respectively viewable by the first and second users.
