摘要： A device for sensing the relative rotary position of first and second parts about a rotation axis, the device comprising a follower constrained to move on a first track fast with the first part and on a second track fast with the second part, the first track being linear and the second track comprising a plurality of circular arcs and at least one transition section connecting one of the circular arcs to another, the tracks being arranged so as to convert relative rotation of the parts into linear motion of the follower, wherein the second track is generally spiral, each circular arc is of constant radius about the rotation axis and the first track is perpendicular to the rotation axis.

摘要： A cooling structure and a method of cooling a surgical robot arm. The surgical robot arm extends from a proximal end attached to a base to a distal end attachable to a surgical instrument via a series of links interspersed by articulations. The cooling structure comprises a loop for circumscribing the surgical robot arm. The loop comprises a hollow interior for feeding cooling fluid through the loop, and a series of orifices directed towards the surgical robot arm for feeding cooling fluid from the loop towards the surgical robot arm. The cooling structure further comprises a feeder conduit attached to the loop for feeding cooling fluid from a cooling fluid source to the loop.
