发明名称 TORQUE SENSING IN A SURGICAL ROBOTIC WRIST
摘要 A surgical robotic component comprising an articulated terminal portion, the terminal portion comprising: a distal segment having an attachment connected thereto, an intermediate segment, and a basal segment whereby the terminal portion is attached to the remainder of the surgical robotic component. The terminal portion further comprises a first articulation between the distal segment and the intermediate segment, the first articulation permitting relative rotation of the distal segment and the intermediate segment about a first axis, and a second articulation between the intermediate segment and the basal segment, the second articulation permitting relative rotation of the intermediate segment and the basal segment about a second axis. The intermediate segment comprises: a third articulation permitting relative rotation of the distal segment and the basal segment about third and fourth axes, a first torque sensor configured to sense torque about the third axis, and a second torque sensor configured to sense torque about the fourth axis. The first, second and third articulations are arranged such that in at least one configuration of the third articulation the first and second axes are parallel and the third and fourth axes are transverse to the first axis.
