Abstract
A surgical instrument includes a handle, and an elongated shaft extending from the handle. An end effector extending from the elongated shaft is in communication with a source of electrosurgical energy and defines an end effector axis. A roll joint couples the end effector to the elongated shaft and includes a first tubular structure extending distally from the elongated shaft and a second tubular structure rotatably coupled to the first tubular structure. The second tubular structure supports the end effector such that the end effector is rotatable about the end effector axis. A cable wrap volume may be disposed within one of the first and second tubular structures, and a conductor for supplying the end effector with electrosurgical energy is coiled about the end effector axis within the cable wrap volume such that rotation of the end effector about the end effector axis in a first direction unwinds the conductor.
