A Robotic Surgical Instrument

Abstract: A robotic surgical instrument for performing a surgical procedure, the instrument comprising a shaft, an end effector comprising an electrical component and an articulation connecting the shaft to the end effector. The articulation permits the end effector to rotate relative to the shaft about a first axis. The robotic surgical instrument further comprises an electrical cable extending along the shaft. The electrical cable is configured to provide electrical current for the electrical component of the end effector. The robotic surgical instrument further comprises an electrical connector extending at least partially around a circumference surrounding the first axis. The electrical connector provides a sliding electrical connection between the electrical cable and the end effector, such that the end effector is permitted to rotate about the first axis independently of the electrical cable whilst the electrical connection between the electrical cable and the end effector is maintained.
