Abstract
A surgical instrument includes a body, a shaft assembly rotatable relative to the body, and an end effector at a distal end of the shaft assembly and having an RF electrode operable to seal tissue with RF energy. An electrical contact assembly is arranged proximally of the end effector and is configured to electrically couple the RF electrode with an RF energy source. The electrical contact assembly includes a first electrical contact secured to the body and a second electrical contact secured to the shaft assembly. The first contact is configured to electrically couple with the RF energy source. The second contact is electrically coupled with the RF electrode and the first contact, and is configured to rotate with the shaft assembly relative to the first contact. The first and second electrical contacts are configured to remain electrically coupled throughout rotation of the shaft assembly relative to the body.
