  • Patent number: 8568425
    Abstract: A surgical apparatus for performance of a surgical procedure on body tissue is provided and includes a housing, an elongate tubular member, a drive assembly, an electrical coupling component, and an electrical wire. The elongate tubular member is at least partially supported by the housing and defines a center lumen and a longitudinal axis. The drive assembly extends from the housing into the center lumen of the elongate tubular member. The electrical coupling component is located about the drive assembly. The electrical wire extends from within the housing into the elongate tubular member. The electrical wire is wrapped about the electrical coupling component, which allows the elongate tubular member to rotate about the longitudinal axis while allowing the electrical wire to be fixed within the housing and the elongate tubular member.
