Abstract:
1. A surgical apparatus for performance of a surgical procedure on body tissue, the surgical apparatus comprising: a housing; an elongate tubular member at least partially supported by the housing, the elongate tubular member defining a center lumen and a longitudinal axis; a drive assembly extending from the housing into the center lumen of the elongate tubular member; an electrical coupling component being located about the drive assembly; and an electrical wire extending from within the housing into the elongate tubular member, the electrical wire being wrapped about the electrical coupling component, the electrical coupling component allowing 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, wherein the electrical coupling component includes a fixed member and a rotatable member, the fixed member is prevented from both longitudinal and rotational movement by the housing, the rotatable member being rotatable with respect to both the fixed member and the housing, wherein the rotatable member includes a tubular spool, the tubular spool defines a helical groove to provide the electrical wire with a predefined path along the tubular spool.
