An electromechanical surgical system is disclosed including a hand-held surgical instrument, an end effector configured to perform at least one function, and a shaft assembly arranged for selectively interconnecting the end effector and the surgical instrument. The shaft assembly includes a linkage having a proximal housing and a distal housing at least partially received within the proximal housing. The distal housing is rotatable relative to the proximal housing and configured to selectively interconnect the end effector to the shaft assembly. The shaft assembly further includes a wire extending through the linkage having a central portion disposed within an annular groove defined between the proximal and distal housings. The central portion of the wire is annularly wound within the annular groove to define a coil. The coil is configured to at least one of radially expand and contract upon rotation of the distal housing relative to the proximal housing.

A stretchable fabric signal path may include a conductive strand located between first and second outer fabric layers. The outer fabric layers may be formed from intertwined strands of elastic material. The conductive strand may have a wavy shape to accommodate stretching of the stretchable fabric signal path. First and second inner fabric layers may be located between the outer stretchable fabric layers. The inner fabric layers may be formed from intertwined strands of non-elastic material. The inner fabric layers may have strands that are intertwined with the outer fabric layers to serve as anchor points for maintaining the shape of the conductive strand as the stretchable fabric signal path expands and contracts. The outer fabric layers and inner fabric layers may be woven. The conductive strand may convey electrical signals such as audio signals, power signals, data signals, or other suitable signals.
