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