1. A surgical instrument, comprising:

  • an elastic spine assembly comprising a proximal spine portion and a distal spine portion that is elastically coupled to said proximal spine portion for axial movement relative thereto between a neutral position and an elongated position;

    a first jaw attached to said distal spine portion;

    a second jaw movably supported relative to said first jaw for selective movement between open and closed positions relative to said first jaw;

    a closure system configured to apply a closure motion to said second jaw and to move said distal spine portion from said neutral position to said elongated position upon actuation thereof; and

    a firing system configured to axially advance a firing member from a starting to an ending position within said first jaw upon actuation thereof and to enable said distal spine portion to return to said neutral position to thereby increase said closure motion applied to said second jaw.
