摘要:
A surgical instrument that includes an elongated shaft that defines defining a central axis. The elongated shaft may have a distal end portion that is configured to operably support a circular staple cartridge therein. A tissue acquisition shaft may be axially movable within the elongated shaft such that a distal end portion of the tissue acquisition shaft may be distally advanced beyond the distal end portion of the elongated shaft. At least one tissue acquisition member may be pivotally attached to the distal end portion of the tissue acquisition shaft such that at least one tissue acquisition member is selectively pivotable about a corresponding acquisition axis that is substantially parallel to the central axis from a retracted position to deployed positions upon application of a deployment motion thereto. Various embodiments include an annular cutting member that is supported by the distal end of the elongated shaft for selective axial travel relative thereto.
