Abstract
Surgical instruments are disclosed. Various non-limiting embodiments may include an elongated shaft that has a distal end portion that is configured to operably support a circular staple cartridge therein. A tissue acquisition shaft may be rotatably supported within said elongated shaft and have a distal portion that protrudes distally 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 the tissue acquisition members are selectively pivotable from a retracted position to deployed positions upon application of a deployment motion thereto. A rotatable cutting member may be operably supported adjacent to the tissue acquisition member and being selectively rotatable about the central axis upon application of a cutting actuation motion thereto.
