Surgical instrument with an anvil that is selectively movable about a discrete non-movable axis relative to a staple cartridge
First Claim
1. A surgical instrument, comprising:
- an elongate channel configured to operably support a surgical staple cartridge therein;
an anvil pivotally coupled to a proximal end of the elongate channel, the anvil being pivotable about a discrete, non-movable anvil axis defined by said elongate channel;
a firing member configured for axial travel within the elongate channel in response to an application of firing motions thereto, the firing member being configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel; and
a closure member configured to move the anvil between an open position and closed positions relative to the elongate channel upon application of closure motions to the closure member.

Abstract
A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.

16. A surgical instrument, comprising:
-
an elongate channel; a surgical staple cartridge operably supported in said elongate channel, the surgical staple cartridge operably supporting a plurality of surgical staples therein; a firing member operably supported for axial travel through the surgical staple cartridge to eject the surgical staples from the surgical staple cartridge; an anvil including an anvil forming surface configured to form the surgical staples ejected from the surgical staple cartridge, wherein the firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel; means for moving the firing member through the surgical staple cartridge; means for mounting a proximal end of the anvil to the elongate channel such that the anvil is selectively pivotable relative to the elongate channel without the proximal end of the anvil moving relative to the elongate channel; and means for pivoting a distal end of the anvil toward the elongate channel, the means for pivoting being independently operable from the means for moving the firing member. - View Dependent Claims (17)
