SURGICAL CUTTING AND STAPLING INSTRUMENT WITH SELF ADJUSTING ANVIL
First Claim
1. A surgical instrument, comprising:
- a cartridge supporting assembly configured to operably support a staple cartridge therein; and
an anvil coupled to said cartridge supporting assembly and being configured to interact therewith such that at least a mounting portion of said anvil can seatingly engage corresponding portions of said cartridge supporting assembly at any one of a discrete number of predetermined locations to adjust a tissue clamping space between said anvil and said cartridge supporting assembly in response to a thickness of tissue received between a cartridge supported in said cartridge supporting assembly and said anvil and application of a closing motion to said anvil.

Abstract
A surgical instrument for being endoscopically or laparoscopically inserted into a surgical site for simultaneous stapling and severing of tissue includes an elongate channel that is configured to operably support a staple cartridge therein. An anvil is coupled to the elongate channel and is configured to interact therewith such that at least a mounting portion of the anvil can seatingly engage corresponding portions of the elongate channel at any one of a discrete number of predetermined locations to adjust a tissue clamping space between the anvil and the elongate channel in response to a thickness of tissue received between the elongate channel and the anvil and application of a closing motion to the anvil.

12. A surgical instrument, comprising:
-
an elongate channel configured to operably support a staple cartridge therein; and an anvil movably coupled to said elongate channel and configured to interact with at least one series of pivot nests in said elongate channel to selectively adjust a tissue clamping space between said anvil and a staple cartridge supported within said elongate channel in response to a thickness of tissue received between said anvil and the staple cartridge and application of a closing motion to said anvil. - View Dependent Claims (13)

14. A surgical instrument, comprising:
-
a handle assembly; an elongate spine assembly coupled to said handle assembly; an elongate channel distally coupled to said elongate spine assembly and configured to support a staple cartridge therein; a selectively actuateable a closure tube assembly movably received on said elongate spine assembly; and an anvil movably coupled to said elongate channel and configured to receive opening and closing motions from said selectively actuatable closure tube assembly, said anvil further configured to seatingly engage corresponding portions of said elongate channel at any one of a discrete number of predetermined locations in response to a thickness of tissue clamped between said elongate channel and said anvil and application of a closing motion to said anvil. - View Dependent Claims (15, 16, 17, 18, 19)
