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.
1. A surgical instrument, comprising: a cartridge supporting assembly configured to operably support a staple cartridge therein, said cartridge supporting assembly having at least one elongated slot therein wherein each said slot comprises at least one wall having a series of detents formed as notch
1. A surgical instrument, comprising: a cartridge supporting assembly configured to operably support a staple cartridge therein, said cartridge supporting assembly having at least one elongated slot therein wherein each said slot comprises at least one wall having a series of detents formed as notches therein to define a plurality of closed positions; andan anvil having at least one mounting portion configured to facilitate selective movement between an open position and the closed positions, wherein each said mounting portion engages at least one detent of said series of detents to define one closed position of said closed positions, wherein at least one of said mounting portions corresponds to one said series of detents and is configured for engagement with any detent therein to automatically adjust a tissue clamping space between said anvil and said cartridge supporting assembly in response to a thickness of tissue clamped between a cartridge supported in said cartridge supporting assembly and said anvil. 2. The surgical instrument of claim 1 wherein said anvil has a proximal end that is pivotally coupled to a proximal end of said cartridge supporting assembly. 3. The surgical instrument of claim 2 wherein each said mounting portion comprises a trunnion wherein each said trunnion corresponds to a corresponding one of said at least one series of detents. 4. The surgical instrument of claim 3 further comprising a pawl formed on each said trunnion. 5. The surgical instrument of claim 4 wherein each said series of detents comprises a series of substantially V-shaped notches and wherein each said pawl has a point formed thereon adapted to be seatingly received within any one of said V-shaped notches in said corresponding series of V-shaped notches. 6. The surgical instrument of claim 4 further comprising a biasing member engaging a portion of said anvil such that each said pawl is biased into seating engagement with a corresponding first detent when no tissue is received between said anvil and said cartridge supporting assembly. 7. The surgical instrument of claim 1 wherein said anvil has a plurality of staple forming pockets therein and wherein said staple forming pockets are axially aligned with corresponding staples in the staple cartridge supported within said cartridge supporting assembly when said at least one mounting portion of said anvil is in seated engagement with any one of said detents formed in said cartridge supporting assembly. 8. The surgical instrument of claim 1 wherein said anvil further has an opening tab formed thereon for selective engagement by a closure tube assembly mounted adjacent said anvil and configured for selective engagement therewith. 9. A method for processing an instrument for surgery, said method comprising: obtaining said surgical instrument of claim 1;sterilizing said surgical instrument; andstoring said instrument in a sterile container. 10. 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, said elongate channel having at least one elongated slot therein, wherein each said slot comprises at least one wall and wherein said at least one wall has at least one series of detents formed as notches therein to define a plurality of closed positions;a selectively actuatable closure tube assembly movably received on said elongate spine assembly; andan anvil movably coupled to said elongate channel and configured to receive opening and closing motions from said selectively actuatable closure tube assembly, said anvil having at least one mounting portion configured to facilitate selective movement between an open position and the closed positions, wherein each said mounting portion engages at least one detent of said series of detents to define one closed position of said closed positions, wherein each said mounting portion corresponds to one said series of detents in said elongate channel and is configured to seatingly engage any one of said detents therein to automatically adjust a tissue clamping space between said anvil and a cartridge supported in said elongate channel in response to a thickness of tissue clamped between the cartridge supported in said elongate channel and said anvil and application of a closing motion to said anvil. 11. The surgical instrument of claim 10 wherein said anvil is pivotally coupled to said elongate channel by a pair of trunnions, each said trunnion corresponding to one of said at least one series of detents. 12. The surgical instrument of claim 11 wherein said portion of said anvil corresponding to said series of detents comprises a pawl formed on each said trunnion. 13. The surgical instrument of claim 12 further comprising a biasing member engaging a portion of said anvil such that each said pawl is biased into engagement with a corresponding first detent when no tissue is received between said anvil and said elongate channel. 14. The surgical instrument of claim 10 wherein said anvil has a plurality of staple forming pockets therein and wherein said staple forming pockets are axially aligned with corresponding staples in the staple cartridge supported within said elongate channel when said at least one said mounting portion is in seated engagement with any one of said corresponding detents in said elongate channel.
