SURGICAL STAPLING DEVICE WITH LOCKOUT SYSTEM FOR PREVENTING ACTUATION IN THE ABSENCE OF AN INSTALLED STAPLE CARTRIDGE
First Claim
1. A surgical stapling instrument comprising:
- an end effector comprising;
an elongate channel configured to operably support a surgical staple cartridge therein; and
an anvil movably supported on the elongate channel between an open position and closed positions in response to an application of opening and closing motions applied thereto; and
an anvil lock member cooperating with the anvil to retain the anvil in an open position when a staple cartridge has not been installed in the elongate channel and prevent the anvil from moving to a closed position until the staple cartridge has been seated within the elongate channel.

Abstract
Surgical stapling instruments surgical stapling cartridges are disclosed. At least one embodiment includes an end effector that has an elongate channel that is configured to operably support a surgical staple cartridge therein and an anvil that is movably supported on the elongate channel between an open position and closed positions in response to an application of opening and closing motions applied thereto. An anvil lock member cooperates with the anvil to retain the anvil in an open position when a staple cartridge has not been installed in the elongate channel and prevent the anvil from moving to a closed position until the staple cartridge has been seated within the elongate channel. Surgical staple cartridges are configured to move the anvil from an open position to an actuatable position when the cartridge has been installed in the end effector.

11. A surgical stapling instrument comprising:
-
a handle; an elongate shaft assembly operably coupled to the handle; a closure system operably supported by the handle for generating closing and opening motions in response to actuation of a closure trigger operably supported by the handle; an elongate channel coupled to the elongate shaft assembly; an anvil including an anvil mounting portion movably supported on the elongate channel between an open position and closed positions in response to applications of opening and closing motions transmitted thereto through the elongate shaft assembly; an anvil lock member operably supported by the elongate shaft assembly for movable engagement with the anvil mounting portion; and a surgical staple cartridge configured to be seated within the elongate channel and cooperating with the anvil mounting portion such that; when the surgical staple cartridge has not been seated within the elongate channel, the anvil lock member cooperates with the anvil mounting portion to retain the anvil in the open position; and when the surgical staple cartridge is seated within the elongate channel, the staple cartridge moves the anvil mounting portion to a position wherein the anvil may be closed upon application of the closure motions thereto. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

- 19. A surgical staple cartridge for use with a surgical stapling instrument including an end effector with an anvil that is supported in an open position until moved to an actuatable position wherein the anvil is movable to closed positions in response to a closing motion applied thereto by a closure system, the surgical staple cartridge comprising a cartridge body sized to be removably seated within a portion of the end effector such that a portion of the cartridge body contacts the anvil and moves the anvil from the open position to the actuatable position when seated within the end effector.
