Patent Images
1. A surgical stapling device comprising:
- a handle portion;
a body portion extending distally from the handle portion;
a head portion including an anvil and a cartridge, the cartridge being movable in relation to the anvil from an open position to a closed position;
an approximation mechanism operatively connected to the cartridge and being actuable to move the cartridge from the open position to the closed position;
an alignment pin assembly including a pusher operatively associated with the approximation mechanism, the pusher being movable in response to actuation of the approximation mechanism; and
a manual engagement member located remotely of the head portion and being operatively associated with the alignment pin assembly, the manual engagement member being movable to manually move the pusher from a retracted position to an advanced position prior to actuation of the approximation mechanism.

Abstract
A surgical stapling device for applying an array of surgical staples to tissue is provided. The stapling device includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly. A single trigger is operable to effect approximation and firing of the device. The device also includes an alignment pin assembly which can be selectively manually or automatically advanced. The anvil assembly includes a stiffener plate which allows the device to have a reduced head portion profile.

14. A surgical stapling device comprising:
-
a handle portion;
a body portion extending from the handle portion;
a head portion including an anvil and a cartridge, the cartridge being movable from a first position to a second position, wherein the cartridge includes an alignment pin movable within the cartridge;
an approximation mechanism operatively connected to the cartridge, wherein actuation of the approximation mechanism repositions the cartridge from the first position to the second position;
a pusher movable from a retracted position to an advanced position to move the alignment pin; and
a manual engagement member located remotely of the head portion, the manual engagement member operatively associated with the pusher, wherein the pusher is movable in response to actuation of the manual engagement member and actuation of the approximation mechanism. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A surgical stapling device comprising:
-
a handle portion;
a body portion extending from the handle portion;
a head portion including an anvil and a cartridge, the cartridge being movable in relation to the anvil from an open position to a closed position;
an approximation mechanism operatively coupled to the cartridge, wherein actuation of the approximation mechanism repositions the cartridge from the open position to the closed position;
a pusher being movable in response to the approximation mechanism;
means for manually moving the pusher from the retracted position to the advanced position, the means located remotely from the head portion; and
activation means for moving the pusher from the retracted position to the advanced position in response to actuation of the approximation mechanism. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
