First Claim
Patent Images
1. A surgical stapling device comprising:
- a frame having first and second ends;
a body portion defining a stationary handle, the body portion being secured to the first end of the frame;
a trigger pivotably secured to the body; and
a head portion including an anvil, assembly and a cartridge assembly, the anvil assembly being secured to the second end of the frame, the cartridge assembly and the anvil assembly being movable in relation to each other between spaced and approximated positions;
wherein the anvil assembly includes an anvil having a plurality of staple forming pockets and a stiffener plate, the anvil being configured to be fastened about the stiffener plate, the stiffener plate providing added strength to the anvil assembly to permit a reduction in size of the head portion.

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.

5. A surgical stapling device comprising:
-
a body having a stationary handle portion;
a trigger pivotably fastened to the body;
a head portion including an anvil assembly and a cartridge assembly, the anvil assembly and the cartridge assembly being movable in relation to each other from a spaced position to an approximated position;
an approximation mechanism operatively connected to the head portion, the approximation mechanism being actuable to move the anvil and cartridge assemblies in relation to each other between the spaced and approximated positions; and
an alignment pin assembly including an alignment pin having a tip, the alignment pin assembly being actuable to advance the alignment pin from a retracted position to an advanced position in which the alignment pin tip engages the anvil assembly;
wherein the alignment pin assembly is releasably coupled to the approximation mechanism such that the alignment pin assembly can be manually actuated independently of the approximation mechanism or automatically actuated in response to actuation of the approximation mechanism. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
