Tool assembly for a surgical stapling device
First Claim
1. A stapling instrument having a tool assembly for use with a robotic surgical stapling device, the tool assembly comprising:
- an anvil and a cartridge assembly, the cartridge assembly having a plurality of fasteners, the anvil and cartridge assembly having a spaced position and an approximated position, the anvil and cartridge assembly defining a tissue gap in the approximated position;
a clamp member being movable to move the anvil and cartridge assembly to the approximated position;
means to eject the plurality of fasteners from the cartridge assembly into tissue;
a clamping member movably positioned in relation to the anvil and cartridge assembly to maintain the tissue gap, the clamping member engaging a cam surface of the tool assembly; and
a flexible cable connected to the clamping member, the flexible cable being longitudinally movable within the stapling instrument to move the clamping member longitudinally in relation to the anvil and the cartridge assembly to maintain the tissue gap.

Abstract
A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.
