Patent attributes
The present invention includes a tool assembly with a first jaw movable in relation to a second jaw between a spaced position and an approximated position. An approximation member is movable in relation to the first jaw to effect movement of the first and second jaws from the spaced position to the approximated position. A cam channel is configured to approximate the distal ends of the first and second jaws prior to approximation of the proximal ends of the first and second jaws. An articulation and firing actuator includes a flexible band having first and second end portions, wherein movement of either the first or the second end portion of the band effects pivoting of the tool assembly, and movement of the both end portions of the band, simultaneously, effects movement of a dynamic clamping member to eject staples from a cartridge assembly.
