6. A surgical fastener applier comprising:
a housing;
an elongated shaft extending distally of the housing and having a longitudinal axis;
a jaw mechanism including first jaw and a second jaw at a distal portion of the elongated member, at least the first jaw movable with respect to the second jaw to a clamping position to clamp tissue between the first and second jaws;
a manually actuated jaw clamping mechanism, the clamping mechanism including an elongated clamping member movable linearly from a distal position to a proximal position to move at least the first jaw toward the second jaw to clamp tissue;
one or both of a) a motor powered firing mechanism positioned within the housing, the firing mechanism movable between a first position and a second position, wherein movement to the second position effects firing of fasteners into the tissue clamped between the first and second jaws; and b) a motor powered articulation mechanism positioned within the housing, the articulation mechanism movable between a first position and second position to move the first and second jaws to a position angled with respect to the longitudinal axis of the elongated shaft, wherein the first and second jaws are articulable in a first direction with respect to the longitudinal axis and articulable in a second direction with respect to the longitudinal axis; and
a sensor for sensing clamping pressure of the first and second jaws on tissue, the sensor axially aligned with the elongated clamping member wherein proximal movement of the clamping member applies a force to the sensor.
