1. A surgical device comprising:
a tool assembly including:
a distal portion including a plurality of staples; and
an anvil assembly being movable relative to the distal portion from an open position to a clamped position;
a handle assembly including:
an approximation mechanism coupled to the anvil assembly and configured to move the anvil assembly from the open position to the clamped position;
a force sensor disposed at a distal end of the surgical device, the force sensor configured to sense a change in electrical resistance indicating a compression force on tissue, wherein the force sensor includes:
a substantially circular substrate including a proximal side and a distal side;
a conductive trace disposed on the distal side of the substrate; and
a conductive material disposed on the conductive trace; and
a controller configured to:
receive a signal indicative of a force measured by the force sensor; and
provide an indication of the sensed force.
