A surgical device includes a tool assembly and a handle assembly. The tool assembly includes a distal portion including a plurality of staples and an anvil assembly movable relative to the distal portion from an open position to a clamped position. The handle assembly includes 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, and a controller. The force sensor is configured to sense a change in resistance indicating a force imparted on compressed tissue and on the approximation mechanism. The controller is configured to receive a signal indicative of a force measured by the force sensor and provide an indication of the sensed force.
A surgical device comprising:
A method for providing an indication of force for a surgical device, the method comprising:
A force sensor configured to sense a change in resistance indicating a force imparted on an approximation mechanism, the force sensor comprising:
