See full text

A surgical instrument includes an end effector including first and second jaw members movable relative to one another between a first, spaced-apart position and a second position proximate tissue. In the second position, the jaw members cooperate to grasp tissue therebetween. A first optical fiber is disposed within the first jaw member and is configured to provide a first signal, and a second optical fiber is disposed within the first jaw member and is configured to provide a second signal. A controller is coupled to the first and second fibers and is configured to determine the temperature and the strain of the first jaw member as a function of the first and second signals, respectively.
