A forceps includes a housing defining a window and having an outer shaft extending therefrom. An end effector assembly disposed at a distal end of the outer shaft includes first and second jaw members including distal portions and proximal portions and movable between spaced-apart and approximated positions. An inner shaft is slidably disposed within the outer shaft such that, when the jaw members are disposed in the spaced-apart position, the inner shaft is disposed in a distal position. When the jaw members are moved to the approximated position, the proximal portions urge the inner shaft to a proximal position. An indicator member coupled to the inner shaft includes first and second indicators. The first indicator is visible through the window when the inner shaft is disposed in the distal position. The second indicator is visible through the window when the inner shaft is disposed in the proximal position.
