  • Patent number: 8317073
    Abstract: A surgical stapling instrument including a handle assembly, an elongated body portion extending distally from the handle assembly, and a head portion. The handle assembly includes a firing trigger and a firing indicator. The firing trigger is movable between a first non-actuated position and a second actuated position. The head portion is disposed adjacent a distal portion of the elongated body portion and includes an anvil assembly and a shell assembly. The anvil assembly is movable in relation to the shell assembly between spaced and approximated positions. Engagement structure of the firing trigger moves the firing indicator from a first position to a second position when the firing trigger is moved from its first non-actuated position toward its second actuated position.
