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.

The present disclosure relates generally to a surgical stapling instrument for applying surgical staples to body tissue. More particularly, the present disclosure relates to a surgical stapling instrument suitable with a firing indicator.
2. Background of Related Art
Various embodiments of the presently disclosed surgical stapling instrument are disclosed herein with reference to the drawings, wherein:
FIG. 1 is a perspective view of the presently disclosed surgical stapling instrument illustrated in an unapproximated position, in accordance with an embodiment of the present disclosure;
FIG. 2 is a perspective view of the surgical stapling instrument of FIG. 1 illustrated in an approximated unfired position;
Embodiments of the presently disclosed surgical stapling instrument will now be described in detail with reference to the drawings in which like reference numerals designate identical or corresponding elements in each of the several views.
Throughout this description, the term “proximal” will refer to the portion of the instrument closer to the operator and the term “distal” will refer to the portion of the instrument further from the operator.
FIGS. 1-3 illustrate one embodiment of the presently disclosed surgical stapling instrument shown generally as reference numeral 10. Briefly, surgical stapling instrument 10 includes a handle assembly 12, an elongated body portion 14 including a curved elongated outer tube 14a, and a head portion 16. Alternately, in some surgical procedures, e.g., the treatment of hemorrhoids, it is desirable to have a substantially straight body portion. The length, shape and/or the diameter of body portion 14 and head portion 16 may also be varied to suit a particular surgical procedure.
