Surgical stapling device with firing indicator of unitary construction

A surgical stapling device comprising:

• a handle assembly including a body portion defining a grip, a rotation knob and an indicator;
• an elongated body portion extending distally from the handle assembly;
• an end effector supported on a distal end of the elongated body portion, the end effector including a cartridge assembly and an anvil assembly;
• an approximation assembly including a drive screw movably supported within the handle assembly and an anvil retainer operably connected to the drive screw, the anvil retainer being configured to support the anvil assembly and the drive screw being operably engaged with the rotation knob such that actuation of the rotation knob effects movement of the anvil assembly in relation to the cartridge assembly between spaced and approximated positions;
• and
• a screw stop secured to the drive screw;
• wherein the indicator is of unitary construction and includes an indicator body portion, a pivot support member, a resilient lever and an anchor, the pivot support member having a first end secured to the indicator body portion and a second end secured to a first end of the resilient lever, the resilient lever having a second end secured to the anchor, the pivot support member being pivotally secured to the body portion of the handle assembly and the anchor being fixed within the body portion of the handle assembly such that pivotal movement of the indicator body from a first position to a second position effects movement of the resilient lever from a relaxed configuration to a stressed configuration, wherein in the stressed configuration, the resilient lever urges the indicator body portion towards the first position.
