Abstract:
A surgical stapling device includes a handle assembly that supports an audible indicator mechanism including a spring biased clicker. The spring biased clicker includes a pin that is received within a pin slot or cavity in the housing of a stationary handle of the handle assembly. The pin is movable through the cavity in response to actuation of the firing trigger assembly and unapproximation of the anvil assembly to guide movement of the clicker such that the clicker 1) provides an enhanced audible indication to a clinician that the firing stroke of a firing trigger has been completed, and 2) provides an enhanced indication to a clinician that the anvil assembly has been moved back to the unapproximated or spaced position after the firing stroke has been completed.
