Abstract
A surgical tool assembly that includes an axially movable closure member and an axially movable firing member that is movable between an unfired position and a fired position. The tool assembly includes a second jaw that has a mounting portion and mounting walls that are movably mounted to a first jaw. The mounting portion defines a cam area that is configured for engagement by the movable closure member to move the second jaw from an open position to a closed position. The mounting walls define an open-topped parking area for accommodating the firing member therein when in the unfired position. A protective cap member is attached to the mounting walls such that it covers at least a portion of the open topped parking area.
