Abstract

An apparatus includes a platform, an adjunct material, and an engagement feature. The platform includes an upper support and a lower support. The adjunct material is positioned on the upper support or the lower support. The upper support is configured to move relative to the lower support to apply the adjunct material to a jaw of an end effector incorporated into a surgical stapler. The engagement feature is configured to interact with a predetermined portion of the end effector to permit movement of the upper support relative to the lower support and thereby apply the adjunct material to the jaw of the end effector. The engagement feature is further configured to inhibit movement of the upper support relative to the lower support when the engagement feature is disengaged from the predetermined portion of the end effector.
