Abstract

An apparatus includes: (a) at least one platform configured to be positioned between opposing first and second jaws of an end effector of a surgical stapler, wherein the at least one platform is configured to transition between a first state and a second state; (b) at least one adjunct element positioned on the at least one platform; (c) at least one detector configured to detect a predetermined portion of the end effector; and (d) a driver configured to selectively transition the at least one platform from the first state to the second state in a direction toward at least one of the first or second jaws when the at least one detector detects the predetermined portion of the end effector for placing the at least one adjunct element in contact with a corresponding surface of the at least one of the first or second jaws.
