A surgical tool or applier for deploying an anastomotic ring comprises a handle connected to an elongate shaft that terminates in an anastomotic ring deployment mechanis m. The ring deployment mechanism is moveable from an unactuated position to an actuated position. In order to prevent tissue from becoming trapped in the ring deployment mechani sm during insertion or extraction of the tool, a plurality of panels are configured to enclose portions of the ring deployment mechanism during insertion and extraction, where the rin g deployment mechanism is in the unactuated position. The panels are moveable with the ri ng deployment mechanism to the actuated position, in which the ring deployment mechanism i s able to deploy the anastomotic ring.
