Abstract
Abstract A cutting and stapling device for use as an attachment to an electromechanical device driver comprises an upper jaw and a lower jaw which separate and close against one another in a continuously parallel alignment. The upper jaw includes a series of staple guides corresponding to one or more staples in a removable staple tray disposed within a lower jaw, whereby a blade and wedge having a threaded bore travel upon a matching threaded shaft in a channel disposed in the lower jaw below the staple tray, such that rotation of the threaded shaft causes movement of the wedge through the channel while a sloped surface of the wedge contacts the staples to push the staples against the staples guides, closing the staples.
