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.

moving a first jaw relative to a second jaw from an open position to a closed position to secure the section of tissue between the first jaw and the second jaw;
maintaining a parallel relationship between the first jaw and the second jaw between the open position and the closed position;
alerting an operator after the section of tissue is secured in the moving step; and
selectively driving a blade to cut the tissue and to drive a linear array of fasteners through the section of tissue, the blade and fasteners driven independently of the moving step and after the alerting step. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
