Expanding parallel jaw device for use with an electromechanical driver device
First Claim
1. A fastening and cutting device for cutting and closing a section of tubular tissue, comprising:
- a first jaw;
a second jaw disposed in parallel and opposed correspondence with the first jaw;
a vertical driver means coupled to said first jaw, which driver means causes the first jaw to linearly travel along an axis perpendicular to the axis of parallel correspondence of the first and second jaw, such that the first jaw may separate from the second jaw when the driver means is biased for opening of the jaws, and to close toward the second jaw when the driver means is biased for closing of the jaws; and
a cutting and stapling means disposed within the second jaw and coupled with a horizontal driver means for cutting and stapling a section of tissue disposed between the first and second jaws once the first jaw has been closed onto the second jaw.

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.

5. A fastening and cutting attachment for use with an electromechanical driver device for cutting and closing a section of tubular tissue, comprising:
-
a first jaw;
a second jaw disposed in parallel and opposed correspondence with the first jaw;
a vertical driving mechanism means coupled to said first jaw, said driving mechanism being actionably coupleable to the electromechanical driver device, which driver means causes the first jaw to linearly travel along an axis perpendicular to the axis of parallel correspondence of the first and second jaw, such that the first jaw may separate from the second jaw when the driver means is biased for opening of the jaws, and to close toward the second jaw when the driver means is biased for closing of the jaws. - View Dependent Claims (6, 7, 8)
