1. A device for cutting and fastening a section of tissue, comprising:
- a first jaw;
a second jaw in opposed correspondence with the first jaw and adapted to retain one or more fasteners, the first and second jaws being movable in a non-rotational manner relative to one another between an open position and a closed position;
a wedge, disposed in an axially translating relation at the second jaw, the wedge including a blade and a sloped surface, such that during the selective axial translation of the wedge, the blade transects the section of tissue, and the sloped surface drives the fasteners through the tissue and toward the first jaw, thereby fastening the section;
a first rotatable shaft for effecting the relative movement of the first and second jaws between the open position and the closed position; and
a second rotatable shaft for driving the wedge member, the second rotatable shaft being rotatable independently of the first rotatable shaft.

Abstract
A stapling device for use as an attachment to an electromechanical device driver comprises an upper jaw and a lower jaw, the upper jaw having staple guides corresponding to one or more staples in a removable staple tray disposed within a lower jaw, whereby a wedge having a threaded bore travels upon a matching threaded shaft in a channel disposed in the lower jaw behind 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.

15. A device for cutting and fastening a section of tissue, comprising:
-
a first jaw;
a second jaw in opposed correspondence with the first jaw and adapted to retain one or more fasteners, the first and second jaws movable in a non-rotational manner relative to one another between an open position and a closed position for retaining the tissue therebetween;
a blade for linearly cutting the section of tissue and a staple driver for driving the fasteners through the tissue and toward the first jaw; and
a first rotatable shaft for effecting the relative movement of the first and second jaws between the open position and the closed position.

24. A device for cutting and fastening a section of tissue, comprising:
-
a first jaw;
a second jaw in opposed correspondence with the first jaw and adapted to retain one or more fasteners, the first and second jaws being movable in a non-rotational manner relative to one another between an open position and a closed position for retaining the tissue therebetween;
a first rotatable shaft for driving the blade;
a blade for cutting the tissue along a path parallel to a plane containing the longitudinal axis of the first shaft; and
a staple driver for driving the fasteners through the tissue and toward the first jaw.
