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.

The device of claim 5,wherein one or more of the fasteners are staples, and wherein the first surface of the first jaw includes one or more staple guides corresponding to the prongs of the staples, each staple guide forming a pair of concave pockets adapted to receive the prongs of the staples and thereafter guide the prongs toward a bent closed position. 7. The device of claim 6,comprising a removable staple tray housing the staples, and wherein the second surface of the second jaw is adapted to receive the removable staple tray. 8. The device of claim 3, wherein the threaded shaft has a proximal end mechanically communicating with a means for rotating the threaded shaft.9. The device of claim 8, wherein the means is a motor.10. The device of claim 9,wherein the motor has a drive extension having a distal end, and wherein the proximal end of the threaded shaft has a drive socket adapted to receive the distal end of the drive extension. 11. The device of claim 8,wherein one of a clockwise rotation and a counter-clockwise rotation of the threaded shaft causes the wedge to travel away from the proximal end of the threaded shaft, and wherein the other of the clockwise rotation and the counter-clockwise rotation of the threaded shaft causes the wedge to travel toward the proximal end of the threaded shaft. 12. The device of claim 3, wherein the threaded bore of the wedge is a threaded channel.13. The device of claim 1, including a sensor for sensing when the first jaw is adjacent to the second jaw.14. The device of claim 13,wherein the sensor includes a first electrical contact on the first jaw and a second electrical contact on the second jaw, each of the first and second electrical contacts being in electrical communication with a proximity sensing circuit such that when the first and second electrical contacts are touching, the proximity sensing circuit is closed. 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; 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 blade and the staple driver. 16. The device according to claim 15, wherein the second rotatable shaft has outer threads for driving the blade and the staple driver.17. The device according to claim 16, wherein the second rotatable shaft is adapted to drive the staple driver and the blade simultaneously.18. The device according to claim 16, comprising a first motor for driving the first rotatable shaft and a second motor for driving the second rotatable shaft.19. The device according to claim 16, comprising a motor arrangement for driving each of the first rotatable shaft and the second rotatable shaft.20.
