A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws. The device may also include a stapling element disposed within the second jaw. The cutting element and the stapling element may be contiguous so as to define a cutting and stapling element, such as a wedge having a blade disposed thereon. As the wedge is moved proximally from the distal end of the second jaw to the proximal end, the wedge pushes a plurality of staples against a plurality of opposing staple guides disposed in the first jaw in order to staple a section of tissue while cutting the section of tissue.
1. A surgical device, comprising: a first jaw;a second jaw mechanically coupled in opposed relation to the first jaw;a cutting element disposed within and rotatable relative to the second jaw; anda first driver configured to move the cutting element proximally from an initial position at a distal en
1. A surgical device, comprising: a first jaw;a second jaw mechanically coupled in opposed relation to the first jaw;a cutting element disposed within and rotatable relative to the second jaw; anda first driver configured to move the cutting element proximally from an initial position at a distal end of the second jaw toward a proximal end of the second jaw to cut tissue disposed between the first and second jaws. 2. The surgical device according to claim 1, wherein the cutting element is in a retracted position in the initial position with a cutting edge of the cutting element unexposed to prevent cutting of tissue, and is rotatable to an unretracted position with the cutting edge of the cutting element exposed to cut tissue. 3. The surgical device according to claim 1, wherein the cutting element rotates from a first angular orientation at the initial position to a second angular orientation in the unretracted position;wherein, in the first angular orientation, a cutting edge of the cutting element is unexposed to prevent cutting of tissue; andwherein, in the second angular orientation, the cutting edge of the cutting element is exposed to cut tissue during proximal movement of the cutting element from the distal end of the second jaw toward the proximal end of the second jaw. 4. The surgical device according to claim 1, further comprising an actuating member fixed relative to the second jaw and disposed adjacent to an actuating member receiving face of the cutting element, such that the actuating member receiving face engages the fixed actuating member during proximal movement of the cutting element, so as to cause the cutting element to rotate about a pivot. 5. The surgical device according to claim 1, further comprising a stapling element disposed within the second jaw, wherein the cutting element and the stapling element are contiguous so as to comprise a cutting and stapling element. 6. The surgical device according to claim 5, wherein the cutting and stapling element includes a wedge having a blade disposed thereon. 7. The surgical device according to claim 6, wherein the cutting and stapling element is seated in a wedge guide channel formed in the second jaw. 8. The surgical device according to claim 7, wherein the blade is rotatably coupled to the wedge. 9. The surgical device according to claim 8, wherein the blade is rotatable relative to the wedge between a retracted position and a cutting position when the cutting and stapling element moves proximally. 10. The surgical device according to claim 1, wherein the first and second jaws are disposed in parallel correspondence in both open and closed positions. 11. The surgical device according to claim 10, wherein the first and second jaws are arranged in scissor fashion, such that the first and second jaws are disposed in parallel correspondence in the closed position and, when in the open position, a distance between distal ends of the first and second jaws is greater than a distance between the proximal ends of the first and second jaws. 12. An electro-mechanical surgical system, comprising: an elongated shaft;a first axially rotatable drive shaft disposed within the elongated shaft;a surgical device configured to detachably couple to a distal end of the elongated shaft, wherein the surgical device includes: a first jaw;a second jaw mechanically coupled in opposed relation to the first jaw;a cutting element disposed within and rotatable relative to the second jaw; anda first driver configured to move the cutting element proximally from an initial position at a distal end of the second jaw toward a proximal end of the second jaw to cut tissue disposed between the first and second jaws. 13. The electro-mechanical surgical system according to claim 12, further comprising a motor system configured to drive the first axially rotatable drive shaft. 14. The electro-mechanical surgical system according to claim 12, wherein the cutting element is in a retracted position in the initial position with a cutting edge of the cutting element unexposed to prevent cutting of tissue, and is rotatable to an unretracted position with the cutting edge of the cutting element exposed to cut tissue. 15. The electro-mechanical surgical system according to claim 12, wherein the cutting element rotates from a first angular orientation at the initial position to a second angular orientation;wherein, in the first angular orientation, a cutting edge of the cutting element is unexposed to prevent cutting of tissue; andwherein, in the second angular orientation, the cutting edge of the cutting element is exposed to cut tissue during proximal movement of the cutting element from the distal end of the second jaw toward the proximal end of the second jaw. 16. The electro-mechanical surgical system according to claim 12, further comprising an actuating member fixed relative to the second jaw and disposed adjacent to an actuating member receiving face of the cutting element, such that the actuating member receiving face engages the fixed actuating member during proximal movement of the cutting element, so as to cause the cutting element to rotate about a pivot. 17. The electro-mechanical surgical system according to claim 12, further comprising a stapling element disposed within the second jaw, wherein the cutting element and the stapling element are contiguous so as to comprise a cutting and stapling element. 18. The electro-mechanical surgical system according to claim 17, wherein the cutting and stapling element includes a wedge having a blade disposed thereon;wherein the cutting and stapling element is seated in a wedge guide channel formed in the second jaw; andwherein the blade is rotatably coupled to the wedge. 19. The electro-mechanical surgical system according to claim 12, further comprising a control system configured to control the motor system, the motor system including a first motor configured to drive the first axially rotatable drive shaft and a second motor configured to drive a second axially rotatable drive shaft. 20. The electro-mechanical surgical system according to claim 19, further comprising a remote control unit configured to communicate with the control system to control the motor system, wherein the remote control unit includes at least one of a wired remote control unit and a wireless remote control unit.
