a surgical stapling attachment coupleable to the first and second drive components of the shaft, the surgical stapling attachment including a stapling portion, a blade, and an anvil;
at least one sensor in the surgical stapling attachment, the at least one sensor being arranged to confirm that tissue to be stapled together is disposed between the stapling portion and the anvil;
a first motor connected to a first drive component, the first motor configured to be actuated by a first actuation switch;
a second motor connected to a second drive component, the second motor configured to be actuated by a second actuation switch; and
a drive switch configured to selectively alter a turning direction of at least one of the first and second motors.
2. The medical device of claim 1 , wherein the at least one sensor includes a pulse oximetry sensor.
3. The medical device of claim 1 , wherein the shaft has a distal end configured to couple with surgical stapling attachments having one or more of different diameters, shapes, lengths and stapling arrangements.
4. The medical device of claim 1 , wherein the stapling portion has a circular shape.
5. The medical device of claim 1 , further comprising a remote status indicator.
6. The medical device of claim 1 , further comprising a controller having a processor and a memory unit.
7. The medical device of claim 6 , wherein the controller and electromechanical driver are integral components.
8. The medical device of claim 1 , further comprising an output display device.
9. The medical device of claim 1 , wherein the electromechanical driver is disposed in a handle.
10. The medical device of claim 9 , wherein the elongate shaft is removably attached to the handle.
11. The medical device of claim 1 , wherein the at least one sensor includes a light detecting element.
12. The medical device of claim 1 , wherein the shaft is flexible.
13. The medical device of claim 1 , wherein the shaft is steerable.
14. The medical device of claim 13 , further comprising steering wires for steering the shaft.
15. The medical device of claim 1 , wherein at least one of the first and second drive components rotates.
16. The medical device of claim 15 , wherein the surgical stapling attachment includes a nut, the blade and a staple driver being attached to the nut.
17. The medical device of claim 16 , wherein the nut is mounted on the rotatable first and second drive components.
18. The medical device of claim 1 , further comprising a memory unit disposed in the surgical stapling attachment.
19. The medical device of claim 1 , further comprising a controller that communicates wirelessly.
20. A medical device, comprising;
an electromechanical driver;
an elongate shaft having first and second drive components actuatable by the electromechanical driver;
a surgical stapling attachment coupleable to the first and second drive components of the shaft, the surgical stapling attachment including a stapling portion, a blade, and an anvil;
a plurality of sensors around a circumferential rim of the stapling portion, the sensors being arranged to confirm that tissue to be stapled together is disposed between the stapling portion and the anvil;
a first motor connected to a first drive component, the first motor configured to be actuated by a first actuation switch;
a second motor connected to a second drive component, the second motor configured to be actuated by a second actuation switch; and
a drive switch configured to selectively alter a turning direction of at least one of the first and second motors.
21. A medical device, comprising:
an electromechanical driver;
an elongate shaft having first and second drive components actuatable by the electromechanical driver;
a surgical stapling attachment coupleable to the first and second drive components of the shaft, the surgical stapling attachment including a stapling portion, a blade, and an anvil;
at least one sensor in the surgical stapling attachment, the at least one sensor being arranged to determine a distance between the stapling portion and the anvil;
a controller component arranged to interact with the at least one sensor and to determine the distance between the stapling portion and the anvil;
a first motor connected to a first drive component, the first motor configured to be actuated by a first actuation switch;
a second motor connected to a second drive component, the second motor configured to be actuated by a second actuation switch; and
a drive switch configured to selectively alter a turning direction of at least one of the first and second motors.
