Abstract

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.

Claims

1. A surgical device, comprising:

a first jaw defining a longitudinal axis;

a second jaw mechanically coupled in opposed relation to the first jaw;

a cutting element disposed within and rotatable relative to the second jaw;

a first sensor electrode disposed on the first jaw and configured to electrically communicate with a first contact pad; and

a second sensor electrode disposed on the second jaw and configured to electrically communicate with a second contact pad, the second contact pad arranged to electrically communicate with the first contact pad.

2. The surgical device according to claim 1, wherein when the first jaw and the second jaw are approximated to a closed configuration, the first sensor electrode contacts the second sensor electrode to complete a sensor circuit.

3. The surgical device according to claim 2, wherein the sensor circuit provides an indication that a cutting and fastening of tissue, disposed between the first jaw and the second jaw, is permitted.

4. The surgical device according to claim 3, wherein the indication is an alert provided to an operator to initiate the cutting and fastening of tissue.

5. The surgical device according to claim 4, wherein the alert is at least one of an audible indication and a visual indication.

6. The surgical device according to claim 2, wherein the contacting of the first sensor electrode and the second sensor electrode automatically activates a cutting and fastening mechanism for cutting and fastening of tissue.

7. The surgical device according to claim 1, wherein the first sensor electrode is in electrical communication with a first contact node, and the second sensor electrode is in electrical communication with a second contact node, the second contact node arranged to electrically communicate with the first contact node.

8. The surgical device according to claim 7, wherein the first sensor electrode and the second sensor electrode are in electrical communication with an electromechanical driver device, via the respective contact nodes, to form a sensor circuit.

9. The surgical device according to claim 1, further comprising:

a first rotatable shaft coupled to the first jaw, wherein a rotation of the first rotatable shaft causes the first jaw to travel linearly in a direction perpendicular to the longitudinal axis; and

a second rotatable shaft arranged in parallel to the longitudinal axis of the first jaw, wherein a rotation of the second rotatable shaft causes a cutting and fastening mechanism to travel linearly in a direction parallel to the longitudinal axes of the first and second jaws.

10. The surgical device according to claim 9, further comprising:

an upper horizontal shaft coupled to a proximal end of the first jaw; and

a lower horizontal shaft extending through the second jaw, the upper horizontal shaft and the lower horizontal shaft configured to be parallel to each other at a fixed distance.

11. 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 defining a longitudinal axis;

a second jaw mechanically coupled in opposed relation to the first jaw;

a cutting element disposed within and rotatable relative to the second jaw;

a first sensor electrode disposed on the first jaw and configured to electrically communicate with a first contact pad; and

a second sensor electrode disposed on the second jaw and configured to electrically communicate with a second contact pad, the second contact pad arranged to electrically communicate with the first contact pad.

12. The electro-mechanical surgical system according to claim 11, wherein when the first jaw and the second jaw are approximated to a closed configuration, the first sensor electrode contacts the second sensor electrode to complete a sensor circuit.

13. The electro-mechanical surgical system according to claim 12, wherein the sensor circuit provides an indication that a cutting and fastening of tissue, disposed between the first jaw and the second jaw, is permitted.

14. The electro-mechanical surgical system according to claim 13, wherein the indication is an alert provided to an operator to initiate the cutting and fastening of tissue.

15. The electro-mechanical surgical system according to claim 14, wherein the alert is at least one of an audible indication and a visual indication.

16. The electro-mechanical surgical system according to claim 12, wherein the contacting of the first sensor electrode and the second sensor electrode automatically activates a cutting and fastening mechanism for cutting and fastening of tissue.

17. The electro-mechanical surgical system according to claim 11, wherein the first sensor electrode is in electrical communication with a first contact node, and the second sensor electrode is in electrical communication with a second contact node, the second contact node arranged to electrically communicate with the first contact node.

18. The electro-mechanical surgical system according to claim 17, wherein the first sensor electrode and the second sensor electrode are in electrical communication with an electromechanical driver device, via the respective contact nodes, to form a sensor circuit.

19. The electro-mechanical surgical system according to claim 11, further comprising:

a first rotatable shaft coupled to the first jaw, wherein a rotation of the first rotatable shaft causes the first jaw to travel linearly in a direction perpendicular to the longitudinal axis; and

a second rotatable shaft arranged in parallel to the longitudinal axis of the first jaw, wherein a rotation of the second rotatable shaft causes a cutting and fastening mechanism to travel linearly in a direction parallel to the longitudinal axes of the first and second jaws.

20. The electro-mechanical surgical system according to claim 19, further comprising:

an upper horizontal shaft coupled to a proximal end of the first jaw; and

a lower horizontal shaft extending through the second jaw, the upper horizontal shaft and the lower horizontal shaft configured to be parallel to each other at a fixed distance.
