Abstract

Embodiments include a surgical device and a method. An embodiment of the surgical instrument includes at least one grasping jaw, the at least one grasping jaw being adapted to deliver surgical staples by a force generated from a force generator mechanism that is contained within the at least one grasping jaw or is in a proximity to the at least one grasping jaw. Another embodiment includes at least one grasping jaw, at least one actuation mechanism adapted to deliver surgical staples, the actuation mechanism being located in a proximity to or contained within the at least one grasping jaw, the surgical staples containing at least one shape-transforming material, at least one sensor, at least one chemical tissue sealant and at least one cutter. A method includes: grasping a body tissue with at least one grasping jaw, adjusting a configuration of the grasping in response to a signal or a datum or an image, and releasing a surgical staple/fastener in response to the signal, datum or image.

Claims

1. A surgical instrument comprising:

at least one grasping jaw, including a shape memory alloy and configured for grasping a body tissue;

at least one delivery mechanism adapted to deliver one or more surgical staples and operably coupled to control circuitry, the delivery mechanism contained within the at least one grasping jaw;

at least one chemical tissue sealant reservoir contained within or located in proximity to the at least one grasping jaw, and operably coupled to the control circuitry;

a trigger operably coupled to the control circuitry, wherein said at least one chemical tissue sealant reservoir and said at least one delivery mechanism are responsive to a signal generated by said trigger; and

a flexually deformable and steerable shaft connected to the at least one grasping jaw, and containing at least one shape memory alloy.

2. The surgical instrument of claim 1, wherein the at least one grasping jaw is configured to movably operate in an opposing manner with respect to at least one other grasping jaw.

3. The surgical instrument of claim 1, wherein the at least one grasping jaw is configured to operably mate with at least one other grasping jaw.

4. The surgical instrument of claim 1, further comprising at least one sensor.

5. The surgical instrument of claim 4, wherein the at least one sensor is disposed within at least one grasping jaw.

6. The surgical instrument of claim 4, wherein the at least one sensor is disposed in a proximity to at least one grasping jaw.

7. The surgical instrument of claim 4, wherein the at least one sensor includes an image-acquisition device.

8. The surgical instrument of claim 7, wherein the image-acquisition device includes at least one of a camera, a charge coupled device, an X-ray receiver, an acoustic energy receiver, an electromagnetic energy receiver or an imaging device.

9. The surgical instrument of claim 7, wherein the image-acquisition device is wirelessly coupled or hardwired to at least one visual display.

10. The surgical instrument of claim 4, wherein the sensor includes an illumination device that is operably coupled to at least one image-acquisition device.

11. The surgical instrument of claim 4, wherein the at least one sensor includes a data-transmission device.

12. The surgical instrument of claim 4, wherein the at least one sensor includes a proximity detector.

13. The surgical instrument of claim 12, wherein the proximity detector is adapted to detect proximity of a biological tissue to the surgical instrument.

14. The surgical instrument of claim 1, wherein the chemical tissue sealant is a biocompatible chemical tissue sealant.

15. The surgical instrument of claim 1, wherein the chemical tissue sealant is a biodegradable chemical tissue sealant.

16. The surgical instrument of claim 1, wherein the chemical tissue sealant is delivered in a proximity to the at least one staple.

17. The surgical instrument of claim 1, wherein the chemical tissue sealant is delivered between at least two adjacent layers of body tissue.

18. The surgical instrument of claim 1, wherein the surgical staples include fasteners, pins or ties.

19. The surgical instrument of claim 1, wherein the chemical tissue sealant includes at least one of a liquid, solid, or semi-solid.

20. A surgical instrument comprising:

at least one grasping jaw, including a shape memory alloy and configured for grasping a body tissue;

at least one delivery mechanism adapted to deliver one or more surgical staples and operably coupled to control circuitry, the delivery mechanism contained within the at least one grasping jaw;

at least one chemical tissue sealant reservoir contained within or located in proximity to the at least one grasping jaw, and operably coupled to the control circuitry;

a trigger operably coupled to the control circuitry, wherein said at least one chemical tissue sealant reservoir and said at least one delivery mechanism are responsive to a signal generated by said trigger, and at least one energy module contained within the at least one grasping jaw.

21. The surgical instrument of claim 20, wherein the at least one energy module is operably linked to the at least one chemical tissue sealant reservoir.

22. The surgical instrument of claim 20, wherein the at least one grasping jaw is configured to movably operate in an opposing manner with respect to at least one other grasping jaw.

23. The surgical instrument of claim 20, wherein the at least one grasping jaw is configured to operably mate with at least one other grasping jaw.

24. The surgical instrument of claim 20, further comprising at least one sensor.

25. The surgical instrument of claim 24, wherein the at least one sensor is disposed within at least one grasping jaw.

26. The surgical instrument of claim 24, wherein the at least one sensor is disposed in a proximity to at least one grasping jaw.

27. The surgical instrument of claim 24, wherein the at least one sensor includes an image-acquisition device.

28. The surgical instrument of claim 27, wherein the image-acquisition device includes at least one of a camera, a charge coupled device, an X-ray receiver, an acoustic energy receiver, an electromagnetic energy receiver or an imaging device.

29. The surgical instrument of claim 27, wherein the image-acquisition device is wirelessly coupled or hardwired to at least one visual display.

30. The surgical instrument of claim 24, wherein the sensor includes an illumination device that is operably coupled to at least one image-acquisition device.
