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;

at least one delivery mechanism adapted to deliver one or more surgical staples, said delivery mechanism being located in a proximity to or contained within said at least one grasping jaw;

said one or more surgical staples containing at least one shape-transforming material; and

at least one chemical tissue sealant.

2. The surgical instrument of claim 1, wherein said 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 said 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 said at least one sensor is disposed within at least one grasping jaw.

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

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

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

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

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

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

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

14. The surgical instrument of claim 1, wherein said chemical tissue sealant is housed inside said at least one grasping law.

15. The surgical instrument of claim 1, wherein said chemical tissue sealant is a biocompatible chemical tissue sealant.

16. The surgical instrument of claim 1, wherein said chemical tissue sealant is a biodegradable chemical tissue sealant.

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

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

19. The surgical instrument of claim 1, wherein said surgical staples include fasteners, pins or ties.

20. A surgical instrument of claim 1, further comprising:

a flexually deformable and steerable shaft connected to said at least one grasping jaw.

21. The surgical instrument of claim 20, wherein said flexually deformable and steerable shaft contains at least one shape-transforming material.

22. The surgical instrument of claim 21, wherein said at least one shape-transforming material contains a shape memory alloy.

23. The surgical instrument of claim 22, wherein said shape memory alloy includes at least one of titanium, nickel, zinc, copper, aluminum, cadmium, platinum, iron, manganese, cobalt, gallium or tungsten.

24. The surgical instrument of claim 22, wherein said shape memory alloy includes Nitinol™

.

25. The surgical instrument of claim 21, wherein said at least one shape-transforming material includes electro-active polymer.
