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 delivery mechanism adapted to deliver surgical fasteners, the delivery mechanism being located in a proximity to or contained within the at least one grasping jaw, the surgical fasteners 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 organ/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 configured for grasping a body tissue and including a shape memory alloy, said at least one grasping jaw being adapted to deliver surgical staples responsive to an actuation force; and

a force generator mechanism that is contained within said at least one grasping jaw and said force generator mechanism being operably coupled to control circuitry, and a trigger operably coupled to the control circuitry, wherein said force generator mechanism is responsive to a signal generated by said trigger.

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, wherein said at least one grasping jaw is configured to serve as an anvil for forming an interaction surface between at least one surgical staple and bodily tissues, said forming being facilitated by reversible mating and unmating of said anvil with an opposite grasping jaw.

5. The surgical instrument of claim 1, wherein said force generated from said force generator mechanism is communicated to a medium resulting in the release of at least one surgical staple.

6. The surgical instrument of claim 1, wherein said force generated from said force generator mechanism results in delivery of one or more linear rows of surgical staples.

7. The surgical instrument of claim 1, further comprising at least one energy module, said energy module includes at least one of a battery, a capacitor, a fuel cell, a mechanical energy storage device, and/or a fluid energy storage device.

8. The surgical instrument of claim 7, wherein said energy module transmits energy through a wireless device.

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

10. The surgical instrument of claim 9, wherein said at least one sensor includes an image-acquisition device.

11. The surgical instrument of claim 9, wherein said sensor includes an illumination device that is operably coupled to at least one image-acquisition device.

12. The surgical instrument of claim 11 wherein said image-acquisition device is wirelessly coupled to at least one visual display.

13. The surgical instrument of claim 9, wherein said at least one sensor includes a proximity detector.

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

15. The surgical instrument of claim 9, wherein said at least one sensor provides a force feedback signal to said force generator mechanism.

16. The surgical instrument of claim 1, wherein the at least one grasping jaw is operably coupled to control circuitry and is responsive to the signal generated by said trigger.

17. The surgical instrument of claim 1, further comprising a flexually deformable and steerable shaft is operably coupled to control circuitry and is responsive to the signal generated by said trigger.
