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 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:

a flexually deformable and steerable shaft including at least one shape memory alloy, operably connected to at least one grasping jaw having a force generator mechanism that is contained within said at least one grasping jaw, said flexually deformable and steerable shaft being controllably deformable to permit a high degree of maneuverability of said surgical instrument.

2. The surgical instrument of claim 1, wherein said flexually deformable and steerable shaft is enclosed in a bendable and steerable tube or a sheath.

3. The surgical instrument of claim 1, wherein said at least one shape memory alloy includes at least one of titanium, nickel, zinc, copper, aluminum, cadmium, platinum, iron, manganese, cobalt, gallium or tungsten.

4. The surgical instrument of claim 1, wherein said at least one shape memory alloy is preconfigured to a particular application and to a body part geometry.

5. The surgical instrument of claim 1, wherein said at least one shape memory alloy assumes a different shape compared to an originally preconfigured shape to conform to an optimal orientation upon insertion of said surgical instrument into a body.

6. The surgical instrument of claim 1, wherein said shape memory alloy includes Nitinol™

.

7. The surgical instrument of claim 1, wherein said at least one shape memory alloy includes electro-active polymer.

8. The surgical instrument of claim 1, wherein said at least one shape memory alloy includes at least one mechanically reconfigurable material.

9. The surgical instrument of claim 1, wherein said flexually deformable and steerable shaft being controllably deformable to permit a high degree of maneuverability of said surgical instrument includes controllable deformation of said shaft that is mediated by at least one of a temperature profile, a pressure profile, an electrical circuitry, a magnetic profile, an acoustic wave profile or an electro-magnetic radiation profile.

10. The surgical instrument of claim 1, wherein said flexually deformable and steerable shaft being controllably deformable to permit a high degree of maneuverability of said surgical instrument includes maneuverability and steerability of said surgical instrument around anatomical corners or difficult-to-reach anatomical body parts that are normally inaccessible on a straight trajectory.

11. The surgical instrument of claim 1, wherein said flexually deformable and steerable shaft being controllably deformable to permit a high degree of maneuverability of said surgical instrument includes bending said shaft in real time to navigate within a body space.

12. The surgical instrument of claim 1, wherein said flexually deformable and steerable shaft returns to an original shape or configuration for easy removal of said surgical instrument from a body.

13. The surgical instrument of claim 1, wherein said surgical instrument is a surgical stapler that is adapted to deliver staples, fasteners, pins or ties.

14. The surgical instrument of claim 1, further comprising at least one grasping jaw having a proximity detector.

15. The surgical instrument of claim 14, wherein said proximity detector is adapted to detect whether a biological tissue is partly within grasping distance of said grasping jaw.

16. The surgical instrument of claim 14, wherein said proximity detector is adapted to detect whether a biological tissue is fully within grasping distance of said grasping jaw.

17. The surgical instrument of claim 14, wherein said proximity detector is operably configured to assess whether an entire organ or a portion of a bodily organ is fully or partly grasped within said grasping jaw.

18. The surgical instrument of claim 1, further comprising at least one grasping jaw that is fully redeployable following at least one grasp-and-release cycle in a grasping operation of a biological tissue or bodily organ.

19. The surgical instrument of claim 1, further comprising at least one grasping jaw that is independently maneuverable from an attached shaft or a sheath.

20. 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.

21. 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.

22. 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.

23. The surgical instrument of claim 1, wherein said at least one grasping jaw forms an annular grasp around a body tissue.
