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 fasteners, the actuation 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:

a flexually deformable and steerable shaft, operably coupled to a grasping jaw configured to grasp a body tissue, and including at least one cutter and stapler;

at least one sensor operably coupled to a force receiver; and

control circuitry configured to control the at least one grasping jaw in response to one or more signals from the at least one sensor.

2. The surgical instrument of claim 1, further including at least one energy module.

3. The surgical instrument of claim 2, wherein the at least one energy module includes at least one of a battery, capacitor, fuel cell, mechanical energy storage device, or fluid energy storage device.

4. The surgical instrument of claim 1, wherein the at least one sensor is configured to communicate at least one of a signal, datum, or image to a human or robotic user.

5. The surgical instrument of claim 1, wherein the at least one sensor is configured to communicate at least one of a signal, datum, or image regarding the number of staples in the surgical instrument.

6. The surgical instrument of claim 1, wherein the at least one sensor is configured to provide at least one of a signal, datum, or image regarding the functional or malfunctional status of the surgical instrument.

7. The surgical instrument of claim 1, wherein the at least one sensor is configured to provide a force feedback signal to a delivery mechanism contained in the at least one grasping jaw.

8. The surgical instrument of claim 1, wherein the flexually deformable and steerable shaft includes at least one shape memory alloy.

9. The surgical instrument of claim 8, wherein the at least one shape memory alloy includes at least one of titanium, nickel, zinc, copper, aluminum, cadmium, platinum, iron, manganese, cobalt, gallium or tungsten.

10. The surgical instrument of claim 8, wherein the shape memory alloy includes Nitinol™

.

11. The surgical instrument of claim 8, wherein the at least one shape memory alloy includes electro-active polymer.

12. The surgical instrument of claim 1, wherein the flexually deformable and steerable shaft being controllably deformable to permit a high degree of maneuverability of the surgical instrument includes controllable deformation of the 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.

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

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

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

16. The surgical instrument of claim 1, further including at least one proximity detector disposed in the at least one grasping jaw or located in proximity to the at least one grasping jaw.

17. The surgical instrument of claim 16, wherein the proximity detector is adapted to detect whether a biological tissue is partly within grasping distance of the grasping jaw.

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

19. The surgical instrument of claim 16, wherein the proximity detector is operably coupled to at least one data-transmission device.

20. The surgical instrument of claim 16 wherein the proximity detector includes an electromagnetic energy emitter or an electromagnetic energy receiver.

21. The surgical instrument of claim 16, wherein the proximity detector includes an acoustic energy emitter or an acoustic energy receiver.

22. The surgical instrument of claim 16, wherein the proximity detector includes a point source emitter or a source illuminator.

23. The surgical instrument of claim 22, wherein the point source emitter or source illuminator includes at least one of an ultrasonic source, acoustic source, visible source, ultraviolet source, gamma ray source, X-ray source, or infrared source.
