Abstract

The present invention is a device and method of using a variety of laparoscopic or NOTES surgical tools at a confined or inaccessible space, e.g., an intra-abdominal surgical and NOTES tool inserted through a single incision through the skin or hollow viscus. Generally, the laparoscopic or NOTES surgical devices include a device body having a first side and a second side, wherein the first side includes a positioning mechanism and the second side includes one or more of a variety of laparoscopic or NOTES tools.

Claims

1. A surgical electro-cautery device comprising:

a device body;

a first magnetic or ferrous material in a first portion of the device body;

a second magnetic or ferrous material in a second portion of the device body, the first and second portions of the device body being spaced apart from each other; and

an electro-cautery surgical mechanism coupled to the device body, the electro-cautery surgical mechanism including a rotation mechanism.

2. The device of claim 1, wherein the device body further comprises, a suction region.

3. The device of claim 1, further comprising a camera, a light or combination thereof disposed in or about the device body.

4. The device of claim 1, wherein the electro-cautery surgical mechanism comprises a straight electro-cautery tip positioned on a moveable extension.

5. The device of claim 1, wherein the electro-cautery surgical mechanism comprises a flexible shaft.

6. The device of claim 1, wherein the electro-cautery surgical mechanism is internally powered, externally powered, or a combination thereof.

7. The device of claim 1, wherein the electro-cautery surgical mechanism is hydraulically or pneumatically powered.

8. The device of claim 1, further comprising a drawstring for removing the device.

9. The device of claim 1, wherein the device body comprises a surgical plastic.

10. The device of claim 1, further comprising a casing comprising a first material and a second material, the first and second materials being configured and positioned to magnetically couple to the first and second magnetic or ferrous materials in the device body such that the position of the device body within a body cavity or viscus can be changed by manipulating the casing outside the body cavity or viscus.

11. A surgical electro-cautery device comprising:

a device body;

a first magnetic or ferrous material in a first portion of the device body;

a second magnetic or ferrous material in a second portion of the device body, the first and second portions of the device body being spaced apart from each other; and

an electro-cautery surgical mechanism coupled to the device body, the electro-cautery surgical mechanism having a straight electro-cautery tip.

12. The device of claim 11, further comprising a casing comprising a first material and a second material, the first and second materials being configured and positioned to magnetically couple to the first and second magnetic or ferrous materials in the device body such that the position of the device body within a body cavity or viscus can be changed by manipulating the casing outside the body cavity or viscus.

13. The device of claim 11, further comprising a camera, a light or combination thereof disposed in or about the device body.

14. The device of claim 11, wherein the electro-cautery surgical mechanism comprises a flexible shaft.

15. The device of claim 11, wherein the electro-cautery surgical mechanism is internally powered, externally powered, or a combination thereof.

16. The device of claim 11, wherein the electro-cautery surgical mechanism is hydraulically or pneumatically powered.

17. The device of claim 11, further comprising a drawstring for removing the device.

18. The device of claim 11, wherein the device body comprises a surgical plastic.

19. A surgical electro-cautery device comprising:

a device body having a leading end a trailing end;

a first magnetic or ferrous material in a first portion of the device body;

a second magnetic or ferrous material in a second portion of the device body, the first and second portions of the device body being spaced apart from each other;

an electro-cautery surgical mechanism coupled to the device body at a location nearer the trailing end than the leading end; and

a camera and a light coupled to the device body at respective locations that are nearer the leading end than the trailing end.

20. The device of claim 19, further comprising a casing comprising a first material and a second material, the first and second materials being configured and positioned to magnetically couple to the first and second magnetic or ferrous materials in the device body such that the position of the device body within a body cavity or viscus can be changed by manipulating the casing outside the body cavity or viscus.

21. The device of claim 19, wherein the electro-cautery surgical mechanism comprises a flexible shaft.

22. The device of claim 19, wherein the electro-cautery surgical mechanism is internally powered, externally powered, or a combination thereof.

23. The device of claim 19, wherein the electro-cautery surgical mechanism is hydraulically or pneumatically powered.

24. The device of claim 19, further comprising a drawstring for removing the device.

25. The device of claim 19, wherein the device body comprises a surgical plastic.
