Claims

1. A segmented medical device, the system comprising:

(a) a first body segment configured to be disposed inside a cavity of a patient, the segment comprising

(i) a first operational component associated with the first body segment; and

(ii) a first mating component at a first end of the first body segment;

(b) a second body segment configured to be disposed inside the cavity of the patient, the segment comprising

(i) a second operational component associated with the second body segment; and

(ii) a first pivotal coupling at a first end of the second body segment, whereby the second body segment is pivotally coupled to a second end of the first body segment;

(c) a third body segment configured to be disposed inside the cavity of the patient, the segment comprising

(i) a third operational component associated with the third body segment;

(ii) a second pivotal coupling at a first end of the third body segment, whereby the third body segment is pivotally coupled to a second end of the second body segment; and

(iii) a second mating component at a second end of the third body segment, the second mating component configured to be coupleable with the first mating component; and

(d) an attachment component associated with the segmented medical device, wherein the attachment component comprises a rod coupled to the segmented medical device, wherein the rod is configured to extend from the segmented medical device out of the cavity of the patient.

2. The segmented medical device of claim 1, wherein the device is configured to move between an open position in which the first and second mating components are not coupled together and a closed position in which the first and second mating components are coupled.

3. The segmented medical device of claim 2, wherein the first, second, and third body segments define an opening in the closed position.

4. The segmented medical device of claim 3, wherein the attachment component is disposed in the opening.

5. The segmented medical device of claim 1, wherein the first pivotal coupling and the second pivotal coupling comprise tensioned components configured to urge the first mating component and the second mating component toward each other.

6. The segmented medical device of claim 1, wherein the first body segment comprises a first inner cylindrical component disposed within a first outer cylindrical component, wherein the first inner cylindrical component is rotatable in relation to the first outer cylindrical component.

7. The segmented medical device of claim 6, wherein the first inner cylindrical component comprises a first inner opening and the first outer cylindrical component comprises a first outer opening, wherein the first inner cylindrical component and the first outer cylindrical component are rotatable such that the first inner opening and first outer opening align, thereby providing access to an interior portion of the first inner cylindrical component.

8. The segmented medical device of claim 7, wherein the first operational component is configured to move between an undeployed position disposed within the interior portion of the first inner cylindrical component and a deployed position in which a portion of the first operational component is disposed outside of the first inner cylindrical component through the first inner opening and first outer opening.

10. The segmented medical device of claim 2, wherein the first, second, and third body segments define an opening in the closed position, wherein the attachment component is disposed in the substantially central location in the opening.

12. The segmented medical device of claim 1, wherein

(a) the first body segment comprises a first inner cylindrical component disposed within a first outer cylindrical component, wherein the first inner cylindrical component is rotatable in relation to the first outer cylindrical component;

(b) the second body segment comprises a second inner cylindrical component disposed within a second outer cylindrical component, wherein the second inner cylindrical component is rotatable in relation to the second outer cylindrical component; and

(c) the third body segment comprises a third inner cylindrical component disposed within a third outer cylindrical component, wherein the third inner cylindrical component is rotatable in relation to the third outer cylindrical component.

13. The segmented medical device of claim 12, wherein

(a) the first inner cylindrical component comprises a first inner opening and the first outer cylindrical component comprises a first outer opening, wherein the first inner cylindrical component and the first outer cylindrical component are rotatable such that the first inner opening and first outer opening align, thereby providing access to an interior portion of the first inner cylindrical component;

(b) the second outer cylindrical component comprises a second outer opening, wherein the second inner cylindrical component and the second outer cylindrical component are rotatable such that the second operational component is accessible through the second outer opening; and

(c) the third inner cylindrical component comprises a third inner opening and the third outer cylindrical component comprises a third outer opening, wherein the third inner cylindrical component and the third outer cylindrical component are rotatable such that the third inner opening and third outer opening align, thereby providing access to an interior portion of the third inner cylindrical component.

14. The segmented medical device of claim 13, wherein

(a) the first operational component is configured to move between an undeployed position disposed within the interior portion of the first inner cylindrical component and a deployed position in which a portion of the first operational component is disposed outside of the first inner cylindrical component through the first inner opening and first outer opening;

and

(b) the third operational component is configured to move between an undeployed position disposed within the interior portion of the third inner cylindrical component and a deployed position in which a portion of the third operational component is disposed outside of the third inner cylindrical component through the third inner opening and third outer opening.

15. The segmented device of claim 14, wherein the first operational component comprises a grasper and the second operational component comprises a cautery hook.

16. The segmented device of claim 1, wherein the second operational component comprises at least one camera or at least one light.

9. A segmented medical device, the system comprising:

(a) a first body segment configured to be disposed inside a cavity of a patient, the segment comprising

(i) a first operational component associated with the first body segment; and

(ii) a first mating component at a first end of the first body segment;

(b) a second body segment configured to be disposed inside the cavity of the patient, the segment comprising
