Abstract

A cannula assembly includes a tubular element forming a lumen, a deployable portion of the tubular element, and an electronic component mounted to the deployable portion of the tubular element. The tubular element has a proximal end and a distal end adapted to be inserted into a body cavity. The deployable portion of the tubular element is engaged near the distal end of the tubular element so as to transition between a closed position and an open position. The electronic component is at least partially disposed in the lumen when the deployable portion is in the closed position.

Claims

1. A cannula assembly comprising:

a tubular element forming a lumen, the tubular element having a proximal end and a distal end adapted to be inserted into a body cavity;

a deployable portion of the tubular element, engaged near the distal end of the tubular element so as to transition between a closed position and an open position; and

an electronic component mounted to the deployable portion of the tubular element, wherein the electronic component is at least partially disposed in the lumen when the deployable portion is in the closed position.

2. The cannula assembly of claim 1, wherein the open position comprises a range of positions.

3. The cannula assembly of claim 1, wherein the electronic component is disposed remotely from the lumen when the deployable portion is in the open position.

4. The cannula assembly of claim 1, wherein the deployable portion comprises a wall portion of the tubular element.

5. The cannula assembly of claim 1 further comprising a removable trocar adapted to fit into the lumen when the deployable portion is in the closed position.

6. The cannula assembly of claim 1, wherein the deployable portion forms a pointed tip at the distal end of the tubular element when the deployable portion is in the closed position.

7. The cannula assembly of claim 6, wherein the pointed tip comprises an optically transparent material, so as to project an image through the pointed tip onto the electronic component when the deployable portion is in the closed position.

8. The cannula assembly of claim 1, wherein the electronic component is selected from the group consisting of an image transmission component, an illumination component, and combinations thereof.

9. The cannula assembly of claim 8, wherein the image transmission component is selected from the group consisting of a charge-coupled device camera, a complementary metal oxide semiconductor imaging device, and a fiber optic cable.

10. The cannula assembly of claim 8, wherein the illumination component is selected from the group consisting of a light source and a fiber optic cable.

11. The cannula assembly of claim 10, wherein the light source is selected from the group consisting of a light emitting diode, an organic light emitting diode, a filament lamp, an electroluminescent source, and a laser source.

12. The cannula assembly of claim 1, wherein the deployable portion of the tubular element transitions between the open position and the closed position via a hinge arrangement.

13. The cannula assembly of claim 12, wherein the hinge arrangement is disposed in the tubular element.

14. The cannula assembly of claim 13, wherein the hinge arrangement comprises a pivot.

15. The cannula assembly of claim 12, wherein the hinge arrangement is disposed on a circumference of the tubular element.

16. The cannula assembly of claim 15, wherein the hinge arrangement comprises a circumferential hinge.

17. The cannula assembly of claim 12, wherein the hinge arrangement is disposed on an exterior of the tubular element.

18. The cannula assembly of claim 17, wherein the hinge arrangement comprises at least one four-bar linkage.

19. The cannula assembly of claim 1 further comprising an actuation mechanism configured to transition the deployable portion between the closed position and the open position.

20. The cannula assembly of claim 19, wherein the actuation mechanism comprises:

a knob disposed near the proximal end;

at least one link coupled to the knob; and

a hinge arrangement coupled to the at least one link and the deployable portion, wherein rotation of the knob moves the deployable portion between the open position and the closed position.
