Abstract

The present disclosure is directed to arthroscopic visualization systems and methods. The visualization system can include a camera with a fluid inflow path, wherein a proximal end of the camera is configured to fluidly connect a fluid reservoir to the fluid inflow path. The system can also include a cannula with a lumen, wherein the lumen is configured to be fluidly connected to the fluid inflow path at a distal end of the camera. In addition, the system can also include a scope, wherein the scope is configured to be connected to the distal end of the camera and a portion of the scope is configured to be inserted into the lumen of the cannula.

First claim

The invention claimed is:

1. A visualization system for medical procedures comprising:
a camera comprising a body longitudinally extending between a proximal end and a distal end and having a fluid inflow path, wherein the proximal end of the camera body is configured to fluidly connect a fluid reservoir to the fluid inflow path;
a cannula comprising a lumen, wherein the lumen is configured to be fluidly connected to the fluid inflow path at the distal end of the camera body; and
a scope, wherein the scope is configured to be connected to the distal end of the camera body and a portion of the scope is configured to be inserted into the lumen of the cannula, wherein the scope and cannula are configured to be rotatably connected to the distal end of the camera body and the scope and cannula are configured to rotate independent of the camera body.

2. The system of claim 1 , wherein the scope comprises a light source.

3. The system of claim 1 , wherein the camera comprises a light source.

4. The system of claim 1 , wherein the scope is configured to be optically connected to the camera.

5. The system of claim 1 , wherein the cannula comprises a fluid outlet at a distal end of the cannula fluidly connected to the lumen.

6. The system of claim 1 , wherein the camera comprises a fluid outflow path and the proximal end of the camera body is configured to fluidly connect the fluid outflow path to a fluid waste.

7. The system of claim 1 , wherein the cannula comprises a second lumen.

8. The system of claim 7 , wherein the second lumen is configured to be fluidly connected to a fluid outflow path at the distal end of the camera body.

9. The system of claim 7 , wherein the cannula comprises a non-permeable barrier separating the lumen from the second lumen.

10. The system of claim 7 , wherein the lumen and the second lumen are parallel.

11. The system of claim 7 , wherein the lumen and the second lumen are multi-lumens, not co-axial.

12. The system of claim 7 , wherein the cannula comprises a fluid inlet between a proximal end and a distal end of the cannula fluidly connected to the second lumen.

13. The system of claim 7 , wherein a cross sectional area of the second lumen and the lumen decreases from a proximal end of the cannula towards a distal end of the cannula.

14. The system of claim 7 , further comprising a fluid manifold configured to be connected to the camera body and the cannula, wherein the fluid manifold fluidly couples the fluid inflow path of the camera body to the lumen and a fluid outflow path to the second lumen.

15. The system of claim 14 , wherein the cannula is configured to be rotatably connected to the fluid manifold.

16. The system of claim 1 , wherein the camera body, scope, and cannula are configured to be removeably connected from one another.

17. The system of claim 1 , wherein the cannula comprises a cannula rotation guide on a proximal end of the cannula configured to rotate the cannula relative to the camera body.

18. The system of claim 17 , wherein the cannula rotation guide is configured to rotate the cannula and the scope when the portion of the scope is inserted into the lumen of the cannula.

19. The system of claim 17 , wherein the cannula rotation guide is configured to be positioned immediately distal the camera body when the scope and cannula are connected to the camera body.

20. The system of claim 1 , wherein a diameter of the cannula tapers from a proximal end of the cannula towards a distal end of the cannula.

21. The system of claim 1 , wherein a distal end of the cannula comprises a rounded tip.

22. The system of claim 21 , wherein a portion of the rounded tip is configured to wrap around a portion of a distal end of the scope when the portion of the scope is inserted into the lumen of the cannula.

23. The system of claim 22 , wherein the portion of the rounded tip is configured to wrap around a portion of the distal end of the scope without compromising or blocking illumination.

24. The system of claim 1 , wherein the proximal end of the camera body is configured to be communicatively coupled to a data cable or wirelessly, communicatively coupled to a computer.

25. The system of claim 1 , wherein the proximal end of the camera body is configured to be electrically coupled to a power cable or wirelessly, electrically coupled to a power source.

26. The system of claim 1 , wherein the scope and camera are configured to be wirelessly, electrically coupled to one another.

27. The system of claim 25 , wherein the scope and camera are configured to be wirelessly, electrically coupled to one another via inductive coupling.
