Abstract

Systems, devices, and methods of the present disclosure assist with management of tubes and hoses during surgical procedures. The systems, devices, and methods provide for the proper opening and closing of tubes to facilitate performance of steps in a surgical procedure. Systems, devices, and methods of the present disclosure control fluid delivery to and from a medical device, including devices for tissue processing and cleaning.

Claims

1. A tissue treatment system, comprising:

a processing container, including an exterior side wall, a top wall, and a bottom wall, wherein the exterior side wall, top wall, and bottom wall surround an interior volume for holding tissue; and

a filtering structure having a rigid frame and a mesh filter, wherein the filtering structure is disposed within the interior volume for processing tissue, wherein the rigid frame extends from the top wall to the bottom wall, and the mesh filter is supported by the rigid frame, wherein the filtering structure divides the interior volume into an inner chamber and an outer chamber, and wherein the filtering structure is sloped inwardly from the top wall to the bottom wall.

2. The tissue treatment system of claim 1, further comprising an extraction port in fluid communication with the inner chamber.

3. The tissue treatment system of claim 1, wherein the rigid frame comprises:

a first frame member attached to the top wall;

a second frame member attached to the bottom wall; and

at least one rib member connecting the first frame member to the second frame member.

4. The tissue treatment system of claim 3, wherein the rigid frame forms at least one window, wherein the mesh filter is mated within the at least one window and supported by the rigid frame.

5. The tissue treatment system of claim 3, wherein the first frame member includes a first diameter and the second frame member includes a second diameter, wherein the first diameter is greater than the second diameter.

6. The tissue treatment system of claim 1, further comprising a spring and needle gauge to indicate the mass of tissue present within the inner chamber of the system.

7. The tissue treatment system of claim 1, wherein the rigid frame is formed from a single piece of solid material.

8. The tissue treatment system of claim 1, further comprising a telescoping mixing paddle disposed within the inner chamber, wherein the telescoping mixing paddle comprises at least one blade at a first axial position and at least one blade at a second axial position different than the first axial position.

9. The tissue treatment system of claim 8, wherein the blades at different axial positions can rotate with respect to one another.

10. The tissue treatment system of claim 8, wherein the telescoping mixing paddle is convertible to a piston form.

11. The tissue treatment system of claim 1, further comprising a mixing and auger system including a central shaft having at least one mixing blade and an auger, wherein the central shaft extends from the top wall and into the inner chamber of the filtering structure.

12. The tissue treatment system of claim 1, wherein the mesh filter is formed from a single piece of material.

13. The tissue treatment system of claim 1, wherein the mesh filter comprises cut-through holes, and wherein the first frame member comprises a boss feature to engage with the cut-through holes to position the mesh filter.

14. The tissue treatment system of claim 1, wherein the mesh filter has holes configured to fit the rigid frame such that the holes of the mesh filter align with solid portions of the rigid frame.

15. The tissue treatment system of claim 1, further comprising a plurality of tube-restriction devices.

16. The tissue treatment system of claim 15, wherein the plurality of tube-restriction devices comprises press-down buttons.

17. The tissue treatment system of claim 15, wherein the plurality of tube-restriction devices comprises snap-down panels.

18. The tissue treatment system of claim 1, further comprising a base attached to the bottom wall.

19. The tissue treatment system of claim 18, further comprising an extraction port passing through a portion of the bottom wall and in fluid communication with the inner chamber.

20. The tissue treatment system of claim 1, further comprising a flip-out handle that is rotatable in a first position and rests in a groove in a second position.
