Abstract

The disclosure relates to an ophthalmosurgical system that includes a first irrigation fluid source. The system also includes a first irrigation fluid line connected to the first irrigation fluid source at a first end and open at a second end. The system further includes an aspiration fluid line, by which a fluid can be removed from an ocular lens. In addition, the system includes a suction pump, to which the aspiration fluid line is connected, and a second irrigation fluid source, to which a second irrigation fluid line is connected. The second irrigation fluid line is connected to the first irrigation fluid line at a coupling site. The system also includes a first valve, which is disposed between the first end of the first irrigation fluid line and the coupling site, and a second valve, which is disposed between the second irrigation fluid source and the coupling site.

Claims

1. A system, comprising:

a first irrigation fluid source;

a first irrigation fluid line connected to the first irrigation fluid source at a first end of the first irrigation fluid line, the first irrigation fluid line having a second end opposite the first end, the second end of the first irrigation fluid line being open so that a first irrigation fluid can be transported from the first irrigation fluid source and out of the second end of the first irrigation line;

an aspiration fluid line configured to be in fluid communication with the second end of the first irrigation fluid line;

a suction pump to which the aspiration fluid line is connected;

a second irrigation fluid source to which a second irrigation fluid line is connected, the second irrigation fluid line being connected to the first irrigation fluid line at a coupling site so that both the first and second irrigation fluid sources are simultaneously in fluid communication with the first irrigation fluid line so that a second irrigation fluid can be supplied into the first irrigation fluid line from the second irrigation fluid line at the same time as the first irrigation fluid can be supplied into the first irrigation fluid line from the first irrigation fluid source, a fluid pressure from the first irrigation fluid source being capable of being built up using the second irrigation fluid source, the fluid pressure being higher than can be achieved with the first irrigation fluid source alone;

a first valve between the first end of the first irrigation fluid line and the coupling site; and

a second valve between the second irrigation fluid source and the coupling site,

wherein the system is an ophthalmosurgical system.

2. The system of claim 1, wherein the suction pump comprises a piston pump, the piston pump comprises a controllable drive and a cylinder, and the piston pump is configured to hold an aspirated fluid in the cylinder.

3. The system of claim 1, further comprising a third valve, wherein the third valve is in the aspiration fluid line.

4. The system of claim 1, wherein the second irrigation fluid source comprises a piston pump, the piston pump comprises a controllable drive and a piston, and the piston pump is configured to dispense the second irrigation fluid contained in the piston into the second irrigation fluid line.

5. The system of claim 1, further comprising a third valve, wherein the third valve is in the first irrigation fluid line between the coupling site and the second end of the first irrigation fluid line.

6. The system of claim 1, further comprising:

a third irrigation fluid line;

a third irrigation fluid source connected to the aspiration fluid line via the third irrigation fluid line; and

a third valve, the third valve being in the third irrigation fluid line.

7. The system of claim 6, wherein the third irrigation fluid source comprises a piston pump, the piston pump comprises a controllable drive and the piston, and the piston pump is configured to dispense a third irrigation fluid contained in the piston into the aspiration fluid line via the third irrigation fluid.

8. The system of claim 7, further comprising:

a filling line that connects the third irrigation fluid source to the first irrigation fluid source; and

a fourth valve, the fourth valve being in the filling line.

9. The system of claim 6, further comprising:

a filling line that connects the third irrigation fluid source to the first irrigation fluid source; and

a fourth valve, the fourth valve being in the filling line.

10. The system of claim 1, further comprising a third valve, wherein the third valve is in the aspiration fluid line, the suction pump comprises a first piston pump, the first piston pump comprises a controllable drive and a cylinder, and the first piston pump is configured to hold an aspirated fluid in the cylinder.

11. The system of claim 10, wherein the second irrigation fluid source comprises a second piston pump, the second piston pump comprises a controllable drive and a piston, and the second piston pump is configured to dispense the second irrigation fluid contained in the piston into the second irrigation fluid line.

12. The system of claim 11, further comprising a fourth valve, wherein the fourth valve is in the first irrigation fluid line between the coupling site and the second end of the first irrigation fluid line.

13. The system of claim 12, further comprising:

a third irrigation fluid line;

a third irrigation fluid source connected to the aspiration fluid line via the third irrigation fluid line; and

a fifth valve, the fifth valve being in the third irrigation fluid line.

14. The system of claim 1, further comprising a third valve, wherein the third valve is in the aspiration fluid line, the second irrigation fluid source comprises a piston pump, the piston pump comprises a controllable drive and a piston, and the piston pump is configured to dispense the second irrigation fluid contained in the piston into the second irrigation fluid line.

15. The system of claim 14, further comprising a fourth valve, wherein the fourth valve is in the first irrigation fluid line between the coupling site and the second end of the first irrigation fluid line.

16. The system of claim 15, further comprising:

a third irrigation fluid line;

a third irrigation fluid source connected to the aspiration fluid line via the third irrigation fluid line; and

a fifth valve, the fifth valve being in the third irrigation fluid line.

17. The system of claim 1, further comprising a third valve, wherein the third valve is in the first irrigation fluid line between the coupling site and the second end of the first irrigation fluid line, the second irrigation fluid source comprises a piston pump, the piston pump comprises a controllable drive in the piston, and the piston pump is configured to dispense the second irrigation fluid contained in the piston into the second irrigation fluid line.

18. The system of claim 17, further comprising:

a third irrigation fluid line;

a third irrigation fluid source connected to the aspiration fluid line via the third irrigation fluid line; and

a fourth valve, the fourth valve being in the third irrigation fluid line.

19. The system of claim 1, wherein the system is configured so that, during use, the first and second irrigation fluids are provided to an ocular lens via the second end in the first irrigation fluid line, and a fluid is removed from the ocular lens via the aspiration fluid line.

20. The system of claim 1, wherein:

the second valve has a first position and a second position;
