Abstract

In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.

Claims

1. An aspiration tubing, comprising:

a high compliant section;

a low compliant section;

a transition section coupling the high compliant section to the low compliant section;

wherein the high compliant section is configured to couple to a handpiece; and

wherein the low compliant section is configured to couple to a surgical console.

2. The aspiration tubing of claim 1,

wherein the handpiece is an ophthalmic handpiece;

and

wherein surgical console is an ophthalmic surgical console.

3. The aspiration tubing of claim 1, wherein the transition section comprises a connector.

4. The aspiration tubing of claim 1, wherein the transition section comprises a length of tubing that is continuous with the high compliant section and the low compliant section.

5. The aspiration tubing of claim 4, wherein a durometer of the transition section changes over the length of the transition section.

6. The aspiration tubing of claim 1, wherein the high compliant section further comprises at least one of ribs, rings, a spine, a sleeve, or a sock to decrease compliance of the high compliant section.

7. The aspiration tubing of claim 1, wherein the high compliant section has a durometer approximately in a range of 50 ShoreA to 70 ShoreA.

8. The aspiration tubing of claim 1, wherein the low compliant section has a durometer approximately in a range of 80 ShoreA to 100 ShoreA.

9. The aspiration tubing of claim 1, wherein the high compliant section has a length approximately in a range of 1 to 2 inches.

10. The aspiration tubing of claim 1, wherein the low compliant section has a length approximately in a range of 50 to 90 inches.

11. A system, comprising:

an ophthalmic surgical console;

a handpiece coupled to the surgical console by an aspiration tubing and an irrigation tubing;

wherein the aspiration tubing, comprises;

a high compliant section configured to couple to the ophthalmic handpiece;

a low compliant section configured to couple to the ophthalmic surgical console; and

a transition section coupling the high compliant section to the low compliant section.

12. The system of claim 11, wherein the transition section of the aspiration tubing comprises a connector.

13. The system of claim 11, wherein the transition section of the aspiration tubing comprises a length of tubing that is continuous with the high compliant section and the low compliant section.

14. The system of claim 13, wherein a durometer of the transition section changes over the length of the transition section.

15. The system of claim 11, wherein the high compliant section of the aspiration tubing further comprises at least one of ribs, rings, a spine, a sleeve, or a sock to decrease compliance of the high compliant section.

16. The system of claim 11, wherein the high compliant section of the aspiration tubing has a durometer approximately in a range of 50 ShoreA to 70 ShoreA.

17. The system of claim 11, wherein the low compliant section of the aspiration tubing has a durometer approximately in 80 ShoreA to 100 ShoreA.

18. The system of claim 11, wherein the high compliant section of the aspiration tubing has a length approximately in a range of 1 to 2 inches.

19. The system of claim 11, wherein the low compliant section of the aspiration tubing has a length approximately in a range of 50 to 90 inches.
