Abstract

An apparatus and method for controlling fluid flow provided by an apparatus to a patient'"'"'s eye during a surgical procedure. The method includes automatically adjusting an irrigation fluid source to a predetermined height during the surgical procedure using the apparatus, receiving a request either that the irrigation fluid source be moved to a different height from the predetermined height or that a manual adjustment mode be entered, and ceasing automatic adjusting and requiring manual adjustment of the height of the irrigation fluid source until the surgical procedure is completed or an indication received to resume automatic height adjustment of the irrigation fluid source. As an alternative, fluid flow rate or intraocular pressure may be maintained, and the design may include making adjustments to default values in other modes based on the adjustment made.

Claims

1. A method for controlling fluid flow provided by an apparatus to a patient'"'"'s eye during a surgical procedure, comprising:

automatically adjusting an irrigation fluid source to a predetermined height during the surgical procedure using the apparatus;

receiving, at the apparatus, a request that the irrigation fluid source be moved to a different height from the predetermined height; and

ceasing automatic adjusting and requiring manual adjustment of irrigation fluid source height until the surgical procedure is completed or an indication received to resume automatic height adjustment of the irrigation fluid source.

2. The method of claim 1, wherein the receiving, at the apparatus, the request comprises receiving a request from a user for the different height.

3. The method of claim 1, wherein the receiving, at the apparatus, the request comprises receiving a request to enter a manual mode.

4. The method of claim 1, wherein receiving, at the apparatus, the request comprises receiving a request to maintain one selected from the group consisting of intraocular pressure (IOP) and fluid flow rate, and the method further comprises determining a height adjustment based on IOP or fluid flow rate received.

5. The method of claim 1, further comprising, after receiving the request, adjusting a default height related value for at least one other mode based on a difference between the predetermined height and the different height.

6. The method of claim 5, wherein the default height related value consists of one from a group comprising irrigation fluid source height, intraocular pressure (IOP) and fluid flow rate.

7. The method of claim 1, wherein the receiving, at the apparatus, the request comprises receiving the request as a result of the apparatus changing modes from a first operating mode indicating a first desired height to a second operating mode indicating a second desired height differing from the first desired height.

8. The method of claim 1, wherein the apparatus comprises a phacoemulsification machine and the surgical procedure comprises an ocular surgical procedure.

9. The method of claim 1, wherein the indication to resume automatic adjustment comprises a user entered indication provided via a user interface, wherein the user interface communicates with the apparatus.

10. The method of claim 2, wherein receiving the indication occurs via a user interface provided at the apparatus.

11. The method of claim 1, wherein the predetermined height comprises a first default height provided for a first mode of the apparatus and the different height comprises a second default height provided for a second mode of the apparatus.

12. An apparatus configured to provide fluid from an irrigation fluid source during a surgical procedure, comprising:

a retractable tubular arrangement configured to maintain the irrigation fluid source at a desired height; and

a controller configured to automatically adjust the irrigation fluid source using the retractable tubular arrangement to a predetermined height during the surgical procedure using the apparatus;

wherein the apparatus is configured to receive an indication that a different height from the predetermined height is requested, and upon receiving the indication, the apparatus commands the controller to cease automatic operation and requires manual adjustment of irrigation fluid source height until the surgical procedure is completed or an indication received to resume automatic adjustment of height of the irrigation fluid source.

13. The apparatus of claim 12, wherein the apparatus receives the indication from a user for the different height.

14. The apparatus of claim 12, wherein the apparatus receives the indication as a result of the apparatus changing modes from a first operating mode indicating a first desired height to a second operating mode indicating a second desired height differing from the first desired height.

15. The apparatus of claim 12, wherein the apparatus comprises a phacoemulsification machine and the surgical procedure comprises an ocular surgical procedure.

16. The apparatus of claim 12, wherein the indication to resume automatic adjustment comprises a user entered indication provided via a user interface, wherein the user interface communicates with the apparatus.

17. The apparatus of claim 13, further comprising a user interface configured to receive the indication.

18. The apparatus of claim 12, wherein the predetermined height comprises a first default height provided for a first mode of the apparatus and the different height comprises a second default height provided for a second mode of the apparatus.

19. A method for controlling fluid flow to a patient'"'"'s eye using an ocular surgical device during an ocular surgical procedure, comprising:

causing the ocular surgical device to position an irrigation fluid source at at least one desired height without operator intervention during the ocular surgical procedure;

requesting the ocular surgical device move the irrigation fluid source to a different height from at least one desired height; and

ceasing causing the ocular surgical device to position the irrigation fluid source without operator intervention and requiring operator adjustment of irrigation fluid source height until the surgical procedure is completed or an indication received to resume height adjustment without operator intervention of the irrigation fluid source.

20. The method of claim 19, wherein the requesting comprises a user providing a request to the ocular surgical device for the different height.

21. The method of claim 19, wherein the requesting comprises the ocular surgical device providing an internal indication upon changing modes from a first operating mode indicating a first desired height to a second operating mode indicating a second desired height differing from the first desired height.

22. The method of claim 19, wherein the ocular surgical device comprises a phacoemulsification machine.

23. The method of claim 19, wherein the indication to resume height adjustment without operator intervention comprises a user entered indication provided via a user interface, wherein the user interface in communication with the ocular surgical device.

24. The method of claim 20, wherein the requesting occurs via a user interface provided at the ocular surgical device.

25. The method of claim 19, wherein the predetermined height comprises a first default height provided for a first mode of the ocular surgical device and the different height comprises a second default height provided for a second mode of the ocular surgical device.

26. A method for controlling fluid flow provided by an apparatus to a patient'"'"'s eye during a surgical procedure, comprising:

automatically adjusting an irrigation fluid source to a predetermined height during the surgical procedure using the apparatus;

receiving, at the apparatus, a request that a manual adjustment mode be entered; and

ceasing automatic adjusting of the irrigation fluid source until the surgical procedure is completed or an indication received to resume automatic height adjustment of the irrigation fluid source.
