Abstract

An ocular surgical apparatus is provided, including a surgical control device such as a foot pedal configured to be employed to control at least one ocular surgical parameter, and a controller configured to receive a series of values from the surgical control device and evaluate the series of values provided from the surgical control device, the series of values provided using a buffer comprising a detection area and an exclusion area. Presence of a desired value in the detection area and an absence of a contrary indication in the exclusion area is determined by the controller to indicate a switch associated with the surgical control device is requested by a user of the surgical control device.

First claim

What is claimed is:

1. An ocular surgical apparatus comprising:
a user-manipulated surgical interface that controls at least one ocular surgical parameter and outputs a series of values;
a buffer that receives the series of values from the user-manipulated surgical interface and comprises a detection area and an exclusion area; and
a controller that evaluates the series of values sequentially as the values are provided from the user-manipulated surgical interface;
wherein presence of a desired value in the detection area and an absence of a contrary indication in the exclusion area is determined by the controller to indicate a switch associated with the user-manipulated surgical interface is requested by a user of the surgical interface such that the controller implements a function associated with the switch.

2. The ocular surgical apparatus of claim 1 , wherein the user-manipulated surgical control interface comprises a foot pedal.

3. The ocular surgical apparatus of claim 1 , wherein the buffer further comprises a secondary limitation area and the presence of an unacceptable value in the secondary limitation area indicates no switching is requested by the user of the user-manipulated surgical interface.

4. The ocular surgical apparatus of claim 1 , wherein the buffer further comprises samples taken at discrete points in time and contents of the buffer progress in a first in, first out (FIFO) manner.

5. The ocular surgical apparatus of claim 1 , wherein the controller indicating the switch is requested causes the controller to provide a switching request to a component in the ocular surgical apparatus.

6. The ocular surgical apparatus of claim 1 , wherein presence of invalid data in any buffer region indicates no switching is requested by the user of the user-manipulated surgical interface.

7. The ocular surgical device of claim 1 , wherein user initiation of a desired movement causes an indication to be provided to the buffer and after a predetermined period of time the indication progresses to the detection area.

8. The ocular surgical apparatus of claim 1 , wherein the user-manipulated surgical interface allows the user to select from a plurality of predetermined input options that control the at least one ocular surgical parameter.

9. An ocular surgical apparatus comprising:
a user-manipulated surgical interface that controls at least one ocular surgical parameter and outputs a series of values;
a buffer that receives the series of values from the user-manipulated surgical interface and comprises a detection area and an exclusion area; and
a controller
that evaluates the series of values sequentially as the values are provided from the user-manipulated surgical interface, and
controls an attribute of the ocular surgical apparatus when the series of values indicates a user desires a switch of the attribute based on user input received from the user-manipulated surgical interface;
wherein presence of a desired value in the detection area and an absence of a contrary indication in the exclusion area is determined by the controller to indicate a switch associated with the user-manipulated surgical interface is requested by the user of the surgical interface such that the controller implements a function associated with the switch.

10. The ocular surgical apparatus of claim 9 , wherein the user-manipulated surgical interface comprises a foot pedal.

11. The ocular surgical apparatus of claim 9 , wherein the buffer further comprises a secondary limitation area and the presence of an unacceptable value in the secondary limitation area indicates no switching is requested by the user of the user-manipulated surgical interface.

12. The ocular surgical apparatus of claim 9 , wherein the buffer further comprises samples taken at discrete points in time and contents of the buffer progress in a first in, first out (FIFO) manner.

13. The ocular surgical apparatus of claim 9 , wherein presence of invalid data in any buffer region indicates no switching is requested by the user of the user-manipulated surgical interface.

14. The ocular surgical apparatus of claim 9 , wherein user initiation of a desired movement causes an indication to be provided to the buffer and after a predetermined period of time the indication progresses to the detection area.

15. The ocular surgical apparatus of claim 1 , wherein the user-manipulated surgical interface allows the user to select from a plurality of predetermined input options that control the at least one ocular surgical parameter.
