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. A method for use in an ocular surgical apparatus, the method comprising:
receiving, by a buffer of the ocular surgical apparatus, a series of values from a user-manipulated surgical interface, the buffer comprising a detection area and an exclusion area;
sequentially evaluating, by a controller of the ocular surgical apparatus, the series of values as provided from the user-manipulated surgical interface;
controlling at least one ocular surgical parameter of the ocular surgical apparatus based on contents of the buffer;
wherein a presence of a desired value in the detection area and an absence of a contrary indication in the exclusion area indicate a switch associated with the user-manipulated surgical interface is requested by the user-manipulated surgical interface such that the controller controls the at least one ocular surgical parameter with respect to the switch.

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

3. The method 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-manipulated surgical interface.

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

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

6. The method 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.

7. The method of claim 1 , wherein the switch comprises a signal indicating a switch selection.

8. The method of claim 7 , wherein the series of values comprise individual and discrete states of the buffer that indicate valid and invalid states for a validation of a receipt of the switch selection.

9. The method of claim 1 , wherein the user-manipulated surgical interface enables selection from a plurality of predetermined input options that control the at least one ocular surgical parameter.
