Abstract

A system, method and apparatus for notifying a surgeon of an occlusion in an ocular surgical apparatus are disclosed herein. Through operation of a handpiece of the surgical apparatus, the handpiece may become blocked or occluded. An occlusion detector is configured to sense the occlusion in the handpiece, and an occlusion signal is generated. A control module is provided to send an occlusion warning signal to a foot pedal of the surgical apparatus, where a tactile notification is provided to a user of the apparatus that an occlusion has occurred.

First claim

What is claimed is:

1. A method of detecting an ocular occlusion, the method comprising:
providing at least one sensor communicatively coupled to a handpiece configured to transport irrigation fluid into a patient's eye and aspirate fluid from the patient's eye;
generating at least one signal from the at least one sensor in accordance with the detecting of a variance from a predetermined pressure in the handpiece; and
providing at least one notification in accordance with the at least one signal;
wherein the at least one signal has a first length indicative of a magnitude of the variance from a predetermined pressure, and
wherein the at least one notification is generated for a second length that is commensurate with the first length.

2. The method of claim 1 , wherein the at least one notification includes a tactile notification through a foot pedal communicatively coupled to the handpiece.

3. The method of claim 1 , wherein the magnitude of the variance from a predetermined pressure is measured in time.

4. The method of claim 1 , wherein the magnitude of the variance from a predetermined pressure is a measurement of pressure.

5. The method of claim 4 , wherein the measurement of pressure comprises a drop in pressure in the handpiece.

6. The method of claim 4 , wherein the measurement of pressure comprises a propagation of a pressure drop over a period of time.

7. The method of claim 1 , wherein the at least one notification is provided in a foot pedal comprising a treadle and a body housing, the treadle being rotatably coupled to the body housing.
