Abstract

In various embodiments, a surgical console may include a sensor strip with sensor strip sensors (e.g., field effect or capacitive sensors) offset vertically and configured to receive an input from a user corresponding to a vertical height of a patient'"'"'s eyes relative to the surgical console. The surgical console may use the input from the sensor strip to determine a patient eye level (PEL) relative to a surgical console component and then use the PEL and the at least one component in controlling operation of at least one of a source of irrigation or a source of aspiration during an ophthalmic procedure. The surgical console may further include a plurality of visual indicators positioned relative to at least two of the plurality of sensor strip sensors and configured to be illuminated to correspond to a sensor detecting the touch input.

Claims

1. A surgical console, comprising:

at least one component configured to be used during an ophthalmic procedure;

a sensor strip comprising a plurality of sensor strip sensors, wherein at least two of the plurality of sensor strip sensors are offset vertically and wherein the sensor strip is configured to receive an input from a user, through the sensor strip, that corresponds to a vertical height of a patient'"'"'s eyes relative to the surgical console;

wherein the surgical console is configured to use the input to determine a patient eye level (PEL) relative to the at least one component;

wherein the surgical console is configured to use the PEL and the at least one component in controlling operation of at least one of a source of irrigation or a source of aspiration during the ophthalmic surgical procedure.

2. The surgical console of claim 1, wherein the sensor strip sensors comprise field effect switch or capacitive sensors.

3. The surgical console of claim 1, wherein the PEL is a perpendicular distance between the patient'"'"'s eyes and a line, parallel to the ground/floor, that intersects the at least one component of the surgical console.

4. The surgical console of claim 1, further comprising a plurality of visual indicators, wherein at least two of the plurality of visual indicators are positioned relative to at least two of the plurality of sensor strip sensors.

5. The surgical console of claim 4, wherein the surgical console is configured to illuminate at least one of the plurality of visual indicators that corresponds to a sensor detecting the touch input.

6. The surgical console of claim 1, wherein the component of the surgical console is an aspiration pressure sensor.

7. The surgical console of claim 1, wherein the sensor strip sensors are arranged along a curved line on the surgical console.

8. The surgical console of claim 1, wherein the PEL is used by the surgical console to control an aspiration pump speed to increase/decrease an operating aspiration pressure to be within a desired range.

9. The surgical console of claim 1, wherein the PEL is used by the surgical console to raise/lower the irrigation bottle to increase/decrease the irrigation pressure provided through a hand piece coupled to the surgical console to be within a desired range.

10. The surgical console of claim 1, further comprising a light source configured to project a horizontal light ray at the vertical height corresponding to the sensor strip input received from the user.

11. A surgical console, comprising:

an aspiration pump;

an aspiration sensor configured to detect an aspiration pressure in a line coupled to the aspiration pump;

a sensor strip comprising a plurality of field effect switch or capacitive sensors, wherein at least two of the plurality of sensors are offset vertically and wherein the sensor strip is configured to receive an input from a user, through the sensor strip, that corresponds to a vertical height of a patient'"'"'s eyes relative to the surgical console;

a plurality of visual indicators, wherein at least two of the plurality of visual indicators are positioned relative to the at least two of the plurality of sensor strip sensors and wherein the surgical console is configured to illuminate at least one of the plurality of visual indicators that corresponds to a sensor strip sensor detecting the user input;

wherein the surgical console is configured to use the input to determine a patient eye level (PEL) relative to the aspiration sensor of the surgical console;

wherein the surgical console is configured to use the PEL and information from the aspiration sensor to control operation of the aspiration pump to obtain a desired aspiration pressure at the patient'"'"'s eyes through a hand piece coupled to the console.

12. The surgical console of claim 11, wherein the PEL is a perpendicular distance between the patient'"'"'s eyes and a line, parallel to the ground/floor, that intersects the at least one component of the surgical console.

13. The surgical console of claim 11, wherein the visual indicators overlap the sensor strip sensors.

14. The surgical console of claim 11, wherein the sensor strip sensors and the visual indicators are arranged along a curved line on the surgical console.

15. The surgical console of claim 11, wherein the PEL is further used by the surgical console to raise/lower the irrigation bottle to increase/decrease the irrigation pressure provided through a hand piece coupled to the surgical console to be within a desired range.

16. The surgical console of claim 11, further comprising a light source configured to project a horizontal light ray at the vertical height corresponding to the sensor strip input received from the user.
