Abstract

A surgical footswitch having elevated auxiliary buttons is provided. In particular embodiments, the surgical footswitch comprises a footswitch base, a treadle mounted on the footswitch base, a first primary button positioned on an upper surface of the footswitch base along a first lateral side of the treadle, a first auxiliary button housing positioned along a lateral side of the first primary button opposite the treadle, and a first auxiliary button mounted on an upper surface of the first auxiliary button housing, wherein an upper surface of the first auxiliary button is elevated in relation to an upper surface of the first primary button. In particular embodiments, the treadle is configured to activate a first function of a surgical console, the first primary button is configured to activate a second function of the surgical console, and the first auxiliary button is configured to activate a third function of the surgical console.

First claim

What is claimed is:

1. A surgical footswitch comprising:
a footswitch base;
a treadle mounted on the footswitch base, wherein the treadle comprises a heel cup directly attached to the treadle;
a first primary button positioned on an upper surface of the footswitch base along a first lateral side of the treadle and extending along a first length of the treadle;
a first auxiliary button housing positioned along a lateral side of the first primary button, opposite the first length of the treadle;
a first auxiliary button mounted on an upper surface of the first auxiliary button housing, wherein an upper surface of the first primary button is sloped upwards from a lower height adjacent the treadle to a higher height adjacent the first auxiliary button and an upper surface of the first auxiliary button is sloped upward from a lower height at a point on the first auxiliary button closest to the heel cup to a higher height at a point on the first auxiliary button most remote from the heel cup;
wherein the treadle is configured to activate a first function of a surgical console, the first primary button is configured to activate a second function of the surgical console, and the first auxiliary button is configured to activate a third function of the surgical console;
wherein the upper surface of the first auxiliary button is elevated in relation to the upper surface of the first primary button; and
wherein a proximal end of the first primary button is situated closer to the heel cup than to a distal end of the treadle most remote from the heel cup, wherein the proximal end of the first primary button is situated closer to the heel cup than a proximal end of the first auxiliary button is situated in relation to the heel cup, wherein the proximal end of the first auxiliary button is situated closer to the heel cup than to the distal end of the treadle most remote from the heel cup, and wherein a distal end of the first primary button is situated closer to the distal end of the treadle than a distal end of the first auxiliary button is situated in relation to the distal end of the treadle.

2. The surgical footswitch of claim 1 , further comprising:
a second primary button positioned on the upper surface of the footswitch base along a second lateral side of the treadle;
wherein the second primary button is configured to activate a fifth function of the surgical console; and
wherein the first lateral side of the treadle is opposite the second lateral side of the treadle.

3. The surgical footswitch of claim 2 , further comprising:
a second auxiliary button housing positioned along a lateral side of the second primary button, opposite the treadle; and
a second auxiliary button mounted on an upper surface of the second auxiliary button housing;
wherein the second auxiliary button is configured to activate a sixth function of the surgical console; and
wherein an upper surface of the second auxiliary button is elevated in relation to an upper surface of the second primary button.

4. The surgical footswitch of claim 1 , further comprising:
a second auxiliary button mounted on the upper surface of the first auxiliary button housing;
wherein the second auxiliary button is configured to activate a fifth function of the surgical console.

5. The surgical footswitch of claim 1 , wherein a difference in elevation between the upper surface of the first auxiliary button and the upper surface of the first primary button is less than 50 millimeters.

6. The surgical footswitch of claim 1 , wherein a difference in elevation between the upper surface of the first auxiliary button and the upper surface of the first primary button is between 10 millimeters and 50 millimeters.

7. The surgical footswitch of claim 1 , wherein the first primary button is positioned such that a user may activate the first primary button by depressing the first primary button.

8. The surgical footswitch of claim 1 , wherein the first auxiliary button is positioned such that a user may activate the first auxiliary button by depressing the first auxiliary button.

9. The surgical footswitch of claim 1 , wherein the first auxiliary button housing is integrated into the footswitch base.

10. The surgical footswitch of claim 1 , wherein at least one of the first primary button, the second primary button, the first auxiliary button, and the second auxiliary button is configured to provide feedback upon activation via at least one of a resistance to depression, a vibration, a sound indicator, and a visual indicator.

11. A surgical footswitch comprising:
a footswitch base;
a treadle mounted on the footswitch base, wherein the treadle comprises a heel cup directly attached to the treadle;
a first primary button positioned on an upper surface of the footswitch base along a first lateral side of the treadle and extending along a first length of the treadle;
a second primary button positioned on the upper surface of the footswitch base along a second lateral side of the treadle;
a first auxiliary button housing positioned along a lateral side of the first primary button, opposite the first length of the treadle;
a first auxiliary button mounted on an upper surface of the first auxiliary button housing, wherein an upper surface of the first primary button is sloped upwards from a lower height adjacent the treadle to a higher height adjacent the first auxiliary button and an upper surface of the first auxiliary button is sloped upward from a lower height at a point on the first auxiliary button closest to the heel cup to a higher height at a point on the first auxiliary button most remote from the heel cup;
a second auxiliary button housing positioned along a lateral side of the second primary button, opposite the treadle;
a second auxiliary button mounted on an upper surface of the second auxiliary button housing;
wherein the treadle is configured to activate a first function of a surgical console, the first primary button is configured to activate a second function of the surgical console, the second primary button is configured to activate a third function of the surgical console, the first auxiliary button is configured to activate a fourth function of the surgical console, and the second auxiliary button is configured to activate a fifth function of the surgical console;
wherein the upper surface of the first auxiliary button is elevated in relation to the upper surface of the first primary button, wherein a proximal end of the first primary button is situated closer to the heel cup than a proximal end of the first auxiliary button is situated in relation to the heel cup, and wherein a distal end of the first primary button is situated closer to a distal end of the treadle than a distal end of the first auxiliary button is situated in relation to the distal end of the treadle;
wherein an upper surface of the second auxiliary button is elevated in relation to an upper surface of the second primary button, wherein a proximal end of the second primary button is situated closer to the heel cup than a proximal end of the second auxiliary button is situated in relation to the heel cup, and wherein a distal end of the second primary button is situated closer to a distal end of the treadle than a distal end of the second auxiliary button is situated in relation to the distal end of the treadle; and
wherein the proximal end of the first primary button is situated closer to the heel cup than to a distal end of the treadle most remote from the heel cup, and the proximal end of the first auxiliary button is situated closer to the heel cup than to the distal end of the treadle most remote from the heel cup.
