Haptic footswitch treadle
First Claim
Patent Images
1. A haptic footswitch for communication with a health care provider using an ophthalmic microsurgical system, comprising:
- a body;
a treadle configured to rotate relative to the body, the treadle including a haptic surface and a treadle base, the treadle base pivotably coupled to the body;
at least one suspension element coupling the treadle base and the haptic surface a distance apart from each other, wherein movement of the suspension element in a first direction moves the haptic surface in the first direction; and
at least one actuator actuatable to displace the haptic surface relative to the treadle base in a manner providing haptic feedback to the health care provider.

Abstract
A haptic footswitch treadle for use in microsurgical systems is disclosed. The haptic footswitch treadle includes a haptic surface coupled to a pivotable treadle base and configured to convey vibratory haptic feedback to a surgeon. The haptic footswitch includes a positional sensor coupled to the treadle base and suspension elements and actuators positioned between the haptic surface and the treadle base. The actuators are configured to move the suspension elements and the haptic surface based on command signals generated by haptic software applications in response to data from the positional sensor.

13. An ophthalmic microsurgical system, comprising:
-
a footswitch comprising;
a body;a treadle configured to rotate relative to the body, the treadle comprising; a haptic surface, and a treadle base, the treadle base pivotably coupled to the body, the haptic surface supported by and spaced a distance apart from the treadle base and displaceable relative to the treadle base; at least one suspension element, the suspension element coupled to the haptic surface and separating the haptic surface and the treadle base; at least one actuator actuatable to displace the haptic surface relative to the treadle base in a manner providing haptic feedback to the health care provider, wherein movement of the actuator causes movement of the haptic surface relative to the treadle base; and a sensor configured to sense the rotational position of the treadle relative to the body and convey data representative of the position of the treadle; and a handpiece having a plurality of functions selectively activated based on the rotational position of the treadle. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of providing haptic feedback by a footswitch to a health care provider during a surgical procedure, comprising:
- detecting a position of a treadle relative to a body of the footswitch with a sensor, the detected position corresponding to surgical mode controllable by the footswitch;
generating an actuator command signal based on the detected position of the treadle, the actuator command signal having a haptic feedback profile corresponding to the detected position; actuating an actuator in accordance with the actuator command signal to displace a haptic surface of the treadle relative to a treadle base of the treadle to signal to the healthcare provider that the treadle is in the detected position; wherein actuating an actuator to displace a haptic surface comprises displacing a suspension element coupled to the haptic surface and disposed between the haptic surface and the treadle base, the suspension element displacing the haptic surface relative to the treadle base. - View Dependent Claims (20)
