Abstract

A surgical footswitch for controlling a surgical instrument. The surgical footswitch includes a base. A treadle is rotatably coupled to the base to operate the surgical instrument. A foot guard is also rotatably coupled to the base. A blocking portion of the foot guard is configured to prevent physical access to the treadle in a lateral direction in a first position and permit access to the treadle in a lateral direction in a second position. A floor engagement portion of the foot guard engages a floor surface when the blocking portion is in the first position. The floor engagement portion is spaced from the floor surface when the blocking portion is in the second position. The floor engagement portion permits physical access to the treadle in a longitudinal direction when the blocking portion is in both the first position and the second position.

Dependent claims

A surgical footswitch for controlling a surgical instrument, the surgical footswitch comprising:

a base having a bottom surface for resting on a floor surface and a top surface opposite the bottom surface;
a treadle disposed above the top surface of the base, the treadle comprising a treadle body having a first end rotatably coupled to the base and a second end opposite the first end, and the treadle body rotatable about a treadle axis;
and
a foot guard comprising,
a blocking portion coupled to the base and movable to a first position in which physical access to the treadle body in a lateral direction is prevented and a second position in which physical access to the treadle body in the lateral direction is permitted, and
a floor engagement portion extending from the blocking portion, the floor engagement portion configured to engage the floor surface when the blocking portion is in the first position, and the floor engagement portion configured to be spaced from the floor surface when the blocking portion is in the second position, and the floor engagement portion configured to permit physical access to the treadle body in a longitudinal direction when the blocking portion is in both the first position and the second position.
