Locking casters for surgical systems

A caster assembly for use with a surgical console, the caster assembly comprising:

• a plurality of caster wheels;
• a plurality of lock members corresponding to the plurality of caster wheels, each lock member comprising a pivot component, an extension portion, and a brake portion coupled to the pivot component and the extension portion, the brake portion being pivotably mounted via the pivot component to permit the brake portion to pivot relative to a respective caster wheel, the extension portion extending from the brake portion in a direction opposite the pivot component;
• and
• a movable lock plate coupled to the extension portion of each of the plurality of lock members, wherein the movable lock plate is translatable to pivot the brake portion of each of the plurality of lock members about the respective pivot component between a locked position in which a respective brake portion engages with the respective caster wheel and an unlocked position in which the respective brake portion is disengaged with the respective caster wheel.

A caster assembly for use with a surgical console, the caster assembly comprising:

• a caster comprising:
• a caster support coupled to the surgical console;
• a wheel support rotatably coupled to the caster support, wherein the wheel support selectively swivels relative to the caster support;
• a direction locking mechanism comprising a keyway, wherein the keyway is rotatable between a direction locked position coupling the caster support and the wheel support together to prevent swivel of the wheel support relative to the caster support and a direction unlocked position spacing apart the caster support and the wheel support to permit swivel of the wheel support relative to the caster support;
• and
• a caster wheel rotatably coupled to the wheel support;
• a key extending between a first end and a second end, wherein the first end extends through the keyway of the direction locking mechanism of the caster;
• a linkage coupled to the key, wherein the linkage is spaced apart from the keyway;
• and
• a pedal rotatably coupled to the linkage about a linkage pivot component, wherein the pedal is movable to rotate the linkage about the linkage pivot to rotate the key (i) to rotate the keyway toward the direction locked position, and (ii) to rotate the keyway toward the direction unlocked position.

A caster assembly for use with a surgical console, the caster assembly comprising:

• a first and second caster, each caster comprising:
• a caster support coupled to the surgical console;
• a wheel support rotatably coupled to the caster support, wherein the wheel support selectively swivels relative to the caster support;
• a direction locking mechanism comprising a keyway, wherein the keyway is rotatable between a direction locked position coupling the caster support and the wheel support together to prevent swivel of the wheel support relative to the caster support and a direction unlocked position spacing apart the caster support and the wheel support to permit swivel of the wheel support relative to the caster support;
• and
• a caster wheel rotatably coupled to the wheel support;
• a key extending between a first end and a second end, wherein the first end extends through the keyway of the direction locking mechanism of the first caster and the second end extends through the keyway of the direction locking mechanism of the second caster;
• a first pedal rotatably coupled to the key, wherein the first pedal is movable to rotate the key (i) to rotate the keyway toward the direction locked position, and (ii) to rotate the keyway toward the direction unlocked position;
• a first and second lock member corresponding to the caster wheel of the first and second caster, each lock member comprising a pivot component, an extension portion, and a brake portion coupled to the pivot component and the extension portion, the brake portion being pivotably mounted via the pivot component to permit the brake portion to pivot relative to the caster, the extension portion extending from the brake portion in a direction opposite the pivot component;
• and
• a second pedal coupled to the extension portion of the first and second lock member, wherein movement of the second pedal pivots the brake portion of the first and second lock members about the respective pivot component between a locked position in which a respective brake portion engages with a respective caster wheel and an unlocked position in which the respective brake portion is disengaged with the respective caster wheel.
