Robotic surgical systems and robotic arm carts thereof

A surgical robotic assembly, comprising:

• a surgical robotic arm configured to support a surgical instrument;
• a processor in communication with the surgical robotic arm;
• and
• a surgical cart including:
• cart base;
• a support column extending vertically from the cart base and configured to support the surgical robotic arm;
• at least one caster coupled to the base;
• a brake pedal operably coupled to the base and configured to move between a pedal first position, in which the at least one caster is unlocked, and a pedal second position, in which the at least one caster is locked;
• a latching solenoid coupled to the base adjacent the brake pedal and in communication with the processor, wherein the latching solenoid, in response to a command from the processor, is configured to move a plunger between a plunger first position, in which the plunger does not prevent the brake pedal from moving from the pedal second position to the pedal first position, and a plunger second position, in which the plunger prevents the brake pedal from moving from the pedal second position to the pedal first position;
• and
• a sensor system coupled to the surgical cart, the sensor system in communication with the processor and configured to determine a distance between the surgical instrument and a patient,
• wherein the processor is configured to inhibit commanding the latching solenoid to move the plunger from the plunger second position to the plunger first position unless the distance is at least a predetermined safe distance.

A surgical cart for supporting a robotic arm, comprising:

• a base;
• at least one caster coupled to the base;
• a brake pedal operably coupled to the at least one caster and configured to move between a pedal first position, in which the at least one caster is unlocked, and a pedal second position, in which the at least one caster is locked;
• a latching solenoid coupled to the base, wherein the latching solenoid is configured to move a plunger between a plunger first position, in which the plunger does not prevent the brake pedal from moving from the pedal second position to the pedal first position, and a plunger second position, in which the plunger prevents the brake pedal from moving from the pedal second position to the pedal first position, wherein the plunger includes a pin configured to protrude through an opening of a housing structure disposed adjacent an arm of the brake pedal such that the pin blocks actuation of the brake pedal when the plunger is in the plunger second position;
• a manual control knob attached to the plunger such that the plunger is manually movable from the plunger second position to the plunger first position, wherein the manual control knob extends out of the housing structure such that the pin of the plunger is manually actuatable;
• and
• a cover detachably coupled to the base and configured to conceal the manual control knob, wherein the cover is configured such that, prior to manually actuating the manual control knob to move the plunger to the first plunger position, a clinician must remove the cover to access the manual control knob, the manual control knob providing a manual override in an emergency situation comprising a power loss.
