Robotic surgical system with illumination device to indicate mounting assembly installation condition

A method of operating a surgical system comprising a surgical robot comprising a robotic arm including a first mounting portion and an illumination device, a sterile barrier assembly being releasably attachable to the first mounting portion, a second mounting portion associated with a surgical component and being releasably attachable to the first mounting portion via the sterile barrier assembly, the second mounting portion comprising a tensioner movable from a first position to a second position to urge the second mounting portion towards the first mounting portion in response to movement of the tensioner towards the second position, and one or more controllers coupled to one or more sensors and the illumination device, the method comprising the one or more controllers:

• detecting, using the one or more sensors, a first condition wherein the second mounting portion is attached to the first mounting portion via the sterile barrier assembly and the tensioner is in the first position;
• controlling the illumination device to be in a first state to indicate the first condition;
• detecting, using the one or more sensors, a second condition wherein the second mounting portion is attached to the first mounting portion via the sterile barrier assembly and the tensioner is in the second position;
• and
• controlling the illumination device to be in a second state to indicate the second condition.

A surgical robotic system comprising:

• a robotic arm comprising a plurality of links and joints and including a first mounting portion coupled to a distal end of the robotic arm, wherein the first mounting portion is configured to releasably receive a sterile barrier assembly and a second mounting portion associated with a surgical component, the second mounting portion being releasably attachable to the first mounting portion via the sterile barrier assembly, the second mounting portion comprising a tensioner movable from a first position to a second position to urge the second mounting portion towards the first mounting portion in response to movement of the tensioner towards the second position, and wherein the robotic arm comprises an illumination device;
• and
• one or more controllers coupled to the illumination device and to one or more sensors and configured to:
• detect, using the one or more sensors, a first condition wherein the second mounting portion is attached to the first mounting portion via the sterile barrier assembly and the tensioner is in the first position;
• control the illumination device to be in a first state to indicate the first condition;
• detect, using the one or more sensors, a second condition wherein the second mounting portion is attached to the first mounting portion via the sterile barrier assembly and the tensioner is in the second position;
• and
• control the illumination device to be in a second state to indicate the second condition.
