Multi-Arm Telesurgical Indicator Using Color-Coded LEDs

The patent applies color changes by using multi-color LED indicators (red, yellow, green) to communicate different manipulator states. Each color represents specific information: red indicates faults or critical states, yellow indicates warnings or intermediate states, and green indicates normal operation. This color-coding system efficiently transmits complex status information through simple visual cues, improving communication without requiring complex display interfaces.

The patent applies segmentation by placing individual visual indicators on each manipulator assembly rather than using a centralized display. Each manipulator has its own indicator that independently communicates its specific state, allowing team members to quickly identify which manipulator requires attention. This segmented approach distributes the communication function across multiple simple units rather than one complex system.

The patent applies periodic action by using blinking or flashing indicator patterns to communicate different states or to draw attention to specific manipulators. Indicators can blink to indicate that a manipulator is selected, to alert team members to a status change, or to indicate waiting states. This temporal variation in the indicator output provides an intuitive way to convey information without adding more static indicators.

The patent uses distinct color meanings to reduce confusion: red universally signals problems or stop conditions, yellow signals caution or intermediate states, and green signals normal operation or go conditions. This standardized color-coding system leverages universally recognized visual cues, making the interface intuitive even with multiple indicators present.

The patent applies the extraction principle by removing the need for team members to verbally query or interrupt the surgeon to check manipulator status. The visual indicators continuously display manipulator states in the operating room, allowing team members to monitor system status independently without interrupting the surgical procedure. This extracts the monitoring function from the surgical workflow, maintaining reliability while minimizing interruptions.

The patent applies self-service by enabling team members to autonomously monitor manipulator status through the visual indicators without requiring interaction with the surgeon or system operator. The indicators provide continuous, real-time feedback about manipulator states, allowing the surgical team to self-monitor and self-manage the robotic system during procedures, reducing the need for interruptions.
