The Citadel 180 delivers tissue feedback technology that automatically adjusts power output based on real-time impedance changes, reducing thermal damage and improving cut quality across different tissue types. Unlike basic ESUs that operate at fixed settings, this unit continuously monitors and modifies delivery to match what you’re actually cutting.

Patient return electrode monitoring adds a safety layer that’s worth noting for risk management, automatically detecting poor pad contact or detachment before burns occur. The self-diagnostic protocols run checks on both the unit and connected accessories, catching performance issues before they affect procedures. Bottom line: fewer surgical delays and better documentation for your biomedical team.

Waterproof foot pedals hold up in busy ORs, and the optional modules (argon beam, smoke evacuation, ultrasonic aspiration) let you build out capabilities without adding separate units to your equipment roster.
