Electrosurgical unit (ESU) footswitches provide hands‑free, precise control over energy delivery during surgical procedures. Designed for reliability, safety, and intuitive use, these footswitches are available in configurations tailored to monopolar, bipolar, and vessel‑sealing functions.
Monopolar Footswitches
Monopolar footswitches typically feature a dual‑pedal design, allowing seamless switching between cutting and coagulation modes without returning to the generator.
Key Features
-
Colour‑coded pedals for safety — often yellow for Cut and blue for Coagulation
-
Controls the active electrode circuit, directing current through the patient to a grounding pad
-
Supports multiple modes including pure cut, blended cut, desiccation, and fulguration
-
Compatible with a wide range of monopolar instruments
Bipolar Footswitches
Bipolar footswitches are generally single‑pedal units, as both active and return electrodes are integrated into the bipolar instrument (e.g., forceps).
Key Features
-
Single‑pedal activation, often blue to indicate coagulation
-
Enables precise tissue grasping and coagulation with minimal thermal spread
-
Ideal for microsurgery, neurosurgery, ophthalmology, and delicate soft‑tissue work
-
Available in specialised versions for bipolar resection, particularly in urology
Vessel‑Sealing Footswitches
Designed for advanced bipolar or vessel‑sealing systems, these footswitches support instruments capable of sealing vessels.
Key Features
-
Dedicated Seal function for vessel fusion and tissue management
-
Works with reusable or disposable vessel‑sealing handpieces
-
Often paired with generators featuring intelligent tissue monitoring to prevent charring and reduce thermal spread
-
Provides reliable “seal and cut” performance for high‑efficiency surgical workflows
Compatibility & Safety
Modern ESU footswitches are engineered for broad compatibility and safe operation.
Highlights
-
Multi‑pedal units available for systems combining monopolar, bipolar, and sealing functions
-
Waterproof designs with audible activation tones for enhanced safety
- Some systems offer hand‑activated alternatives for specialised procedures
