Surtron 80, 120 and 160 W electrosurgical unit

The Surtron 80, 120 and 160 are radiofrequency electrosurgical units designed for minor surgery in the clinic: they cut and coagulate soft tissue with an active electrode mounted on the handpiece, while the current returns to the unit through a neutral plate placed under the patient. The manufacturer's manual intends them for dermatology, dentistry, emergency surgery and A&E, and restricts their use to doctors trained in high-frequency electrosurgery.

The three versions share the same cabinet, controls and accessories: only the maximum power changes, which in pure cut ranges from 80 to 160 W. On the panel you choose between four monopolar currents (CUT, BLEND, FORCED COAG and SOFT COAG); with the optional adapter you can also connect bipolar forceps. Levels appear on numeric displays and when switched back on the unit recalls the last setting.

Safety relies on automatic checks: the neutral plate connection is monitored continuously and, with a split plate, so is its contact with the skin; a self-test runs at switch-on. Output is activated from the handpiece buttons or the footswitch, without taking your eyes off the operating field.
