How to Choose an Electrosurgical Unit: Power, Modes, Safety

Electrosurgery · DS.Med editorial

The ESU price spread is tenfold, and the difference is not marketing: it is power, mode set and intelligence. Map your interventions first — the right generator follows.

Power: match the tissue

  • 150 W — outpatient rooms, dressing rooms, minor surgery
  • 200 W — operating rooms of day hospitals, gynecology, proctology
  • 300 W — general surgery and urology on dense, moist tissue
  • 400 W — large ORs, two surgeons, long interventions

Modes: what your procedures require

Blend cutting and spray coagulation are the baseline. Bipolar autostart frees the pedal in microsurgery. Memory programs speed up recurring operations. Flagship functions — intelligent polypectomy, TURP in liquid medium, Seal vessel ligation up to 7 mm and argon support — replace separate devices.

Safety systems

Return-electrode monitoring, tissue impedance control and audible activation are non-negotiable. Check also the documentation package: registration certificates and service availability decide tenders as often as specifications.

Frequently asked questions

Which ESU fits an outpatient surgery office?
A 150–200 W unit with blend cutting and bipolar coagulation, e.g. DS.Surg 150 or 200S.
What do memory programs give in practice?
The team recalls proven mode-and-power settings in one press instead of re-dialing before every operation — fewer errors, faster turnover.
Is one flagship better than two mid-range units?
For a multi-OR department two generators give redundancy; a single high-tech OR benefits more from one flagship with Seal and TURP.
