Monopolar hook electrode
A thin laparoscopic electrode, insulated except at its active hook-shaped (L- or J-shaped) tip, connected to a monopolar electrosurgical generator.
How it is used
Used to hook, lift and divide tissue with monopolar energy (simultaneous cutting and coagulation), particularly for dissecting Calot's triangle during laparoscopic cholecystectomy.
Clinical tip
Insulation defects or capacitive coupling can cause unintended thermal injury away from the visible tip; inspect the insulation and use the lowest effective power setting.
