A laparoscopic surgical instrument which may be in the form of forceps or a cutter has, at the end of a hollow tube (10) for introduction through the body cavity wall, a housing (14A, 14B), a pair of pivotally mounted metallic jaws (12A, 12B), a reciprocable control rod (18) in the tube (10), and an actuator (16) secured to the control rod (18). The actuator (16) has a pair of guide grooves (16GG) which are oppositely inclined with respect to a longitudinal axis of the instrument, and each jaw has a lug (12F) which fits in a respective groove (16GG), the lugs (12F) being spaced from the jaw pivots so that reciprocation of the control rod (18) causes opening and closing of the jaws (12A, 12B).; The housing (14A, 14B) and the actuator (16) are electrically insulating and the jaw pivots are spaced apart to achieve electrical isolation of one jaw from the other, for applying a radio frequency voltage across the jaws (12A, 12B) for bipolar electrosurgery.
