In the present invention, a surgical trocar is adapted to capacitively couple electrosurgical energy to specially adapted cordless electrosurgical instruments. In one embodiment of the present invention, an electrosurgical trocar includes a cannula, a capacitive electrosurgical adapter and a locking connector adapted to connect the cannula to the capacitive electrosurgical adapter. The cannula is an elongated tube which may be inserted into a body cavity, duct or vessel. The electrosurgical adapter includes a housing with an elongated central aperture, an adapter proximal capacitor plate and an adapter distal capacitor plate positioned in and extending axially along the elongated aperture, first and second electrical conductors, first and second external conductors, a compression mechanism, an outer housing and an electrical cord.
