摘要： In the present invention, a surgical trocar is adapted to inductively couple electrosurgical energy to specially adapted cordless electrosurgical instruments. In one embodiment of the present invention, an electrosurgical trocar includes a cannula, an inductive electrosurgical adapter and a locking connector adapted to connect the cannula to the inductive electrosurgical adapter. The cannula is an elongated tube which may be inserted into a body cavity, duct or vessel. The inductive electrosurgical adapter includes a housing with an elongated central aperture, a primary inductor coil positioned around and extending axially along the elongated aperture, first and second inductor leads, first and second conductors, an outer housing and an electrical cord.

摘要： A safety-shielded trocar having an obturator with a linear cutting edge surface defining a base width substantially less than the diameter of the safety shield is disclosed. When the trocar is inserted through tissue, the tissue dilates from the width of the linear incision to accommodate the size of the safety shield of the trocar, thus making it possible to provide an access opening greater than the incisional width made by the linear cutting edge surface of the obturator. In a preferred embodiment, the safety shield has a shield tip region which is asymmetric to facilitate the dilation of the tissue as the trocar is inserted.
