INDUCTIVELY COUPLED ELECTROSURGICAL TROCAR

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 toconnect 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.
