This electrotome is designed for insertion through a trocar into a body cavity for laproscopic surgery, in particular, for resection of diseased tissue. The instrument comprises three coaxial components, a core rod, tubular conductor, and outer sheath, each with a handle, and a ribbon like cutting electrode. The cutting electrode is retained flat against the core rod for insertion and manipulation of the instrument adjacent to the tissue to be resected, and the electrode is extended into a bow for cutting. After extension and electrical heating, the electrotome is rotated in a clockwise or counterclockwise manner with simultaneous resection and cauterization of the tissue. The excised tissue can then be trapped between the electrode and core rod for removal from the body cavity.
