Abstract
An electrosurgical dissection apparatus is disclosed, and includes a thermally insulating body, a thermally conductive insert, at least one active electrode, and at least one return electrode. The at least one active electrode is disposed on the thermally conductive insert, and the at least one return electrode is spaced from the at least one active electrode by a portion of the thermally insulating body. The thermally conductive insert is configured to cauterize tissue dissected by radiofrequency energy passing from the at least one active electrode to the at least one return electrode.
