Abstract

A hand-controllable switch for remote control of an electrosurgical instrument is comprised of an elongated hollow body composed of an electrically insulative material with an electrical conductor tube positioned therein, a blade member inserted lengthwise through a bore in connected relation to the conductor tube, and electrical leads terminating in longitudinally spaced relation to one another so that in contacting the conductor tube they are operative to establish distinct electrical power levels. The body is composed of a resilient material in which is resiliently mounted one or more annular switch members which are depressible under hand or finger pressure at any point on their circumferences to effect closure with the electrical conductor tube.
