Abstract
An electrosurgical instrument including a probe tube for transporting fluid, at least one electrode for devitalizing tissue, and at least one conducting foil electrical lead arranged along the longitudinal axis of the probe tube for providing a high frequency (RF) voltage at the electrode. A method of producing an electrosurgical instrument, including applying a conductive foil to a probe tube that extends along the longitudinal axis of the probe tube, and providing at least one electrode on the probe tube, wherein the electrode electrically connects to the conductive foil.
Claims17
An electrosurgical instrument comprising:
- a probe tube having a longitudinal axis for transporting fluid;
- at least one electrode for devitalizing tissue;
- and
- at least one electrical lead for providing an RF voltage to the electrode,
- wherein the electrical lead comprises a conductive foil arranged along the longitudinal axis of the probe tube, and
- wherein the conductive foil is arranged in a helical structure around the probe tube along the longitudinal axis of the probe tube.
A method of manufacturing an electrosurgical instrument, the method comprising:
- applying a conductive foil to a probe tube, the probe tube defining a longitudinal axis, wherein the conductive foil extends along the longitudinal axis of the probe tube;
- providing a first electrode on the probe tube, wherein the first electrode is electrically connected to the conductive foil;
- and
- providing at least one connection on a proximal first end of the probe tube, the at least one connection providing electrical connection to the conductive foil,
- wherein the conductive foil is arranged in a helical structure around the probe tube along the longitudinal axis of the probe tube.
