Abstract
An electrolyte fluid purging electrosurgical device for use with an electrode holder connected to an electrical power source and to a source of a non-electrically conductive fluid and a method of use are disclosed. The fluid purging electrosurgical device enables electrosurgery at a surgical site where an area proximate the surgical site is surrounded by an electrically conductive fluid such as saline irrigation fluids, body fluids, certain injectables and the like. The fluid purging electrosurgical device comprises an electrode shaft with an electrode shaft connector electrically connecting a first end of the electrode shaft to an electrode holder. An insulating material provides electrical insulation between a second end of the electrode shaft and the electrode holder. The insulating material is positioned on the electrode shaft to expose a portion of the second end of the electrode shaft to define an electrode tip to provide electrical current to the surgical site. A duct means is connected to the source of the non-electrically conductive fluid and extends along the electrode shaft to deliver the non-electrically conductive fluid to a region immediately proximate the electrode tip to displace the electrically conductive fluid at the position of the electrode tip in the surgical site to enable electrosurgical treatment thereat.
