Abstract:
Unintended current flow or plasma discharge has been observed in known illuminated electrosurgical devices having a metallic tubular heat sink surrounding a conductive electrode and an illumination element, and having a distal outer edge that abuts against the light emitting element. An insulating, shielding or other isolating element that prevents or discourages unintended plasma formation between the distal outer edge and nearby patient tissue can reduce the potential for tissue damage to a patient or injury to a surgeon.

Claim (Index 30):
An electrosurgical device comprising:\n a) a handle; b) a conductive electrode supported by the handle and having a tip for tissue cutting or tissue cauterizing; c) an illumination element having a light source, an optical waveguide, and a light emitting element illuminating the electrode tip; d) a metallic tubular heat sink that can be slidably extended from the handle, the heat sink:\n surrounding at least part of the conductive electrode and at least part of the illumination element, \n having a length, \n having a distal outer edge that abuts the light emitting element, and \n having a breakdown voltage between the distal outer edge and nearby patient tissue when the device is used to dispense radiofrequency energy through the electrode tip; and \n e) a plastic insulating sleeve or plastic insulating collar that is placed over at least a portion of the illumination element and over the distal outer edge of the heat sink, and that increases the heat sink breakdown voltage.
