Electrosurgical blade
First Claim
Patent Images
1. An electrosurgical blade for conveying electrosurgical power to tissue to achieve a predetermined electrosurgical effect, comprising:
- an electrically conductive element having a first section and a first tapered section terminating at a conductor edge;
an insulation layer having a second tapered section overlaying the entire conductive element which tapers against a side of the first tapered section to expose the conductor edge at a distalmost end of the blade, forming a primary reaction region, wherein the conductor edge at a distalmost end of the electrically conductive element is flush against the insulation layer; and
an electrical coupling surface for electrically coupling the electrically conductive element to a handle.

Abstract
An electrosurgical blade includes a conductive element that is surrounded by an insulation layer except at a conductor edge portion of the conductive element. The conductor edge portion and insulation layer each have unique geometric shapes and composition of the parts to reduce or eliminate the production of smoke and eschar and reduce tissue damage. The outer profile of the insulation layer and conductive element are configured to facilitate the flow of electrosurgical decomposition products away from the conductor edge where they are formed.
