Electrosurgical Instrument With Blade Profile For Reduced Tissue Damage
First Claim
1. An electrosurgical instrument for conveying electrosurgical power to tissue to achieve a predetermined electrosurgical effect, comprising:
- an electrosurgical blade having a leading edge and a trailing edge, the electrosurgical blade comprising an electrically conductive element, and an insulation layer overlaying the conductive element except at a conductor edge forming a primary reaction region solely along at least a portion of the leading edge; and
a handle electrically coupled to the electrically conductive element.

Abstract
An electrosurgical instrument includes a body having at least one conductive element that is surrounded by an insulation layer except at a conductor edge portion of the conductive element. The profile of the electrosurgical instrument is configured to concentrate the flow of electrosurgical energy in a concentration region to facilitate starting or initiating the electrosurgical process. The profile of the electrosurgical instrument is further configured to prevent excessive delivery of electrosurgical energy to reduce or eliminate the production of smoke and eschar and reduce tissue damage.
