Electrosurgical system and method for sterilizing chronic wound tissue

摘要

An electrosurgical method for sterilizing chronic wound tissue, comprising: positioning an active electrode in proximity to the chronic wound tissue; delivering an electrically conductive fluid proximate the active electrode; and applying a high frequency voltage between the active electrode and a return electrode in the presence of the electrically conductive liquid sufficient to generate an ionized vapor layer at the active electrode, wherein the ionized vapor layer sterilizes at least a portion of the chronic wound tissue.

1. An electrosurgical method of treating a chronic wound tissue comprising:
positioning an active electrode in proximity to the chronic wound tissue, wherein the chronic wound tissue comprises a wound bed, at least a portion of which comprises necrotic tissue; delivering an electrically conductive fluid proximate the active electrode; and applying a high frequency voltage between the active electrode and a return electrode in the presence of the electrically conductive fluid sufficient to generate an ionized vapor layer at the active electrode; removing at least a portion of the necrotic tissue in a substantially non-thermal manner by application of the ionized vapor layer to the chronic wound tissue, wherein the step of removing further comprises; sterilizing at least a portion of the wound bed while applying the ionized vapor layer; and preparing a uniform tissue surface more conducive to wound healing.
