Abstract
An electrosurgical system preferably used for denervation procedures of nerve tissue has a control unit and a pluggable electrode assembly. The electrode assembly has a disposable cannula and a preservable supply electrode assembly. The cannula has a tubular body that projects axially from a pointed distal end for piercing tissue to a proximal end engaged to a first coupling assembly of the cannula. The supply electrode assembly has a second coupling assembly and a supply electrode that projects axially and removably into a through-bore of the body when in an operating state. The first and second coupling assemblies are configured to releasably interlock to prevent clockwise and counterclockwise rotation of the supply electrode in the body.
