摘要： 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 preferably disposable cannula and a preservable supply electrode assembly. The cannula has a tubular body that projects axially from a preferably pointed distal end for piercing tissue to a proximal end engaged to a first coupling assembly of the cannula. The body carries a first contact exposed directly to the nerve tissue and connected electrically to a terminal of the first coupling assembly. 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 the tool is in an operating state. The second coupling assembly carries a terminal that abuts the first coupling assembly when the coupling assemblies are mated. Preferably the supply electrode carries a temperature sensor for temperature measurement of the targeted tissue and processing by the control unit. Preferably, the electrode assembly also includes a stylet having a rod that fits into the through-bore of the body when the supply electrode assembly is removed and the tool is in a tissue penetrating state.

摘要： 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.
