ABSTRACT:
An electrosurgical device to generate a plasma stream and method to perform endoscopic or laparoscopic surgery within a patient's body comprising an electrosurgical generator coupled to a electrical power source to supply power to the electrosurgical device and a plasma generator including an electrode operatively coupled to the electrosurgical generator to receive electrical energy therefrom and concentrically disposed within an inner noble gas conduit to form a plasma channel coupled to a noble gas source to feed noble gas to the inner noble gas conduit and an outer electronegative gas conduit disposed in surrounding coaxial relation relative to the inner noble gas conduit to cooperatively form an electronegative gas channel therebetween coupled to a gas source to feed electronegative gas to the electronegative gas channel or an outer aspiration conduit disposed in surrounding coaxial relation relative to the inner noble gas conduit to cooperatively form an aspiration channel therebetween coupled to a negative pressure source such that the electrode heats the noble gas to at least partially ionize the noble gas to generate the plasma stream to be directed to the surgical site to perform the surgical procedure while the electronegative gas sustains the plasma stream at the surgical site and dilutes the noble gas adjacent the surgical site or the negative pressure source removes fluid and solid debris from the surgical site respectively.
