    • 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.
    • 一种用于产生血浆流的电外科装置和在患者体内进行内窥镜或腹腔镜手术的方法,包括耦合到电源以向电外科装置供电的电外科发生器,以及等离子体发生器,其包括可操作地耦合到电外科发生器 以从其中接收电能并同心地设置在内部惰性气体导管内以形成耦合到惰性气体源的等离子体通道,以将稀有气体供给到内部惰性气体导管,以及外部电负极气体导管,其以相对于内部的内部 惰性气体管道,其协同地形成电气气体通道,其耦合到气体源以将电负性气体供给到电负性气体通道或相对于内部惰性气体导管设置成围绕同轴关系的外部吸入管道,以协同地形成其中的吸入通道 补偿剂耦合到负压源,使得电极加热惰性气体以至少部分地离子化惰性气体,以产生等离子体流,以引导到外科手术部位进行外科手术,而电负性气体维持等离子体流在 手术部位并稀释邻​​近手术部位的惰性气体,或负压源分别从手术部位移除流体和固体碎屑。
