Abstract:
1. A medical plasma generator comprising: a gas supply tube for supplying a gas required for the generation of plasma; an internal electrode having a tube shape, a joined part joined to the end of the gas supply tube, and an extended part extended from the joined part, wherein the extended part has a smaller diameter than the joined part, thereby allowing the gas to jet out with an increased speed when the gas passes through the internal electrode, and wherein a high voltage is applied to the internal electrode; a glass tube enclosing the extended part of the internal electrode and protruding from the internal electrode; and a ground electrode formed on an outer surface of a protruding part of the glass tube, wherein interaction between the ground electrode and the internal electrode leads to ionization and discharge of the gas passing through the internal electrode, thereby generating plasma.
