摘要:
Disclosed is an electro surgical device for use by a surgeon to perform coagulation procedures to damaged tissue and evacuation procedures to related fluids. In one embodiment, the device comprises a first electrode having a first open end, a second open end, an outside surface, and a channel extending from the first open end to the second open end. The device further comprises a second electrode having a first end, a second end, an inside surface, and an outside surface. The inside surface of the second electrode is encased about the outside surface of the first electrode and electrically isolated by an insulator. The device further comprises first and second terminal pins each having a first end connected to the first and second electrodes, respectively, and a second end adapted to engage with the electrical generator. The device further comprises a housing having a suction port and a terminal pin portion. The suction port comprises an inner portion in communication with the second end of the first electrode and an outside portion adapted to engage with the suction device. Upon activation of the suction device, the surgeon may cause fluid to evacuate into the first end of the first electrode, flow through the channel, and exit the suction port to the suction device. Upon activation of the electrical generator, the surgeon may cause an electrical potential to be generated at and between the first end of the first electrode and the first end of the second electrode.
