Abstract:
1. A high-frequency coagulation apparatus comprising: a tubular body having an opening portion which is formed in an end portion of the tubular body, and is open in a predetermined direction; a high-frequency electric current generation section for generating a high-frequency electric current; a first electrode provided within the opening portion of the tubular body; a second electrode provided on the end portion of the tubular body; a third electrode provided on the tubular body and apart from the second electrode; a fourth electrode provided separate from the tubular body to contact a living body; energizing means for electrically connecting the first to fourth electrodes to the high-frequency electric current generation section so that the high-frequency electric current flows between the first and fourth electrodes, and between the second and third electrodes; a fluid supply section for supplying to the tubular body a fluid which is to be discharged from the opening portion of the tubular body, and is capable of transmitting the high-frequency electric current to be made to flow between the first and fourth electrodes; and a controller for controlling supplying of the fluid from the fluid supply section to the tubular body, and also supplying of the high-frequency electric current from the high-frequency electric current generation section to the first to fourth electrodes.
