High-frequency coagulation apparatus
First Claim
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.

Abstract
A high-frequency coagulation apparatus according to the present invention comprises a controller for controlling supply of the fluid from a fluid supply section to a tubular body and controlling supply of the high-frequency electric current from a high-frequency electric current generation section to an electrode, wherein the controller has a first mode for supplying the high-frequency electric current from the high-frequency electric current generation section to the electrode and supplying the fluid from the fluid supply section to the tubular body, and a second mode for supplying the high-frequency electric current from the high-frequency electric current generation section to the electrode and interrupting supply of the fluid from the fluid supply section to the tubular body.
