Thermocoagulation/cutting device

A thermocoagulation/cutting device comprising:

• a first jaw;
• an exothermic part provided on a surface of the first jaw along a longitudinal direction of the first jaw;
• a first current supply portion projecting integrally from the exothermic part on a distal end side of the first jaw;
• a second current supply portion projecting integrally from the exothermic part on a proximal end side of the first jaw;
• a third current supply portion projecting integrally from the exothermic part at a position between the first current supply portion and the second current supply portion;
• and
• a controller electrically connected to the first current supply portion, the second current supply portion and the third current supply portion, the controller being configured to cause an electric current to flow, in the exothermic part, between:
• (A) the first current supply portion and the second current supply portion, (B) the first current supply portion and the third current supply portion, or (C) the second current supply portion and the third current supply portion, wherein:
• a dimension of the exothermic part in a direction crossing a longitudinal direction of the exothermic part is less than:
• (i) a dimension of the first current supply portion in a direction crossing a longitudinal direction of the first current supply portion, (ii) a dimension of the second current supply portion in a direction crossing a longitudinal direction of the second current supply portion, and (iii) a dimension of the third current supply portion in a direction crossing a longitudinal direction of the third current supply portion.
