Claim 0:
1. A treatment system comprising:
a first jaw;
a second jaw, the first jaw and the second jaw confirmed to grasp a living tissue;
a heater resistor provided on the first jaw, the heater resistor configured to generate heat by energization; and
a control device including:
a double bridge circuit having a detection resistor electrically connected to the heater resistor, the double bridge circuit configured to allow current to flow through the detection resistor when the detection resistor detects a difference between a resistance value of the heater resistor and a predetermined target resistance value,
a power supply voltage generator configured to generate a power supply voltage to be applied to the heater resistor and the double bridge circuit,
a controller configured to modulate the power supply voltage, and
a heater resistance detector configured to detect the current flowing through the detection resistor.
