Abstract: A treatment system 1 includes a pair of openable/closable holding sections 10 that has a heat generation section 20 for applying thermal energy and holds a living tissue, a signal output section 31 that supplies a drive signal to the heat generation section 20, a setting section 32 that sets a target temperature of the heat generation section 20, a signal detection section 33 that detects a current and a voltage of the drive signal, a control section 34 that controls a temperature of the heat generation section 20 by adjusting a power of the drive signal, a signal extraction section 35 that extracts a signal of a predetermined frequency band from the drive signal detected by the signal detection section 33, and a fault detection section 36 that detects a precursory phenomenon of a fault of the heat generation section 20 on the basis of an extracted signal extracted by the signal extraction section 35.
