Abstract:
1. A treatment system comprising: a treatment instrument: (i) comprising: a first holding section including a first heat generation section, and a second holding section including a second heat generation section, and (ii) configured to apply thermal energy to a living tissue held between the first holding section and the second holding section; a signal output section configured to supply a first alternating current drive signal to the first heat generation section in order to heat the first heat generation section, and supply a second alternating current drive signal to the second heat generation section in order to heat the second heat generation section; a signal detection section configured to detect the first and second drive signals; a signal extraction section configured to extract a direct current component superimposed on the first drive signal as a first extracted signal on the basis of the first drive signal, and extract a direct current component superimposed on the second drive signal as a second extracted signal on the basis of the second drive signal; a fault detection section configured to: (1) detect the first extracted signal as a precursory phenomenon of a fault of the first heat generation section, when the first extracted signal exceeds a predetermined threshold, and (2) detect the second extracted signal as a precursory phenomenon of a fault of the second heat generation section, when the second extracted signal exceeds the predetermined threshold; and a control section configured to control the signal output section on the basis of a result of detection of the fault detection section, wherein
