TREATMENT SYSTEM

摘要

A treatment system includes a treatment instrument that has a pair of freely openable/closable holding sections for applying thermal energy generated by a heat generation section to a living tissue LT held between the holding sections, a signal output section that supplies an alternating current drive signal to the heat generation section, a setting section that sets a target temperature of the heat generation section, a signal detection section that detects a current and a voltage of the drive signal, a control section that controls a temperature of the heat generation section by adjusting power of the drive signal, a signal extraction section that extracts a direct current component from the drive signal detected by the signal detection section and a fault detection section that detects a precursory phenomenon of a fault of the heat generation section based on the extracted signal extracted by the signal extraction section.

1. A treatment system comprising:
a treatment instrument that has a first holding section including a first heat generation section and a second holding section including a second heat generation section, and applies thermal energy to a living tissue held between the first holding section and the second holding section; a signal output section that supplies alternating current drive signals respectively to the first heat generation section and the second heat generation section; a signal detection section that detects the drive signals; a signal extraction section that extracts direct current components respectively from the drive signals of the first heat generation section and the second heat generation section detected by the signal detection section as extracted signals; a fault detection section that detects a precursory phenomenon of a fault of the first heat generation section or the second heat generation section when either any one of the extracted signals increases; and a control section that performs control, when the fault detection section detects the precursory phenomenon of the first heat generation section, so as to reduce power of the drive signal supplied to the first heat generation section and increase power of the drive signal supplied to the second heat generation section or performs control, when the fault detection section detects the precursory phenomenon of the second heat generation section, so as to reduce power of the drive signal supplied to the second heat generation section and increase power of the drive signal supplied to the first heat generation section.
