Title:
ELECTRIC SURGERY APPARATUS AND METHOD FOR CONTROLLING ELECTRIC SURGERY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/044354
Kind Code:
A1
Abstract:
A high-frequency ablation power supply (2) is an electric surgery apparatus for bonding biological tissues.  The electric surgery apparatus includes a high-frequency power supplying section for supplying a high-frequency power which is applied to biological tissues, a detecting section for detecting the voltage and current of the high-frequency power outputted from the high-frequency power supplying section, an impedance calculating section for calculating from the voltage and current values detected by the detecting section the impedance between a pair of electrodes (3a) which holds the biological tissues and to which the high-frequency power is supplied, and a control section (18) for controlling the supply and substantial stop of the high-frequency power from the high-frequency power supplying section depending on whether or not the impedance calculated by the impedance calculating section has exceeded a predetermined value twice.
