PROBLEM TO BE SOLVED: To provide a means for correctly and reliably determining timing when the gripping and coagulation (hemostasis) of a treated part is shifted to its separation by using a multi-functional treatment device capable of performing the exfoliation, gripping, coagulation (hemostasis), and separation concerning a bipolar microwave treatment device.SOLUTION: A method and an apparatus for controlling a microwave surgical device are provided, by which the oscillation output of microwave is controlled by detecting the completion of coagulation (hemostasis) in a tissue through the use of the change of a DC electric resistance value since moisture is reduced in the tissue together with the rise of the temperature when the tissue of the treated part is heated and coagulated with the microwave.COPYRIGHT: (C)2009,JPO&INPIT【課題】双極式マイクロ波処置具において、処置部の剥離、把持、凝固(止血)及び切離が可能な多機能処置具を使用して処置部を把持、凝固(止血)から切離に移行する場合のタイミングを正確、確実に判定する手段を提供する。【解決手段】処置部位の組織をマイクロ波で加熱凝固時に組織の温度上昇と共に水分が減少し、直流電気抵抗値が変化するのを利用して、組織の凝固(止血)終了を検知させ、マイクロ波の発振出力を制御するマイクロ波手術装置の制御方法及び装置。【選択図】図1
