The electric operation instrument which includes the neutral electrode device and the neutral electrode device which corresponds, contact media, and use of the latent heat accumulation body in order to cool the electrode

摘要

Stationary risk of the patient who suffers from the burn with the neutral electrode at the time of operating which uses unipolar HF, exists. As for aforementioned problem, manner is devised many, it has originated in the fact that relatively high HF electric current, long time is applied with those. It solves this invention, by designing the neutral electrode device which is used in order to apply HF electric current aforementioned problem vis-a-vis the body tissue. Until aforementioned the neutral electrode device which is improved includes the latent heat accumulation body in order at least to absorb one heat, depends, is accumulated the heat energy which can be discharged the peak of heat, safely, it makes that it accumulates at least temporarily possible.
