Patent abstract

The invention relates to a neutral electrode for HF surgery and to an electrically conductive gel. The neutral electrode comprises at least one electrically conductive section that can be brought into contact with a section of a patient's body. In order to enable the contact resistance to be reduced in a simple and economical manner, in particular in cases of problematic skin and/or tissue conditions, the neutral electrode comprises circulation-promoting means that enhance blood flow through the section of the body that is in contact with this electrode section. The invention also relates to a conductive gel for application of a neutral electrode to a section of a patient's body that contains capsaicin or similar means for promoting circulation.
