摘要： 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.

摘要： A method and a measurement apparatus are provided for determining the transition impedance between two electrode parts of a subdivided neutral electrode used in high-frequency surgery. These makes it possible for the purely capacitive component of the transition impedance to be measured. For this purpose a resonant-frequency shift is measured, which occurs when a basic resonant circuit is expanded to an expanded resonant circuit by incorporating the two electrode parts into it in parallel. In particular, in order to determine the basic resonant frequency of the basic resonant circuit and/or the sample resonant frequency of the expanded resonant circuit, the phase shift between current and voltage is measured and the frequency is adjusted until current and voltage are in phase.

摘要： The invention relates to an electrosurgical instrument for coagulating and/or cutting biological tissue, which can be manufactured easily and economically, wherein a surgical intervention is to be carried out easily and reliably with the instrument. For this purpose, the instrument comprises the following: two linked branches which can be moved toward one another, gripping devices at a proximal region of the branches or of the instrument for bringing the branches together, electrode parts at a distal region of the branches or of the instrument for grasping tissue and for conducting an HF current through the tissue, current feed devices for feeding the HF current to the electrode parts from an HF generator, a switching device for activating the HF current with the branches brought together, at least one spacing element to form a defined minimum spacing between the electrode parts, at least one elastically deformable element, which is arranged at one of the branches or the gripping devices such that, on closing the branches and reaching the minimum spacing, at least one region of the gripping devices can be moved further in the proximal region for actuating the switching device. The instrument can also be carried out as a shaft instrument, wherein at least one electrode part is movable through a shaft in its extension direction.
