ELECTRODE DEVICE AND SCALP ELECTRODE Russian patent published in 2014 - IPC A61B5/448 

FIELD: electricity.

SUBSTANCE: electrode device comprises a scalp electrode and a driving tube. The scalp electrode comprises a cylindrical holder of the electrode. A helical wire electrode at one end of the holder is connected to the driving tube by a torque-limiting connection, which makes it possible for the driving tube to separate from the holder and continue rotation relative to the holder as the preset torque is achieved. The surface of the holder is equipped with facilities to connect to the end of the driving tube with the purpose of rotating the holder around the axis of rotation, which provides for a positive connection to transfer rotation until achievement of the threshold torque. The holder is equipped with a deflecting surface in the form of a guide for deflection of the driving tube in the axial direction from the end of the holder, at which there is a helical wire electrode, when the driving tube continues rotation after separation. The contact surface of the holder end for contact with a fruit is equipped with a groove stretching transversely in respect to the base of the helical wire electrode.

EFFECT: increased reliability of the electrode fixation for the prevention of its unscrewing during usage.
