    摘要： An arrangement, configured for electrical charge equalization after the generation of one or more stimulation current pulses, containing a bridge circuit, switching elements, a bridge branch between two legs of the bridge circuit, into which a load resistance can be introduced, and at least one power source for generating at least one stimulation current pulse, which is connected to the legs of the bridge circuit in such a way that it enables an electrical current via one leg through the bridge branch and furthermore through a leg connected to the other end of the bridge branch with corresponding switch position. The arrangement includes a capacitive element in the bridge branch for generating a current for electrical charge equalization for current introduced by one or more stimulation current pulses and is configured such that, between one or more stimulation current pulses and a discharge of the capacitive element via one or more stimulation electrodes, a delay time window is maintained, which is used for measuring electrical physiological signals induced as a reaction to the stimulation current pulse or pulses; and related subjects of the invention.

    摘要： The present invention relates to a suction instrument, more particularly a bipolar mapping suction instrument, for surgical purposes and to a system for suctioning fluids and tissue and for monitoring nerve tissue. The suction instrument comprises a cannula unit, which comprises an electrically conductive outer cannula tube, an electrically conductive inner cannula tube, and insulation. The electrically conductive inner cannula tube is electrically connected to a first pole of the bipolar electrical connection of the second interface. The electrically conductive inner cannula tube is arranged concentrically in the outer cannula tube which optionally can be insulated from the exterior. The electrically conductive inner cannula tube is mechanically connected to the handpiece and/or the first interface. The electrically conductive outer cannula tube is electrically connected to a second pole of the bipolar electrical connection of the second interface. The insulation is concentrically arranged between the outer cannula tube and the inner cannula tube. The insulation is configured to fully electrically isolate the outer cannula tube and the inner cannula tube in relation to one another.

    摘要： An arrangement for electrical charge equalization after generation of stimulation current pulse(s), containing a bridge circuit, switching elements, a bridge branch between two legs of the bridge circuit, into which a load resistance is introducible, and a power source for generating a stimulation current pulse, connected to the legs of the bridge circuit that enables an electrical current via one leg through the bridge branch and through a leg connected to the other end of the bridge branch with corresponding switch position. A capacitive element is in the bridge branch for generating a current for electrical charge equalization for current introduced by stimulation current pulse(s) and is configured such that, between one or more stimulation current pulses and a discharge of the capacitive element via stimulation electrode(s), a delay time window is maintained, which is used for measuring electrical physiological signals induced as a reaction to the stimulation current pulse(s).
