1. A monopolar plasma coagulation applicator comprising:
an elongate shaft extending from a proximal end to a distal end thereof, and defining therein a hollow inner volume and a longitudinal axis of the applicator;
an applicator tip mounted on the distal end of the elongate shaft, wherein the applicator tip comprises a plurality of apertures extending parallel to the longitudinal axis; and
an electrode extending through the inner volume and in contact with the applicator tip, the electrode comprising a plurality of open channels, each of the plurality of open channels being provided with an electrode tip at a distal end,
wherein each electrode tip is received within the hollow inner volume of the shaft and within a respective aperture of the applicator tip to define a respective gas flow channel defined by the electrode and the elongate shaft and by the electrode and the applicator tip,
wherein each respective gas flow channel extends parallel to the longitudinal axis within the elongate shaft, and
wherein each electrode tip extends radially outward with respect to the longitudinal axis to an outermost surface of the applicator tip, so that the respective gas flow channel extends radially outwards with respect to the longitudinal axis within the applicator tip.
