Monopolar plasma coagulation radial antenna tip design

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 defines an aperture extending parallel to the longitudinal axis;
• and
• an electrode extending through the inner volume and in contact with the applicator tip, the electrode comprising an open channel provided with an electrode tip at a distal end,
• wherein the electrode tip is received within the hollow inner volume of the shaft and within the aperture of the applicator tip to define a gas flow channel defined by the electrode and the elongate shaft and by the electrode and the applicator tip, the gas flow channel extending parallel to the longitudinal axis within the elongate shaft and extending radially outwards with respect to the longitudinal axis within the applicator tip.
