Title (EN) PLASMA-GENERATING DEVICE, PLASMA SURGICAL DEVICE AND USE OF PLASMA SURGICAL DEVICE
(FR) DISPOSITIF GENERATEUR DE PLASMA, DISPOSITIF CHIRURGICAL AU PLASMA ET UTILISATION D'UN DISPOSITIF CHIRURGICAL AU PLASMA
Abstract:
(EN) The present invention relates to a plasma-generating device, comprising an anode, a cathode and a plasma channel which in its longitudinal direction extends at least partly between said cathode and said anode. The end of the cathode which is directed to the anode has a cathode tip tapering towards the anode, a part of said cathode tip extending over a partial length of a plasma chamber connected to the plasma channel. The plasma chamber has a cross-sectional surface, transversely to the longitudinal direction of the plasma channel, which exceeds the cross-sectional surface, transversely to the longitudinal direction of the plasma channel, of an opening, positioned closest to the cathode, of the plasma channel. The invention also concerns a plasma surgical device and use of such a plasma surgical device.
(FR) La présente invention concerne un dispositif générateur de plasma comprenant une anode, une cathode et un canal de plasma qui, dans sa direction longitudinale, s'étend au moins partiellement entre la cathode et l'anode. L'extrémité de la cathode qui est tournée vers l'anode comporte une pointe de cathode se rétrécissant en direction de l'anode, une partie de cette pointe de cathode s'étendant sur une longueur partielle d'une chambre de plasma reliée au canal de plasma. La chambre de plasma comporte une surface de section transversale perpendiculaire à la direction longitudinale du canal de plasma qui est supérieure à la surface de section transversale perpendiculaire à la direction longitudinale du canal de plasma d'une ouverture, la plus proche de la cathode, du canal de plasma. Cette invention concerne également un dispositif chirurgical au plasma et l'utilisation d'un tel dispositif chirurgical au plasma.
