  • Device for plasma-arc cutting of biological tissues
    Patent number: 4855563
    Abstract: The device includes a cathode assembly (1) having a housing (3) and an electrode (6) with a tapering portion (19), and an anode assembly (2) having a housing (20) and a nozzle (12) receiving the tapering portion (19) of the electrode (6), the nozzle (12) successively defining a cylindrical chamber (11), a tapering chamber (21), an arcing chamber (7) and a plasma jet forming chamber (23).
