Title (EN) ELECTROSURGICAL BLADE WITH A CONDUCTIVE, NON-STICK COATING
(FR) LAME ELECTROCHIRURGICALE AVEC REVETEMENT CONDUCTEUR NON ADHERANT
Abstract:
(EN) An electrosurgical blade (100) is provided having a ceramic (104) coating which is conductive, flexible and provides a surface which inhibits the build up of charred tissue. These properties enable the electrosurgical blade to deliver controlled amounts of radio-frequency energy to tissue. The manufacturing process produces a coating of titanium nitride on a stainless steel blade which is amorphous, enabling the electrosurgical blade to bend with the blade in order to perform a wide variety of surgical procedures without damaging the coating. The electrosurgical blade can therefore be used to efficiently cut, coagulate, fulgurate and desiccate tissue. While the blade is primarily used in the monopolar mode, the present invention also encompasses at least two electrosurgical electrodes having the same ceramic coating as the electrosurgical blade, and used in the bipolar mode for coagulation.
(FR) Lame (100) électrochirurgicale dotée d'un revêtement (104) céramique conducteur, flexible et offrant une surface empêchant l'accumulation de tissus calcinés. Ces propriétés permettent à la lame électrochirurgicale de délivrer des quantités mesurées d'énergie haute fréquence. Le procédé de fabrication consiste à recouvrir une lame en acier inoxydable d'une couche de nitrure de titane amorphe, permettant à la lame électrochirurgicale de fléchir et de réaliser un large éventail d'opérations chirurgicales sans endommager le revêtement. Ainsi la lame électrochirurgicale peut être utilisée pour des opérations d'incision, de coagulation, de fulguration et de dessiccation des tissus. Alors que la lame est utilisée principalement en mode monopolaire, l'invention porte également sur au moins deux électrodes électrochirurgicales présentant le même revêtement céramique que la lame électrochirugicale, et utilisées en mode bipolaire pour la coagulation.
