Abstract
A vitreous enamel coating for an electrosurgical metal cutting blade, the coating having a coefficient of thermal expansion substantially near the coefficient of thermal expansion of the metal cutting blade. Selection of materials having similar coefficients of thermal expansion results in an electrosurgical cutting blade with an improved insulating layer, substantially improved durability, or both.
Claims20
An electrosurgical cutting blade comprising:
- (a) a metal electrode having a coefficient of thermal expansion and an exposed edge, and
- (b) a solidified vitreous enamel coating on at least a portion of the metal electrode but not on the exposed edge, the vitreous enamel coating having a coefficient of thermal expansion within less than ±30% of the metal electrode coefficient of thermal expansion.
