An exceptionally durable electrical insulation coating for electro-surgical instruments is provided. The insulation coating is ceramic and exhibits excellent insulative properties in the 500 KHZ to 1 MHZ frequency range. This feature drastically reduces, if not totally eliminates, many problems of current electrical insulation materials used in electrosurgery. The insulating ceramic coating can be readily applied by plasma deposition techniques to new or existing mono/bipolar surgical instruments. The insulating ceramic coating is thermally sprayed, anisotropic, and exhibits a Young's Modulus value of no more than about 30x106 psi parallel to the coating plane. |
