Abstract (en)
[origin: WO9701305A1] A bipolar endoscopic scissors (10) is provided with scissor blades (26, 128) where at least one scissor blade is coated with an electrically nonconductive ceramic from its cutting edge along at least a contiguous portion of its shearing surface. The coated blade is provided with a cutting edge having an obtuse included angle which is preferably between approximately 95 degrees to 140 degrees, and more preferably between 110 degrees and 120 degrees. The blades according to the invention may be configured in several different ways with regard to the number of layers and types of material used, the extent of the ceramic coating, and whether one or both blades are configured in an identical manner. The blades, according to the invention having cutting edges defined by obtuse angles, cut well and provide a good cutting feel to the practitioner, while preventing the ceramic coating from chipping at the cutting edge.
