Abstract
A surgical cutting blade for use in an electrosurgical scalpel includes a thin flat ceramic substrate having a rounded tip where the edge portion of the substrate on the opposed major surfaces thereof are beveled. A pattern of metallization is provided on the opposed major surfaces of the blade substrate with the metallization extending over the tapered portions. The substrate is then back-ground to form a blunt edge extending between the tapered surfaces at the edge of the substrate. The metallization pattern further includes traces extending from the conductors along the blunt working edge of the blade to the handle receiving portion thereof and provide a means whereby RF energy may be conducted to the metallized working edge of the blade.
