Abstract
A method of making a surgical incision comprising power driving a rotating scalpel blade and drawing the blade across an area and along a line where an incision is required. When the blade is circular, the circumferential speed of the blade relative to the tissue at the incision is maintained above 4 centimeters per second and is preferably between 10 and 25 centimeters per second, i.e. approximately 18 centimeters per second, for example. Further in accordance with the invention, the scalpel blade may be pushed or pulled across the area in which an incision is required. Also, the circular scalpel blade may be driven in a direction such that the periphery thereof at the incision travels in either a direction opposite to or the same as the direction of movement of the blade drawn along the line where the incision is required. Also, in accordance with the invention, the blade is illuminated any time power is applied to the scalpel, and the depth of cut may be physically limited by structure specifically designed and provided for such depth limiting.
