Rotary scalpel structure and method which rotary scalpel may be either manual or automatic. The manual rotary scalpel structure includes an handle having a bifurcated end between the ends of which a circular scalpel blade is mounted for rotation. The automatic rotary scalpel includes a circular scalpel blade secured at one end of a blade support arm connected to a handle having a drive motor secured to the other end thereof and means extending through the handle and the blade support arm for rotating the circular scalpel blade on energization of the motor. The automatic rotary scalpel includes structure for releasably securing the blade support arm to the handle. A circular scalpel blade is also provided which has concave surfaces to reduce blade friction along with a blade container for transporting and storing circular scalpel blades.
The method includes manually or automatically rotating a circular scalpel blade and drawing it across an area in which an incision is required. With the automatic rotary scalpel structure, the blade is rotated prior to the incision being made. In either case, it is desirable to rotate the rotary scalpel blade circumference at between 4 and 7 centimeters per second.
