I claim:
1. Completely manual rotary scalpel structure for making a surgical incision in free tissue comprising a circular scalpel blade, elongated free handle means having a longitudinal axis for holding the scalpel blade for rotation free of any other structure while moving it across an area and along a line thereon where an incision is required at a desired incision depth and means for rotating the scalpel blade only due to frictional resistance of the tissue in which an incision is being made to passage of the circular scalpel blade therethrough, which handle means is bifurcated at the end adjacent the rotary scalpel blade and the rotary scalpel blade is positioned centrally of the bifurcated end of the handle means and secured thereto for free rotation, is provided with arcuate deformation therein, the curvature of which is approximately the curvature of the end of at least one of a human finger and a human thumb, immediately adjacent the circular blade for facilitating gripping of the scalpel by a surgeon, is offset vertically at an oblique angle to the longitudinal axis thereof adjacent the circular scalpel blade at an angle of approximately 60° and is offset transversely at angle of approximately 90° to the longitudinal axis to provide a clean field of vision for a surgeon.
