Abstract
An over the wire scalpel for performing a dermatotomy that produces a skin nick features a triangular shaped blade with a pair of cutting edges that meet to define a tip. The blade is connected to a handle and a central lumen passes through both. The leading opening of the lumen is positioned at the blade tip so that it is symmetrically abutted by the cutting edges. A blocker that limits the depth of blade travel is positioned upon the handle adjacent to the blade. A stylus may be placed within the central lumen so that the scalpel may be used without a guidewire or with a guidewire that has a diameter significantly smaller than that of the central lumen.
