ABSTRACT:
A surgical cutter for preparing recipient sites for square scalp plugs in hair transplanting has four disposable blades removably attached to the four longitudinal sides of a core having a square cross-section of predetermined dimensions corresponding to the width of each blade and to the area at the surface of the hole to be excised. Each blade projects a predetermined distance beyond the end of the core equivalent to the required depth of cut and has a sharpened inclined cutting end edge extending from a point located at one side edge inwardly to the opposite side edge in guillotine fashion. The side of the blade adjacent the point is also a sharpened cutting edge extending inwardly therefrom. One blade point is located in each corner of the square projecting from the recessed side of the adjacent blade whereby the side cutting edges are operatively exposed for cutting a subdermal portion of the scalp on rotation of the core approximately 3/4 turn after the square has been cut by the inclined end cutting edges of the blades. A handle removably accommodates the cutter in operative position and in a reverse blade protective position for handling during sterilization.
