Abstract
A surgical rasp for scraping and reshaping bones, particularly useful in cosmetic surgery, comprises a handle and a rasp surfaced insert made from a tungsten carbide attached thereto. The tooth pattern of the rasped surface is created by cutting a plurality of substantially parallel grooves into the insert and subsequently cross cutting a plurality of substantially parallel grooves thereto. Further cross-cuts can be made depending on the particular tooth pattern desired. In a preferred embodiment, the teeth so formed have a trapezoidal-shaped face and a trapezoidal-shaped back which are coextensively integral to create a cutting edge. In an alternate preferred embodiment, the teeth so formed are shaped as three-sided truncated pyramids.
