ABSTRACT:
The rasp-like reaming instrument is constructed as a hollow body with exterior teeth and openings adjacent the teeth. During use, bone material which is peeled off by the teeth is directed through the openings into the interior of the body to avoid accumulation of the material under the teeth. The cutting edges of the teeth remain unencumbered during a reaming operation.
