Abstract
The present invention relates to a gall-resistant ribbed surgical saw blade. The blade includes longitudinal ribs extending outwardly from the opposed faces thereof which combine to define a local blade thickness greater than the width of the lateral extension of the teeth thereof. The ribs are sized and configured to slidably engage a precision slot in a guide means designed to be used to guide the blade in cutting movements. The interaction between the ribs and the slot prevents engagement of the blade teeth with the slot while reducing the surface area of engagement of the blade with the slot to reduce friction.
