SURGICAL SAW BLADE

摘要

A surgical oscillating saw blade comprises a drive transmission proximal end, a planer midsection defining an upper and lower surface and a distal cutting edge carrying a plurality of teeth. The teeth are triangularly shaped to define a base, adjacent edges and an apex or tip. The teeth are configured by being bent inwardly or outwardly so that a minimum of tooth and blade surface is in contact with bone during a cutting procedure. The teeth are bent sufficiently to provide a kerf that is greater than the thickness of the blade.

1. A surgical saw blade for cutting bone comprising a planar body defining a drive attachment section for attachment of the blade to an oscillatory drive mechanism, a midsection and a cutting edge, said drive attachment defining the proximal end of the saw blade, said midsection extending between said drive attachment and said cutting edge, said cutting edge defining the distal end of the saw blade, said cutting edge comprising a series of aligned triangular teeth having a base, a first face, a second face and adjacent sides biased upwardly away from the base to form a tip, said inner and outer faces being on opposite sides of adjacent teeth and a portion of said first face of each tooth biased to a respective adjacent edge to define a cutting edge, each said tooth being bent so that there is minimum contact between said second face and bone during a cutting operation.
