Abstract:
1. A surgical saw blade comprising: a planar blade body, said blade body shaped to have opposed proximal and distal ends and a longitudinal axis that extends between the ends; geometric features integral with the proximal end of said blade body to couple said blade body to a drive head so that said drive head can oscillate the blade body so that the distal end pivots relative to the proximal end; and a plurality of teeth that extend forward from the distal end of the blade body, wherein said blade body is further formed to define two spaced apart tines that extend proximally from the blade body distal end, said tines spaced symmetrically from the blade body longitudinal axis, said tines having distal ends that collectively form the distal end of said blade body wherein at least two said teeth extend forward from each said tine, said tines being collectively shaped to define an opening located between the distal ends of said tines that has a width perpendicular to the blade body longitudinal axis and a void space that is proximal to the opening between the distal ends of said tines and proximal to where said teeth extend forward from said tines, the void space extending through said blade body and being contiguous with the opening between the distal ends of said tines and having a width perpendicular to the blade body longitudinal axis that is greater than the width of the opening between the distal ends of said tines.
