Surgical reciprocating blade assembly including a static guide bar, teeth that project from a side of the guide bar and a drive rod that reciprocates the teeth

Abstract

A reciprocating blade assembly for use with a surgical saw comprises a reciprocating member, the reciprocating member including a proximal end feature for engaging a drive member of the of the saw that, when actuated, reciprocates the reciprocating member. The reciprocating blade assembly further comprises teeth that extend outwardly from a side of the reciprocating member, the teeth adapted to form a kerf in tissue against which the teeth are pressed. The reciprocating member is contained in a guide bar assembly that includes features for engaging with a complementary fastening assembly that holds the guide bar assembly static to the saw and an opening located in a side of the guide bar assembly wherein the reciprocating member is mounted in the guide bar assembly so the teeth extend out of the side opening, wherein said guide bar assembly is dimensioned to fit into the kerf formed in the tissue cut by the teeth.
