  • Patent number: 7674267
    Abstract: An apparatus (10) for cutting bone includes a shaft member (12) having a central axis (14) and extending between a proximal end portion (16) and a distal end portion (18). The proximal end portion (16) has a first surface (32) adapted to receive repetitive impacts. The distal end portion (18) includes a cutting blade (40) extending in a first plane between a shield section (46) and a guide portion (60). The shield section (46) and the guide section (60) project axially beyond the cutting blade (40) to recess the cutting blade (40) in the distal end portion (18). The shield section (46) includes an inwardly facing shield surface (48) which extends in a second plane that is transverse to the first plane of the cutting blade (40). The apparatus (10) is a form of an osteotome that is particularly useful for certain spine-related surgical procedures.
