Abstract
An osteotomy blade saw is provided in left-offset and right-offset embodiments for performing sagittal ramus osteotomies. The blade saw has first and second straight arm portions forming an obtuse angle between them, the end of the second arm terminating in a neck portion which angles acutely away from the plane containing the arms and terminates in an end portion on which a cutting blade is mounted. The blade lies in a plane parallel to the plane containing the arms and is offset to the right and left depending on the embodiment. Supplying reciprocating linear motion to the first arm allows the saw to be used in cutting bone. The blade saw in its two preferred embodiments can be used to score and cut the underside of the right and left inferior borders of the mandible, respectively, through incisions inside the mouth.
