Abstract

A surgical handpiece adapter for converting rotary motion of a powered surgical handpiece into reciprocating motion to drive a cutting member includes a rear drive shaft for being removably coupled to a rotatable drive shaft of the handpiece, a front drive shaft for being removably coupled to the cutting member and a motion converting mechanism causing reciprocation of the front drive shaft and, therefore, the cutting member coupled thereto, in response to rotation of the rear drive shaft by the drive shaft of the handpiece. A handpiece adapter assembly is formed by an adapter and a cutting member coupled thereto, and a powered surgical handpiece assembly is formed by an adapter, a cutting member coupled to the adapter and a powered surgical handpiece coupled to the adapter. A cutting member includes a surgical suction rasp for being reciprocatively driven to cut anatomical tissue and having a tissue cutting surface and a suction passage with an inlet opening along the tissue cutting surface for removing anatomical debris from an operative site at which the rasp is used. A cutting member includes an osteotome for being reciprocatively power driven to cut anatomical tissue and having a cutting edge and a blunt tip extending distally of the cutting edge. A method of facial surgery includes the steps of reciprocating a distal end of a rasp to reshape the nasal bone of a patient and removing anatomical debris through a suction passage of the rasp while the nasal bone is being reshaped. Another method of facial surgery includes the steps of reciprocating a distal end of an osteotome via a powered surgical handpiece and moving the distal end of the osteotome, while it is being reciprocated, forwardly along the nasal bone of a patient in a predetermined path with a cutting edge of the osteotome in contact with the nasal bone to make a cut of desired length in the nasal bone along the predetermined path.
