Abstract
The invention is directed to a simple attachment for a surgical bone cutt or osteotomy saw. The invention, consisting of a calibrated T-bar, saw blade holder assemblies, and cooling assemblies, permits two standard surgical saw blades to be attached in parallel to a nitrogen powered surgical reciprocating saw. Thus, a surgeon can make measured, parallel bone cuts in a single motion. The cooling assemblies, pivotally attached to the blade holder assemblies, permit water to be directed down and into the surgical site during the entire cutting operation thereby eliminating bone necrosis and reducing the risk of post-surgical bone morbidity.
