Abstract: A surgical rongeur device has an interchangeable, locking tip at a cutting end for engageable replacement with a variety of cutting tips for facilitating sterilization and blade changes. A detachable linkage between a handle portion and an interchangeable cutting tip (tip) provides a strong connection for actuation by the handle end but allowing for tip replacement via slidable, lateral displacement of the tip. The tip includes a blade and footplate formed from an amorphous metal for longevity and strength advantages. A handle provides a lever to actuate the tip from slidable communication via the detachable linkage. An interlocking member extends longitudinally from the handle into an internal slot on the tip for locking the tip by preventing lateral movement out of alignment with the handle. The aligned tip is responsive to actuation from the handle via a rail for disposing the blade longitudinally against the footplate.
