The Rasp Downstroke X-Fine Teeth GG is a specialized surgical instrument designed for bone shaping and smoothing during orthopedic and maxillofacial surgeries. The x-fine teeth are ideal for delicate bone contouring, providing a more refined finish compared to coarser rasps. The downstroke design allows for controlled bone removal with minimal trauma to surrounding tissues. The GG likely refers to a particular style or manufacturer designation.
