[A new cartilage crushing instrument for rhinoseptoplasty]

The method of so called "Cartilage Crushing" is used for bone or cartilage which is temporarily removed from the nasal septum during surgery in order to straighten it, remove tension and then to replant it. Basically the pieces to be treated are placed between two metal blocks which are pressed together on impact by a hammer. The newly developed instrument presented here is not joined together in the form of an axle. The new instrument has a larger circular formed area with a diameter of 4 cm. The anvil has a rounded surface enclosed by cylindrical walls, while the pressure pestle functions as a piston within the cylindrical walls. This system allows the bone cartilage on the surface to receive an even impact on the whole section through the piston-like action of the pressure pestle, thus making it possible for the crushed cartilage to be evenly extended in all directions.
