Ballenger swivel knife, which is a uniquely designed knife that consists of a flat handle, a shaft and two prongs which harbor a rotating blade.
The blade can rotate 360 degrees in its axis and swivel at the tip. Therefore, it can cut the tissues based on the direction of the operators hands.
This is useful in submucous resections of the septum and in rhinoplasty and tympanoplasty procedures, where more cartilage can be easily removed at once without the operator needing to reposition the handle in every manipulation.
The Length is 20cm with multiple choice of blade tip size.
