About the Cone Ring Curette
The Cone ring curette is a bone curette whose working end is an open ring rather than a cup. The ring's edge shaves soft tissue and thin layers of bone as it is drawn across a surface, and loosened material passes through the opening.
It is listed by spine instrument makers in straight, angled and laterally angled forms, often with numbered sizes and phenolic or other handles. One spinal implant company also includes a Cone ring curette among its instruments.
Ring size, angle and handle style differ by manufacturer, and some ranges offer delicate versions.
