This instrument is used to carefully smooth bone. With a small spoon on the end of the tool similar to that of an ice-cream scoop, a curette allows the surgeon to scrape away bone. The spoon of the bone curette has durable, sharp edges.

When combined with dilatation, both evacuation and curettage can be used up to about the 16th week of pregnancy.
