A curette such as the Ray Pituilary curette is an instrument used by neurosurgeons. It is a tool which is used to scrape the surface like tissue or the muscle/tissue inside the opening of a body. There are many sizes available of curettes and these can easily be bought from a medical supplier. Disposable as well re-usable curettes can be found. The tip of the curette has a very sharp blade and is generally at an angle. Versions of this instrument include wire loops which help in the tool being gentler while being used.
