  • Patent number: 10080580
    Abstract: A curette for pituitary adenoma surgery may include a curette having a tubular blade portion. A first cutting edge is formed at a first end of the blade portion, and a protective shell is formed at an outer periphery of the first cutting edge. A first annular ring formed at a first end of the protective shell is located at the same side of the first cutting edge, and a rod portion extended from a surface of the protective shell is configured to provide a handhold for a user. The first annular ring of the protective shell can prevent the first cutting edge of the blade portion from accidentally cutting the meninges or blood vessels during pituitary adenoma surgery. Thus, the curette can improve the efficiency of the surgery and lower surgery time, anesthetic dosage and risk of the surgery.
