      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.

    • Claim:
      1. A curette for pituitary adenoma surgery comprising, a tubular blade portion, and a first cutting edge formed at a first end of the blade portion, and a protective shell formed at an outer periphery of the first cutting edge, a first annular ring, which is formed at a first end of the protective shell, located at the same side of the first cutting edge, and a rod portion, which is extended from a surface of the protective shell, configured to provide a handhold for a user, the first annular ring of the protective shell being able to prevent the first cutting edge of the blade portion from accidentally cutting the meninges or blood vessels during pituitary adenoma surgery, and thus the curette being able to improve the efficiency of the surgery, and being able to lower surgery time, anesthetic dosage and the risk of surgery.
    • Claim:
      2. The curette for pituitary adenoma surgery of claim 1, wherein an annular recessed portion is located between the first cutting edge and the protective shell, and a dimension of the annular recessed portion is gradually narrow from the first cutting edge to the protective shell to form into a tapered shape, leading to increasing the sharpness of the first cutting edge.
    • Claim:
      3. The curette for pituitary adenoma surgery of claim 1, wherein a surface of the first cutting edge shrinks into a surface formed by the first annular ring.
    • Claim:
      4. The curette for pituitary adenoma surgery of claim 1, wherein a second cutting edge is formed at a second end of the blade portion, and a second annular ring formed at a second end of the protective shell is located at the same side of the second cutting edge, leading to enhancing the efficiency of surgery.
    • Claim:
