[0002] A dental curette is a commonly used dental medical device used to remove tooth fragments and debris, as well as scrape granulomas, cysts, alveolar diseased tissue, and bone decay during oral surgery. It typically consists of a rod with scraping blades at either end, with one blade being flat and the other pointed.

[0003] Because the rod of the dental curette is thin and its outer surface is smooth and straight, medical staff need to hold it tightly with their index finger and thumb, and use the knuckle of their middle finger to lift the dental curette. When scraping with force, the dental curette is likely to slip out of the hand or slip. Moreover, because the scraping blades at both ends of the dental curette have different functions, medical staff need to skillfully rotate the curette in their hands when switching, or put the curette down and pick it up again to switch, resulting in a delay in the operation of switching the scraping blades and insufficient convenience. In view of the above problems, those skilled in the art have proposed a dental curette solution that can solve the above problems. Utility Model Content
