[0002] Oral hook needles are widely used in dentistry, mainly for repairing defects or damages of oral tissues such as teeth and gums, and for cleaning foreign objects such as dental plaque and tartar around the gums. After searching, the Chinese patent publication number is CN220158412U, which discloses an oral hook needle for dentistry, including a connecting groove rod and a connecting rod, a threaded rod is fixedly arranged on the connecting groove rod, and the connecting rod is hollow inside. When the utility model is in use, it is convenient to clean the patient's oral cavity by arranging the telescopic tube and the nozzle outside the rod body. However, since the structure is located outside the rod body, it is cumbersome for medical staff to operate, which affects the use effect. At the same time, the tip of the hook needle of the structure is connected by a spring and a pull rope. etc. so that it can be adjusted, but the singleness of the spring support can easily lead to insufficient tip stability when cleaning hard objects (such as dental calculus), increasing operational risks. At the same time, the moist environment in the oral cavity can easily cause liquid to penetrate into the hook, causing inconvenience for subsequent disinfection and cleaning work, reducing the sanitary safety standards and reuse rate of the tool, and having poor practicality. The oral hook is adjusted in length through a threaded connection, but the importance of the snap-fit ​​structure is ignored, and there is a lack of an effective locking mechanism, which may cause loosening due to external force during use, which not only affects the operational stability, but may also cause unnecessary harm to the patient and cannot meet the use requirements. Therefore, an oral hook for stomatology is proposed to solve the above-mentioned problems. Utility Model Content
