Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, and particularly relates to a rubber dam face bow. BACKGROUND

[0002] The rubber dam is a soft rubber sheet used to isolate the teeth needing treatment in the treatment process to prevent the treatment area from being contaminated by saliva, blood and other liquids in the oral cavity, and can also protect the soft tissues in the oral cavity to avoid accidents such as accidental swallowing and accidental pharyngeal aspiration during the treatment process.

[0003] The rubber dam face bow is an auxiliary tool used in dental treatment. The face bow is usually made of metal and is mainly used to support and fix the rubber dam. The middle region of the rubber dam is punched and then passes through the diseased teeth. The rubber dam face bow supports the edge of the rubber dam, so that the whole rubber dam is taut, and the correct position and stability of the rubber dam in the oral cavity are ensured. The use of the face bow can improve the clarity of the doctor's view.

[0004] Since children are at different ages, their face shapes differ greatly, and the face shapes of some adults differ greatly from those of others. However, most rubber dam face bows are standard products and cannot be adjusted according to the face shapes of patients. They cannot flexibly adapt to different face shapes and sizes of oral cavities, and cannot meet the oral cavity structures and treatment needs of different patients. The oral rubber dam frame does not have a fine adaptive adjustment mechanism, which can easily affect the doctor's observation of the internal situation of the oral cavity and the doctor's operation.
