Abstract:
Provided is a lingual bracket, which comprises a bracket base (1), a bracket wing (2), and a spring (3). One end of the upper surface of the bracket base (1) is provided with fixed wings (11), the other end of the upper surface of the bracket base (1) is provided with an auxiliary pipe (12), and the bottom surface of the bracket base (1) is provided with an anti-skid bonding surface (13). The bracket wing (2) is provided with a pin (21) and a wing part (22), and can be positioned on the fixed wings (11) by means of the spring (3) arranged on the pin (21) in a sleeving mode. A longitudinal channel (111) is formed on the central axis of the fixed wings (11) of the bracket base (1), and a transverse channel (112) is formed on the rear end faces of the fixed wings (11). The width of the pin of the bracket wing (2) is equivalent to that of the longitudinal channel (111), and the pin can be placed in the longitudinal channel (111). A wide extension part (23) is provided at a joint of the pin (21) and the wing part (22). When the pin (21) is placed in the longitudinal channel (111) and the spring (3) is pushed forward, the wide extension portion (23) can be inserted into the transverse channel (112) to form a positioning structure. By utilizing the two criss-cross channels on the bracket base (1), the constraint on the bracket wing (2) is formed, and the bracket has the characteristics of ingenious design, simple structure, easiness in processing, and convenience in clinical operation.
