The invention provides a work tip of ultrasonic subgingival scaling and a manufacturing method thereof as well as an ultrasonic subgingival scaling device. The work tip comprises a tail end connectedwith a handle, wherein a needle point is formed at the front end of the work tip; the work tip comprises a liquid infusion pipe; a liquid outlet opening is formed in a part, located on the outer surface of the work tip, of the liquid infusion pipe; the distance from the liquid outlet opening to the needle point is smaller than or equal to a pre-set distance, so that the liquid outlet opening is also located in a gap between a gingiva and a tooth root when the work tip stretches into the gap between the gingiva and the tooth root to carry out cleaning operation on a tooth root surface. By applying the technical scheme provided by the invention, the liquid outlet opening of the work tip is arranged nearby the needle point; when the work tip stretches into a periodontal pocket to clean the tooth root surface under the gingiva, the liquid outlet opening is also located in the periodontal pocket, and in the gap between the gingiva and the tooth root, so that liquid flowing out from the liquid outlet opening can be used for effectively cooling the work tip, and a medicine flowing out from the liquid outlet opening also can be in direct contact with the tooth toot surface to sufficientlyexpress a medicinal effect.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a working tip for ultrasonic subgingival scaling, a manufacturing method thereof, and an ultrasonic subgingival scaling device. Background technique [0002] Subgingival scaling refers to the operation of removing plaque and calculus on the surface of the root of the tooth with special instruments. Plaque and calculus are the main pathogenic factors of periodontal disease, so ultrasonic subgingival scaling is an important means to restore dental health. [0003] The existing subgingival scaling methods are divided into manual and ultrasonic. Among them, the manual operation takes a long time and requires high operation skills. Ultrasonic subgingival scaling uses a special ultrasonic generating device to vibrate the working tip of the subgingival scaling to remove plaque and calculus on the surface of the root through vibration. The advantages are high efficiency, time-saving and labor-sa...
