Suction tip and saliva ejector for periodontal cleaning of oral cavity

Abstract

The present invention relates to the technical field of medical equipment, and in particular to a suction tip and a saliva ejector for periodontal cleaning of oral cavity, including a cap with one end opening in a hollow structure. First notches connecting inner and outer sides of the cap are opened at an edge of an outer end face of a closed end of the cap, and the first notches extend toward a side wall of the cap; the closed end of the cap is arranged with a rotating sleeve with one end opening in a hollow structure, the closed end of the cap is inserted into an open end of the rotating sleeve and is coaxially rotated and matched; and second notches connecting inner and outer sides of the rotating sleeve are opened at an edge of an outer end face of a closed end of the rotating sleeve, and the second notches extend toward a side wall of the rotating sleeve; and the first notches are located on a rotation trajectory of the second notches. In the present invention, the problem in the related art that a size of a suction channel of a suction tip in a saliva ejector is fixed, making it difficult to adjust according to actual conditions of different patients or different stages of the same treatment process and thus having certain limitations is solved.
