Description

Can prevent inspiratory dual-purpose saliva aspirator of bone meal

Technical Field

The invention belongs to the technical field of oral medical auxiliary instruments, and particularly relates to a dual-purpose saliva aspirator capable of preventing bone meal from being inhaled.

Background

Periodontal disease is a chronic infectious disease that occurs in the supporting tissues of the teeth. The periodontal disease rate in China reaches more than 90 percent, and periodontal disease is the main reason of adult tooth loss and seriously affects the life quality of patients. The regeneration capability of the alveolar bone is strong, and the regeneration of the alveolar bone can be realized through periodontal bone grafting under the conditions of infection control and good space maintenance for patients with periodontitis with three-wall bone defect lower pockets or II-degree root bifurcation lesions and with a root bifurcation area covered by gingiva. Furthermore, when a partial missing tooth is implanted into a tooth, it is necessary to increase the bone mass of the alveolar bone in the vertical or horizontal direction, and in this case, an implant is also necessary.

The saliva aspirator is the indispensable utensil in the oral cavity diagnosis and treatment process. Saliva secreted by the oral cavity, cooling water brought by instruments in treatment and blood of patients cause wet interference and pollution to the oral treatment area to different degrees. In operation, saliva, cooling water and blood of a patient are timely discharged through a saliva suction device, and it is necessary to keep the operation field clear and relatively non-wet.

In the bone grafting, the operator sends bone powder into alveolar bone defect district to promote new bone to produce, in order to keep the visual field clear in art district, need to inhale art district blood, saliva away with saliva aspirator, but the saliva suction head hole of current saliva aspirator is great, and the bone powder of implanting during the saliva aspiration easily gets into the saliva aspirator along with saliva, blood etc. influences the treatment of bone regeneration.
