Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an optical fiber microwave plasma dental root canal sterilizing device.
Background
The oral cavity is an organ with high morbidity of human bodies, diseases in the oral cavity are more prominent in the problems of dental pulp diseases and apical inflammation, and the pathogenic factor is mainly microbial infection. Bacteria enter the pulp through the dentinal tubules, pulp exposure, periodontal, etc., producing endotoxins, destructive enzymes, and metabolites. Finally, bacteria are attached and propagated on dental pulp and tooth root apex to form inflammation, and a biological film is also formed seriously, so that pathogenic bacteria cannot be thoroughly eliminated by common medical means, and the disease is repeated. The most effective treatment method in the prior art is root canal therapy, wherein the root canal therapy process is to cut decayed dentin after local anesthesia, open the pulp chamber and take out infected pulp, enlarge the root canal, wash the inside of the root canal with disinfectant, and finally fill the drilled hole. The most critical link is disinfection, which may cause re-infection of pulp cavity once the disinfection is not complete, resulting in recurrence of the patient and severe need of tooth extraction.
Based on the defects of traditional disinfection technologies such as drug disinfection, laser disinfection and ultrasonic disinfection, the plasma disinfection technology is developed and applied. The plasma disinfection is that working gas is ionized by an electric field generated by a high-voltage high-frequency power supply, so that high-density high-energy electrons, free radicals, charged particle groups and other substances are generated, and the aim of sterilization and disinfection is achieved under the action of the particles. The concrete functions are as follows: (1) the high-energy electrons influence the charge balance of the bacterial cell membrane to achieve the effect of destroying the cell membrane and killing bacteria; (2) free radicals such as NO and OH have strong oxidizing property and can directly kill bacteria; (3) the plasma can also generate a trace amount of ultraviolet radiation to directly destroy the DNA of bacteria, and has a strong killing effect on the bacteria.
In general, the plasma root canal sterilization equipment adopts a dielectric barrier structure to discharge micro-arc, the air outlet is 2-3 mm and penetrates into an affected part to generate plasma, but the discharge mode can generate the micro-arc while generating the plasma, so that the plasma has strong stimulation effect on sensitive dental pulp and tooth root, and a human body can generate strong pain. The general gas outlet is made of glass capillary, so that the hardness is high, the operation requirement is difficult to achieve in the oral cavity, and more importantly, the size is large, and the root of dental pulp is difficult to achieve complete disinfection.
