Description

A kind of medicine carrying plasma pneumatic sand blasting rifle

Technical field

This utility model belongs to medical apparatus and instruments, is specifically related to a kind of medicine carrying plasma pneumatic sand blasting rifle, is used for the associated treatment of tooth body dental pulp disease and periodontal disease.

Background technology

China's tooth body dental pulp disease and periodontal disease (comprising peri-implantitis) sickness rate are very high, and the bacterial plaque of dental surface or implant surface, tartar are to cause the pathogenetic major reason of these diseases, and the dentistry sand-blasting gun then is a kind of therapeutic device of removing these causes of disease.Existing dentistry sand-blasting gun mostly is the pneumatic sand blasting rifle, comprise fuselage, nozzle, handle and interface, sand-spraying pot and interface are housed on the fuselage, nozzle is connected on the handle, handle is connected with fuselage, interface is used for connecting water, gas circuit, during use interface is connected with Pneumatic dental therapeutic equipment corresponding interface, rely on Compressed Gas and the high-pressure hydraulic pump of Pneumatic dental therapeutic equipment to penetrate the high-speed jet that contains air, sand and aqueous mixtures from nozzle, again nozzle alignment is suffered from tooth and carry out the treatments such as scaling, polishing.But existing sand-blasting gun sandblast treatment only has the mechanical removal effect, and sterilization effect is not good enough; Only have and sand blasting is mapped to lesion region just can reaches therapeutic efficiency.But anatomic form, the pathological changes type of much suffering from tooth are complicated, and particularly the periodontal pocket of narrow and small, crooked lesion region such as complexity bottom, dentinal tubule deep and implantation body deep are surperficial, and sandblast is difficult to arrive; If with method use in conjunction such as sandblast treatment and ultrasonic scaling, hand scaling art, Drug therapys, can improve curative effect, but operation is more loaded down with trivial details, the course for the treatment of is longer; Therefore, existing sand-blasting gun can not effectively be controlled and thoroughly eliminate the oral cavity paathogenic factors such as bacterial plaque, tartar, is difficult to reach the target of keeping oral health, prevent disease generation or recurrence.

And in recent years, it is found that low temperature plasma can sterilization, and kill cancerous cell, promote blood clotting, thereby be subject to people at medical domain and greatly pay close attention to.Plasma is material the 4th attitude after solid-state, liquid, gaseous state.When applied voltage reaches the breakdown voltage of gas, gas molecule is breakdown, generation is rich in the atom of a large amount of active particles such as ion, electronics, excited state and molecule and free radical etc. at interior mixture, these active particles can be efficiently and microbial interaction, the purpose that just can reach inactivating pathogens and remove pollutant at short notice.To have a sterilization safety quick and for gas form can enter the gap of narrow and small bending, these outstanding advantages such as be not subjected to disappear in several milliseconds of the active particles after the restriction, outage of discharging gap, unharmful substance is residual because of low temperature plasma, and lower temperature plasma technology has demonstrated good effect in the research of the aspects such as the cleaning of stomatology field such as dental instruments and sterilization, dental caries therapeutic, tooth root canal, application.Be called " production method of the low temperature plasma that a kind of human body can directly touch " patent of invention numbers 201010252320.5, utility model patent numbers 200920268597.2 is called " plasma needle device " and document Xinpei Lu, et al. " A single electrode room-temperature plasma jet device for biomedical applications " (" the single electrode room-temperature plasma mjector that is used for biologic medical ") APPL.Phys.Lett.92,081502,2008 grade has the content report of introducing low temperature plasma generator and treatment oral disease.Recently, come the relevant report of dental treatments root pipe to deliver relevant for utilizing low temperature plasma to load medicine again, such as document Xincai Zhou, etal. " The Antimicrobial Activity of an Atmospheric-Pressure Room-Temperature Plasma in aSimulated Root-Canal Model Infected With Enterococcus Faecalis " (" the room temperature atmospheric plasma is to the antibacterial activity of enterococcus faecalis infectious root canal model "), Plasma Science, IEEE Transactions on, 2010,12 (38): these researchs of 3370-3374. are found, when low temperature plasma loaded upper medicine, the two-way interaction can produce good collaborative sterilization efficacy.
