Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of medicine carrying plasma needle device, is used for the tooth root canal.
Background technology
Dental pulp disease and periapical disease are human commonly encountered diseases, frequently-occurring diseases, the prefered method for the treatment of these two kinds of diseases is root canal therapies, it refers to thoroughly clear up the interior inflamed human dental pulp of root pipe and downright bad material, expansion form the root pipe, and to the root pipe suitably sterilize, last close packing root pipe, infectious content prevents the generation of periapical or the healing of promotion periapical to the pessimal stimulation of periapical tissue in the root pipe to remove.Whether root canal effect and the cleaning of root pipe and root canal disinfection are improved closely related.
The existing flushing needle majority that is used for the cleaning of root pipe is the straight line hollow-core construction, and needle tip opening or sidewall opening link to each other with syringe, are used for root canal irrigation, administration and filling.This flushing needle only has single mechanical flushing action, does not have obvious bactericidal action; Syringe needle must be placed in the root pipe loosely during flushing.If flushing needle inserts root Guan Taishen, it is too tight that syringe needle can block, and easily flushing liquor and root pipe polluter extruded apical foramen of tooth; But the flushing needle position is too shallow, may cause 1/3 section flushing of tip of a root imperfection; Flushing liquor can not effectively enter narrow and small, crooked lateral branch, dentinal tubule deep, causes cleaning not thorough.Equally, aspect root canal disinfection, the medical worker adopts the drug disinfection method mostly at present.What medicinal application was maximum is the calcium hydroxide preparation, but the calcium hydroxide preparation can not effectively enter narrow and small, crooked lateral branch, dentinal tubule's deep kill bacteria; The chemical disinfection effect is arranged, but do not have root pipe cleaning effect.
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, not be subjected to after the restriction, outage of discharging gap in several milliseconds of the active particles these outstanding advantages such as the disappearance 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 201010252421.5, 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 a Simulated 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.
