Description

A kind of plastic handle disposable high-speed dental turbine unit

Technology neck city:

This product belongs to medical treatment and goes up the hand tool that bores the tooth of grinding one's teeth in sleep, specifically a kind of entity handle disposable high-speed dental turbine unit.

Background technology:

The dental unit that odontologist uses is made up of parts such as air compressor, air supply system, water system, high speed turbine mobile phones, and high speed turbine mobile phone is mainly reached in machine joint etc. by head, handle and constitutes.Rotor is the core of head, is combined by bearing, wind wheel and mandrel, and the rotary principle of mobile phone is to utilize mobile compressed air that wind wheel blade is exerted pressure, and promotes blade, makes the wind wheel high speed rotating.Its revolution height and balance, cutting drilling power are strong, can alleviate the labor intensity of patient's misery and odontologist, increase work efficiency, so replaced electromotive dental drill once coming out, also the appearance of high speed turbine dental drill machine being called the revolution second time of dentistry dental drill thus, also is the indispensable ideal dental equipment that the Zhi Ya of odontologist, edge are joined various artificial tooths.

Yet after odontologist used end of operation, the electromagnetic valve in the multipurpose therapy unit quit work, and electromagnetic valve upper end Exhaust Open is got rid of residual air.And the residual air after the high speed handpiece acting is also outside the mobile phone exhaustor is discharged mobile phone, high speed handpiece can quit work, and the high speed handpiece exhaustor is when discharging in the mobile phone residual air, can form generation " resorption power ", blood in the disease population, saliva and various bacterial virus partly can be drawn back in the lacuna of mobile phone, use for second patient as not strict thorough disinfection, just blood that can last patient is remaining, saliva and various bacterial virus are injected in another disease population, the cross infection various diseases is as acquired immune deficiency syndrome (AIDS), hepatitis B etc.According to World Health Organization (WHO),, still have every year people more than ten to become patients infected hiv because of seeing tooth in dental clinic and the very strict American-European countries of hospital disinfection measure.So, toothwash, control tooth, in the oral disease therapeutic such as have a denture made,, just might infect diseases such as acquired immune deficiency syndrome (AIDS) and hepatitis B if not strict as apparatus sterilizations such as the dental drill that uses, high speed handpiece, cutter heads.

And the groundwork instrument high speed handpiece that odontologist uses, every is expensive.Home-made about thousand yuan every, the need 2,3 of import are done one in unit.Accomplish the sterilization of " people one machine " strict sterilization, the high speed handpiece that each dental clinic must be bought average day outpatient service amount number equal number could have enough to meet the need sterilization, this is a no small investment number, at a high speed in machine again very " enervated ", maintain the oil dripping deficiency at ordinary times, bearing will damage, and one repair must tens up to a hundred yuan, and high temperature sterilize also reduces the service life of high speed handpiece.The disinfection cost of leader's machine is 2 yuan, and the special-purpose sterilizing equipment decontaminating apparatus of mobile phone is homemade at 30,000 yuan of one cover, and import is at 4～50,000 yuan of one cover.Have 1000 high speed handpieces to calculate by a tame large-scale specialized department for stomatology hospital, need pay 2000 yuan disinfection cost every day.One month is exactly 60,000,1 year 720000 yuan, general small-scale dental clinic also needs several ten thousand yuan every year.

In brief, common used dental drill is made by high-grade metal is accurate, cost an arm and a leg, dental drill frequency of utilization in the odontopathy diagnosis and treatment is high especially again, so can not accomplish that one suffers from machine use by standby too many dental drill, cause knowing perfectly well that dental drill has higher cross infection probability, still the situation that will generally use makes it to become the important channel that present infectious disease is propagated.This just needs disposable high speed turbine dental drill hand piece, if will reach disposable purpose, then must satisfy under the strong prerequisite of dental drill high speed rotating and balance, cutting drilling power, reduce the production cost of dental drill as much as possible, promptly abandon the financial burden that is brought after making general patient can accept to use.Causing the present too high principal element of dental drill cost of using is high-grade metal material, high pressure resistant pipeline and complicated internal structure.

Based on above-mentioned consideration, the patent No. is 01274713.0 utility model patent, a kind of disposable high-speed turbine tooth-drilling hand-held machine is disclosed, it is the handpiece body that is connected with the dress drill point at the head of machine handle, the afterbody of machine handle connects water, gas quick connector, turbine drives turbine wheel shaft and makes the drill point rotation in its handpiece body, drill point one end is held mechanisms grip, high pressure air flue, water channel and return-air road from water, gas quick connector one through to handpiece body, the rotation of driving turbine, the high pressure water channel leads to handpiece body from water, gas quick connector, and dental drill places and meets in the packing of requiring of sterilizing; Handpiece body made from easy processing metal and inner turbine mechanism thereof be connected and fixed with engineering plastics, the nonmetal machine handle of making of rubber, the turbine wheel shaft end that drill point one side is installed in handpiece body is covered with gas-tight resorption glue cover, is connected with anti-resorption check valve in the middle of being positioned at the high pressure water channel at machine handle place.This disposable high-speed turbine tooth-drilling hand-held machine is though make handpiece body complex structure, manufacturing cost height with easy processing metal.

The patent No. is 200610200742 utility model patent, a kind of disposable use high speed turbine dental drill hand piece is disclosed, the employing engineering plastics are once molding formed, the rear operating handle structure of a plurality of parts has been become a part, this machine handle one end links to each other with machine handle before the mobile phone, the other end is made and is adapted to the various fast tail structures of inserting the air water joints, it is characterized in that: link to each other with machine handle before the mobile phone and partly adopt connected structure, and seal trachea and water pipe from handpiece body with 0 RunddichtringO.Machine handle rear portion can be designed to the various structures of different size, can patch the various fast air water joint of inserting from dental unit.This invention to the contribution of prior art is, the part hand grip control is made the entity handle, various passages are set in the handle, but its cervical region is the tubule of the built-in various high pressure resistant material of hollow pipe, because cervical region is thinner, the tubule inconvenience of various high pressure resistant material is installed, moreover for disposable use high speed turbine dental drill hand piece, there is no need to be provided with so much part.
