Abstract
The invention aims at solving the problem of changing the position of a channel along a radial direction of a handgrip in the same channel in the handgrip of an one-off dental drill cellphone, while another aim of the invention is to provide an one-off dental drill cellphone with the advantages of simple interval structure and low cost. A channel change device for the one-off dental drill cellphone is formed by one section of the handgrip and a channel arranged in the section of the handgrip. A hollow housing is arranged in the section of the handgrip. At least one channel in the section of the handgrip is communicated with one end of the hollow housing through one end of the handgrip and passes through the other end of the section of the handgrip at the other end of the hollow housing to go through out of the section of the handgrip. The one-off dental drill cellphone prepared by a channel switch device of the one-off dental drill cellphone consists of a handpiece and the handgrip. One section in the middle of the handgrip is the channel switch device of the one-off dental drill cellphone. One end of the channel switch device is connected with the tail end of the handgrip and the other end is connected with the head end of the handgrip. A certain channel in the handgrip of the invention can change the position of the channel in the handgrip through the hollow housing.
Description
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 disposable high-speed turbine tooth-drilling hand-held machine.
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 can the cross infection various diseases
And the groundwork instrument high speed handpiece that odontologist uses, every is expensive.Be exactly, 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.
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 200480006791.3 American patent of invention, discloses a kind of disposable dental instrument of compressed gas-driven type, uses when being used for that workpiece carried out dental procedure.Its handle is a blank pipe, supporter is set in the middle of in the pipe vertically, various tubules are set in the pipe, and this disposable high-speed turbine tooth-drilling hand-held machine is because handle is a blank pipe, the various tubules that are provided with in the pipe are high pressure resistant materials, to adapt to high pressure draught and current, high pressure resistant material cost height, the also corresponding complete machine cost that increased, moreover just produce vibration when high pressure draught and flow instability, cause that easily various tubules come off.
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 the O 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 the tubule of blank pipe handle and various high pressure resistant material still will be used in its front portion, still can't resolve the inherent shortcoming of blank pipe handle.
