Description
Technical field
The present invention relates to medical apparatus, specially a kind of dentistry sandblasting handle.
Background technology
Currently, applied to the clinical mode to clean one's teeth mainly have hand device scrape control, ultrasonic scaling and sandblasting clean one's teeth, mainly remove tooth
Dental calculus, plaque, tea stain, the crock etc. of tooth surface attachment.
Hand device, which is scraped, to be controlled when clearing up dental surface, can only be contacted with facing point, line, less efficient, and repeatedly to facing into
Row, which is scraped, to be controlled, and dynamics is unable to control, and dental surface can be made to form recess and punching；The operation tip that ultrasonic scaling passes through high-frequency vibration
Scaling is carried out to tooth, scaling efficiency can be effectively improved, but the impact of operation tip high frequency can still cause compared with macrolesion tooth, and
And facing is coarse or has cut, it is easier to bacterial plaque be made to adhere to again；In addition, adjacent surface between tooth, hand device scrape control it is clean with ultrasound
The operation tip of tooth cannot touch, and dental calculus, bacterial plaque etc. are not easy to remove, this is also easy induction dental calculus and generates again.
Sandblasting clean one's teeth its principle be using swiftly flowing gas drive sodium bicarbonate crystal formed particle flux, by tiny
Nozzle act in dental surface, remove the dental calculus and bacterial plaque on facing using the kinetic energy of particle flux.
Main two kinds of sandblasting handles in the market, the first sandblasting handle arrangement are that middle handle is equipped with silo, and handle is straight
It connects and is connected with air source, the opening and closing of sandblasting valve button control front end nozzle, in venting process, the forward and backward generation pressure of sandblasting valve door
Force difference makes to generate negative pressure inside silo, and external pressure enters from the venthole in silo in tank, and sand grains is under the action of negative pressure
It is sprayed from nozzle；Second of sandblasting middle handle has a spherical cavity, and in venting process, air-flow, which blows afloat emery dust by spherical cavity, to be brought into
Blast nozzle simultaneously sprays, and reaches sandblasting effect.
The shortcoming of both sandblasting handles has：
1, complicated, processing cost is higher.
2, poor reliability is used for a long time, it is not easy to replace nozzle or handle.
3, handle is larger and heavier, it has not been convenient to which doctor operates.
Invention content
In view of the deficiencies of the prior art, a kind of simple in structure, stable the technical problem to be solved by the present invention is to propose
Good, the easy to operation dentistry sandblasting handle of property.
The dentistry sandblasting handle that can be solved the above problems, before technical solution includes hand-held shank and is set to hand-held shank
The abrator head at end, except that：
1, the hand-held shank includes coaxial front housing, connector I and tail-hood, and rear end and the tail-hood of the connector I pass through spiral shell
Line structure connects, and the front end of connector I connects front housing rear end by clamping structure, and sand-feeding tube is coaxially arranged in connector I, described into sand
The connector I of pipe side is internally provided with into water sebific duct, and the sebific duct connector in tail-hood is stretched out in the rear end connection of the water inlet sebific duct.
2, be coaxially provided with plug in the front housing, be coaxially provided with out sandpipe in the plug, it is described go out sandpipe rear end connect
The front end of logical sand-feeding tube goes out sandpipe front end connection abrator head.
3, the abrator head includes connector II, blast tube, sparge pipe and spray lid, before the connector II is coaxially built in plug
End, II rear end of connector are embedded in sandpipe front end by helicitic texture is connect is gone out in spray lid, and the spray lid passes through screw thread with front housing
Structure connects, and sparge pipe and the blast tube of coaxial package are placed in connector II, and the blast tube is connected to out sandpipe, the spray backward
Water pipe with blast tube cover and become nozzle forward by pass-out spray, and the ring cavity between sparge pipe and blast tube is formed as water stream channel.
4, axial water hole is opened up inside plug or in opening up axial sink, institute on plug periphery corresponding to water inlet sebific duct
State the front end of water hole or sink rear end by the water conservancy diversion water hole connection water inlet sebific duct inside connector I, water hole or the connection of sink front end
Annular space I between connector II and plug opens up the annular space between limbers connection annular space I and blast tube and connector II on connector II
II, the annular space II is connected to water stream channel.
A kind of mode of the clamping structure includes cutting ferrule, and the cutting ferrule front is installed between front housing and plug, cutting ferrule
Rear portion is locked in I front end of connector by the cooperation suit of left and right positioning pin and card slot, and left and right positioning pin radial symmetric is set to and connects
On first I, it is opened on cutting ferrule with the card slot of positioning pin contraposition, the card slot includes the locking of axial approach section and circumferencial direction
Section.
For ease of the adjusting to water, correspond to water inlet sebific duct and ball is set in I side of connector, corresponds to ball in connector
Coaxial sleeve is equipped with runoff investigation ring on I, and the inner ring convex surface of the runoff investigation ring radius linear gradient is intaking ball compressing
On sebific duct.
To prevent the leakage of sand and flow, in the hand-held shank connection of correlated parts with or mating surface between be equipped with
Sealing ring.
For ease of carrying out cleaning operation to the tooth of different parts in oral cavity, the nozzle is with 100 °~130 ° of angle
It is bent to side.
Beneficial effects of the present invention：
1, dentistry sandblasting handle of the present invention can effectively remove the soft dirt of tea stain, crock and food of dental surface by sandblasting,
It is cleaned by flow in sandblasting procedures so that the tooth for being jetted through sand is very bright and clean, and is not easy redeposited dental calculus, in teeth space
Dental calculus, bacterial plaque can also remove, thorough whitening effect is played to tooth.
2, the present invention using water, sand separation structure design and realize the sandblasting under the drive of dry gas stream, effectively keep away
The problem of having exempted from stifled sand is easy to be dismantled convenient for cleaning, sterilizing and replace even if there is of blocking up sand situation, and what is used is reliable
Property is greatly improved.
3, structure of the invention to operate simpler convenience, stability in use higher.
4, patient can be enable comfortably to experience the process of cleaning one's teeth using the present invention, without apparent feeling of pain.
