Description

A kind of dental root canal flushing needle

Technical field

This utility model relates to technical field of oral medicine, particularly relates to a kind of dental root canal flushing needle.

Background technology

In the department of stomatology, root canal is one of most popular method in tooth body dental pulp, periodontal diagnosis and treatment, wherein root canal irrigation is indispensable step, flushing tool conventional is at present common needles formula syringe, there are the following problems: 1, rinse time grinding one's teeth in sleep in rear portion and use inconvenience, especially crooked root tube, inconvenience is inserted, easily stab oral soft tissue, and syringe needle is twisted and warped by some doctors, syringe needle mill, like this, the blocking in duct can be caused, flushing dose is reduced, and manufacturing process wastes time and energy, also can cause iatrogenic pollution.2, needle tubing is only at front opening, and flushing liquor is linearly gone out, and rinses direction single, and be subject to root canal wall and stop, developing result is poor; If syringe needle to be inserted root pipe deep, easily form excessive pressure at root tip, can dentin chip, antibacterial and pathologic product thereof etc. in root canal are flushed to outside apical foramen of tooth, cause patient to have an intense pain and the inflammation secondary of organization of root tips and damage; Some doctors can grind some side openings on the leaning to one side of injection needle, but due to needle tubing lack tapering, can not bend, to grind side opening not of uniform size, not only easily blocking occur and affect developing result, and manufacturing process is not easily controlled, the danger that when also can cause use, the needle body fractures.3, in root canal irrigation process, need repeatedly to extract flushing liquor, and the pressure of flushing liquor is relatively little, reduces the work efficiency of operator.4, in the post crown restoration process after tooth finishes root canal, be difficult to the etching agent in driven pile road thoroughly to remove clean and affect the effect of post crown restoration.5, in root canal irrigation, conventional flush syringe needle also easy needle stand install closely time accidental, thus the danger causing patient by mistake to gulp down.

Summary of the invention

The purpose of this utility model is the deficiency overcoming above-mentioned technical method, and provide a kind of simple and easy to do, developing result is good, the dental root canal flushing needle that safety is high.

In order to achieve the above object, the solution that this utility model is taked is: a kind of dental root canal flushing needle (see figure 1), comprise needle stand (1), gas-liquid mixed chamber (2), band side opening looper pipe (3), needle tubing side opening (4), anticreep is fastened (5), anti-off-line (6), Anti-release clamp (7), wherein, tip with side opening looper pipe 3 is closure designs, as shown in Figure 2, mainly for the flushing of root pipe in endodontic procedure, rinse as needed tip inlets, tip can be cut off and expose duct a little, especially for the flushing of etching agent in post crown restoration king-pile road preliminary procedure.

Needle stand 1 surface is provided with the anti-slip veins of circular arc projection, and when being convenient to be enclosed within three-gun tube mouth, medical personnel's hand is affectedly bashful and reinforcing.The design in gas-liquid mixed chamber 2 is for making the gas sprayed in three-gun tube mix more fully with liquid.In addition, whole root canal flushing needle is made up of elastomeric material, and so, needle tubing can do torsion to a certain degree, and reaches evenly effective developing result, and needle tubing side opening design feature is more and more closeer to needle point directional spreding from bending part, more and more less.

Anti-off-line one end is connected to anticreep and fastens hole, and one end connects with Anti-release clamp, for the resistance to high hot material of toughness is made, and use of can repeatedly sterilizing.Anti-release clamp is a cross section is 3/4 arc structure, its interior diameter and the department of stomatology now match with three rifle head overall diameters of standard care chair, for the detachable maintenance that connects, there is anti-slip veins in the outside at " C " type Anti-release clamp two ends, be made up of elastomeric material, utilize itself elasticity to a certain degree, be stuck on three-gun tube, play maintenance effect.

This utility model compared with prior art has following beneficial effect: root canal flushing needle is connected with three rifles in dental treatment chair, and by its gas-liquid power, rinse great efforts, pin hole not easily blocks, simple and easy to do; Needle tubing has certain camber and band side opening, and developing result is good; Torsion to a certain degree can be done, be easy to the flushing of rear portion molars root canals; Have Anti-release clamp protection not easily to make patient gulp down, safety is high by mistake.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, this utility model is further illustrated.

Fig. 1 is the structural representation of dental root canal flushing needle of the present utility model;

Fig. 2 is the band side opening looper tip portion closure designs schematic diagram of dental root canal flushing needle of the present utility model.

Detailed description of the invention

Now by reference to the accompanying drawings 1, 2, the detailed description of the invention of this dental root canal flushing needle is explained as follows: for the root canal irrigation in root canal, its Anti-release clamp 7 is fixed on nearly valve one end of three-gun tube, afterwards needle stand is tightly inserted in outside three rifle heads, wash from three rifle heads in case Gas fluid pressure crosses senior general's flushing needle and cause danger, press the gas of three rifles more simultaneously, Liquid valve, gas liquid mixture will enter from 1, band looper pipe 3 is entered behind gas-liquid mixed chamber 2 fully mixing, after go out from its side opening 4, now to check whether flushing needle blocks, whether the elasticity of needle stand is suitable, can be inserted into after errorless in the root pipe for preparing in patient oral cavity and rinse, and coordinate go out thing with the timely sucking-off oral cavity of use of inhaling saliva device.As curved pipe, because this dental root canal flushing needle is elastomeric material, the torsion done to a certain degree of can taking advantage of a situation.In addition, for the flushing in post crown restoration pile road or the flushing of periodontal, available shears is cut off flushing needle tip and is exposed duct a little, afterwards using method and closure designs similar.

According to specific exemplary embodiment, this utility model is described herein.Suitable replacement is carried out or amendment will be apparent not departing to one skilled in the art under scope of the present utility model.Exemplary embodiment is only illustrative, instead of the restriction to scope of the present utility model, and scope of the present utility model is defined by appended claim.
