Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of disposable flusher.
Background technique
Perfect root canal treatment is the method for most effective treatment dental pulp disease and periapical disease.However, in root canal preparation mistake
Cheng Zhonghui generates a large amount of dentine clast, mixes with soft tissue residue, is adhered to root canal wall surface, forms smear layer.It stains
Layer is the key factor for leading to root canal treatment failure.In order to effectively remove smear layer, need to take the method for root canal irrigation.
Currently, the most common root canal irrigation method is irrigation with syringe in clinic, it is exactly by the needle point of syringe (with needle)
After the removal of other physical methods, flat use is regrinded, it is both inconvenient or be unfavorable for cleaning and sterilize.
Vertically downward because of spike bore simultaneously, medical fluid is limited under root canal at 1/3 and connection apical foramen of tooth when flushing, root canal
In, the infected material on upper 1/3 root canal wall is not easy to be cleaned.If pressure is excessive when injecting, it is easy flushing liquor
Apical foramen of tooth is released with the clast in root canal, severe complication occurs.In addition, cleaning process of the flushing needle of tip in special angle
In, it is easy to happen the case where being pierced into surrounding soft tissue, unnecessary injury is caused to patient.
Summary of the invention
In order to solve the above problems existing in the present technology, the utility model provide it is a kind of it is easy to operate, rinse thoroughly,
Use safe disposable flusher.
Purpose of the utility model is realized as follows:
Disposable flusher, it is characterised in that: the flusher includes injector and is connected in the injector
Flushing needle, the flushing needle include needle stand and the needle tubing that is connected on the needle stand, and the needle tubing front end closing is in round end shape, institute
The flushing hole symmetrical along needle tubing direction there are two setting in needle tubing front end side wall is stated, it is moveable fixed to be arranged on the needle tubing
Bit slice.
Specifically, the needle tubing front end can also be set as ellipticity.
Specifically, the cross section of the flushing hole is rectangle or arc-shaped.
Specifically, the needle tubing is straight or bending shape.
Specifically, the flushing hole number in the needle tubing front end side wall can also be set as more than two even number.
Specifically, the locating plate is made of elastic material, and the locating plate center is equipped with the location hole passed through for needle tubing.
Compared with prior art, the utility model has the following beneficial effects:
1, the flushing hole in needle tubing front end side wall is set as symmetrical along needle tubing direction, is not only able to achieve 360 degree of flushing liquor
Four wall of root canal and the flushing that moves up and down to root canal are rinsed to Omnibearing even, and flushing hole can be overcome staggeredly to divide along needle tubing
The defect of cloth is interspersed easily and the phenomenon that side water outlet other side is not discharged occurs, the effect of 360 degrees omnidirection flushing is not achieved
Fruit, especially when inject that pressure is uneven or injector in hydraulic pressure it is lower when.
2, the closing of needle tubing front end and the design without angular shape, can be avoided with the soft tissue around effective protection to trouble
The injury of person.
3, the locating plate being arranged on needle tubing facilitates the positioning of doctor to rinse.
In summary factor, disposable flusher described in the utility model, has reached more safely and effectively mesh
's.

Specific embodiment
With reference to the accompanying drawing, the utility model is described further:
Embodiment 1
As shown in Figure 1, disposable flusher, including injector 1 and the flushing needle 2 being connected in the injector 1,
The flushing needle includes needle stand 21 and the needle tubing 22 that is connected on the needle stand 21,22 front end of the needle tubing closing, the needle tubing
It is set in 22 front end side walls there are two the flushing hole 221 symmetrical along needle tubing direction, is arranged on the needle tubing 22 moveable
Locating plate 3, the needle tubing 22 are straight.
Specifically, 22 front end of needle tubing can also be set as ellipticity.
Specifically, the cross section of the flushing hole 221 is rectangle or arc-shaped.
Specifically, the flushing hole number in 22 front end side wall of needle tubing can also be set as more than two even number.
Specifically, the locating plate 3 is made of elastic material, and the locating plate center is equipped with the positioning passed through for needle tubing
Hole.
Disposable flusher described in the present embodiment, the flushing hole in needle tubing front end side wall are set as along needle tubing direction pair
Claim distribution:
On the one hand, flushing liquor 360 degrees omnidirection is able to achieve equably to rinse four wall of root canal and move up and down punching to root canal
It washes, keeps flushing more thorough, and substantially reduce flushing liquor to the flushing pressure of tooth root, the generation effectively avoided infection.
On the other hand, defect more important, that flushing hole can be overcome to be interspersed along needle tubing.Interlock when due to using
Two flushing holes of distribution are subject to hydraulic of different sizes, side water outlet other side the phenomenon that not being discharged easily occur, especially when
When injecting hydraulic lower in pressure unevenness or injector, therefore the effect of 360 degrees omnidirection flushing is just not achieved；And symmetrically divide
Two flushing holes of cloth can be completely achieved two sides while being discharged because the hydraulic size being subject to is identical, to reach 360 degrees omnidirection punching
The effect washed.
It is once washed using flusher described in the present embodiment, is arranged with a moveable locating plate on needle tubing: because of needle tubing
In use, doctor would generally first estimate the depth at lower root canal irrigation, rinse again after then carrying out bending to needle tubing, rush
The depth washed is inaccurate, and by the setting of locating plate, doctor can first measure the depth at root canal irrigation, then will determine
Bit slice slides to the depth, effectively accurate can effectively rinse.
Embodiment 2
As shown in figure 3, disposable flusher, including injector 1 and the flushing needle 2 being connected in the injector 1,
The flushing needle 2 includes needle stand 21 and the needle tubing 22 being connected on the needle stand 21,22 front end of the needle tubing closing, the needle tubing
It is set in 22 front end side walls there are two the flushing hole 221 symmetrical along needle tubing direction, is arranged on the needle tubing 22 moveable
Locating plate 3, the needle tubing 22 are bending shape.
Specifically, 22 front end of needle tubing can also be set as ellipticity.
Specifically, the cross section of the flushing hole 221 is rectangle or arc-shaped.
Specifically, the flushing hole number in 22 front end side wall of needle tubing can also be set as more than two even number.
Specifically, the locating plate 3 is made of elastic material, and the locating plate center is equipped with the positioning passed through for needle tubing
Hole.
Disposable flusher, difference from Example 1 described in the present embodiment are: the needle tubing is bending
Shape.The needle tubing opereating specification of bending shape is wide, using more convenient.
The structure, main feature, embodiment and advantage of the utility model above described embodiment only expresses, this is practical
It is novel to be not restricted to the described embodiments.It should be understood by those skilled in the art that not departing from the spirit of the present invention and model
Under the premise of enclosing, those ordinary skill in the art simply change and replace all be the protection scope of the utility model it
It is interior.
