Description
Technical field
The utility model is related to oral cavity medical apparatus, more particularly to a kind of flexible root canal appliance.
Background technology
Root canal is that to treat the diseases such as various pulpitis, pulp necrosis, fracture of tooth at present more satisfactory and ripe
Treatment method.Root canal is generally divided into five key steps；Preoperative diagnosis, the preparation of bizet and preparation, root pipe it is moulding
And cleaning（Preparation and flushing）, root pipe filling and inspection, hat side closing and check.Wherein the moulding and cleaning of root pipe, is profit
Thorough cleaning is carried out to lesion root pipe inside and root canal wall with apparatuses such as root canal files, pathological tissues are removed, moulded complete, smooth
Root tube cavity, then fill other materials, such as gutta-percha point in molded root pipe, with reach root pipe repair and treatment
Purpose.
It is the mechanical molding process for completing root tube chamber using apparatuses such as root canal files that root pipe is moulding.Current Clinical practice
Root canal file is made of metal material, such as stainless steel and Nitinol.Helical form is distributed with the work department of metal root canal file
Cutting edge, outline has certain taper, as shown in Figure 1.Root canal file is to do to rotate in root pipe with certain rotating speed during work
Motion, using cutting edge removal root pipe internal surface infected tissue, the purpose moulding to reach root pipe, while being cut using helical form
Sword discharges cutting object, as shown in Figure 2.
The root canal file rigidity that is made due to traditional metal materials is big, poor flexibility, and has certain taper, and due to root pipe one
As be in bending, so metal root canal file to realize to the cleaning of root pipe with it is moulding, generally require root pipe epimere preparation go out compared with
The changeover portion of large scale and steep-taper.These factors will cause the diameter of root canal for using the preparation of metal root canal file to be molded larger,
Root pipe has a large amount of FFI dentine tissues and is cut removal when being molded.Simultaneously because root canal file is operationally subject to alternation
Flexural deformation, usually have metal root canal file operationally because accident of the fatigue fracture in root pipe occurs.
Newest research thinks that the purpose of root canal is to repair and retain infected tooth, and can be continued
Muchly play and use function；And excessive dentine removal, the service life of tooth after treatment can be had a strong impact on, cause treatment
Rear canalis radicis dentis is too early to ftracture, and causes the tooth after treatment prematurely to lose and uses function, and this is and root canal
What purpose was disagreed.How to be removed less as much as possible in root canal without infection dentine tissue, that improves apparatus uses peace
Quan Xing, becomes the focus of current root canal appliance development.
The content of the invention
In order to solve the problems of the prior art, the utility model provides a kind of flexible root canal appliance.
The utility model provides a kind of flexible root canal appliance, including shank, work department and transition part, and the shank passes through
The transition part is fixedly connected with the work department, and the flexible root canal appliance is provided with the through hole axially penetrated through along it.
Used as further improvement of the utility model, the shank is provided with draw-in groove.
Used as further improvement of the utility model, the top of the shank is provided with connection tapering.
Used as further improvement of the utility model, the section of the shank is square, and the section of the draw-in groove is circle,
The section of the work department is any one in triangle, circle, square, rectangle, rhombus, parallelogram.
Used as further improvement of the utility model, the connection tapering is connected with flushing-liquid pipe.
Used as further improvement of the utility model, the work department is flexible working portion.
Used as further improvement of the utility model, the work department is inlaid with inorganic abradant particle.
The beneficial effects of the utility model are：By such scheme, can by tip from flushing liquid via through holes to work department
Conveying, for rinsing grinding thing, it is possible to achieve to the moulding of root bottom of the tube and cleaning, thus greatly reduce without infection dentine
Removal, be effectively improved treatment after tooth service life, reach optimal therapeutic effect.

Specific embodiment
The utility model is described in further detail for explanation and specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 3 to Fig. 7, a kind of flexible root canal appliance, including shank 1, work department 2 and transition part 3, the shank 1
It is fixedly connected with the work department 2 by the transition part 3, the axis of the flexible root canal appliance is provided with through hole 6, described logical
The flexible root canal appliance is run through in hole 6, i.e. the through hole 6 runs through the shank 1, transition part 3 and work department 2.
As shown in Fig. 3 to Fig. 7, the shank 1 is provided with draw-in groove 4.
As shown in Fig. 3 to Fig. 7, the top of the shank 1 is provided with connection tapering 5.
As shown in Fig. 3 to Fig. 7, the section of the shank 1 is square, and the section of the draw-in groove 4 is circle, the work department
2 section is any one in triangle, circle, square, rectangle, rhombus, parallelogram.
As shown in Fig. 3 to Fig. 7, the connection tapering 5 is connected with flushing-liquid pipe.
As shown in Fig. 3 to Fig. 7, the work department 2 is flexible working portion, and work department 2 is low, elastic good using elastic modelling quantity
