Abstract
The utility model provides a kind of flexible moulding apparatus of root pipe, including shank and the flexible working portion that is fixedly connected with the shank, and the end in the flexible working portion is provided with guiding point.The beneficial effects of the utility model are：Due to flexible working portion can free bend deform the characteristics of, and the guiding function of guiding point, flexible working portion can smoothly reach crooked root tube bottom, can effectively remove in root pipe be infected tissue, complete root pipe it is moulding while, it can avoid excessively being removed without infection dentine tissue again, the service life of tooth after therapeutic effect, extended treatment can be effectively improved.
Description
Technical field
The utility model is related to oral cavity medical apparatus, more particularly to a kind of flexible moulding apparatus of root pipe.
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 is removed, moulds 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.
Moulding root pipe is the mechanical molding process for completing root tube chamber using apparatuses such as root canal files.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, root pipe internal surface infected tissue is removed using cutting edge, to reach purpose that root pipe is moulding, 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 the cleaning to root bottom of the tube with it is moulding, generally require in root pipe epimere preparation
Go out the changeover portion of large-size and steep-taper.These factors by cause using the preparation of metal root canal file shaping diameter of root canal compared with
Greatly, a large amount of FFI dentine tissues are had when root pipe is molded and are cut removal.
Newest research thinks that the purpose of root canal is reparation and retains infected tooth, and can be continued
Muchly play and use function；And excessive dentine is removed, the service life of tooth after treatment can be had a strong impact on, causes treatment
Canalis radicis dentis afterwards is ftractureed too early, prematurely loses and uses function, and this is disagreed with the purpose of root canal.How
Removed less as much as possible in root canal without infection dentine tissue, become current Endodontically treated teeth science Jiao of interest
Point.
The content of the invention
In order to solve the problems of the prior art, the utility model provides a kind of flexible moulding apparatus of root pipe.
The utility model provide a kind of flexible moulding apparatus of root pipe, including shank and be fixedly connected with the shank it is soft
Sex work portion, the end in the flexible working portion is provided with guiding point.
As further improvement of the utility model, the flexible working portion is spatially spiral structure or plane wave structure
Or linear.
As further improvement of the utility model, the flexible working portion is made up of macromolecular material.
As further improvement of the utility model, inorganic abradant particle is evenly distributed with the flexible working portion.
The beneficial effects of the utility model are：By such scheme, due to flexible working portion can free bend deformation
Feature, and the sharp guiding function of guiding, flexible working portion can smoothly reach crooked root tube bottom, can effectively remove root pipe
While interior infected tissue, completion root pipe are moulding, it can avoid excessively being removed without infection dentine tissue again, can effectively carry
The service life of tooth after high therapeutic effect, extended treatment.

Fig. 3 is a kind of schematic diagram of the flexible moulding apparatus of root pipe of the utility model.
Fig. 4 is a kind of schematic cross-section in the flexible working portion of the flexible moulding apparatus of root pipe of the utility model.
Fig. 5 is a kind of operating diagram of the flexible moulding apparatus of root pipe of the utility model.
Embodiment
The utility model is described in further detail for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Figures 3 to 5, a kind of flexible moulding apparatus of root pipe, including shank 1 and be fixedly connected with the shank 1
Flexible working portion 2, the end in the flexible working portion 2 is provided with guiding point 3.
As shown in Figures 3 to 5, the flexible working portion 2 is spatially spiral structure or plane wave structure or linear.
As shown in Figures 3 to 5, the flexible working portion 2 is that macromolecular material 4 is made, and the flexible working portion 2 is adopted
It is made of the macromolecular material that modulus of elasticity is low, elasticity is good, such as nylon, plastics, or other elastic polymer materials.
As shown in Figures 3 to 5, inorganic abradant particle 5 is evenly distributed with the flexible working portion 2, such as silica, oxygen
Change aluminium, boron nitride or diamond particles.
As shown in Figures 3 to 5, the section in the flexible working portion 2 can be circle, triangle, square, rectangle, water chestnut
Shape, parallelogram, or other shapes.
As shown in Figures 3 to 5, the flexible working portion 2 can be uiform section size vertically, it is possible to have certain
Taper.
The operation principle of a kind of flexible moulding apparatus of root pipe that the utility model is provided is：During work, flexible root pipe is moulding
Apparatus is used cooperatively with dental handpiece.Flexible working portion 2 is made up of macromolecular material 4, in macromolecular material 4
Be evenly distributed with substantial amounts of inorganic abradant particle 5, high speed rotate when, inorganic abradant particle 5 just as countless small cutting edges,
The tissue infected in root pipe is ground and removed.Again due to apparatus by be the relatively low material of modulus of elasticity be made and have guiding point 3,
The bottom of root pipe, even crooked root tube is easily entered, with the rotation and lifting of apparatus, is realized to the complete of root inside pipe wall
Clean and moulding in face.Because the modulus of elasticity of this apparatus is low, elastic and compliance is good, it is easy to reach root bottom of the tube, thus not
Need as metal root canal file, root pipe epimere need the changeover portion of large-size and steep-taper, it is possible to realize all
The cleaning of root pipe with it is moulding, thus greatly reduce without infection dentine tissue removal amount, reach optimal therapeutic effect.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to protection domain of the present utility model.
