Description
Technical field
The utility model is a kind of combined type root canal moulding instrument, is related to medical instrument, is especially applied to various dental pulps
It is used when the root canal treatment and filling of inflammation, pulp necrosis, fracture of tooth etc..
Background technique
Root canal treatment is that treat the diseases such as various pulpitis, pulp necrosis, fracture of tooth at present more satisfactory and mature
Treatment method.Root canal treatment is generally divided into five key steps；Preparation and preparation, the moulding of root canal of preoperative diagnosis, bizet
With cleaning (preparation and flushing), the filling of root canal and inspection, the closing of hat side and check.
The wherein moulding and cleaning of root canal is carried out thoroughly to inside lesion root canal with root canal wall using root canal moulding instrument
Cleaning removes pathological tissues, moulds the process of complete, smooth root canal inner cavity.Other materials are filled in molded root canal
Material, such as gutta-percha point, to achieve the purpose that root canal reparation and treatment.
The root canal moulding instrument of clinical use is all made of metal material and is made at present, such as stainless steel or Nitinol.Metal
Helical cutting edge is distributed in the work department of root canal file, outer profile has certain taper, as shown in Figure 1.Shaping device when work
Tool is made rotating motion in root canal with certain revolving speed, root canal inner surface infected tissue is removed using cutting edge, to reach root canal
The purpose of moulding, as shown in Figure 2.
The disadvantages of there are rigidity for traditional metal root canal moulding instrument greatly, poor flexibility.
The root canal moulding instrument rigidity as made of traditional metal materials is big, poor flexibility, and has certain taper, and due to
Root canal generally generally requires so metal moulding instrument will realize the cleaning and moulding to root canal bottom in root canal in bending
Upper section preparation goes out the changeover portion of larger size and steep-taper.These factors will lead to using metal moulding instrumentation molding
Pipe diameter is larger, has a large amount of uninfected dentine tissues in root canal molding and is cut removal.Current research thinks, root canal
The purpose for the treatment of is reparation and retains infected tooth, and can continue muchly to play using function, and excessive
Dentine removal, can seriously affect the service life of tooth after treatment, and the canalis radicis dentis after leading to treatment is premature to crack, and control
Tooth after treatment prematurely loses using function, this is disagreed with the purpose of root canal treatment.How to be use up in root canal treatment
Possibly few removal becomes current Endodontically treated teeth Institute of Science focus of attention without infection dentine tissue.
Utility model content
The purpose of the utility model is to provide a kind of combined type root canal moulding instruments, while having cutting force and elastic force concurrently.
A kind of combined type root canal moulding instrument, including handle 1 and work department 2, the work department 2 and handle 1 are fixedly connected on
Together, it is characterised in that: work department 2 is combined by high molecular material 3 and metal core wire 4, wherein high molecular material 3 coats
Outside metal core wire 4；In high molecular material 3, inorganic abradant particle 5 is also distributed with.
The high molecular material 3 is nylon, the material that plastics or other elasticity modulus are low, elasticity is good；The metal
Core wire 4 is made of elastic stainless steel silk or superelastic nickel-titanium alloy wire；The inorganic abradant particle being distributed in high molecular material is
Silica, aluminium oxide, boron nitride or diamond particles.
The cross section of the metal core wire 4 is circular, square, triangle or other regular polygons.
The work department 2 along axial direction is cross-section size or tapered.
The inorganic abradant particle 5 is generally evenly distributed in high molecular material 3, or is evenly distributed on work department 2
Surface layer.

It is securely joined together.
The utility model has the advantages that
When work, the utility model is used cooperatively with dental handpiece.The work department of the utility model is low by elasticity modulus, bullet
Property good high molecular material and super-elastic metal Material cladding form, thus there is fabulous flexibility, it is easy to enter root canal
Bottom, even curved root canal.While keeping effectively removing infected tissue in root canal, completing root canal moulding,
It can avoid excessively being removed without infection dentine tissue again, therapeutic effect can be effectively improved, the use of tooth after extended treatment
Service life.
Again due to being distributed a large amount of inorganic abradant particle, these particles in the high molecular material in devices work portion
There can be grinding function to root canal inner wall.With the high speed rotation and lifting of instrument, the comprehensive moulding of root canal inner wall is realized.
Since the elasticity modulus in devices work portion is low, flexibility is good, group is infected in root canal keeping effectively removing
It while knitting, complete root canal moulding, and can avoid excessively being removed without infection dentine tissue, treatment effect can be effectively improved
Fruit, the service life of tooth after extended treatment.
Since the elasticity modulus in devices work portion is low, flexibility is good, it may not be necessary to go out large scale in root canal upper section preparation
With the changeover portion of steep-taper, so that it may realize the moulding and cleaning to root canal bottom, thus greatly reduce without infection dentine
Removal, effectively improve treatment after tooth service life, reach optimal therapeutic effect.
