Abstract

The invention provides a root canal cleaning file and a cleaning method thereof. The root canal cleaning file comprises a handle and a file body, the handle and the file body are fixedly connected, and a guide tip is arranged at the pointed end of the file body. The root canal cleaning file has the advantages that the hardness of the material of the cleaning file is low so that a shaped root canal can not be damaged, the surface of the inner wall of the root canal is subjected to cleaning similar to grinding and polishing, a dirty layer generated when the root canal is shaped can be effectively removed, and final cleaning of the root canal is achieved.

Description

A kind of root pipe cleaning file and clean method thereof

Technical field

The invention belongs to field of oral cavity medical equipment, relate to a kind of root pipe cleaning file.

Background technology

Root canal is to treat the Therapeutic Method that the diseases such as various pulpitiss, pulp necrosis, gangrene, fracture of tooth are more satisfactory and ripe at present. Root canal is generally divided into five key steps; Preoperative diagnosis, the preparation of bizet and preparation, the cleaning of root pipe and moulding (rinsing and preparation), the filling of root pipe and inspection, hat side close and check. Wherein root pipe cleaning and moulding be in root pipe, remove pathological changes pulp tissue etc., prepare the Configuration needed for meeting requirements on three-dimensional close packing simultaneously, be the committed step of therapeutic process.

Include 1 in the root pipe infected, microbial infection and metabolite thereof; 2, pulp tissue, including downright bad or vital pulp tissue; 3, biomembrane. Remove these be root pipe moulding time the target mainly cleared up. Root pipe is moulding is utilize the apparatuses such as root canal file, and what mechanical type completed root tube chamber moulds electric process. Moulding about root pipe, the theory of current existed system and the operating procedure of specification, and efficient training equipment. But while root pipe is moulding, coarse surface can be formed at root inside pipe wall and be attached to the crumb layer of inwall, also referred to as staiing layer. Stain layer and can block collateral pulp canal, cause that collateral pulp canal cannot be filled. Can not completely remove if staiing layer, the mortality causing treatment being improved and the increase of unnecessary complication, directly affects therapeutic effect.

About the cleaning of root pipe, currently mainly means is chemical flush. Backwashing manner has passive flushing and positive flush two kinds. So-called passive flushing, refers to the backwashing manner that cleanout fluid repeatedly injects root tube chamber with syringe needle, and the cleaning effect of this mode is generally difficult to obtain satisfied effect, the especially narrow zone of root canal point end; Positive flush refers to, in root pipe, liquid is applied certain energy, makes cleanout fluid produce hydrodynamics and changes, thus reaching sterilization, cleaning the purpose of root pipe, as ultrasonic swinging is washed. But use ultrasonic swing wash time, do not allow ultrasonic instrument to encounter any position of root pipe, step or side otherwise can be caused to wear, destroy moulding root pipe. No matter which kind of backwashing manner, all cannot be satisfied with removal and stain layer.

Summary of the invention

In order to solve above technical problem, the present invention provides a kind of cleaning file for root pipe cleaning, can effectively remove moulding after the contamination layer of root pipe internal surface, be greatly improved the success rate for the treatment of.

The present invention provides a kind of root pipe cleaning file, including: handle and file body, described handle and file body fixed-link, the tip of described file body is provided with guiding point.

Preferably, described file body employing hardness ratio elastomeric material relatively low, that elastic modelling quantity is low is made, such as Nitinol, nylon, plastics, or other elastic polymer material.

Preferably, described file body structure adopts spatially spiral structure or plane wave structure, in order to contact with the effective of root canal wall stretching into root Guan Houke realization file body.

Preferably, the cross section of described file body adopts the one in circle, triangle, square, rectangle, rhombus and parallelogram.

The present invention also provides for the clean method of a kind of pipe cleaning file, including following step:

Step A: cleaning file with dental handpiece with the use of, described guidance tip stretches into the bottom of root pipe;

Step B: owing to cleaning file has certain elasticity, after stretching into root pipe, with the constraint of root pipe, cleaning file has some positions and is close to root canal wall;

Step C: along with rotation and the lift of cleaning file, it is achieved that comprehensive cleaning of root inside pipe wall.

Wherein, dental handpiece is a kind of standard device, and use is to insert handle in mobile phone just may be used.

The workflow of the present invention is: cleaning file with dental handpiece with the use of. Owing to cleaning file is made up of the material that elastic modelling quantity is relatively low, and there is guidance tip, it is easy to stretch into the bottom of root pipe or even the root pipe of bending. Owing to cleaning file has certain elasticity, after stretching into root pipe, with the constraint of root pipe, cleaning file has some positions and is close to root canal wall. Rotation and lift along with cleaning file, it is achieved that comprehensive cleaning of root inside pipe wall.

The invention have the benefit that owing to the hardness ratio of cleaning file material is relatively low, moulding good root pipe will not be damaged, but can the inner wall surface of root pipe being polished and cleaning, the contamination layer produced when making root pipe moulding is effectively removed, it is achieved that the last cleaning of root pipe.

Accompanying drawing explanation

Fig. 1 is root pipe cleaning file structure chart in the present invention.

Fig. 2 is root pipe cleaning file fundamental diagram in the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the preferably embodiment of the present invention is described in further detail:

Embodiment 1

As it is shown in figure 1, a kind of root pipe cleaning file, being made up of handle 1, file body 2, handle 1 and file body 2 fixed-link, most advanced and sophisticated at file body, processing has guiding point 3, such as Fig. 1.

File body adopts hardness ratio is relatively low, elastic modelling quantity is low elastomeric material to make, such as Nitinol, nylon, plastics, or other elastic polymer material.

File body structure can be spatially spiral structure, or plane wave structure.

The cross section of file body can be circle, triangle, square, rectangle, rhombus, parallelogram, or other shape.

During work, cleaning file with dental handpiece with the use of. Owing to cleaning file is made up of the material that elastic modelling quantity is relatively low, and there is guidance tip, it is easy to stretch into the bottom of root pipe or even the root pipe of bending. Owing to cleaning file has certain elasticity, after stretching into root pipe, with the constraint of root pipe, cleaning file has some positions and is close to root canal wall. Rotation and lift along with cleaning file, it is achieved that comprehensive cleaning of root inside pipe wall. Owing to the hardness ratio of cleaning file material is relatively low, moulding good root pipe will not being damaged, but can the inner wall surface of root pipe be polished and cleaning, the contamination layer produced when making root pipe moulding is effectively removed, it is achieved that the last cleaning of root pipe.

Above content is in conjunction with concrete preferred implementation further description made for the present invention, it is impossible to assert that specific embodiment of the invention is confined to these explanations. For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, protection scope of the present invention all should be considered as belonging to.
