Abstract

The utility model provides a clean file of root canal, include: the handle and the file body, handle and file body fixedly connected, the pointed end of the file body is provided with the guide point. The beneficial effects of the utility model are that: the during operation, clean file uses with the dental handpiece cooperation. Because clean file is made by the lower material of elastic modulus to there is the guide most advanced, stretches into the bottom of root canal very easily, or even crooked root canal. Because clean file has certain elasticity, after stretching into the root canal, owing to there is the restraint of root canal, clean file is understood some position and is hugged closely the root canal wall. Along with the rotation of clean file with carry and drawing, comprehensive cleanness of root canal inner wall has been realized.

Description

A kind of root pipe cleaning file

Technical field

This utility model 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 (rinse and prepare), 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 met needed for three-dimensional close packing simultaneously, be the committed step of therapeutic process.

1, microbial infection and metabolite thereof is included in the root pipe infected；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 to 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 stain layer.Stain layer and can block collateral pulp canal, cause collateral pulp canal to fill.If staiing layer can not remove completely, 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 repeatedly be injected by cleanout fluid the backwashing manner of root tube chamber with syringe needle, and the cleaning effect of this mode is typically 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 reaches sterilization, the purpose of cleaning 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 the most moulding root pipe.No matter which kind of backwashing manner, all cannot be satisfied with removal and stain layer.

Utility model content

In order to solve above technical problem, this utility model 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.

This utility model 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, the one during described file body uses Nitinol, nylon and plastics.

Preferably, described file body structure uses spatially spiral structure or plane wave structure.

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

The beneficial effects of the utility model are: 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, the root pipe even bent.Owing to cleaning file has certain elasticity, after stretching into root pipe, owing to there being the constraint of root pipe, cleaning file has some positions and is close to root canal wall.Rotation and lifting along with cleaning file, it is achieved that comprehensive cleaning of root inside pipe wall.

Accompanying drawing explanation

Fig. 1 is root pipe cleaning file structure chart in this utility model.

Fig. 2 is root pipe cleaning file fundamental diagram in this utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings, preferably embodiment of the present utility model is described in further detail:

Embodiment 1

As depicted in figs. 1 and 2, a kind of root pipe cleaning file, it is made up of handle 1, file body 2, handle 1 and file body 2 fixed-link, most advanced and sophisticated at file body, it is machined with guiding point 3.

File body uses 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, the root pipe even bent.Owing to cleaning file has certain elasticity, after stretching into root pipe, owing to there being the constraint of root pipe, cleaning file has some positions and is close to root canal wall.Rotation and lifting 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, the most moulding good root pipe will not be damaged, but the inner wall surface of root pipe can carry out similar cleaning as grinding and polishing, and 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 to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.

Claims

1. a root pipe cleaning file, it is characterised in that including: handle and file body, described handle and file body fixed-link, the tip of described file body is provided with guiding point；Described file body structure uses spatially spiral structure or plane wave structure.

2. root pipe cleaning file as claimed in claim 1, it is characterised in that described file body uses the one in Nitinol, nylon and plastics.
