Description
Technical field
A kind of department of stomatology canalis radicis dentis cleaning file of the present invention is related to one kind in oral cavity progress endodontic procedure, to root pipe
The foreign matter treated in canalis radicis dentis carries out clean device, belongs to medical instruments field.More particularly to one kind curls on the guide bar
Helical structure, rotation removing carried out to the foreign matter in canalis radicis dentis, and dress is filed by the cleaning that the contraction of screw rod is discharged
It sets.
Background technology
Currently, being damaged after death in tooth dental pulp, need to carry out root canal to tooth, when carrying out root canal, need
Marrow is first carried out out, dental nerve is killed, the dental nerve in root pipe is then cleared up, lesion pulp tissue is removed, is then filled out
It fills, the root pipe of infection mainly has the dental pulp of necrosis and remaining vital pulp tissue, and the product of metabolism, is carrying out root pipe
When inner wall cleans, due to forming coarse crumb layer inside root pipe, root pipe can be blocked, causes root pipe that can not fill, it is therefore desirable to
Crumb layer is cleared up, is all to be cleaned using passive rinse of cleaning file cooperation at present, by cleaning file in root of the tooth
Then wall friction in rotation and root of the tooth coordinates syringe needle to be washed away, cleaning is poor, and repetitious cleaning is needed to get to want
It asks, especially the narrow regions at root canal point end, cooperation sometimes is actively cleaned, by root pipe when actively cleaning
Interior liquid applies energy and is cleaned, and mostly uses supersonic cleaning, but ultrasonic cleaning is more demanding, careless slightly to will appear
Step or side are worn, and cleaning effect is poor, existing cleaning file needed when being cleaned it is larger by space, cannot and root of the tooth
Inside pipe wall is preferably bonded,
It is open（Bulletin）Number CN105662607A discloses a kind of pipe cleaning file and its clean method, including：Handle and file body,
The handle with file body fixed-link, it is described file body tip be provided with guiding point, using need coordinate dental handpiece, the cleaning file
For elastic construction, can be bent, it is flexible larger, it is fixed it is difficult to support occur, cleaning file is susceptible to when being stretched into
Bending is shunk, designated position can not be reached, and needs that flusher progress foreign matter is coordinated to wash away after having cleaned, efficiency is low, cleaning
It is not thorough, the interim discharge of foreign matter cannot be directly carried out by revolving the spiral of cleaning file.
Invention content
In order to improve the above situation, a kind of department of stomatology canalis radicis dentis cleaning file of the present invention provides one kind and curls on the guide bar
Helical structure, rotation removing carried out to the foreign matter in canalis radicis dentis, and dress is filed by the cleaning that the contraction of screw rod is discharged
It sets.
A kind of department of stomatology canalis radicis dentis cleaning file of the present invention is realized in：A kind of department of stomatology canalis radicis dentis cleaning file of the present invention
By casing, fixed arm, guide rod, spiral file, fixed ring, connector sleeve, sliding groove, limiting plate, mobile push plate, topping and hollow
Pipe forms, and connector sleeve is placed on one end of guide rod, and spiral file is placed on guide rod, and one end is curled by fixed ring
It is placed on the outer wall of connector sleeve, the guide rod is bourdon tube, and the spiral file is cone helical structure, and the spiral of one end is partly
Diameter is minimum, and the spiral file is made of hollow tube and multiple toppings, topping along hollow pipe outer wall at circle distribution, and in
Blank pipe is axially extending, and fixed arm is symmetrically placed on the guide rod other end, and perpendicular with guide rod, and casing is placed on guide rod
On, two sliding grooves are symmetrically placed on casing, and axially extending along casing, and fixed plate correspondence is placed in sliding groove, compresses bullet
Spring is placed in casing, and is located at fixed plate side, and one end of casing and the spiral file other end are connected and fixed, and spiral file
The axis co-axial of the axis of screw and guide rod, mobile push plate are placed on casing, and far from guide rod one end, limiting plate is placed in casing
On, and far from guide rod one end.
In use, the compressed spring in original state casing pushes fixed arm so that casing and fixed arm distance are farthest, set
Pipe stretches spiral file so that spiral file is close to close on the guide bar so that the section of spiral file is minimum, then medical care
Human hand pinches casing, and fixed ring is extended inwardly into along canalis radicis dentis, when reaching designated depth, will hold the position of handle into
Row is fixed, and then pushes casing by external force so that casing is slided along guide rod, and compressed spring is pressurized, and fixed arm is to casing
Guide and limit is carried out, the mobile drive spiral file of casing resets, and forms cone helical structure and the fitting of root of the tooth pipe surface, then
Force is carried out by limiting plate and drives sleeve rotating, and sleeve rotating drives the spiral file other end to be rotated, while guide rod
Drive the rotation of spiral file one end so that spiral file is integrally rotated, and is cleaned to root of the tooth inside pipe wall, by the different of inner wall
Object cleaning falls off, and then unclamps casing, and compressed spring pushes casing along guide rod reverse slide, and casing pulls spiral file
It is exceptionally straight, in spiral file pulls moving process, the foreign matter under grinding is taken out of in canalis radicis dentis, carries out interim discharge, avoids
In grinding, foreign matter is squeezed along the rotation of spiral file and is attached on canalis radicis dentis again, then pushes casing again, make
The extension of spiral file and canalis radicis dentis fitting are obtained, grinding cleaning is carried out, when carrying out grinding process, spiral file and root of the tooth inside pipe wall
Frictional vibration so that hollow tube generates vibration, and vibration stripping is carried out to root of the tooth inside pipe wall foreign matter,
The cone helical design of the spiral file enables to spiral file to meet the structure of canalis radicis dentis taper, more holds in cleaning
It is easy to attach；
The design of the guide rod provides support force when spiral file is cleaned, for spiral file so that spiral file can
Designated depth is reached, avoids spiral file from encountering protrusion on root of the tooth inner wall and change direction, influences cleaning effect；
Described sleeve pipe can cooperate between guide rod, spiral file so that spiral file is when entering canalis radicis dentis, spiral
File can be bonded with guide rod, and reduce spiral file passes through section；
The guide rod, which is the design of bourdon tube, can avoid when encountering protrusion, be capable of providing retraction space, avoid directly touching
It hits and brings pain；
Achieve the purpose that canalis radicis dentis cleaning discharge.
Advantageous effect.
One, simple in structure, it is convenient and practical.
Two, the cleaning quality of canalis radicis dentis intraclast layer can be improved.
Three, cleaning file depth can be avoided insufficient, cleaning is not thorough.
Four, the percent of pass of cleaning file can be improved.
