A kind of medical root canal file, including handle and file pin are disclosed with new patent, handle is fixedly connected with file pin, the excircle of handle
Upper ring is furnished with least one integrally formed strip projected parts；A lacing hole is additionally provided with handle.
The utility model patent of Application No. 201020203645.2 discloses a kind of root canal file, and front end is blade, blade
It is fixed on by connecting portion on handle, blade is formed by the distortion of odd-shaped cross section cone, is designed with the both sides of the blade of root canal file pair
Helical edges carry out the cutting plane of cutting formation, and two cutting plane phases differ 180 °；Two, which cut pin plane, is designed as having one
Taper, its taper is consistent with the original taper of blade.
The utility model patent of Application No. 200620089851.9 discloses a kind of root canal file, including handle, in handle
One end is fixed with metal file body, and metal files body surface face covered with separating film layer, makes the metal part of metal file body not exposed, every
Thickness from film layer is 2-3 μm.
The utility model patent of Application No. 201220023702.8 discloses a kind of machine root canal file, and its front end is sword
Portion, blade is fixed on handle by connecting portion, and blade is formed by the distortion of odd-shaped cross section cone, has a ring in the connecting portion of root canal file
The groove of shape, connecting portion attenuates in the diameter of section of groove；The peak torque that groove can bear, which is less than blade, to hold
The peak torque received；Groove is located on connecting portion close to the position of handle.
The utility model patent of Application No. 200920133016.4 discloses a kind of elastic root canal file, by work department and handle
Portion is constituted, it is characterised in that symmetrical structure centered on the section of the work department, is provided with rear side of the cutting edge of the work department
Broadband, the angular range of work department cutting anterior angle is between 0-25 spend；The centrosymmetric structure in the work department section be three,
4th, five or six subcenter symmetrical structure, the work department has 3,4,5 or 6 head thread structures；The taper of work department is single cone
The combination of degree or more than 2 tapers, its range of taper is between 2% -12%；After the helical angle of the work department front end is more than
The helical angle at end；The work department and shank are formed in one structure or combined connecting structure；The work department is NiTi elasticity
Alloy, stainless steel or nonmetallic materials structure.
The work department of root canal file includes connecting rod and blade, because root pipe is that bending is irregular in itself, it is therefore necessary to protect
There is card work department toughness can bend, and blade and connecting rod are all integrally formed, therefore connecting rod and blade are all with tough
Performance is enough bent.
And in actual mechanical process, work department at the connecting rod bend, cause sword under the induced effect of motor
The tail end amplitude of fluctuation in portion is larger, is unfavorable for the cleaning of root pipe, causes the root canal time long.
Utility model content
The utility model in order to solve existing root canal file because bent at connecting rod cause blade tail end amplitude of fluctuation
The problem of cleaning of root pipe is slow caused by degree is larger, and a kind of root canal file is provided, in endodontic procedure, sword can be reduced
The amplitude of fluctuation in portion, improves the cleaning efficiency of root pipe, so as to reduce the time of root canal.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of root canal file, including handle, the handle are connected with work department, and the work department includes connecting rod and blade,
The blade is connected through connecting rod with handle, it is characterised in that the toughness of the connecting rod is less than the toughness of blade.
The connecting rod is made by austenitic titanium alloy, and the blade is made by martensite Nitinol.
The screw thread of the blade is machined into by martensite Nitinol, and the section of the blade is in quadrangle.
The quadrangle is square or rectangle.
Silica gel indicating piece is arranged with the connecting rod.
The connecting rod is provided with least two circular scale line.
Compared with prior art, the utility model has the advantages that：
Root canal file of the present utility model, including handle, the handle are connected with work department, and the work department includes connecting rod
And blade, toughness of the toughness less than blade of the connecting rod.The toughness of connecting rod of the present utility model is less than the toughness of blade,
During root pipe is treated, because the toughness of blade is better than the toughness of connecting rod, it is possible to increase the centralized positioning energy filed with pipe
Power, reduces apical transportation, reduces the risk of fracture, therefore is bent in the presence of external force since blade, so that will be low
