Description
Technical field
The utility model is related to medical instruments field, specifically refers to a kind of root cap cell file of external graduated scale.
Background technology
Electronic Apex Locator is that oral medicine carries out the conventional medicine equipment of root canal, and its principle is surveyed by electronic instrument
Root pipe internal impedance changing rule is measured to determine live body foramen apicis dentis position or sono-explorer.Cheek retractor is hung over into mouth when using
Angle, is then held with root pipe holder and sets aside the vernier above filing expanding needle behind slow insertion root pipe, in-position after root-canal broach
To cusp or incisxal edge, then the distance for measuring needle point to rubber lower edge with small ruler is the active length of root pipe.But in root pipe
In therapeutic process, filing expanding needle is removed to measure root canal working length, vernier easily shift the problems such as need to remeasuring length without
Doubt and add workload, extend the clinical manipulation time.
Utility model content
The purpose of this utility model, which is to provide one kind to be circumscribed with graduation apparatus and can be inserted directly into after root canal file, just to be read
Number, avoid the risk that can not accurately be measured because vernier is easily shifted, and root cap cell file simple in construction, easy to use.
The utility model is achieved through the following technical solutions：A kind of root cap cell file of external graduated scale, including root canal file
With the graduation apparatus being socketed on root canal file, the root canal file includes handle and frustrates pin, the expansion with the expansion for being connected to lower portion thereof
Frustrate and vernier is cased with pin, the vernier is connected by graduation apparatus with handle.The present apparatus is filled using scale is cased with root canal file
Put to realize the function of measurement length, general root canal file can only be positioned after insertion tooth root pipe using vernier then takes out reading
Number, because whole root canal file stock size is smaller, operating personnel are easy to cause to survey because of misoperation when using root canal file
Amount is inaccurate, once sono-explorer can not be measured accurately, can bring certain trouble to follow-up treatment.Then for
Overcome this problem, the graduation apparatus for being used for measuring just is provided with outside root canal file, and graduation apparatus connects vernier and handle, leads to
Cross after the clearance distance between measurement vernier and handle, then frustrate with expansion pin length and subtract vernier and move down distance and just obtain root pipe
Length, and this measuring process can root canal file insertion root pipe in just can carry out, without again removing root canal file, reduce
Operating procedure, also improves measurement accuracy, and accurate data is provided for follow-up treatment.
Preferably to realize the utility model, further, the graduation apparatus includes sleeve pipe and graduated scale, described sleeve pipe
Upper end is connected with handle, and the graduated scale inserts and passes sleeve pipe and is connected with vernier.Described graduation apparatus be connection handle and
Vernier, that is, sleeve pipe is arranged on handle side, and the lower end of graduated scale is flexibly connected with the side wall of vernier, graduated scale
Length is less than the length of whole root canal file, to operate graduated scale with operating personnel.
Further, headgear is connected with the outside of described sleeve pipe upper end, the headgear is socketed on handle.It is provided with sleeve pipe
For covering the headgear of connecting handle, so as to realize being flexibly connected for whole graduation apparatus and root canal file, and graduated scale with vernier to live
Dynamic connection disassembling in order to graduation apparatus, because general root canal file small volume, service life is not long, using several times
Root canal file is just changed afterwards, and graduation apparatus is then set to the structure that conveniently can disassemble and change to improve adaptability.
Further, the minimum scale on the graduated scale is 0.5 or 1mm.Namely graduated scale is provided with spacing distance
For 1mm long graduation mark, or provided with the short graduation mark that spacing distance is 0.5mm.Be connected with vernier when graduated scale lower end, vernier
When frustrating pin top positioned at expansion, the reading of graduated scale is 0mm, and the maximum range Ying Yukuo of graduated scale frustrates pin similar length to carry
High measurement scope, in measurement, when vernier is moved downward and reaches measuring point, operating personnel should be since graduated scale the top
Reading, now whole graduated scale extension elongation be just equal to the downward displacement of vernier.
Further, the graduated scale is 0.8 ± 0.01mm of diameter steel wire, and described sleeve pipe internal diameter is 0.7 ± 0.01mm.
The internal diameter that the diameter of described graduated scale is more than sleeve pipe is in order to having certain frictional force between graduated scale and sleeve pipe, pass through mistake
Cooperation of being full of can increase certain damping so that vernier can keep relative position constant.
Further, the headgear is ring-shaped sleeve structure, and the material of headgear is rubber.Described ring-shaped sleeve structure energy
It is enough to be directly connected on handle outer wall, and come off on headgear inwall provided with non-slip texture so as to prevent headgear from fixing unstable
Phenomenon occur.And use quality of rubber materials to improve frictional force also for further.
Further, the vernier material is also rubber.It is equal that pin diameter is frustrated in the internal diameter of described vernier and expansion, and vernier
Using quality of rubber materials also for the certain damping of increase, it is to avoid vernier slides unstable influence measurement accuracy in positioning, and swims
Target internal diameter frustrated with expanding pin diameter it is equal be to cause vernier to be difficult to move in order to avoid excessively clamping is close, so vernier with
The damping that pin outer wall is frustrated in expansion will be controlled in suitable scope consequently facilitating measuring.
Further, the material that pin is frustrated in the handle and expansion is stainless steel.
The utility model compared with prior art, with advantages below and beneficial effect：
（1）The utility model by be circumscribed with graduation apparatus so that root pipe measuring process and can be inserted in root canal file
It just can be carried out in root pipe, and need to change big model in root canal preparation without active length is determined repeatedly, subtracted
Operating procedure is lacked, has also improved measurement accuracy, accurate data is provided for follow-up treatment；
（2）The utility model is in order to graduated scale and set by the way that the diameter of graduated scale to be set greater than to the internal diameter of sleeve pipe
There is certain frictional force between pipe, certain damping can be increased by interference fit so that vernier can keep relative position
It is constant；
（3）The utility model by vernier by being set to quality of rubber materials also for the certain damping of increase, it is to avoid vernier
Unstable influence measurement accuracy is slided in positioning, and quality of rubber materials is also corrosion-resistant, and also oral cavity will not be caused harm, and be manufactured into
This is relatively low.
