The utility model has the advantages of simple structure, it is convenient to detect.
Description
Technical field
This utility model belongs to the technical field of tooth detection, relates to a kind of root canal length meter。
Background technology
Root canal length meter, is again electronic root tip tester, is called for short root and surveys instrument, is used to measure a kind of precision electronic device of root canal working length.Surveyed the guide of instrument by root, the sono-explorer X-ray comparing traditional can make precision higher according to measuring method, makes doctor that sono-explorer to be had and holds accurately, to accomplish perfect filling。
Summary of the invention
The purpose of this utility model is for the problems referred to above, it is provided that a kind of root canal length meter, has simple in construction, advantage easy to detect.
nullFor reaching above-mentioned purpose，This utility model have employed following technical proposal: this root canal length meter，Including fuselage，It is characterized in that，It is provided with resistance monitor in described fuselage，Described resistance monitor is connected to and chuck that corona is fixing and for detecting the detection head of resistance value between periodontal membrane and oral mucosa，Described detection head is arranged with insulation sleeve，Described detection head is provided with the displacement transducer of detection sono-explorer，Described displacement transducer is connected with the display screen on fuselage and is shown by display screen by sono-explorer，Described resistance monitor is connected to analysis module，Default resistance value it is provided with in described analysis module，When the resistance value that resistance monitor detects is more than preset value，Analysis module sends the signal of telecommunication to the alarming device in fuselage，Described alarming device sends alarm signal to user.
In above-mentioned root canal length meter, described resistance monitor is connected with display screen and analysis module respectively by resistance value output circuit.
In above-mentioned root canal length meter, described chuck includes two panels intermediate plate, and the side of every intermediate plate and teeth contact is provided with broached-tooth design.
In above-mentioned root canal length meter, described insulation sleeve adopts rubber sleeve, and described Anti-slip cover is provided with multiple anti-skidding salient point.
In above-mentioned root canal length meter, the side of described fuselage is provided with hook, and described hook is linked with the lip hook separated with gingiva by lip.
In above-mentioned root canal length meter, described alarming device is buzzer.
Compared with prior art, the utility model has the advantage of: be this phenomenon of constant (being about 6.5K ohm) according to the resistance value between periodontal membrane and oral mucosa, the resistance between periodontal membrane and oral mucosa is detected by the chuck on resistance monitor and detection head, when the resistance detected is far longer than 6.5K ohm, alarming device signal an alert, remind the detection of user sono-explorer complete, by detecting the displacement transducer on head, the length detected is shown on display screen, have easy to detect, the advantage that accuracy of detection is high, by lip hook, lip and gingiva can be separated during detection simultaneously, it is easy to the detection of sono-explorer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the root canal length meter that this utility model provides.
Detailed description of the invention
As shown in Figure 1, root canal length meter in this programme, including fuselage 1, it is characterized in that, resistance monitor 2 it is provided with in fuselage 1, resistance monitor 2 is connected to and chuck 3 that corona is fixing and for detecting the detection 4 of resistance value between periodontal membrane and oral mucosa, detection 4 is arranged with insulation sleeve 41, detection 4 is provided with the displacement transducer 5 of detection sono-explorer, displacement transducer 5 is connected with the display screen 6 on fuselage 1 and is shown by display screen 6 by sono-explorer, resistance monitor 2 is connected to analysis module 21, default resistance value it is provided with in analysis module 21, when the resistance value that resistance monitor 2 detects is more than preset value, analysis module 21 sends the signal of telecommunication to the alarming device 7 in fuselage 1, alarming device 7 sends alarm signal to user.
Resistance monitor 2 is connected with display screen 6 and analysis module 21 respectively by resistance value output circuit 22.Described chuck 3 includes two panels intermediate plate 31, and the side of every intermediate plate 31 and teeth contact is provided with broached-tooth design 32.Insulation sleeve 41 adopts rubber sleeve, insulation sleeve 41 to be provided with multiple anti-skidding salient point 42.The side of described fuselage 1 is provided with hook 11, and hook 11 is linked with the lip hook 12 separated by lip with gingiva.Alarming device 7 is buzzer.
Operation principle: be this phenomenon of constant (being about 6.5K ohm) according to the resistance value between periodontal membrane and oral mucosa, the resistance between periodontal membrane and oral mucosa is detected by the chuck 3 on resistance monitor 2 and detection 4, when the resistance detected is far longer than 6.5K ohm, alarming device 7 signal an alert, remind the detection of user sono-explorer complete, by the displacement transducer 5 in detection 4, the length detected is shown on display screen 6, have easy to detect, the advantage that accuracy of detection is high, by lip hook 12, lip and gingiva can be separated during detection simultaneously, it is easy to the detection of sono-explorer.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount the scope that appended claims is defined。
