Wherein, indication mechanism is annular lamppost row, and annular lamppost is set in a row on shell, the edge of each annular lamppost
It is provided with the numerical value of an expression depth.
Compared with prior art, the hook of apex radicis dentis position indicator of the present invention is fixedly installed on shell one end, when operation, hook
When being hung on lip, shell directly hangs on hook lower section, that is, is set to patient's chin portion, grasps on one side convenient for operator
Make, checks the data information that indication mechanism is shown immediately on one side；And the length of data line is shortened, and overall work environment is more
Succinctly, the installation of equipment, using more convenient, largely avoid the generation of fortuitous event.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing apex radicis dentis position indicator.
Fig. 2 is the structural schematic diagram of invention hook formula apex radicis dentis position indicator.
Fig. 3 is the control mode schematic diagram of invention hook formula apex radicis dentis position indicator.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Fig. 2, invention hook formula apex radicis dentis position indicator includes shell 1, it is fixedly mounted on the extension of 1 one end of shell
Hook 2 is connected to the file needle 4 of 1 other end of shell by data line 5, and the control panel being set in shell 1 (does not show in figure
Out), hook 2 is hung on lip, and shell 1 directly hangs on 2 lower section of hook, and 1 surface of shell is provided with display apex radicis dentis length
Indication mechanism 6, indication mechanism 6, hook 2, file needle 4 with control panel be electrically connected.When hook 2 is hung on lip, needle 4 is filed
After being inserted into root canal, a closed circuit is formed, with deepening continuously for file needle 4, the resistance value of closed circuit also constantly becomes
Change.
One end of data line 5 is connect with control panel, and the other end is connected with file folder 3, and file needle 4 is clamped in file folder 3, is convenient for
Constantly replacement file needle 4, avoids bacterium infection.
Buzzer is installed, buzzer and control panel are electrically connected, when buzzer makes a sound, to mention in shell 1
The operator that wakes up stops the insertion of file needle, avoids causing wound and inflammation to periapex component.
Above-mentioned indication mechanism 6 is digital display screen, directly shows the insertion depth for filing needle in a manner of number and is showing
On screen.The indication mechanism 6 or LED light bar row, LED light bar are arranged in parallel on shell 1, the edge of every LED light bar
It is provided with the numerical value of an expression depth, which is gradually increased from the bottom up or from top to bottom, and continuous with file needle inserts
Enter, LED light bar lights one by one, the numerical value at the LED lamp edge finally lighted the depth that i.e. file needle is inserted at this time；Certain LED light
Item row can also be replaced with annular lamppost, and annular lamppost is set in a row on shell 1, and the edge of each annular lamppost is provided with
One indicates the numerical value of depth, and principle is arranged with above-mentioned LED light.
It is provided with displacement sensor (not shown) on above-mentioned file folder 3, for detecting the insertion depth of file needle, the displacement
Sensor and control panel are electrically connected, and the collected information of displacement sensor is transmitted to indication mechanism, will believed by control panel
Breath is reflected on indication mechanism, understands mode of operation to facilitate operation person.
Resistance measurement module, transmission module and parsing module, resistance measurement module and extension are provided on above-mentioned control panel
Hook, file needle are electrically connected, and for measuring the resistance value of above-mentioned closed circuit, transmission module is for the resistance value of measurement to be transmitted to
Parsing module is also used for the information of sensor passing to indication mechanism, and parsing module is connect with buzzer, is used for resistance value
It is compared with preset resistance value, when filing needle point arrival apical area, signal is just passed to buzzer, is brought it about
Sound reminds operator to stop continuing into file needle, at this point, numerical value, that is, apex radicis dentis length that display screen is realized.
As shown in figure 3, invention hook formula apex radicis dentis position indicator is in use, file needle is inserted into tooth root canal, with control
Then panel circuit processed connection another electrode of control circuit and hangs over the hook circuit connection on lip, forms operating circuit,
File needle issues the electric current of two different frequencies, a 8K high-frequency excitation signal and a 400Hz low-frequency excitation in tooth root canal
Signal, control panel measures two electric currents, and by the ratio of the resistance value of root canal, (ratio is not by the shadow of root canal Inner electrolysis matter
Ring), parsing module determines position of the file needle point in root canal by analyzing the ratio of more above-mentioned resistance value, and will file at this time
The data transfer of needle point position in root canal is to indication mechanism, in order to which operator checks position of the file needle point in root canal at this time
It sets, when filing needle point arrival apical area, buzzer is sounded an alarm, the numerical value shown in display screen at this time i.e. tip of a root length.
The hook of apex radicis dentis position indicator of the present invention is fixedly installed on shell one end, when operation, when being hung on lip, and shell
Body directly hangs on hook lower section, that is, is set to patient's chin portion, operates on one side convenient for operator, checks immediately on one side aobvious
Show the data information that mechanism is shown.
Finally, it should be noted that above embodiments only illustrate technical solution of the present invention, rather than its limitations；Although reference
Invention is explained in detail for previous embodiment, those skilled in the art should understand that: it still can be right
