Abstract
The utility model discloses a filing clamp for measuring the length of a root canal, of which a filing clamp connecting thread is unlikely broken and the service life is long. The filing clamp consists of a filing clamp connector, a connecting thread and a filing chuck, wherein the connecting thread is a tensile resisting thread material, and a cotton thread is clamped in a metal thread core of the tensile resisting thread material. The connecting wire used by the filing clamp for measuring the length of the root canal is unlikely to be snapped, and the service life of the filing clamp is prolonged.
Description
Technical field
This utility model relates to dental medical apparatus, particularly the measuring file folder of tooth root length of tube.
Background technology
Root canal length meter is a kind of for measuring the department of stomatology auxiliary facilities of tooth root length of tube, for helping doctor carrying out before tooth root canal, measures the physical length of tooth root pipe arrival tooth apical area.Root canal length meter is inserted into root canal file (being also " root-canal broach ") in tooth root pipe while use, then root canal file is connected with the circuit of root canal length meter main frame; Another electrode of root canal length meter main frame is connected with the lip hook circuit hanging in oral cavity.Root canal file sends the electric current of two different frequencies in tooth root pipe, and main frame is measured two electric currents by the ratio (this ratio is not subject to electrolytical impact in root pipe) of the resistance value of root pipe, determines the position of root canal file point in root pipe.When root canal file arrives when apical area, on the main frame of root canal length meter, can show in real time and give the alarm, doctor takes out root canal file measurement and enters into the physical length of tooth root pipe, just can measure tooth root pipe actual grade.
Root canal length meter need to be used the accessories such as root canal file, slotted line, file folder, lip hook and abscess probe in use conventionally, while measurement, slotted line one end is connected with main frame, two Different electrodes separated times of the other end are connected with lip hook and file folder respectively, file folder clamping root canal file extend in tooth root pipe until touch the periodontal tissue at apical foramen of tooth place, lip is hung on lip and is connected with oral mucosa, and this circuit has formed loop.On file folder, being provided with union joint carries out plug-in with slotted line and is connected, publication number is that the Chinese patent of CN2904944Y discloses " a kind of probe clip for measuring length of tooth canal ", structure to Probe clip (i.e. file folder) clamping root canal file part is described, but this patent is not described the structure of file folder connecting line.What existing file folder connecting line used is common silica gel cored wire rod, easily breaks, and service life is short.
Summary of the invention
It is not easily broken that the technical problems to be solved in the utility model is to provide a kind of file folder connecting line, the file folder that the measure the root canal length of long service life is used.
For solving the problems of the technologies described above, the file folder that the measure the root canal length that this utility model provides is used, is made up of file folder union joint, connecting line, file chuck, and described connecting line is stretching resistance wire rod.
In the metal core of described stretching resistance wire rod, accompany cotton thread.
Another kind of preferred version, is provided with web braid between the metal core of described connecting line and insulating outer layer.
The file folder that measure the root canal length of the present utility model is used has used the connecting line of stretching resistance, has added stretching resistance cotton thread in core, is provided with web braid, and connecting line is played a very good protection, and is difficult for breaking, and has extended the service life of file folder.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of embodiment of the present utility model.
Fig. 2 is the connecting line sectional view of Fig. 1 illustrated embodiment.
Number in the figure: 1, file folder union joint; 2, connecting line; 2-1 insulating outer layer; 2-2 metal core; 2-3 cotton thread; 3, file chuck.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the file folder that measure the root canal length is used is made up of file folder union joint, connecting line, file chuck, connecting line is stretching resistance wire rod, in the metal core of stretching resistance wire rod, accompanies cotton thread, between the metal core of connecting line and insulating outer layer, is provided with web braid.
Claims (2)
1. the file folder that measure the root canal length is used, is made up of file folder union joint, connecting line, file chuck, and described connecting line is stretching resistance wire rod, it is characterized in that: in the metal core of described stretching resistance wire rod, accompany cotton thread.
2. the file folder that measure the root canal length according to claim 1 is used, is characterized in that: between the metal core of described connecting line and insulating outer layer, be provided with web braid.
