Abstract
The utility model provides a measuring scale for a working length of a root canal file. The scale comprises a measuring scale body; the measuring scale body is provided with a display, a switch button and a measuring groove; one end of the measuring groove is provided with a displacement sensor, and the center of the measuring groove is provided with a block. The overall length of the measuring groove is larger than the length of the root canal file. A distance from the displacement sensor to the block is larger than the working length of the root canal file. The width of the measuring groove is larger than the width of a handle of the root canal file. The measuring scale body is internally provided with a microprocessor. An output end of the displacement sensor is connected with an input end of the microprocessor, and an output end of the microprocessor is connected with the display. With the adoption of the structure of the measuring scale, an old doctor is enabled to read a mark quickly when measuring the working length of the root canal file, and operation is facilitated.
Description
Technical field
The utility model belongs to department of stomatology medical instruments field, is specifically related to root canal file active length dip stick in a kind of root canal.
Background technology
Root canal file is one of very important instrument in the department of stomatology root canal.When using root canal file, need select the root canal file of appropriate length usually according to patient's oral cavity parameter, namely need mainly directly to measure with vernier caliper or ruler at present by measuring the active length of root canal file length records root canal.Because read vernier caliper or the ruler scale is subjected to the influence of eyesight and light, and require the precision of surveying work length higher, auld doctor is difficult to see clearly the scale on the chi.
The utility model content
The technical problems to be solved in the utility model is: a kind of root canal file active length dip stick is provided, makes auld doctor can read scale fast when measuring the root canal file active length.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: a kind of root canal file active length dip stick, it is characterized in that: it comprises the dip stick body, the dip stick body is provided with display, shift knob and measuring flume, one end of measuring flume is provided with displacement transducer, and the middle part of measuring flume is provided with fixture block; Wherein the length overall of measuring flume is greater than the length of root canal file, and displacement transducer is to the active length of the distance between the fixture block greater than root canal file, and the width of measuring flume is greater than the handle width of root canal file; Also be provided with microprocessor in the dip stick body, the output terminal of displacement transducer is connected with the input end of microprocessor, and the output terminal of microprocessor is connected with display.
Press such scheme, described display is LCD.
Principle of work of the present utility model is: during measurement, root canal file is put into measuring flume, the limited block of root canal file is positioned at the fixture block right side just, and at this moment the distance between the file bar end of fixture block and root canal file just in time is the active length of root canal file.Because the distance between displacement transducer and the fixture block is known, as long as displacement transducer is measured the distance between displacement transducer and the file bar end, can calculate the active length of root canal file.Microprocessor shows the active length of calculating at display, the numeral that the doctor needs only direct reading displayed device can be known the active length of root canal file.
The beneficial effects of the utility model are: by adopting the utility model structure, make auld doctor can read scale fast when measuring the root canal file active length, made things convenient for operation.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the internal circuit configuration block diagram of the utility model one embodiment.
Fig. 3 is the structural representation of root canal file.
Among the figure: 1. dip stick body, 2. LCD, 3. button, 4. measuring flume, 5. fixture block, 6. displacement transducer, 7. file bar, 8. banking stop, 9. handle.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Fig. 1 is the structural representation of the utility model one embodiment, Fig. 2 is the internal circuit configuration block diagram of the utility model one embodiment, it comprises dip stick body 1, dip stick body 1 is provided with display (display is LCD 2 in the present embodiment), shift knob 3 and measuring flume 4, one end of measuring flume 4 is provided with displacement transducer 6, and the middle part of measuring flume 4 is provided with fixture block 5; Wherein the length overall of measuring flume 4 is greater than the length of root canal file, and displacement transducer 6 is to the active length of the distance between the fixture block 5 greater than root canal file, and the width of measuring flume 4 is greater than the handle width of root canal file; Also be provided with microprocessor in the dip stick body 1, the output terminal of displacement transducer is connected with the input end of microprocessor, and the output terminal of microprocessor is connected with display.
Fig. 3 is the structural representation of root canal file, and root canal file is formed by connecting by file bar 7 and handle 9, also is provided with banking stop 8 on the file bar, and the distance L between banking stop 8 and file bar 7 ends is the active length of root canal file.
During use, only root canal file need be put into measuring flume 4, make the limited block of root canal file be positioned at fixture block 5 right sides just; Open button 3, displacement transducer 6 measure displacement transducers 6 with file between bar 7 ends apart from a and pass to microprocessor MCU, microprocessor by displacement calculating sensor 6 to the distance b between the fixture block 5 deduct between displacement transducer 6 and file bar 7 ends apart from a, can obtain the active length L of root canal file; The result that display is calculated microprocessor shows, and the reading of the direct reading displayed device of doctor gets final product.
