Background technology
In recent years, along with growth in the living standard, people improve constantly the attention degree of oral health, and the demand of oral cavity diagnosis and Education in Stomatology is also more and more higher.In the routine examination/therapeutic process of oral cavity, maximum opening degree, lower jaw lateral movement amplitude, cover/cover size, in 1/3 vertical dimension, Tooth Size, root canal, the measurement of the position length of tip of a root file etc. all be unable to do without dip stick under face.But in oral teaching and oral cavity diagnosis, dip stick used mostly is ruler, ruler at present.In the internal measurement of oral cavity, measuring point difference, measurement space size are totally different, and the length of ruler, ruler and profile are single, cannot meet variation, the accurate needs measured.
Utility model content
The purpose of this utility model is to provide a kind of multifunctional oral cavity check measurement chi, and it can carry out opening degree measurement, two-way mandibular movement is measured, covered/cover measurement, the Orifice locating linear measure longimetry of breach shape and common examination of mouth and measures.
For achieving the above object, this utility model is achieved by the following technical solutions.
A kind of multifunctional oral cavity check measurement chi, is characterized in that, comprise main scale plate, described main scale plate indicates the short right-angle side of distance scale, a long right-angle side that indicates distance scale and a curved side that indicates angle index by one and surrounds; Described long right-angle side and short right-angle side intersect vertically, and one end of long right-angle side is being provided with short right-angle side intersection the cantilever chi bar extending along with long right-angle side, and the distance scale on the direct limit of described length extends on cantilever chi bar; Described cantilever chi bar and short right-angle side joint are provided with positioning clamp; Described curved side two ends are crossing with long right-angle side and short right-angle side respectively, and curved side profile is one section of Ah rice Jede helical, curved side the radius of curvature of one end crossing with long right-angle side be less than curved side with the radius of curvature of the crossing one end of short right-angle side.
Feature of the present utility model and further improvement are:
The angle of the intersection of described long right-angle side and described curved side is 110～130 °, and described intersection is provided with the sector notch that a diameter is 1～2mm.
Described positioning clamp vertically stretch out main scale plate and with short right-angle side keeping parallelism.
Described main scale plate is provided with taking positioning clamp as starting point, the measurement zone subsidiary scale mark parallel with long right-angle side.
The beneficial effects of the utility model are, using the short right-angle side of main scale plate, long right-angle side, curved side respectively as lower jaw lateral movement displacement Special measuring scale, common ruler, oral cavity opening degree dip stick, cantilever chi bar, positioning clamp is special with in the measurement of covering after dental articulation/level of coverage and root canal length respectively, make it there is opening degree measurement, the measurement of two-way mandibular movement simultaneously, cover/cover the five functions that measurement, the Orifice locating linear measure longimetry of breach shape and common examination of mouth are measured.

In above figure: 1, main scale plate; 2, short right-angle side; 3, long right-angle side; 4, cantilever chi bar; 5, positioning clamp; 6, curved side; 7, sector notch.
Detailed description of the invention
With reference to figure 1, a kind of multifunctional oral cavity check measurement chi of the present utility model, it comprises main scale plate (1), main scale plate (1) by one indicate the short right-angle side (2) of distance scale, long right-angle side (3) and the curved side (6) that indicates angle index that indicates distance scale surrounds.
Wherein, long right-angle side (3) intersects vertically with short right-angle side (2), one end of long right-angle side (3) is being provided with short right-angle side (2) intersection the cantilever chi bar (4) extending along with long right-angle side (3), and the distance scale on long direct limit (3) extends on cantilever chi bar (4).Cantilever chi bar (4) is provided with positioning clamp (5) with short right-angle side (2) joint.Curved side (6) two ends are crossing with long right-angle side (3) and short right-angle side (2) respectively, curved side (6) profile is one section of Ah rice Jede helical, curved side (6) the radius of curvature of one end crossing with long right-angle side (3) be less than curved side (6) with the radius of curvature of the crossing one end of short right-angle side (2).
Short direct limit (2), in order to measure people's lower jaw lateral movement displacement, is provided with middle groove labelling in its distance scale.Long right-angle side (3) uses as the ruler of common survey.Cantilever chi bar (4) is main in order to measure covering after dental articulation/level of coverage.Curved side (6) is in order to measure people's oral cavity opening degree.On positioning clamp (5), can place root canal file location leather packing, measure root canal length.
