Technical field
The utility model is related to field of measuring technique, and in particular to a kind of human cervical spine rotation angle measurement ruler.
Background technology
Measurement is the phenomenon that describing to observe, i.e., to make quantificational description to things with data according to certain rule.It measures
For ruler as common tool, it is evaluation growth and development and the sick and wounded patient of cervical vertebra to have a wide range of applications human cervical spine rotation angle measurement
The important parameter of Cervical Rotating function.Such as atlas axis fracture treatment after cervical vertebra rotation function evaluation, at present accurately
Measurement method is to be measured by the CT scan of the left-handed position of cervical vertebra and dextrorotation position, but the inspection needs hospital high-resolution thin
Layer CT, measurement is got up, and not only cumbersome, cost is larger, but also also has ray radiation to testee.
Chinese invention patent《Ruler》(publication number：103770530A；Publication date：On May 7th, 2014) in provide one kind
There is ruler body 1, ruler body side to be carved with graduation mark, protractor 11, protractor are provided in the middle part of the other side of ruler body for ruler, the ruler
It is labeled with scale, ruler body 1 is hollow along 11 graduation mark position of protractor.The structure of the ruler is as shown in Figure 1.In use, using angulation
Device 11 measures angle, makes a mark and can draw in the hollow part corresponding position of ruler body 1.But the ruler is only capable of in plane
Upper measurement or graphing.It cannot be used for the measurement of human cervical spine rotation angle.
It follows that existing measuring scale cannot be used for human cervical spine rotation angle measurement.In addition, existing measuring scale without
Method is used for medical measurement.
Utility model content
Problem makes improvements the utility model in view of the prior art, i.e., technical problem to be solved in the utility model is
A kind of human cervical spine wheel measuring ruler is provided, the human body Cervical Rotating measuring scale is simple in structure, easily operated to can be used for appraiser
Body Cervical Rotating function.To solve the above problems, technical solution provided by the utility model is：
A kind of human cervical spine rotation angle measurement ruler, including axis pin, the first ruler, the second ruler and round protractor, institute
It states the first ruler and is provided along its length the first strip through-hole, the first ruler is close to human body head side, second ruler
It is provided along its length the second strip through-hole, the second ruler human body is equipped with center close to head forehead, the circle protractor
Through-hole, the protractor are used to measure angle between the first ruler and the second ruler, and the axis pin sequentially passes through the from top to bottom
One strip through-hole, the second strip through-hole, central through hole, the axis pin can be slided along the first strip through-hole and the second strip through-hole, institute
Stating the first ruler and the second ruler can rotate around axis pin.
Further, first ruler and the second ruler are equipped with scale.
Further, the surface of the axis pin is equipped with screw thread, and both ends are connected with nut, the nut by the protractor,
First ruler and the locking of the second ruler.
Human cervical spine wheel measuring ruler described in above-mentioned technical proposal includes the first ruler connected by axis pin, second straight
Ruler and round protractor.Since axis pin can be slided along the first strip through-hole and the second strip through-hole so that the second ruler can edge
The length direction of first ruler slides, and can also be slided along the length direction of itself.First ruler and the second ruler can
It is rotated around axis pin.That is relative rotary motion occurs between the first ruler and the second ruler.It is surveyed respectively by round protractor
Go out to rotate the angle between preceding first ruler and the second ruler, the angle after rotation between the first ruler and the second ruler, to
Calculate the angle that the second ruler is rotated relative to the first ruler.It, can be by the first ruler when measuring the angle of human body head rotation
As benchmark, the second ruler is connect with human body head, human body head rotation drives the rotation of the second ruler, the angle of rotation to pass through
Round protractor is measured.Further, the side of the second ruler be equipped with can be along the locating clip of the Slideslip.Locating clip can be used for being aligned
Glabella point on human body head between two geisomas.Further, protractor, the first ruler and the second ruler can be locked by nut
Tightly.Convenient under different measuring phases, being read.
The utility model has the advantage that：
1. the utility model can carry out simple human cervical spine rotation angle measurement, easy to operate.
2. the utility model is simple in structure, easily fabricated.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of axis pin described in the utility model.
Specific implementation mode
With reference to embodiment and attached drawing, the utility model is described further.
Specific embodiment of the present utility model, as shown in Figure 1 to Figure 2.
A kind of human cervical spine wheel measuring ruler, including connected by axis pin 4 and be all provided with graduated first ruler 1, second
Ruler 2 and round protractor 3.Here the first ruler 1, the second ruler 2 and protractor 3 are set gradually from top to bottom.
First ruler 1 is provided along its length the first strip through-hole.First strip through-hole is passed through for axis pin 4.
