According to technique scheme, compared with prior art, modular construction of the present utility model is simple, and design science is reasonable.This utility model is measured with two protractors, measures accurately, and operational approach is simple, and is easy to use.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
Fig. 2 is the newel perspective view.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments this utility model is further described.
This utility model is by pedestal 1, compositions such as newel 2 and protractor 3.Referring to accompanying drawing 1, pedestal 1 is that internal diameter is the irony drum of 5cm, and it is the catch 7 of the restriction newel anglec of rotation of one with it that the high 1.5cm of bucket, the upper limb of drum are provided with two, catch 7 high 1.5cm, and wide 1.0cm and pedestal 1 are one.The outer rim of two catch 7 is spaced apart 1/4 of drum diameter, and promptly two outer rims become an angle of 90 degrees with circle center line connecting.Mid point with 7 of two catch is a starting point, every interval pedestal 1 week the footpath 1/4 amount to 4 in the feather edge punching, as the fixed point that is fixing band 6.Article two, fixing band 6 is selected the elastic cord of long 35cm for use, and adjacent two holes with pedestal 1 edge, the rear end of every elastic cord are fixed.The front end of fixing band 6 is connected with thread gluing 8.Referring to Fig. 1, Fig. 2, newel 2 are that external diameter is 4.9cm, the round log post of high 4cm, and bottom 11 is complete circle cylinders of high 1cm, top 10 is semi-cylindrical in configuration of high 3cm.The wide 5cm in the base of two protractors 3, centre porose 9.Center ring 4 is 90 degree sector structures, and the both sides of center ring 4 are passed from the centre bore 9 of two protractors respectively, are fixed on the below of protractor 3 then, and are simultaneously that two protractors 3 are fixedly connected.Two protractors 3 are fastened on the end face and sagittal plane of newel 2 as measurement component with glue or pin, the bottom line that wherein is positioned at the protractor 3 of end face aligns with the sagittal plane of newel 2 semicolumns, the bottom line that is positioned at sagittal protractor 3 is parallel with newel 2 end faces, and pointer 5 is connected with center ring 4 between two protractors 3.The bottom full circle cylinder that the newel 2 of protractor 3 is installed partly is fixed in the pedestal 1.In order to limit the anglec of rotation of newel 2, two catch 7 are folded to the inboard of pedestal 1.
Operation principle of the present utility model and using method embodiment:
This measuring instrument is fixed on the intersection point place of both sides, patient crown external auditory meatus line and the bridge of the nose and occipital tuberosity line.When the measurement cervical vertebra bends and stretches, sagittal plane protractor 3 is identical with the bridge of the nose and occipital tuberosity line, along with cervical vertebra anteflexion or after stretch, sagittal plane protractor 3 rotates at sagittal plane with head, and pointer 5 remains vertically because of gravity, can read anteflexion on the protractor and after the angle of stretching.When measuring cervical vertebra left and right sides lateroflexion, the sagittal plane protractor revolved turn 90 degrees into coronalplane and both sides auditory meatus line and coincide, along with cervical vertebra left and right sides lateroflexion, the coronalplane protractor rotates at coronalplane with head, and pointer 5 remains vertically, can read the angle of left and right sides lateroflexion on protractor.When measuring the cervical vertebra anglec of rotation, make the measured get dorsal position, keep cervical vertebra in neutral position, pointer 5 forwards end face by sagittal plane to through center ring 4, adjust end face protractor 3 baselines and coincide in both sides external auditory meatus line, the left rotation and right rotation head and neck can be read the left rotation and right rotation reading on end face protractor 3.
When patient's head and neck is in when position deformity, can at first measure the number of degrees of deformity position, the number of degrees after the measurement activity then, the difference of the two is range of activity.
Measure embodiment:
The measured sits up straight and is directly leaning against on the chair, and the shoulder back of the body and pelvis are adjacent to or are fixed on the chair back, and spinal fixation prevents breast lumbar vertebra participation activity.Incidence is taken from right neutral position, then measuring instrument is fixed in the intersection point place of both sides, the crown external auditory meatus line and the bridge of the nose and occipital tuberosity line, adjust the position of measuring instrument: make sagittal plane protractor and the bridge of the nose and occipital tuberosity line identical, the sagittal plane protractor is revolved turn 90 degrees into coronalplane and both sides external auditory meatus line is identical.Begin after the adjustment to measure.When the measurement cervical vertebra bends and stretches, the sagittal plane protractor and the bridge of the nose and occipital tuberosity line coincide, along with cervical vertebra anteflexion or after stretch, the sagittal plane protractor rotates at sagittal plane with head, and pointer remains vertically because of gravity, can read anteflexion on the protractor and after the angle of stretching.When measuring cervical vertebra left and right sides lateroflexion, the sagittal plane protractor revolved turn 90 degrees into coronalplane and both sides external auditory meatus line and coincide, along with cervical vertebra left and right sides lateroflexion, the coronalplane protractor rotates at coronalplane with head, and pointer remains vertically, can read the angle of left and right sides lateroflexion on protractor.When measuring the cervical vertebra anglec of rotation, make the measured get dorsal position, keep cervical vertebra in neutral position, pointer forwards end face by sagittal plane to through center ring, adjust end face protractor baseline and both sides external auditory meatus line and coincide, the left rotation and right rotation head and neck can be read the rotation reading on the end face protractor.
