Special protractor for measuring degree of deviation of mandibular angle of torticollis of child from midline of human body

Abstract

The invention relates to a special protractor for measuring the degree of deviation of the mandibular angle of the torticollis of a child from the midline of a human body. The protractor comprises a container and an angle ruler arranged on the container, and the angle ruler comprises a median ruler and a rotary ruler; a horizontal line is arranged on the side wall of the container, a straight line where the projection of the median ruler on the side wall is located penetrates through the middle point of the horizontal line and is perpendicular to the horizontal line, and the container is used for containing liquid used for judging whether the horizontal line is in a horizontal state or not. The projection of the rotating center of the rotary ruler on the side wall coincides with the midpoint of the horizontal line, and the included angle between the rotary ruler and the median ruler is the degree of the angle ruler. By adopting the technical scheme, an accurate mandibular angle deviation median position degree value can be provided for rehabilitation evaluation, and accurate data comparison is provided in the rehabilitation process.

Description

technical field [0001] The invention relates to the technical field of medical measurement of the degree of deviation of the mandibular angle of children with torticollis from the midline, in particular to a special goniometer and a measuring method for measuring the degree of deviation of the mandibular angle of children with torticollis from the midline of the human body. Background technique [0002] Due to the gradual increase in the incidence of pediatric torticollis and the improvement of parents' medical knowledge in China, more and more children with torticollis seek medical examination and evaluation, but the evaluation tool for measuring the angle of mandibular deviation to the healthy side in children with torticollis is still blank Most of the status depends on the subjective experience of doctors or therapists to judge whether it is offset, and the amount of offset cannot be objective and accurate. Therefore, it needs to be improved. Contents of the invention ...

[0002] Due to the gradual increase in the incidence of pediatric torticollis and the improvement of parents' medical knowledge in China, more and more children with torticollis seek medical examination and evaluation, but the evaluation tool for measuring the angle of mandibular deviation to the healthy side in children with torticollis is still blank Most of them rely on the subjective experience of doctors or therapists to judge whether there is deviation. The value of deviation cannot be objective and accurate. Therefore, it needs to be improved.
