Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a spine electronic measuring instrument based on magnetic / inertial devices. Background technique [0002] The spine is very important to the human body. Once the spine deforms, it will cause many symptoms. The most common ones are pain in key positions such as the head, neck, and chest, and even incontinence, dizziness, and palpitation. In the most severe cases, paralysis can occur. [0003] Spinal deformation is the root cause of spinal diseases. Early measurement and early correction are crucial. The three measurement methods currently used: Cobb angle, Jackson physiological stress curve, and Harrison posterior tangent method are all based on spinal imaging. For example, X-ray, CT scan technology, patients with these measurement methods must go to relevant medical institutions, and they have certain radiation, the measurement cost is high, and due to work and daily...

[0003] Spinal deformation is the root cause of spinal diseases. Early measurement and early correction are crucial. The three measurement methods currently used: Cobb angle, Jackson physiological stress curve, and Harrison posterior tangent method are all based on spinal imaging. For example, X-ray, CT scanning technology, patients with these measurement methods must go to relevant medical institutions, and have certain radiation, the measurement cost is high, and due to work and daily life factors, it is inconvenient to measure

[0004] With the development of attitude measurement technology, electronic spine measuring instruments have appeared, such as Idiag SpinalMouse in Switzerland and SpineScanTM in Israel. The measurement principle is the same, based on the angle measurement relative to the ground level, that is, three-dimensional gravity sensing technology; because The measurement angle is calculated based on the gravity components on the three axes, which will definitely be affected by the accuracy of gravity extraction; since only one angle of the spine can be measured at a time, if you want to measure other angles, you must change to other measurement modes, resulting in The measurement operation is cumbersome; there is also a spine electronic measuring instrument that uses resistive strain gauges or strain gauges, and strain is used to measure stress changes. Generally, small changes are measured, and the spine may change at a large angle, so there may be some problems in the measurement principle. Some problems; In addition, since these electronic spine measuring instruments are composed of a host computer, an industrial computer, and a printer, they cannot be well portable
