RÉSUMÉ
Cervical spondylosis is due to degenerative cervical disc and its stimulation or oppression of the adjacent nerves, spinal cord, spinal artery and other tissue caused by clinical symptoms. The cervical spine is an anatomical structure with activity, while the pillow has a certain plastic fixation effect on the cervical spine anatomy. Therefore, the pillow not only plays a health role in the cervical spine, but also plays an important role in restoring the normal physiological curvature of the cervical spine. Based on this, a multi-functional cervical vertebra treatment pillow is designed, which not only has the functions of traction, maintaining different positions of the cervical spine, correcting the cervical curvature and equipment exercises, but also has the functions of voice broadcast and network data terminal.
RÉSUMÉ
In the research of artificial joint biomechanics, it is a common method in the world to evaluate the biomechanical properties of the implanted fixtures through experiments . The domestic research started late, and the corresponding testing software were lacking. There is still no special software. In this paper, an integrated software test system was designed and built based on the existing hardware system, including:hardware control, data collection, data save, data processing and display. It can directly show the 3D motion trajectory and the angle curve of joints. The system can accurately measure the relative motion angle value, external torque value, and inter pressure value of each joint. It has some reference significance for the development of the artificial joints' evaluation system.
RÉSUMÉ
In the research of artificial joint biomechanics, it is a common method in the world to evaluate the biomechanical properties of the implanted fixtures through experiments . The domestic research started late, and the corresponding testing methods were lacking. There is still no unified standard. In this paper, a complete hardware test system was designed and built around the existing mechanical testing machine, including:binocular vision catcher, torque bearing clamp, film pressure sensor and so on. The system can accurately measure the relative motion angle value, external torque value, and inter pressure value of each joint. It has some reference significance for the forming and standardization of the artificial joints' evaluation system.
