英文摘要:

      To solve the mismatch between optical positioning equipment and existing medical ultrasound instrument in the application of injection surgery with the introduction of optical positioning technology in muscle spasm therapy, the work aims to further improve the stability of theoretical positioning accuracy, simplify the necessary operation, and reduce the difficulty of practical application. Based on the functions of the existing ultrasound instrument and related equipment and combined with the requirements of optical positioning equipment working conditions, the demand analysis was carried out and the functional flow model of product components was reconstructed and mapped to network nodes. At the same time, based on the importance evaluation method of complex network nodes, the design center of the target product was determined and designed in layers. Finally, the rationality of the test design was verified by simulation. The experimental results were in line with the expected hypothesis, and the correlation between the functional element corresponding to the target node and other nodes was correlated with the complexity of compatible connections required by the target element. On the basis of experiments, a design scheme that could adapt to optical locator and ultrasound equipment was obtained, which effectively solved the problems of nonintuitive and invisible intramuscular injection guided by two-dimensional ultrasound navigation. The importance evaluation method based on complex network nodes is more suitable for the design and research of complex functional products, and the importance difference of evaluation results is more significant.
