Abstract
Puncture needles have attracted wide attention in clinical applications due to their micro-invasive property and controllability. However, the complex human anatomy is calling for higher flexibility and safety. In this study, puncture needles with different sidewall grooves inspired by the structure of mosquitos' labrum were designed. It was proved that the sidewall groove could magnify the deformation of needles caused by the beveled tip. The sidewall groove also moved the high-stress area from the tip to the bottom, which made the needle damage more noticeable. This bio-inspired structure can enhance the flexibility of puncture needles and improve the sensitivity of needle damage detection.
期刊介绍:
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
