这款毫米级机器人解决了微创手术中器械难以到达狭小区域的问题，做医疗机器人研发或微创手术的团队值得关注，未来可能改变活检和靶向给药的方式。
南洋理工大学研究人员开发出一款毫米级磁控软体机器人，宽仅4.4毫米，可在弱磁场驱动下在组织内爬行或滚动。其可编程磁芯能在一秒内切换工具，实现切割组织、抓取样本、给药、加热肿瘤等五种功能。在明胶和鸡肝测试中，超过99%的细胞存活。目前仍处于实验室阶段，但未来有望用于活检、靶向给药和肿瘤局部热疗等微创手术，尤其适合传统器械难以触及的体内区域。

A tiny robot is gaining the skills to perform surgeries inside the body. Researchers at Nanyang Technological University built a millimeter-scale magnetic soft robot that can perform five different internal functions. Measuring 4.4 mm at its widest, the robot is steered wirelessly by weak magnetic fields, crawling or rolling through tissue before switching tools in under a second. A reprogrammable magnetic core lets it cut tissue, grip and store samples, dispense drugs, and heat tumors. In tests on gelatin and chicken liver, over 99% of exposed cells survived. Still confined to the lab, researchers say it could one day perform minimally invasive procedures, such as biopsies, targeted drug delivery, and localized heating of tumors, in confined regions of the body that are difficult to reach with normal surgical instruments.
