德国癌症研究中心 (DKFZ) 的创新研究人员团队推出了一种名为 TrainBots 的新型迷你机器人,可以帮助改善医疗程序等。
A team of innovative researchers from the German Cancer Research Center (DKFZ) has introduced a new type of mini robot called TrainBots that could help improve medical procedures and more. These new units can accomplish tasks such as linking up with other bots and navigating complex bodily passages like those found in your intestine. Here's what you need to know about TrainBots and how they could help improve the lives of millions one day.
德国癌症研究中心 (DKFZ) 的创新研究人员团队推出了一种名为 TrainBots 的新型迷你机器人,可以帮助改善医疗程序等。这些新单元可以完成诸如与其他机器人连接以及导航复杂的身体通道(例如肠道中的通道)等任务。以下是您需要了解的有关 TrainBot 的信息,以及它们如何帮助改善数百万人的生活。
Mini Robots in Healthcare
医疗保健中的微型机器人
Mini robots continue to find a home in the healthcare sector. These devices have now been used to diagnose, deliver treatment, and more. Mini robots are characterized by their tiny nature with most measuring between a nanometer and a centimeter. Notably, these devices bring a lot to the table for healthcare workers. For one, they can help to access hard-to-reach areas and play a vital role in many new non-invasive surgical procedures. As such, there’s a strong demand for these services across the market. However, these tiny robots are limited in many ways.
微型机器人继续在医疗保健领域找到一席之地。这些设备现已用于诊断、提供治疗等。微型机器人的特点是体积微小,大多数尺寸在纳米到厘米之间。值得注意的是,这些设备为医护人员带来了很多好处。一方面,它们可以帮助进入难以到达的区域,并在许多新的非侵入性外科手术中发挥至关重要的作用。因此,整个市场对这些服务的需求强劲。然而,这些微型机器人在很多方面都受到限制。
Problems with Mini Robots Today
当今迷你机器人的问题
One of the main issues surrounding mini robots in healthcare is the same reason they are excellent in many scenarios: their tiny size. The sheer minuscule nature of these robotics means that they can't move or carry anything that requires a lot of force. For example, it would be impossible for a single mini robot to deploy a long and thin catheter or reset soft tissues and open up a structure. Both of these tasks require a lot more power to get the instruments in place as they can range in size from 2–13 mm in diameter and stretch over half a meter long.
医疗保健领域微型机器人的主要问题之一与它们在许多场景中表现出色的原因相同:它们的体积很小。这些机器人的微小性质意味着它们无法移动或携带任何需要很大力量的东西。例如,单个微型机器人不可能部署又长又细的导管或重置软组织并打开结构。这两项任务都需要更多的动力才能将仪器安装到位,因为它们的直径范围为 2-13 毫米,长度超过半米。
Additionally, it's very slippery inside the human body. Organs are covered in soft biological tissue. When coupled with the complex navigation required, it's easy to see why a stronger more capable noninvasive alternative is preferred versus the current method of using small cameras and a manual professional to guide the treatments into place.
此外,人体内非常滑。器官被柔软的生物组织覆盖。当与所需的复杂导航相结合时,很容易理解为什么与当前使用小型摄像机和手动专业人员引导治疗到位的方法相比,更强大、更有能力的非侵入性替代方案是首选。
TrainBots Could Change this Scenario
TrainBots 可以改变这种情况
The concept of a TrainBot, a mini robot with the capability to link with other devices could be the answer according to a recent study. These purpose-built micro-robotics were designed to navigate the distances of the human body precisely and with minimal effort. As part of this strategy, DKFZ researchers significantly improved the current nanorobotics standards.
根据最近的一项研究,TrainBot 的概念可能是答案,TrainBot 是一种能够与其他设备连接的迷你机器人。这些专用微型机器人旨在以最小的努力精确地导航人体的距离。作为该战略的一部分,DKFZ 研究人员显着提高了当前的纳米机器人标准。

TrainBots Get New Feet
TrainBots 迈出新步伐
One of the biggest upgrades to the mini robot platform is improved gripping. The researchers realized that one of the main issues is a lack of gripping force which can lead to small robotics slipping, resulting in excess energy requirements for minimal movement. To improve this issue, the team added spiked appendages.
迷你机器人平台最大的升级之一是抓握力的改进。研究人员意识到,主要问题之一是缺乏抓握力,这可能导致小型机器人打滑,从而导致最小运动所需的能量过多。为了改善这个问题,团队添加了带刺的附属物。
These protruding nodes help distribute contact across the surface of body appendages. Additionally, the design and angle of each foot were optimized to improve driving and actuating forces, enabling TrainBots to move more efficiently and with less effort.
这些突出的节点有助于分布身体附肢表面的接触。此外,每只脚的设计和角度都经过优化,以提高驱动力和致动力,使 TrainBot 能够更高效、更省力地移动。
Wireless Control for TrainBots
TrainBot 的无线控制
Another vital aspect of the research is the control system. The tiny robots leverage a permanent magnetic set-up which enables them to be wirelessly controlled by healthcare professionals. Specifically, a rotating magnetic field enables TrainBots to link up and move in unison, improving driving force significantly, and allowing surgeons to control vital aspects such as speed and rotation.
研究的另一个重要方面是控制系统。这些微型机器人利用永磁装置,使医疗保健专业人员能够无线控制它们。具体来说,旋转磁场使 TrainBot 能够连接起来并一致移动,显着提高驱动力,并允许外科医生控制速度和旋转等重要方面。
Connected
已连接
The coolest aspect of these tiny machines is their ability to link and connect to form a larger robot with more power. These devices can work together to provide valuable services when needed. For example, several individual robots can be linked to create enough power to transport an endoscopic instrument. The convoy provides the necessary actuating force to enable healthcare professionals to leverage it for precise surgical procedures.
这些微型机器最酷的方面是它们能够链接和连接以形成具有更多功率的更大机器人。这些设备可以协同工作,在需要时提供有价值的服务。例如,可以将多个单独的机器人连接起来,以产生足够的电力来运输内窥镜器械。该车队提供必要的驱动力,使医疗保健专业人员能够利用它进行精确的外科手术。
Testing TrainBots
测试 TrainBots
Testing for the TrainBot concept included a simulated surgical procedure. The process used pig organs, which operate in an environment similar to the human body. The pig organ showed signs of bile duct blockage which is a common disease in humans.
TrainBot 概念的测试包括模拟外科手术。该过程使用猪器官,其运行环境与人体相似。猪的器官出现了胆管堵塞的迹象,这是人类的常见疾病。
Using TrainBots to Reduce Risks of Bile Duct Cancer
使用 TrainBots 降低胆管癌的风险
Bile duct obstructions occur over time in affected individuals which can lead to bile buildup and serious diseases including cancer. The current method of treating this common ailment is for healthcare professionals to insert a camera in your mouth and navigate it manually through the small intestine to determine the blockage site.
随着时间的推移,受影响的个体会出现胆管阻塞,这可能导致胆汁积聚和包括癌症在内的严重疾病。目前治疗这种常见疾病的方法是,医疗保健专业人员将摄像头插入您的口腔中,并手动引导其穿过小肠以确定堵塞部位。
Using TrainBots, researchers were able to remove the blockage with minimal effort. The process began by connecting three TrainBots to generate enough pulling power to drag a 25 cm long wire electrode through the pig's small intestine. Notably, the tube was 3.5x the weight of the Trainbots.
使用 TrainBots,研究人员能够以最小的努力消除堵塞。该过程首先连接三个 TrainBot,以产生足够的拉力,将 25 厘米长的电极丝拖过猪的小肠。值得注意的是,该管子的重量是火车机器人的 3.5 倍。
TrainBots Results
TrainBots 结果
The trainBots successfully delivered their cargo in place. Once the tip of the wire was properly located next to the bile buildup, the researchers applied a small electrical charge to break down the blockage and free the intestinal pathway. This process is called electrocauterization and it's just one of many procedures that TrainBots are designed to improve.
火车机器人成功地将货物运送到位。一旦金属丝尖端正确定位在胆汁堆积物旁边,研究人员就会施加少量电荷来打破堵塞并释放肠道通路。这个过程称为电灼,它只是 TrainBots 旨在改进的众多程序之一。
