德國癌症研究中心 (DKFZ) 的創新研究人員團隊推出了一種名為 TrainBots 的新型迷你機器人,可協助改善醫療程序等。這些新單元可以完成諸如與其他機器人連接以及導航複雜的身體通道(例如腸道中的通道)等任務。以下是您需要了解的有關 TrainBot 的信息,以及它們如何幫助改善數百萬人的生活。
Mini Robots in Healthcare
醫療保健中的微型機器人
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.
微型機器人繼續在醫療保健領域找到一席之地。這些設備現已用於診斷、提供治療等。微型機器人的特徵是體積微小,大多數尺寸在奈米到公分之間。值得注意的是,這些設備為醫護人員帶來了許多好處。一方面,它們可以幫助進入難以到達的區域,並在許多新的非侵入性外科手術中發揮至關重要的作用。因此,整個市場對這些服務的需求強勁。然而,這些微型機器人在許多方面都受到限制。
Problems with Mini Robots Today
當今迷你機器人的問題
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.
醫療保健領域微型機器人的主要問題之一與它們在許多場景中表現出色的原因相同:它們的體積很小。這些機器人的微小性質意味著它們無法移動或攜帶任何需要大量力量的東西。例如,單一微型機器人不可能部署又長又細的導管或重置軟組織並打開結構。這兩項任務都需要更多的動力才能將儀器安裝到位,因為它們的直徑範圍為 2-13 毫米,長度超過半公尺。
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,人體內非常滑。器官被柔軟的生物組織覆蓋。當與所需的複雜導航相結合時,很容易理解為什麼與目前使用小型攝影機和手動專業人員引導治療到位的方法相比,更強大、更有能力的非侵入性替代方案是首選。
TrainBots Could Change this Scenario
TrainBots 可以改變這種情況
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.
根據最近的一項研究,TrainBot 的概念可能是答案,TrainBot 是一種能夠與其他設備連接的迷你機器人。這些專用微型機器人旨在以最小的努力精確地導航人體的距離。作為該策略的一部分,DKFZ 研究人員顯著提高了當前的奈米機器人標準。

TrainBots Get New Feet
TrainBots 邁出新步伐
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.
迷你機器人平台最大的升級之一是抓握力的改進。研究人員意識到,主要問題之一是缺乏抓握力,這可能導緻小型機器人打滑,從而導致最小運動所需的能量過多。為了改善這個問題,團隊添加了帶刺的附屬物。
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.
這些突出的節點有助於分佈身體附肢表面的接觸。此外,每隻腳的設計和角度都經過最佳化,以提高驅動力和致動力,使 TrainBot 能夠更有效率、更省力地移動。
Wireless Control for TrainBots
TrainBot 的無線控制
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.
研究的另一個重要面向是控制系統。這些微型機器人利用永磁裝置,使醫療保健專業人員能夠無線控制它們。具體來說,旋轉磁場使 TrainBot 能夠連接起來並一致地移動,顯著提高驅動力,並允許外科醫生控制速度和旋轉等重要方面。
Connected
已連接
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.
這些微型機器最酷的方面是它們能夠連結和連接以形成具有更多功率的更大機器人。這些設備可以協同工作,在需要時提供有價值的服務。例如,可以將多個單獨的機器人連接起來,以產生足夠的電力來運輸內視鏡器械。該車隊提供必要的驅動力,使醫療保健專業人員能夠利用它進行精確的外科手術。
Testing TrainBots
測試 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 概念的測試包括模擬外科手術。過程使用豬器官,其運作環境與人體相似。豬的器官出現了膽管堵塞的跡象,這是人類常見的疾病。
Using TrainBots to Reduce Risks of Bile Duct Cancer
使用 TrainBots 降低膽管癌的風險
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.
隨著時間的推移,受影響的個體會出現膽管阻塞,這可能導致膽汁積聚和包括癌症在內的嚴重疾病。目前治療這種常見疾病的方法是,醫療保健專業人員將攝影機插入您的口腔中,並手動引導其穿過小腸以確定阻塞部位。
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,研究人員能夠以最少的努力消除堵塞。該過程首先連接三個 TrainBot,以產生足夠的拉力,將 25 公分長的電極絲拖過豬的小腸。值得注意的是,該管子的重量是火車機器人的 3.5 倍。
TrainBots Results
TrainBots 結果
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.
火車機器人成功地將貨物運送到位。一旦金屬絲尖端正確定位在膽汁堆積物旁邊,研究人員就會施加少量電荷來打破阻塞並釋放腸道通路。這個過程稱為電灼,它只是 TrainBots 旨在改進的眾多程序之一。
