用自己的血造機器人沙腦瘤。
Use your own blood to build a robotic sand brain tumor.

中國團隊真的做到了。
The Chinese team really did it.
這個直徑只有一毫米，比針頭還要細的微型機器人，不用開顱，不用微創，就能精準的鑽進大腦深處殺腫瘤。
This is one millimeter in diameter.
Tiny robots that are thinner than a needle.
No minimally invasive.
You can precisely drill into the sand tumor deep in the brain.
任務完成之後呢，還能自動降解，連二次手術都省了。
After the task is completed.
It degrades automatically.
You can’t even do a second surgery.
就在今年的5月份，中科院的徐天天教授，深圳大學的王奔博士，聯合港中大的張立教授，在頂級期刊《自然-生物醫學工程》發表了這項震撼研究。
So this was back in May.
Tiantian Xu, Chinese Academy of Sciences.
Dr. Ben Wang from Shenzhen University.
Professor Zhang Li of United University of Hong Kong.
In the top journal Nature Biomedical Engineering.
Published this shocking study.
你敢相信嗎？醫生只需要抽一管血，15分鐘就能定制一個專屬機器人。
Can you believe it?
The doctor only needs to draw a tube of blood.
You can customize a dedicated robot in 15 minutes.
它能像線蟲一樣，在大腦毫米級的縫隙裡面自由穿行，完全不會劃傷周圍的組織。
It can act like a nematode.
They’re moving through millimeter-sized gaps in the brain.
It doesn’t scratch the surrounding tissue at all.
在可編程磁場的控制下，機器人能自由擺動，爬行和滾動。
Under the control of a programmable magnetic field.
It’s free to swing, crawl and roll.
通過X射線呢，實時追踪，精準的爬到腫瘤的位置，定點爆破，釋放藥物。
What about real-time tracking with x-rays?
Precisely crawl to the position of the tumor.
fixed point blasting.
Release the drug.
更絕的是，因為機器人用的是病人自己的血液，身體呢完全不排斥，副作用降低了76%，藥效呢提升了3.2倍。
And here’s the thing.
Because the robot uses the patient’s own blood.
The body doesn’t reject it at all.
76 percent reduction in side effects.
The efficacy of the drug has increased by 3.2 times.
目前呢，已經在18頭小豬身上驗證成功。
So far, it has been successfully verified on 18 piglets.
以前呢，腦深部腫瘤，要么開顱，手術風險巨大，要么全身化療，副作用嚴重。
In the past, deep brain tumors.
Either craniotomy is very risky.
Or systemic chemotherapy.
Serious side effects.
稍有不慎還會影響語言、記憶、運動功能。
A little carelessness can also affect the motor function of language memory.
現在這個血液機器人能夠順著腦脊液這個天然通道，繞過血腦屏障，把藥物直接送到病灶，給腫瘤來了一個精準打擊。
Now this blood robot.
It can follow the natural channel of cerebrospinal fluid.
Bypassing the blood-brain barrier.
Deliver the drug directly to the lesion.
A precise blow to the tumor.
這次的技術突破，讓那些原本需要開顱的重症患者終於見到了希望的曙光。
This technological breakthrough.
For patients who otherwise would have needed a craniotomy.
Finally, a glimmer of hope.
在未來呢，很多的重症的腦部疾病，或許都能用上這種定制化的醫療機器人。
What about in the future?
Many serious brain diseases.
They could all use a custom medical robot.
這就是中國科技的硬實力，把醫療難題變成醫療奇跡，化不可能為可能。
This is the hard power of Chinese technology.
Transforming medical problems into medical miracles.
Make the impossible possible.
這才是真正的科技自立。
That’s true technological self-reliance.
為咱們中國的科技工作者點贊。
Praise for our Chinese science and technology workers.
