Scientists Build Tiny Gut Explorer Robot to Detect and Potentially Treat Lethal Common Cancer
Scientists have built a tiny gut explorer robot to detect and potentially treat a lethal common cancer, in the latest advance in the fast-evolving field of medical robotics.
How it works
The machine makes 3D scans of the colon that were previously impossible, using its mussel shell-like shape to roll through the digestive system when guided by a magnet outside the body. The innovation could boost detection of bowel cancer, which is treatable in its early stages but is the second-biggest cause of cancer deaths worldwide.
Potential Impact
"This minimally invasive robotic approach could significantly improve early diagnosis and, in future, allow targeted ultrasound-triggered medicine delivery," said Nikita Greenidge of Leeds university, lead author of a paper on the research published in Science Robotics on Wednesday.
Next Steps
Developers at Leeds, Glasgow and Edinburgh universities hope to launch human trials of the coin-sized robot next year, after successful testing on pigs.
Design and Functionality
The machine is 3D-printed from resin in a shape known as the oloid, which allows a wide range of movement and contact with surfaces. This means it can navigate and image the large intestine to an extent that was previously unattainable, the researchers said.
Advantages
The robot could enable virtual cancer screening that would eliminate delays, costs, and complications associated with traditional biopsy methods based on extracting bodily tissue, the authors write. Screening, diagnosis, and therapy could be carried out "in a single procedure" rather than the existing multi-stage processes lasting weeks or more.
Targeted Approach
The new method could be particularly helpful for women, the researchers say. Female colons are on average longer than their male equivalents, meaning standard screenings involving the insertion of a tube can be harder to carry out and more painful.
Industry Reaction
The project is an example of how cutting-edge technology is enabling the development of "rapid, non-invasive solutions that have the potential to revolutionise cancer diagnosis and treatment," said Jane Nicholson, executive director of research at the UK’s Engineering and Physical Sciences Research Council, which part-funded the work.
Conclusion
The tiny gut explorer robot has the potential to significantly improve early diagnosis and treatment of bowel cancer, a lethal common cancer that is the second-biggest cause of cancer deaths worldwide. If successful in human trials, this innovative technology could revolutionize cancer care, enabling virtual cancer screening and targeted treatment.
