Medical technology is constantly evolving, and now scientists have taken a major step forward by creating a medical robot that can directly treat diseases instead of just diagnosing them. These robots are opening up new possibilities in the field of internal medicine.
One exciting development is the origami robot designed by researchers at MIT. This tiny device is about the size of a capsule and features a red outer layer made from dried pig intestine, which makes it easier to swallow. If someone accidentally swallows something harmful, this robot can be used to retrieve it. Once it reaches the stomach, the outer shell expands, and doctors can use an external magnetic field to guide its movement. The robot then searches for the foreign object, captures it, and safely removes it from the body with the help of the same magnetic field.
Testing has shown that this robot can successfully remove coins, button batteries, and even repair minor damage to the stomach lining. It's a game-changer in emergency medical procedures, especially when dealing with swallowed objects that could cause serious harm.
Another breakthrough comes in the form of a pill-shaped robot designed for automatic drug delivery inside the body. Traditional injections, while necessary, can be painful and stressful, especially for patients who require long-term treatment like those with diabetes, multiple sclerosis, or rheumatoid arthritis. To address this issue, researchers have developed a device called Rani.
Rani looks like a regular capsule but works as an auto-injector that delivers medication directly into the intestinal wall. After being swallowed, the capsule protects the drug proteins from breaking down in the digestive system. When it reaches the small intestine, the outer shell dissolves, and a balloon inflates, triggering a biodegradable needle (made from materials like sugar) to inject the drug into the intestinal wall. The needle dissolves on its own, and the remaining components pass through the digestive system without causing blockages.
Experts believe the intestines are an ideal site for drug absorption, making this technology a promising alternative to traditional injections. It offers a more comfortable and convenient option for patients who need regular medication, reducing both physical discomfort and psychological stress. As these innovations continue to develop, they bring us closer to a future where medical treatments are less invasive, more precise, and far more patient-friendly.
