Researchers in the United Kingdom have developed an autonomous, snakelike robot that could slither down human lungs into places that are difficult to reach, potentially improving the detection and treatment of lung cancer or other pulmonary diseases.
allowing doctors the ability to better scan a patient’s lungs for cancerous tissue. They are designed to ease a task doctors have long struggled with: reaching the inner recesses of the human body, for diagnostic and treatment purposes, without causing damage or using invasive procedures.
“If you are not able to get a tissue sample, then you have to evaluate the risk of … not doing anything,” he said. “This is a reason why, very often, cancer is detected at a very late stage.” Magnets mounted on robotic arms outside the patient would be used to help guide the device into the lungs. Once inserted into a patient, the magnets would help the robot move down a patient’s lungs autonomously, following a map of the patient’s lung network, which would be mapped out before the procedure.
Despite that, Thakor said any autonomous robot would face an uphill climb being accepted by clinicians. “Which surgeon is going to want to lose business,” he said. “People who do the clinical practice … guard it very carefully until they get trained.”into use. Valdastri’s team recently wrapped up trials of the robot in cadavers, which he said were successful. After that, they plan to test it in small animals.
