Esophageal atresia is a rare inherited disease. The upper and lower parts of the baby's esophagus are not connected - there is a gap between them. Scientists at the University of Sheffield and Children's Hospital of Boston have created a better way to treat this disease in the form of implantable robotic devices.
In general, esophageal atresia is treated with a surgical technique called fooker (Foker). It involves pulling the ends of the esophagus using sutures.
Dr. Dana Damian of the University of Sheffield, who led the study, said: “Doctors have been performing Foker surgery because they are aware that the organization can be stretched by pulling the tissue. However, they do not know how much force should be used to generate tissue elongation, despite This technique is one of the best standards, but sometimes the suture surgeon will attach to the esophagus, which may lead to repetitive surgery or the formation of scar tissue, which in the future will cause problems for the patient."
This is why scientists decided to develop this robotic device.
Next to the esophagus, connect the organ through two rings (see above). Use a motor and apply pressure gradually, gently pulling both ends of the esophagus towards each other. Sensors in the device carefully measure and adjust the tissue tension. This tension does not simply stretch the tissue, but actually promotes new cell growth.
The device is powered by an external control unit that is attached to a baby's vest. This means that babies can perform certain activities while receiving treatment. In contrast, infants undergoing Foker surgery must remain substantially immobile throughout the treatment so that they will not pull out the suture.
Damian said: "We have created a device that can use the onboard medical expertise to control tissue growth over a long period of time. We also want to look at other tubular tissues such as the gut and vascular system to see if this technology can be used to help Treat other diseases such as short bowel syndrome."
A paper on this research was recently published in the journal ScienceRobotics.
