Scientists have created a robot that can stitch vessels with a diameter of up to 0.3 mm. The first tests of a device for supermicrosurgery in humans were successful, according to scientists from the Eindhoven University of Technology

According to hightech.fm,, super microsurgery is a relatively new method that focuses on connecting very small vessels during surgery: their diameter is from 0.3 to 0.8 mm. Most often, this method is used to combat lymphedema, a disease that usually occurs after treatment for breast cancer and leads to edema and localized fluid retention.

Given the complexity of the connection of such vessels, at the moment only a small number of surgeons are able to carry out supermicrosurgical operations.

To increase the number of patients who can receive surgical care for lymphedema, the researchers created the MUSA robotic system.

During the test operation, the device copied the movements of the leading surgeon on a reduced scale. The algorithm built into the system at the same time analyzed and memorized the movements of the hands and automatically filtered out tremors and random movements. The doctor controlled what was happening, focusing on a picture from a microscope.

After 3.5 months after the operation, the doctors evaluated the condition of the vessels of the patients and came to the conclusion that the operation was successful. In the near future, developers will continue testing the device.
