An international research team of biomechanical engineers and surgeons has developed a revolutionary micro 3D printer that can repair damaged tissue during vocal cord surgery. The printer head is only 2.7 millimeters in size, the smallest bioprinter ever developed, and can apply hydrogels to the surgical area with extreme precision.
After vocal cord surgery, many patients develop stiff vocal cords, making it difficult to speak. This is often caused by fibrosis (scarring) in the healing tissue. Hydrogels can counteract this process and support the healing process, but until now, administering these substances by injection has not been sufficiently accurate.
The new robotic printer, developed at McGill University in Canada, offers a solution. “Our device is designed not only for precision...
