KLS Martin SonicWeld Rx A German surgical medical device specialized in ultrasonic welding of facial and jaw bones. Used in maxillofacial surgery and pediatric orthopedic surgery instead of metal plates and screws. Idea: Instead of fixing the fracture with a titanium screw, use absorbable pins or plates made of biomaterials. The device generates ultrasonic waves that melt the pin head and weld it to the bone within 5 seconds. After 6 months to a year, the body completely absorbs them. No second surgery is needed to remove them.
