Ottobock announces the 3R60=VC Vacuum Knee Joint for transfemoral amputees. The joint is based on the mechanical principle of the 3R60 EBS (ergonomically balanced stride), with the new feature being the vacuum pump integrated in the upper joint section of the 3R60 Vacuum. The pump functions via an intake valve connected to the socket by flexible tubing. When the knee joint is flexed, the pump generates negative pressure in the socket while the outlet valve vents air and sweat. The fully integrated pump simplifies fitting with no increase in structural height or weight, and offers a cosmetic advantage.
