1.1 Construction and Function

The 3R60 Vacuum (3R60=VC) is a polycentric prosthetic knee joint with EBS (ergonomically bal­
anced stride) unit and an integrated, mechanical vacuum pump.
The EBS unit permits controlled stance phase flexion up to 15° while simultaneously improving
knee stability. This is accomplished by shifting the virtual pivot point (ICR – instantaneous centre
of rotation) in the proximal and posterior directions. Stance phase flexion takes place against the
resistance of an elastomer spring. Stance phase extension is dampened by hydraulics.
Flexion and extension during the swing phase is controlled by two continuously variable hydraulic
valves.
An integrated extension assist supports the swing phase.
The vacuum pump in the prosthetic knee joint is part of a vacuum system that improves the con­
nection between the prosthesis and residual limb. An ischial containment prosthetic socket and
other components are needed as well.

1.2 Combination Possibilities

For combination possibilities, please see the catalogue 646K2* or consult the manufacturer.
INFORMATION
Ottobock recommends using the product only in combination with socket systems that distribute
the vacuum over the largest possible area. The seal of the prosthetic socket should begin as
close underneath the socket entry section as possible. This ensures optimum control of residual
limb volume fluctuations.
Ottobock recommends the following socket system:
► ProSeal Ring (452A1=*) with a textile-free liner (e.g. 6Y81 Skeo Liner) and the 2R119 Vacu­
um Connection
