1.1 Construction and Function
The 3R106-Pro* Prosthetic Knee Joint is a polycentric prosthetic knee joint. It is available in the
following versions:
•
3R106-Pro (with proximal pyramid adapter; in combination with the 4R156* Tube Clamp
Adapter for hip disarticulation)
•
3R106-Pro=KD (with proximal lamination anchor for knee disarticulation)
•
3R106-Pro=ST (with proximal threaded adapter for long residual limb prostheses)
The prosthetic knee joint features a large flexion angle (175°) (see fig. 3). It is equipped with auto-
adaptive, pneumatic swing phase control for walking at different speeds. Flexion
and extension
damping can be adjusted separately and individually (see fig. 4).
The upper joint section
and lower joint section
are connected by the two anterior links
and the posterior link
to form a four-bar linkage. In extension, the instantaneous centre of rota
tion
is located above the joint and behind the weight bearing line, thus providing knee stability
in the stance phase (see fig. 2).
The distal portion of the pneumatic cylinder is fabricated as a tube clamp and accommodates the
provided tube adapter.
The integrated extension assist spring is part of the swing phase control mechanism and ensures
extension of the prosthetic knee joint. If required, it can be replaced by the included weaker
spring. Here it is important to ensure that the patient always achieves full extension while walking.
1.2 Combination possibilities
INFORMATION
When fabricating a prosthesis for the lower limbs, all of the prosthetic components used have to
meet the requirements in regard to the patient's body weight and activity level.
Prosthetic components that are especially well suited for combination with the product are listed
below.
