Nabtesco INTELLIGENT KNEE NI-C411

Function of 4bar linkage mechanism
■Stability at the stance phase and smooth
　　 change to the swing phase
　・By newly employed extension support function,
　　complete extension at the time of the heel
　　contact is realized.
　・High stability makes walking on slopes and going
　　up and down stairs much easier.
　・Adequate toe clearance is secured. It reduces toe
　　 trippings.
■Natural walking posture
　・Natural movement close to that of a knee of
　　a normal leg is realized.
■Natural external appearance
　・Because of its compact size, natural external
　　appearance is realized at the time of sitting even
　　for amputees with long stump range or knee
　　disarticulation.
■160°Knee flexion
　・Maximum 160 degrees knee flexion allows various
　　postures during daily life.

Four bar linkage mechanism with an extension support function is
incorporated into the microcomputer controlled intelligent knee joint!
More natural walking and stability are realized..

Functions of Microcomputer-based Control
■Responding to the Speed Change Each Step
A sensor detects the walking speed each step;
the microcomputer controls the below-knee swing
corresponding to the current speed.
■Optimum Adjustment
The intelligent prosthesis knee joint offers you walking
freely at any speed dueto individual adjustment
■Battery Life Is Approximately Two Year
The microcomputer runs on battery.
The battery life is rated at two year.
■A Weak or Dead Battery Will Not Disturb Your Walking
If the battery runs down while you are walking , the swing
speed will not follow the walking speed but you will be
able to walk at an ordinary speed.
Once you change the battery, you will be able to walk at the desired speed..
