4 BAR POLYCENTRIC KNEE

4 BAR POLYCENTRIC KNEE

SECURE STRIDE G

A 4-bar polycentric mechanical knee with geometric lock designed for moderately active amputees.

PRODUCT FEATURES

Biomechanical & Stance Control:

    • Polycentric Mechanical Design: Multi-axis geometry that provides automatic functional toe clearance during the swing phase, significantly reducing the risk of trips and falls.

    • Geometric Locking System: Offers a high degree of structural safety and absolute stability while standing (stance phase).

    • Natural Release Mechanism: The stance lock disengages smoothly and naturally as slight pressure is applied to the toe during terminal stance.

Swing Phase Control:

    • Utilizes adjustable knee axis friction to control the overall speed and resistance of the swing.

    • Equipped with an integrated extension assist spring to help efficiently propel the lower leg forward into full extension before the next heel strike.

Key Product Advantages:

    • Greater Control & Stability: Increases patient confidence when walking and negotiating variable, uneven terrain, supporting a safer and more efficient gait.

    • Improved Safety: Maximizes ground clearance to actively prevent stumbles while allowing the patient to stand safely without fear of the knee buckling.

    • Cost-Effective Durability: Delivers trusted mechanical reliability with low maintenance requirements, maximizing the service life of the prosthesis.
