Biomechanical Design & Stance Safety:

• • 5-Bar Polycentric Geometry: Advanced multi-link mechanism providing a dynamic stabilization feature that shifts the joint’s rotation center up toward the hip at heel strike, completely preventing unexpected buckling.

  • The Bouncing Mechanism: Features integrated shock-absorbing bumpers that allow for a slight elastic deflection (4° or less) at heel strike. This dampens ground impact and reduces vertical center-of-gravity shifting for an exceptionally smooth, energy-efficient “double knee action” gait.

Fluid Swing Phase Control:

• • Low-Resistance Hydraulic Cylinder: Specifically engineered to avoid the “heavy swing” feeling common to traditional hydraulic knees. It delivers a light, free-swinging feel similar to pneumatic models during pre-swing, but progressively scales up resistance during acceleration to match changing cadences up to 105 steps per minute.

Clinical Customization & Ergonomics:

• • Highly Adjustable Stance: The duration, volume, and sensitivity of the stance bounce can be precision-tuned via bumper compression to perfectly match the patient’s weight and habits.

  • Features an easily adjustable extension assist and flexion resistance to optimize terminal swing.

  • Sleek, Patient-Friendly Contours: Designed with an S-shaped front link that avoids socket interference when fully bent (up to 150°), an enclosed internal extension stop to eliminate clothing pinches, and a friendly, organic aesthetic.

  • Highly suitable for long residual limbs due to its low-profile knee center and minimal build height.
