1. Wearing Comfort
Elastic skin-friendly knitted outer layer with flexible medical silicone inner core boosts air permeability and sweat drainage, avoiding sweaty and irritated residual limb skin during long-time wear.
High-damping silicone cushions walking impact, reduces pain and pressure on the stump end for below-knee amputees during standing and daily walking.
2. Stable Fixation Performance
Fixed size 320 for precise matching with designated prosthetic sockets, closely wrapping residual limb without slipping or shifting while moving.
Built-in female metal thread fits locking prosthetic mechanism, enabling fast donning/doffing and reliable locking stability.
3. Long Service Life
Outer textile layer prevents scratch and abrasion to extend silicone service life compared with full-smooth silicone sleeves.
Medical-grade anti-aging silicone resists erosion from human sweat, keeps stable flexibility all seasons, no hardening, stickiness or oil leakage under high/low temperature. -

Standing Anti-Fall with Self-Locking Mechanism
A four-axis联动 system creates a geometric locking mechanism that automatically locks the knee joint when standing under load, enabling stable standing even for users with weaker lower limb strength, elderly individuals, or those newly fitted with prosthetics. Walking on flat ground or gentle slopes is smooth and less prone to leg buckling or falls.
Step Forward Safely with Natural Gait
When stepping forward, the joint automatically shortens the effective length of the prosthesis and raises the toe clearance from the ground, significantly reducing the risk of dragging feet or tripping. It mimics natural human walking patterns, resulting in a more coordinated and aesthetically pleasing gait.
Large Knee Flexion Range for Unrestricted Daily Activities
With maximum flexion reaching 145°–170°, it allows effortless squatting, sitting on low stools, kneeling, and climbing stairs—ideal for everyday scenarios such as home use, shopping, and short-distance travel.
II. Pneumatic Damping System: Effortless Walking at Various Speeds
Independently Adjustable Flexion and Extension Resistance
The cylinder features separate channels for flexion and extension, allowing fine-tuning of resistance based on user weight and walking speed. Whether strolling slowly or walking briskly, movement remains smooth and seamless without jerking during speed changes.
Built-in Assist Spring Reduces Physical Strain
A high-stiffness assist spring supports active knee extension, ensuring smooth rebound during the swing phase. This reduces fatigue during prolonged walking and offers greater ease compared to mechanical locking knees.
Pneumatic Medium for Hassle-Free Operation
Unlike hydraulic knees, there's no risk of oil leakage. The system maintains stable airtightness and consistent damping performance across temperature extremes, making it suitable for both cold northern climates and humid southern regions.
III. Materials and Craftsmanship: Lightweight, Durable, and Long-Lasting
Aerospace-Grade Aluminum Alloy Forged in One Piece
The main body is CNC-machined from precision aluminum alloy, with an anodized colored shell (blue in the image). The lightweight design ensures significantly lower overall weight than heavy steel joints, minimizing wearer burden. The metal casing resists impacts and corrosion.
Roller Needle Bearings for Smooth Transmission
Precision roller needle bearings are used in the connecting rod pivot points, ensuring smooth rotation with minimal friction loss. This results in reduced wear over repeated use, low repair rates, and extended service life.
High Load-Bearing Capacity
The standard model supports up to 125 kg, meeting the daily load requirements of most adult amputees.
IV. Installation, Adjustment, and Maintenance Advantages
Easy Alignment Adjustment
The top conical core allows slight front-to-back translation, enabling prosthetists to quickly achieve precise alignment. This broadens adaptability to various residual limb conditions.
Simple and Low-Cost Maintenance
The pneumatic structure eliminates frequent hydraulic oil replacement; only periodic checks of valve seals are required. With standardized components, repairs and replacements are cost-effective, ideal for long-term home use.
Wide Compatibility
Suitable for transfemoral and knee disarticulation amputees, this prosthesis is ideal for individuals with moderate activity levels. It meets both rehabilitation training needs and daily long-term mobility, offering excellent value for hospitals and rehabilitation centers requiring bulk fittings. -
