Prosthetic Geometric Lock Pneumatic Knee Joint For Disarticulation
The Model No. (K15AL) Prosthetic Geometric Lock Pneumatic Knee Joint is a mechanical knee component designed for transfemoral (above-knee) prosthetic systems. This advanced knee joint integrates a polycentric geometric locking mechanism with a pneumatic swing control system to provide stability during stance phase and smooth motion during swing phase.
This design significantly improves user safety, gait stability, and walking efficiency, enabling amputees to achieve a more natural walking pattern. The knee joint is specifically engineered for moderate-activity prosthetic users (K1-K2 mobility levels) in daily walking and rehabilitation applications.
Key Components and Functionality
Geometric Lock Mechanism
The knee utilizes a polycentric linkage system (four-bar or five-bar mechanism) that creates a geometric locking effect when the prosthesis is loaded. During the stance phase, the linkage structure stabilizes the knee and prevents unintended flexion, enhancing safety and balance.
Pneumatic Control System
The internal pneumatic cylinder provides air-based resistance to control knee flexion and extension during the swing phase. This system regulates the swing speed and enables smoother, more natural leg movement.
Polycentric Linkage System
The multi-axis linkage design simulates the biomechanics of the human knee joint. It shortens the effective limb length during swing phase, improving toe clearance and reducing the risk of tripping.
Stance Phase Operation
When the prosthetic foot contacts the ground and bears weight, the geometric linkage system automatically creates a locking effect, stabilizing the knee joint and preventing accidental buckling.
Swing Phase Operation
When the prosthetic leg leaves the ground, the locking effect is released. The pneumatic control system regulates the knee's flexion and extension speed to provide smooth and controlled swing motion.
