Hydraulic Prosthetic Knee Joint - Waterproof Self-Locking Single-Axis

This single-axis hydraulic knee joint uses a single-axis swing hydraulic cylinder as its “joint heart”, Equipped with Swing and Support Control (SNS) technology, it creates a safe and natural walking experience for users through intelligent damping adjustment and practical design. Its core advantages are as follows:

1.Core control: Two-stage damping, adaptive gait full scene
Swing phase: It can provide variable hydraulic damping for knee flexion and extension according to changes in the patient’s walking speed; Built-in “gait following function” (no extra adjustment needed), When the user walks faster, the joint automatically increases the knee flexion damping to help the joint return quickly, keeping the gait natural and smooth.
Support phase: Provides locking damping sufficient to support the entire body weight, The load-bearing damping can be set via the adjustment ring— by adjusting the resistance of the hydraulic or mechanical damping system, the flexion speed of the knee joint when bearing weight is controlled, This greatly improves stability and smoothness when walking, going downhill and descending stairs, effectively preventing “leg buckling” and falls.

2.Gait optimization: Gentle and natural, adapting to multiple speeds
Through knee swing control adjustment, it precisely matches the damping for knee flexion and extension, Even when the user’s walking speed changes, it can maintain a gentle gait, Avoids stiff movements and improves walking comfort.

3.Basic performance: Balances load-bearing and protection
Load weight：The weight limit is 120kg, which can meet the needs of most users.
Water-resistant design: It is water-resistant and can be used in freshwater environments, meeting the needs of various daily scenarios such as swimming and bathing.

Competitive Advantage
1.Two-stage damping, adaptive gait full scene
