Introduction:

Four-bar structure of mechanical joints ensures  good security of joint

 

By adjusting the resistance adjustment of mechanism, which can effectively control speed of joint flexion and extension,so that users can get a good gait.

 

The joint has an optional connector which can be used for above knee  and knee disarticulation prostheses.

 

The connectors, such as pyramid, can be adjusted on the front and back of the sagittal plane . So users can get the best comprehensive security performance and flexibility, feel more comfortable to use.

 

The joint body is made from aluminum alloy structure with the character of small size, light weight. The comprehensive performance is significantly different from the conventional stainless steel four-bar joints.
