Prosthetic Knee Joint- Polycentric Four Bar Knee Joint With Pneumatic Swing Phase Control For AK And KD


Polycentric Four Bar Pneumatic Knee Joint unit,K13AL, is the most stable with a large stance control angle(up to 32°) in the current prosthetic and orthotic market.K13AL also has various alignment adjusting abilities, referring to the following instructions, and its weight is less than 1 Kg. Furthermore, the independent adjusting flexion/extension ability makes gait patents close to normal ones.

Single-chamber pneumatics control the swing phase,In swing phase, the smooth yet powerful single-chamber pneumatics- one chamber each for flexion and extension damping do not run out of air, even at various walking speeds. Harmonious flexion and extension movements, and therefore an approximation of the physiological gait pattern, are made possible. Here the joint geometry effectively shortens the prosthesis during swing, resulting in more ground clearance. Four-axis polycentric structure ensures stance phase stability In extension, the instantaneous centre of rotation is located above the joint and behind the load line, resulting in high stability in stance phase. The integrated extension assist spring ensures that the lower leg of the prosthesis is always extended at heel strike and weight can be safely supported on the prosthesis side. This is especially advantageous when the user takes small compensating steps, turns in a circle or walks in confined areas.
Easy to fit

Flexion and extension dampening can be separately and individually customised to the needs of the user .A quick start guide included with the delivery facilitates the alignment process and helps establish the prosthesis settings. This effectively reduces the working time of the prosthetist and leads to rapid fitting success.
