摘要:
A lower limb prosthesis (10) comprises a foot component (12) and an ankle unit (16) pivotally mounted to the foot component (12). The ankle unit (16) comprises an ankle joint mechanism (18) comprising a hydraulic piston and cylinder assembly for providing hydraulic damping whenever the ankle joint flexes, and a vacuum mechanism (20) comprising a pneumatic piston and cylinder assembly for generating a vacuum. The hydraulic and pneumatic piston and cylinder assemblies are arranged such that the vacuum mechanism generates a vacuum during plantar-flexion of the ankle unit (16).
