摘要： A passive ankle-foot prosthesis to replicate a human foot. The passive ankle-foot prosthesis includes a foot part, an ankle frame, a yoke, and a spring. The ankle frame is attached fixedly to a second end of the foot part. The yoke is configured to be attached to a residual limb of a user. A first end of the yoke is pivotally attached to a first end of the ankle frame utilizing a pivot. The yoke is configured to rotate around a pivot axis. The pivot axis passes through the pivot. The spring is disposed between the ankle frame and the yoke. A first end of the spring is connected to a second end of the yoke. A second end of the spring is connected to a second end of the ankle frame. The spring is configured to apply an upward force to the second end of the ankle frame based on the yoke's rotational movements.
