Abstract
A prosthetic ankle joint consists of a base which includes an upper base portion and a lower base portion. The lower base portion is formed with a substantially hollow receiving cavity extending inwardly from an end thereof remote from the upper base portion. A base member is movably positioned within the receiving cavity and is connected to a prosthetic foot. The base member is movable in side-to-side direction independently of the base, so as to enable the prosthetic foot to closely follow a walking surface. The motion of the base member is controlled by resilient biasing members positioned between the inner cavity and the base member.
Claims20
A prosthetic ankle joint for connection between a pylon and a prosthetic foot, the prosthetic ankle joint comprising:
- a bracket member adapted for connection to a pylon;
- a base consisting of an upper base portion and a lower base portion, said lower base portion is formed with a substantially hollow receiving inner cavity extending inwardly from an end thereof remote from the upper base portion;
- a base member movably positioned within the receiving inner cavity and connected to a prosthetic foot, said base member including a linear upright portion and a transverse portion, said transverse portion being transverse to the upright portion and connected to one end thereof, at least one resilient biasing member completely positioned within the receiving inner cavity adjacent said base member, said bracket member and said base being controllably movable in the anterior to posterior direction;
- and
- said base member and said prosthetic foot being controllably movable in the side to side direction independently of said base to enable said prosthetic foot to closely follow a walking surface.
A prosthetic ankle joint for connection between a pylon and a prosthetic foot, the prosthetic ankle joint comprising:
- a bracket member adapted for connection to a pylon;
- a base consisting of an upper base portion and a lower base portion, said lower base portion is formed with a substantially hollow receiving inner cavity extending inwardly from an end thereof remote from the upper base portion, a base member movably positioned within the receiving inner cavity, the base member is connected to a prosthetic foot;
- said base member having an inverse T-shaped configuration and comprises an upright portion extending outwardly from the lower portion so as to form first and second engaging zones on either side of the base member;
- a pair of resilient biasing members is provided within the receiving inner cavity to face the respective first and second engaging zones and to limit and control the arcuate motion of the base member.
