Abstract
An alignment adapter for prosthetic sport feet, such as running feet, includes a male pyramid plate having a male pyramid, a female connector plate having a female connector, and a back plate. For use during alignment of a prosthetic running foot, the male pyramid plate is coupled to the back of a user's socket and the female connector plate and back plate are clamped about the foot. The male pyramid and female connector are coupled and adjusted relative to one another to achieve a desired alignment. The socket and foot are locked in an alignment fixture to maintain the alignment and the male pyramid, female connector, and back plates are removed. A laminated plate is coupled to the socket to maintain alignment during normal use.
Claims20
A temporary alignment adapter for use with prosthetic sport feet, comprising:
- a male pyramid plate having a male pyramid and configured to be temporarily coupled to a socket sized to receive a user's amputated leg;
- a female connector plate having a female connector and configured to be placed adjacent a front of a prosthetic foot proximate a proximal end of the prosthetic foot;
- a back plate configured to be placed adjacent a back of the prosthetic foot proximate a proximal end of the prosthetic foot;
- and
- one or more fasteners configured to couple the female connector plate and back plate, wherein the fasteners are configured to extend alongside rather than through the prosthetic foot so that the female connector plate and back plate are clamped about the prosthetic foot;
- wherein the male pyramid is configured to engage the female connector and relative movement between the male pyramid and female connector adjusts alignment of the prosthetic foot relative to the socket.
An alignment system for use with prosthetic feet, the system comprising:
- a male pyramid plate having a male pyramid and configured to be temporarily coupled to a back of a socket sized to receive a user's amputated leg;
- a female connector plate having a female connector and configured to be placed adjacent a front of a prosthetic foot proximate a proximal end of the prosthetic foot, the female connector removably coupleable to the male pyramid and selectively fixed relative to the male pyramid to define a desired alignment between the prosthetic foot and the socket;
- a back plate configured to be placed adjacent a back of the prosthetic foot proximate a proximal end of the prosthetic foot and removably coupled to the female connector plate about the prosthetic foot;
- and
- a laminated plate configured to be coupled to the back of the socket to maintain the desired alignment during normal use and following removal of the male pyramid plate from the socket.
A method of aligning a prosthetic foot, comprising:
- attaching a male pyramid plate having a male pyramid to a back of a socket sized to receive a user's amputated leg;
- placing a female connector plate having a female connector with set screws adjacent a front of a prosthetic foot proximate a proximal end of the prosthetic foot;
- placing a back plate adjacent a back of the prosthetic foot proximate the proximal end of the prosthetic foot;
- coupling the female connector plate and back plate via fasteners extending alongside the prosthetic foot such that female connector plate and back plate are clamped about the prosthetic foot;
- coupling the socket and the prosthetic foot to an alignment fixture;
- engaging the male pyramid and female connector and adjusting the male pyramid and female connector relative to each other to obtain a desired alignment between the prosthetic foot and the socket;
- setting the desired alignment by tightening the set screws of the female connector about the male pyramid;
- and
- clamping the prosthetic foot to the alignment fixture to maintain the desired alignment.
