摘要： An ankle module for a prosthetic foot can have an adapter portion pivotally coupled to a base portion. The base portion can be coupled to the prosthetic foot. The adapter portion can have a coupling member that removably couples the prosthetic foot to a prosthetic pylon or socket. The adapter portion can also have cylinders housing pistons slidably displaceable within the cylinders. An actuator is selectively actuatable to place the cylinders in fluid communication, allowing a fluid to flow between the cylinders as an angular position of the adapter portion is adjusted relative to the base portion, thereby adjusting the dorsi-plantar position between the adapter portion and the base portion of the ankle module. The actuator can be selectively actuatable to fluidly isolate the cylinders from each other so that the angular position of the adapter portion relative to the base portion remains substantially fixed.

摘要： Linear actuators that allow for improved self-locking properties without sacrificing axial response are provided. A linear actuator can have two screws extending from opposite ends of the actuator. The screws are joined by and threadably coupled to an elongate rotating nut. An elongate magnet is disposed around and coupled to the nut, and a stator including coils surrounds the magnet and nut. The magnet and nut are not axially fixed with respect to the stator. Rotation of the nut causes axial displacement of both screws, causing the screws to move closer together or farther apart. A pitch of the screw threads can be selected to enhance self-locking properties.
