摘要： An hydraulic heel-height adjustment device for a lower limb prosthesis has a foot- mounting component for detachably mounting a prosthetic foot and a shin component pivotally connected to the foot-mounting component allowing angular adjustment of the foot-mounting component relative to the shin component about a heel-height adjustment axis. The relative angular position is set by an hydraulic piston and cylinder assembly which has a chamber in the shin component containing a piston arranged to execute a translational movement in the chamber when adjustment is required. A bypass passage interconnects parts of the chamber on opposite sides of the piston, this passage containing a manually operable valve which is spring-biased towards a closed position. The piston has a piston rod pivotally connected to the foot- mounting component by a pivot joint defining a medial-lateral axis parallel to and spaced from the heel-height adjustment axis. Sufficient clearance between the piston rod and bores in which it is mounted is allowed to permit some misalignment of the piston within the chamber. By providing a piston which executes translational movement inside a component associated with the shin, the device can be located proximally of a foot connection interface without occupying excessive space.

摘要： An artificial limb has an endoskeletal shin component (10A) which is of generally constant H-shaped cross section and is formed by injection moulding from thermoplastics material. In a preferred embodiment, the limb has a foot keel (10B) which is integrally moulded with the shin component (10A), the keel (10B) having a longitudinal web (20) which is coplanar with a central web (12) of the shin component (10A). The keel (10B) also has upper flanges (24, 26) which are contiguous with anterior and posterior flanges (14, 16) of the shin component (10A). Such a limb can be made light in weight yet strong in terms of resistance to transverse bending moments, and can be inexpensively produced. The constant cross section of the skin component allows it to be cut to a required length and clamped to an upper limb component (52, 60).

摘要： A prosthetic ankle and foot combination has an ankle joint mechanism constructed to allow damped rotational movement of a foot component relative to a shin component. The mechanism provides a continuous hydraulically damped range of ankle motion during walking with dynamically variable damping resistances, and with independent variation of damping resistances in the plantarflexion and dorsiflexion directions. An electronic control system coupled to the ankle joint mechanism includes at least one sensor for generating signals indicative of a kinetic or kinematic parameter of locomotion, the mechanism and the control system being arranged such that the damping resistances effective over the range of motion of the ankle are adapted automatically in response to such signals. Single and dual piston hydraulic damping arrangements are disclosed, including arrangements allowing independent heel-height adjustment.

摘要： A vacuum-assisted liner system for the socket of a limb prosthesis secures the prosthesis to a residual body portion. A vacuum is created directly between the residual body portion and the socket (8) to hold them together and minimise relative movement between them. The system includes a flexible liner (4) made of an impermeable material, at least a distal part (4D) of the liner being porous to allow the transport of air and fluid directly away from the residual body portion to the outer surface of the liner. A fabric distribution layer (6) is located over the liner (4) and between the liner and the socket (8) to allow transmission of such extracted air and fluid laterally over the liner to an evacuation port (10) in the socket. Also disclosed is a limb apparatus suspension device incorporating the liner system, and a vacuum suspension device which secures a component such as a stamp socket to a residual body portion by creating an evacuated space sealed by intimate contact directly between the socket (8) and a boundary region of the liner (4).
