    摘要: A rotation damper for toggle joints prosthesis (1) that is arranged for swing phase control of the prosthesis, and incorporates a housing having at least one clamber (13) with a damping medium disposed therein is disclosed. The chamber is arranged so that the damping medium is displaced through a restriction (14a) with a swing motion of at least one pivot axle (6) in the prosthesis. The damping medium is a visco-elastic compound, having an ability to exert a bigger resistance at rapid motion processes as compared to slower processes.

    摘要: An artificial knee-joint provided with linkage mechanisms, where a thigh part and a lower-leg part are mutually connected by tow base linkage arms, each of which is pivotally connected at respective ends with both the lower-leg part and the thigh part, wherein the pivotal attachment points of the lower-leg part are disposed in moveable attachment elements which mutually coact in a manner such that the knee-joint will automatically either adopt a substantially locked or a moveable position, depending on the direction of the load acting on the knee-joint. The first attachment element is pivotally connected to the two base linkage arms extending from the thigh part and has three pivot points, whereas the second attachment element has two pivot points. The back base linkage arm extending from the thigh part is pivotally connected to both attachment elements. The second attachment element is provided with a lock-stop device which limits movement of the attachment element. When walking, the movement of the attachment elements function to automatically lock the knee-joint and to terminate a walking step in a natural fashion.

    摘要: A knee prosthesis comprising two pivotally interconnected members (10, 11) carrying a locking device (17) and a first end a second axle (20, 21). The first axle (20) forms a bearing axle for the locking device and the second axle (21) cooperates with the locking device for activation thereof. The second axle (21) is located at a distance behind the first axle (20) and is arranged to act upon the locking device in such a way that when the line of action (26) from a load on the knee prosthesis passes through the second axle (21) or between the first (20) and the second axle, said second axle will act upon the locking device to activate it, while when said line of action (26) passes through the first axle or in front of it the second axle (21) will be unloaded and the locking device (17) inactivated.

    摘要: A device for damping of the turning movement of a joint such as an artificial knee joint is built into a bearing bridge of a joint. The joint can be a seven pivot point joint with a shaft of one of the pivot points being provided with a gear-wheel. The damping device includes a hydraulic cylinder with a piston connected to the gear-wheel. Channels with chokes and back valves connect the two sides of the piston of the hydraulic cylinder whereby adjustable damping in several steps can be achieved. A compact design for a joint and damping cylinder is achieved.

    摘要: A fastening device for a prosthesis, the fastening device having a cylindrical channel and an inclined washer designed to accept insertion of a cylindrical inset, such as a tube, bar or peg, with minimal resistance and yet substantially prevent withdrawal of the cylindrical insert from the fastening device unless a release mechanism is operated to permit withdrawal. The device permits rotation of the cylindrical inset with respect to the fastening device while still securely fastening the cylindrical insert within the fastening device, so as to prevent unlocking of the device and separation of the cylindrical insert.
