摘要： An artificial knee joint includes a joint seat, a support frame, a hydraulic device, a push rod, and a biasing member. The joint seat has a joint body and a rotatable member connected pivotally to the joint body and connected fixedly to a residual thigh. The support frame is connected rotatably to the joint body, and is connected fixedly to a prosthetic lower leg. The push rod is movable relative to the joint body between an extended position, where a free end of the rotatable member is spaced apart from the joint body to align the lower leg with the thigh, and a retracted position, where the free end of the rotatable member abuts against the joint body. The biasing member biases the push rod to the extended position.

摘要： A mechanical joint for a leg brace having portions attachable to the leg above and below the knee joint and interconnected by a link. The spaced ends of the brace portions and the opposite ends of the link are shaped to provide bearing plates which are secured together by movable pivot means. This provides the mechanical joint with dual bearings having a combined pivotal movement closely simulating the flexing action of an anatomical knee.

The points XP(φ), YP(φ) of one guiding element (3) and the points XQ(φ) and YQ(φ) of the other guiding element (4) correspond approximately to the following equations: XP(φ)=A1×φ5+b1×φ4+C1×φ3+D1×φ2+E1×φ−F1; YP(φ)=A2×φ5+B2×φ4+C2×φ3+D2×φ2+E2×φ−F2; XQ(φ)=A3×φ5+B3×φ4+C3×φ3+D3×φ2+E3×φ−F3; YQ(φ)=A4×φ5+B4×φ4+C4×φ3+D4×φ2+E4×φ−F3, the deflection angle f of the knee joint being indicated in radians. The inventive knee joint prosthesis enables a significant adaptation to the natural movement.

摘要： The patent describes a leg prosthesis for adaptation to the stump of the upper leg, which is comprised of an adapter for a knee joint, a knee joint attached to it and a prosthetic lower leg coupled to the knee joint with a prosthetic foot coupled to it. It can be swiveled into the heel position, wherein the knee joint is designed so that when it moves from the extended position into the bent position, it makes a combined rolling/sliding movement on a swivel axis, in such a way that the distance from a point in front of the swivel axis when seen dorsally to the end of the prosthetic lower leg steadily decreases and from a point in front of the swivel axis seen ventrally to the end of the prosthetic lower leg steadily increases.

摘要： An artificial joint for simulating motion of a natural slide and hinge joint of the body, such as those at the knee, elbow or ankle. The disclosed joint comprises rigid overlapping plates connected by a pivot and slide arrangement. First and second pivot bearing elements engage first and second arcuate bearing surfaces on the respective plates to interconnect the plates for controlled sliding and pivoting action relative to one another. One bearing surface has a configuration approximating the convex extremity of one member in the simulated joint. The remaining bearing surface controls the spacing of the two pivot axes to introduce proper forward or rearward displacement thereof in simulating joint movement. The joint may be utilized as a lateral brace for a natural joint, or may be utilized as a lateral brace for a natural joint, or may be modified to serve as an articulating joint in an artificial limb.
