摘要： An apparatus is disclosed for a rolling contact joint that is particularly useful as a prosthetic joint such as a knee joint, as well as other applications requiring relatively movable sections having mechanical joints. The joint may take a variety of forms depending upon the particular situation, but in essence, includes at least two bodies that have surface portions in contact, with the bodies being movable relative to one another and constrained in this movement by the nature of the surfaces in contact and flexible straps positioned about and also in contact with the bodies. Where a basic configuration including a pair of cylinders is utilized, the flexible straps may be wrapped completely or partially around each of the cylinders to provide a joint having substantially no restraint of motion with very low friction due to the rolling contact between the contacting surfaces of the cylinders. In addition, such bodies may each have a pair of cylindrical surfaces of different diameter with respect to one another with the bodies in contact at one cylindrical surface and the flexible straps wrapped about the other of the cylindrical surfaces. If the cylindrical surfaces are concentric with respect to one another and have diameters of proper ratio, there will be no substantially resistance to the motion, and because of the rolling contact, friction will be very low. If the cylindrical surfaces are not concentric, however, then the flexible straps will be strained during rotation and a spring action will be provided in the device. Since the shape of the bodies and the positioning of the flexible straps determines the particular type of motion, various possible combinations have been described. In addition, a particular embodiment of a rolling contact joint is described for use as a prosthetic knee joint.

摘要： An apparatus is disclosed for the rolling contact joint that is particularly useful as a prosthetic joint such as a knee joint. The basic joint may take a variety of forms depending upon the particular situation, but in essence, includes at least two bodies that have surface portions in contact, with the bodies being movable relative to one another and constrained in this movement by the nature of the surfaces in contact and flexible straps positioned about and also in contact with the bodies. Since the shape of the bodies and the positioning of the flexible straps determines the particular type motion, various possible combinations have been described. A particular embodiment of a rolling contact joint is described for use as a prosthetic knee joint. When so utilized, the joint is implanted as a replacement for the natural knee joint, and includes a femoral section and a tibial section with the femoral section having a curved surface that engages and rolls upon a surface of the tibial section with the sections being constrained to rolling motion by a plurality of straps fastened to the sections and extending partially therearound.
