摘要： The invention in some embodiments relates to a dynamic seal for a prosthetic knee. The dynamic seal in one embodiment is utilized to seal a magnetorheological fluid comprising a liquid and solid particles within a chamber of the knee. The dynamic seal embodiments are specially configured with a pre-loaded tensioned garter spring which has a coil spacing that is at least as large as the size of the particles or maximum size of the particles in the magnetorheological fluid. Desirably, this allows the magnetorheological fluid particles to flow in and out of the dynamic seal without clogging the seal and advantageously provides for a reliable dynamic seal.

摘要： The invention in some embodiments relates to systems and methods of loading fluid in a prosthetic knee. A vacuum fill technique is utilized in one embodiment to load magnetorheological fluid within small gaps in a chamber of a prosthetic knee. Advantageously, this allows for an efficient loading scheme thereby desirably allowing for faster manufacturing speed. Another advantage is that the magnetorheological fluid is substantially uniformly distributed within the small gaps thereby desirably providing consistent production.

摘要： A prosthetic knee provides a single axis of rotation and includes a hydraulic damping cylinder, a microprocessor, and sensors. Based on input from the sensors, the microprocessor selects a flow path within the hydraulic cylinder in order to provide the proper amount of knee resistance to bending for a given situation. The resistance of each flow path within the hydraulic cylinder is manually preset. Changes in gait speed are accommodated by employing a hydraulic damper with intelligently designed position sensitive damping. Moreover, the knee need not be un-weighted to transition from the stance phase to the swing phase of gait. As a result, the knee safely provides a natural, energy efficient gait over a range of terrains and gait speeds and is simpler, less costly, and lighter weight than the prior art.
摘要翻译：假肢膝盖提供单个旋转轴线，并包括液压阻尼缸，微处理器和传感器。基于来自传感器的输入，微处理器选择液压缸内的流路，以便在给定情况下为弯曲提供适当的膝盖阻力。手动预设液压缸内的每个流路的阻力。通过采用具有智能设计的位置敏感阻尼的液压阻尼器来适应步态速度的变化。此外，膝盖不需要不重视从步态的摆动阶段向摆动阶段过渡。因此，膝盖在一定范围的地形和步态上安全地提供了一种天然的，节能的步态，并且比现有技术更简单，成本更低，重量更轻。
