◆ High Precision Machining:CNC (Computer Numerical Control) machining enables extremely high precision, typically controlled within ±0.01mm or better, resulting in finely crafted products with long lifespans.Traditional casting processes are influenced by various factors, leading to relatively low dimensional accuracy and short product lifespan. Cast parts tend to have relatively rough surfaces and may contain defects such as sand holes and air pores.
◆The knee joint features original U.S-imported INA sealed needle roller bearings, significantly extending its service life more than three times that of standard knee joints.
◆Front end design of gravity line in the stance phase in relation to knee joint rotary axle, providing stability in the stance phase.
◆Applicable to common walking in consistent gait; with knee extension assist control function in swing phase during walking; separate extension damping design and knee axle friction damping design to achieve independent control and natural gait.
◆Multi-axial knee joint with extended linkage, providing higher flexion sensitivity of the knee joint and easier walking.
◆Unique multi-axial extra-thin connection design for the knee joint flexion, applicable to patients of knee disarticulation and different residual limb sizes.
◆Flush shape compatible with various functional connectors and can be equipped with sockets of different materials.
◆High knee flexion angle 150°. More freedom of movement and wearing comfort for prosthesis wearers, e.g. when kneeling, sitting and donning.
