摘要： A polycentric knee joint including an adjustment-free multi-stage prosthesis air cylinder. The air cylinder has an air cylinder body, a piston assembly slidably mounted on the air cylinder body, a first check valve mounted in the piston, and a multi-stage air pressure valve mounted inside a lower air way of the air cylinder body. The multi-stage air pressure valve automatically cushions movements of the piston assembly without being adjusted whenever a user of the prosthesis joint walks slowly or quickly, for improved comfort.

摘要： An adjustable below-the-knee prosthetic leg, which is connected between a thigh and an artificial foot, comprises a controller, a connecting mechanism, a hydraulic unit, and a shell. The connecting mechanism and the hydraulic unit are pivotally connected to the controller, and the shell is pivotally connected to the hydraulic unit. The connecting mechanism extends into a hydraulic cylinder of the hydraulic unit. The hydraulic cylinder is in communication with a reserve hydraulic cylinder and a brake hydraulic cylinder of the hydraulic unit. The prosthetic leg allows a user to climb up or go down the stairs and walk on uneven ground easily without falling down.

摘要： An adjustment-free cushioning air cylinder includes an air cylinder body, a piston, a first check valve, an upper air way, a second check valve and a lower air way. An air chamber is formed inside the air cylinder body. The piston slides in the air chamber. One end of the piston extends to the external of the air cylinder body. The piston does a reciprocating movement in the air chamber and divides the air chamber into an upper air chamber and a lower air chamber. The first check valve is disposed in the piston, one end of the first check valve is connected to the upper air chamber, and the other end is connected to the lower air chamber. The upper air way connects the upper air chamber with the outside. The adjustment-free cushioning air cylinder of the invention does not need to adjust the entering flow rate of the air, but the entering flow rate can be automatically adjusted to produce cushioning resistance as the user is walking according to the walking speed. The present invention has a simple structure, high cushioning performance, lower cost, and is not easy to damage, thus can greatly improve the product competitiveness.

摘要： A prosthetic knee joint with buffering and braking effects has an upper connecting base, a linking assembly, a braking assembly, and a lower connecting base. The upper connecting base has two extending lugs and an accommodating recess. The linking assembly has two linking arms respectively and pivotally connected to the upper connecting base. The braking assembly has a braking arm protruding into the accommodating recess of the upper connecting base and pivotally connected to the two extending lugs. The lower connecting base is connected to the linking assembly and the braking assembly. The upper connecting base, the linking assembly, the braking assembly and the lower connecting base form a four-bar linkage. A cushion between an abutter and a main body provides a buffering effect during walking. Thus, the prosthetic knee joint has simplified structure and reduced cost and is convenient in assembly and use.
