Abstract: An anti-shock artificial knee joint includes a pivot stop block forming a first pivot hole rotatably receiving therein a first pivot for bending the knee joint and a second pivot hole rotatably receiving a second pivot. A gap extending from the first pivot hole so that when the pivot stop block is subjected to an external force induced in the process of walking, the gap is reduced to secure the first pivot from rotation whereby the pivot stop block rotates about the second pivot to cause the pivot stop block to engage spring-biased pistons to thereby absorb the external force or the impact caused by the external force. The spring-biased pistons are provided with set screws to adjust the cushioning effect provided by the spring-biased pistons.

Abstract: A four-bar-linkage brake-included knee joint includes a knee carriage, first and second links rotatably coupled to the carriage, and a clamp member coupled to a joint body. The clamp member forms a through hole that receives an axle to couple the second links. A compression block is received in a rear portion of the joint body and is set in engagement with a back side of the clamp member. The clamp member forms a gap extending from the through hole of the clamp member to a bottom of the clamp member. When a heel of a prosthesis that includes the knee joint is put on the ground, a reaction force is induced in the prosthesis that causes the compression block to directly depress the clamp member thereby reducing the gap to have the clamp member tightly clamping the axle and thus preventing the axle from further rotation.

Abstract: A four-link hydraulic buffer knee joint assembly which includes a hydraulic center axle configured at a center hole of a four-link hydraulic main body and utilizes a spring force and an oil-filling piston to achieve the auto-filling of hydraulic oil. The hydraulic center axle is able to utilize adjustable knobs provided on an outer side of the center axle to adjust the bending speed and the spring-back recovery speed. The setting location of the hydraulic center axle differs from the one of conventional joint assembly such that the overall size of the knee joint assembly is reduced while the joint assembly includes the functions of adjustable hydraulic bending and stretching speeds and buffering for the hydraulic head to return to its horizontal state. The four-link hydraulic main body comprises a setting changeable controlling axle for achieving the function of the buffered safety brake against the ground.
