Transfemoral prosthesis for walking, sitting- standing, stair climbing

A prosthesis or orthosis device comprising:

• a knee joint connectable with a leg of a user;
• a swing storage spring-gear mechanism comprising a balancing spring inserted in an ankle member housing located in an ankle member, a drive gear, a driven gear, an intermediate gear and a gear rod, and a foot part comprising a dorsiflexion spring, wherein the balancing spring is configured to prevent a foot from returning to 0 degrees with respect to a ground and striking the ground once again after a push-off;
• a lower leg connecting the knee joint and the foot part to each other, wherein a weight-receiving member is located in the lower leg,
• wherein the lower leg is connected to the knee joint, and the lower leg is connected to the foot part through the ankle member housing;
• a swing storage mechanism connected to the foot part by a second housing of a connection tube and a gear rod pin, and to the knee joint by a first housing of the connection tube and a first housing of the knee joint,
• wherein the swing storage mechanism comprises a swing adaptation mechanism consisted of nested connection member tubes and a connection member swing storage spring located in the nested connection member tubes, a spring cover, a guide screw and a brushless direct current (BLDC) motor,
• wherein the swing adaptation mechanism stores energy generated at different walking speeds,
• wherein a dorsiflexion spring tube containing the dorsiflexion spring is connected to the front of the foot part through a toe tip housings, and a piston rod pressing the dorsiflexion spring tube is connected to the ankle member at a back of a foot of the lea of the user,
• wherein the swing storage mechanism is configured to move in the foot part between at least two positions by the swing storage spring-gear mechanism;
• and
• a weight-receiving mechanism comprising the weight-receiving member and a compression arm and a lock fork for activating and deactivating the weight-receiving member,
• wherein the compression arm is connected to the knee joint through a compression spring housing, a knee joint third housing and a shaft, and to the weight-receiving member through a weight-receiving housing,
• wherein a lower end of the support arm is connected to the lower leg through lower leg housings and an upper end of the support arm is connected to the lock fork through a lock fork housing.
