ACTUATED LEG PROSTHESIS FOR ABOVE-KNEE AMPUTEES

摘要

The actuated leg prosthesis (10) comprises a knee member (12), a socket connector (22) provided over the knee member (12), an elongated trans-tibial member (14) having a bottom end (14C) under which is connected an artificial foot (20), and a linear actuator (16). A first pivot assembly (30) allows to operatively connect the trans-tibial member (14) to the knee member (12). A second pivot assembly (80) allows to operatively connect an upper end (16A) of the actuator (16) to the knee member (12). A third pivot assembly (100) allows to operatively connect a bottom end (16B) of the actuator (16) to the bottom end (14C) of the trans-tibial member (14). The prosthesis (10) can be provided as either a front actuator configuration or a rear actuator configuration.
