| 摘要 |
<p>The present invention is a lower extremity prosthetic device (10) which includes a modular foot (14) having a heel member (28) and an elongate, dorsal midfoot member (30) configured for detachable combination via a coupling mechanism. The heel member is formed from a first structural material of a first modulus of elasticity. The midfoot member is formed from a second structural material having a second modulus of elasticity less than the first modulus of elasticity. The midfoot member extends arcuately forwardly from the heel member and is configured with differentially flexible lateral and medial elements (30a, 30b). An elongate plantar member (32) extends between the heel member and a forward end of the midfoot member and is formed from a third material having a third modulus of elasticity which is lower than the second modulus of elasticity. The plantar member includes a toe section (33) and a sub-arch section (34).</p> |
