Prosthetic limbs

摘要

A prosthetic limb system comprises a prosthetic limb and activation means therefor attachable to an amputee stump, in which the activation means comprises means for sensing myoelectric signals generated at the stump surface by specified muscles, means for filtering the sensed signals, means for inputting the filtered signals to an artificial neural network and means within said neural network for classifying input signals with muscle contractions representative of desired digit movements; and the prosthetic limb comprises servo-drive means to enable digits thereof to perform specified mechanical movements, said classified signals being operatively connected to said servo-drive means to enable one or more of said digits to perform an actual movement on receipt of an appropriate desired movement from said artificial neural network. <IMAGE>
