摘要:
The present invention refers to an automatic knee prosthesis possessing flexion-extension movements, and axial passive rotation, medial and lateral of the type comprising first connecting means for fixing the prosthesis to a stump or socket support of a person amputated from a lower limb. Also, it includes articulation means for simulating a knee flexion-extension movement, and second connection means for securing the prosthesis to an element simulating the distal end of a lower member. Besides, is composed by axial rotation means located within the first connecting means to permit the change in the plane of the prosthesis concerning the trunnion support, and motor means located between the articulation means and the second connection means, for moving the articulation means. Moreover, it comprises sensors that measure the orientation in space, the stroke position of the flexion-extension movement and the acceleration of the prosthesis and the muscular activity of the amputated person . Finally, it is composed by an integrated circuit that receives the parameters measured by the sensors calculates the position of the prosthesis and determines the energy that the motor means must generate for the prosthesis to perform the movement stimulated by the amputee.Se ha inventado una prótesis automática de rodilla con movimientos de flexión-extensión y rotación pasiva automática axial, medial y lateral del tipo que comprende primeros medios de conexión para fijar la prótesis a un soporte de muñón o "socket" de una persona amputada de un miembro inferior; medios de articulación para simular un movimiento de flexión-extensión de rodilla; y segundos medios de conexión para fijar la prótesis a un elemento que simule el extremo distal de un miembro inferior; la cual además también comprende medios de rotación axial localizados dentro de los primeros medios de conexión para permitir el cambio de plano de la prótesis con respecto al soporte de muñón; medios motrices localizados ent
