GIUNTO ROBOTICO PER ARTICOLAZIONE PROTESICA

The present invention refers to a module of flexion-extension (1000) for an artificial articulation (10), comprising: a proximal base element (1 ), configured to connect to a prosthetic socket (100); a distal base element (2), configured to connect to a prosthesis (101 ); mechanical connection means (20) of the proximal base element (1 ) to the distal base element (2), configured in such a way as to allow a rotation of the distal base element (2) with respect to the proximal base element (1 ) in such a way as to realize a movement of flexion-extension of the prosthesis (101) with respect to the socket (100); stressing means (6) connected to the mechanical connection means (20) and to respective elastic reaction means (40) configured to exert a reaction force apt to counteract the rotation of the distal base element (2) wherein said mechanical connection means (20) comprises at least one Scotch- Yoke mechanism suitable for transforming a rotary motion of the distal base element (2) into a linear motion of the stressing means (6), such that when the means of mechanical connection means (20) is operated, the stressing means (6) is linearly moved to elastically deform said elastic reaction means (40), and when the mechanical connection means (20) is not operated, the elastic reaction means (40) is configured to maintain the proximal base element (1 ) and the distal base element (2) in a rest configuration.
