| 摘要 |
The invention relates to a prosthetic or orthetic device (1, 1′) of the prosthesis or orthesis articulation module type, particularly for an ankle or ankle foot, comprising: —at least one upper fastening (7′, 7′″) and a lower fastening (7, 7″) connected to one another by at least two link rods (8; 8a, 8b), notably one (8a) at the front and one (8b) at the rear, —at least one articulation connecting the upper fastening (7′, 7′″) and the lower fastening (7, 7″), —at least one drive means (3, 3a, 3b, 5, 5′) connected to a link rod (8; 8a, 8b), secured to the upper fastening (7′, 7″) of the device (1, 1′) and able to move this link rod (8; 8a, 8b) so as to set the lower (7, 7″) and upper (7′, 7′″) fastenings in motion relative to their articulation, in which device the drive means is at least one eccentric (2; 2a, 2b) made to move by means of a cogged wheel (3; 3a, 3b) secured to the eccentric (2; 2a, 2b) and in mesh with an actuator.
