Definitions

  • Fig. 1 shows an ankle-foot prosthesis comprising a mechanical ankle (C) of rigid type and two rigid parts (1 and 2) pivoted under said ankle (C).
  • Another type of drawback of said ankle-foot prostheses consists in the fact that the design of the front rubber piece, in the first type of prosthesis, or the thickness of the carbon of the front part, in the second type of prosthesis, must be suitably made in order to find a correct compromise between two apparently opposite needs.
  • the prosthesis of the invention also comprises stop means to prohibit mutual rotation of the frame with respect to the bar beyond a predefined range of degrees, at least one elastic return member to maintain the front part of the frame normally raised and finally shock- absorbing means to slow down the lowering of the front part of the frame with respect to said pivoting means.
  • said box-shaped frame (102) is provided with a pair of longitudinal vertical borders (107) in adjacent parallel position, which are provided on top with ear (108) exactly where the malleolus of the foot is supposed to be situated.
  • the prosthesis of the invention also comprises stop means to prohibit the mutual rotation of the frame (102) with respect to the bar (100) beyond a predefined range of degrees exceeding the ones of a tibiotarsal articulation.
  • FIGS 7, 8 and 9 show a stop insert (1 1 1 ) disposed between the pair of longitudinal vertical borders in adjacent parallel position (107), which acts as stop for the extension travel of the piston (1 10).
  • said plate (1 12) is designed to be engaged under the frame (102), and precisely under the pair of longitudinal vertical borders in adjacent parallel position (107) that practically act as stop element at the end of the upper travel for the bending of said plate (1 12).

Abstract

Cette invention concerne une prothèse cheville-pied, qui comprend une barre (100) conçue pour se fixer à une jambe (A), un pied artificiel (P) monté pivotant à la base de ladite barre (100) et des moyens appropriés pour empêcher la rotation mutuelle du pied artificiel (P) par rapport à la barre (100) au-delà d'une plage prédéfinie de degrés, afin de reproduire une articulation tibiotarsale.
