Title (EN) PROCESS AND APPARATUS FOR MAKING PROSTHESIS SOCKET
(FR) PROCEDE ET APPAREIL DE FABRICATION D'UNE EMBOITURE DE PROTHESE
Abstract:
(EN) The combination of compression pressure casting or molding a preformed, moldable, hardening socket material (36) and applying tension to a residual limb (40) in a distal direction while the socket material is curing results in forming a definitive socket that fits well to the residual limb after curing without substantial rectification. Pressure relief formations (90), socket coverings (92, 94), and a prosthesis coupler (38) may be compression molded simultaneously with the socket. A pressure casting system includes a pressure chamber (20), a compressive pressure applying membrane (22), a tension reacting system (58) for producing a resultant axial tension in the residual limb within the socket material during forming and hardening of the socket, and optionally a load cell (84) to monitor or indicate the tension force during molding. The socket material includes a preformed tubular sleeve like reinforcement web of fibers pre-impregnated with an uncured preferably water activatable, moldable, hardening resin material, with an integrated prosthesis coupler at one end.
(FR) Combiner la coulée sous pression de compression, ou le moulage d'une matière (36) pour emboîture préformée, pouvant être moulée et qui durcit, à l'application d'une tension à un moignon (40) dans une direction distale pendant le durcissement de la matière constituant l'emboîture, a pour résultat la formation d'une emboîture définitive qui s'adapte bien au moignon après durcissement, sans rectification notable. Des formations de réduction de la pression (90), des recouvrements d'emboîture (92, 94) et un coupleur (38) de prothèse peuvent être moulés par compression en même temps que l'emboîture. Un système de coulée sous pression comprend une chambre de pression (20), une membrane (22) d'application de la pression de compression, un système (58) de réaction à la tension pour produire une tension axiale résultante dans le moignon, à l'intérieur de la matière constituant l'emboîture, pendant sa mise en forme et son durcissment et facultativement une jauge de contrainte (84) pour surveiller ou indiquer la tension pendant le moulage. La matière constituant l'emboîture enrobe un manchon tubulaire préformé, fait par exemple d'une toile de renforcement ou de fibres préimprégnées avec une résine de durcissement non encore cuite qui, de préférence, peut être rendue active par l'eau et peut être moulée avec, à une extrémité, un coupleur de prothèse intégré.
