Abstract: The present invention pertains to a femoral knee-ankle prosthesis intended for persons who are lower-limb amputees but still have a segment suitable for a femoral connection and a tibial connection connected to the femoral segment based on an articulation which reproduces the movements of the knee, the said tibial segment being articulated on one foot based on an articulation reproducing the movements of the ankle, an initial damper the ends of which are joined respectively with the femoral and tibial segments, and another hydraulic damper of which the ends are joined respectively with the tibial and foot segment; the said prosthesis is remarkable in that the chamber of the first hydraulic damper is connected to the chamber of the second hydraulic damper and in that it consists of the means of controlling the first and/or second hydraulic damper depending on the phase of the walking cycle such as the stance phase or the swing phase and/or real-life situations such as stairs, slopes or standing, etc.
Abstract: 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.
Abstract: A process for manufacturing a flexible sleeve for a prosthesis or orthesis, including selecting sleeve preform (2) which consists of flexible thermoformable material and having approximately conical or cylindrical shape with a closed end of rounded shape the dimensions of which are matched to those of the stump or stump replica to be fitted with the prosthesis or with the orthesis; heating the preform (2) until it softens; slipping the softened preform over the stump or over the stump replica (1); conforming the shape of the softened preform (2) to that of the stump or of its replica (1); leaving the preform (2) to cool on the stump or on the replica; and removing the cooled preform which constitutes the finished sleeve from the stump or the stump replica.
Abstract: A halo adapted to enclose the forehead and temples of a patient including at least two frontotemporal bars (1) which are joined to each other, and two half-arches (2) which are joined to each other and are fixed connected with the frontotemporal bars, the joined half-arches forming an arch enclosing the posterosuperior zone of the cranium of the patient. The frontotemporal bars (1) and the half-arches (2) are interconnected through bars (4, 5) overlapping the contiguous ends of the former. The mutually facing portions of the frontotemporal bars, the half-arches and the interconnecting bars include orifices (7, 8, 9, 10, 11, 12) facilitating rigid fastening together thereof by assembly screws (6). At least some of the orifices of the interconnecting bars, the frontotemporal bars, and the half-arches being oblong slots (7, 8, 12), facilitating adapting the dimensions of the halo to the morphology of the cranium of the patient.

Abstract: A system for assembling two components of a prosthesis in a plurality of positions which are adjustable in orthogonal translation, and selectively in rotation and angularly. In the system, a projecting part integral with one of these components is engaged in a recess, forming a hollow part of the other component of the prosthesis, or of an intermediate connection element, while screws arranged transversely with respect to the lateral walls of the cell come into abutment, as in the prior art, against the lateral flanks of the projecting part, but without the base of the hollow part bearing directly against the facing surface of the projecting part.
Abstract: A device has a valve (21) activated by hydraulic fluid in opposition to a resilient restoring element (27) and blocking off an outlet in the bottom of a cylinder ( 3 ) when the fluid, responsive to being compressed by a piston (5), exerts a specified pressure subsequent to an involuntary movement on the part of a femoral amputee wearing the device so as to correct the gait of the amputee.
Abstract: The invention relates to a prosthesis for a leg amputee, comprising a thermoformed framework made of a thermoplastic material or of a laminated substance, covered with a coating material and comprising a socket (1), a leg part (2) and a prosthetic foot (3), one adjoining the other.According to the invention, the framework of the leg part (2) and the prosthetic foot (3) constitutes a monobloc assembly, produced in a single casting operation, and in that the prosthetic foot comprises, at the level of the sole, a cut having served for the extraction of the molding core and, at the level of the heel, above the sole, a cut (9) of wedge formation lending itself to a flexion of the rear of the sole relative to the leg part.
Abstract: The invention relates to an apparatus for plotting the conformation of a lower limb of the human body, this apparatus comprising two sets of two longitudinal uprights, or splints (1), the splints of one and the same set being mutually articulated by an orthesis articulation (2) of a known type, and a plurality of cross-pieces forming braces (8, 10, 12) which transversely connect the splints (1) at various intervals. According to the invention, the spints (1) are deforable in such a way that they can be applied tighlty agains the limb in question in order to match the profile thereof, and the crosspieces (8, 10, 12) connecting these splints have an adjustable transverse dimension, so as to be able to regulate the spacing of the splints.
Abstract: The invention relates to a prosthesis for amputation of the leg.This prosthesis comprises, in monobloc form:a socket (1) of a thermosettable resin, preferably provided with reinforcement fibers;a hollow leg element (2) rigidly integral with the socket, likewise of a thermosettable resin, preferably provided with reinforcement fibers;a hollow foot part (3) rigidly integral with the leg element (2), and in which is lodged a rigid core (26) of a foam of plastic material or similar, this foot part being likewise of a thermosettable material, preferably provided with reinforcement fibers;a sole element (4) of a thermosettable resin, preferably provided with reinforcement fibers, closing the hollow foot part at its base.
Abstract: The device for the alignment research, the alignment and orientation of a first portion of a prosthesis with respect to second portion of said prosthesis comprises at least three elements, two of said elements having spherical contact surfaces and two of said elements having flat contact surfaces, said elements being interposed between said first and second portions of prosthesis and moved one with respect to the other to adjust the respective positioning and orientation of said two portions of prosthesis.
