Abstract: The invention relates to a method for producing a digital representation for producing an appliance for a living body, particularly to be applied against the external surface of the living body. The invention is particularly intended for the production of orthoses and prostheses. The method according to the invention allows the digital representation of an appliance using a modelling of the internal and external structures of the living body to be fitted with an appliance.

Abstract: A method for the radiographic imaging of a three-dimensional internal structure which forms part of an object located within a field of view, a radiographic image processing device and a radiographic imaging device, which are particularly suitable for locating a characteristic point of an internal structure on a radiographic image.

Abstract: Method for regulating a prosthesis (1), such as a knee prosthesis, ankle prosthesis or knee/ankle prosthesis, comprising at least one joint (2) controlled by an actuator (3) governed by a microcontroller (4) on the basis of data issuing from at least one gyroscope (5) and an accelerometer (6) that are able to measure the angular speed and the acceleration, respectively, of at least part of the prosthesis (1). According to the invention, the method is such that, during a defined period of time, the microcontroller (4) monitors the measurement given by the gyroscope (5), in such a way that said microcontroller (4) enters an idle state by reducing or by cutting the electrical power of at least one electronic organ of the prosthesis (1), except that of the accelerometer (6), when said microcontroller (4) detects that the absolute value of the measurement given by the gyroscope (5) is below a given threshold during the defined period of time.

Abstract: A prosthesis can include a femoral segment suitable for a femoral connection to a user and a tibial segment connected to the femoral segment based on an articulation which reproduces movements of the knee, the tibial segment being articulated on a foot segment based on an articulation reproducing movements of the ankle, a first hydraulic damper the ends of which are joined respectively with the femoral and tibial segments, and a second hydraulic damper of which the ends are joined respectively with the tibial and foot segments.

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.
