The invention relates to a method for creating manufacturing data for manufacturing an orthopedic product for a body part of a patient, the method comprising the following steps: providing a digital three-dimensional body part model of the relevant body part for which the orthopedic product is destined to an electronic data processing apparatus, the three-dimensional body part model being based on external body part data acquired from the body part of the patient; identifying at least one rigid body part region in the provided body part model by means of the electronic data processing apparatus, with the remaining region situated outside of the rigid body part region being identified as a yielding body part region on the basis of the identified rigid body part region; creating a reduced three-dimensional body part model by means of the electronic data processing apparatus on the basis of the provided three-dimensional body part model, the identified rigid body part regions and a reduction metric applied in the region of the yielding body part region; and producing manufacturing data for the orthopedic product on the basis of the reduced three-dimensional body part model by means of the electronic data processing apparatus.

A prosthetic limb includes: a socket as a thigh part; a thigh joint part provided on a side of the socket; a lower leg part coupled to the thigh joint part and provided to be rotatable around a knee shaft; a thigh part inclination angle acquisition unit that acquires an inclination angle Ψ formed by the socket relative to a vertical line passing through the knee shaft; and a rotational resistance control unit that weakens a rotational resistance of the knee shaft in accordance with a transition from a positive inclination angle formed when the socket is inclined rearward relative to the vertical line to a negative inclination angle formed when the socket is inclined forward relative to the vertical line.

A covering shell for a prosthesis of a given limb, the shell having at least two zones of different flexibility. The arrangement of the zones of the covering shell in relation to one another corresponding to the arrangement of the parts of the given limb having different hardnesses. An exoskeletal structure, having preferably a tubular shape, of a prosthesis of a given limb. The exoskeletal structure being designed to provide a connection between a socket and a hand prosthesis or between a socket and a foot prosthesis, in order to form the prosthesis of the limb. The exoskeletal structure having at least two zones of different flexibility. The arrangement of the zones of the exoskeletal structure in relation to one another corresponding to the arrangement of the parts of the given limb having different hardnesses.

Provided is a wearable assisted-walking device including one lower attachment body to the foot defining a lower anchoring point at the heel of the foot of a leg of the user; an upper attachment body to an upper part of the leg proximal from the knee defining an upper ventral anchoring point and an upper dorsal anchoring point arranged on the opposite side of the coronal plane of the user; and an intermediate attachment body defining a first intermediate anchoring point, a second intermediate anchoring point and a third intermediate anchoring point, each anchoring point movable respect and connected by cables to the leg; the intermediate attachment body being adapted to store the energy by a relative motion between the anchoring points and then use it for assist walking.

An implant assembly for a long bone having a longitudinal axis. The implant assembly has a stem that is received in a surgically prepared medullary canal of the long bone. The stem defines at least one transverse through-opening that extends through the stem from a first portion of the outer surface of the stem to an opposed second portion of the outer surface of the stem. Each transverse through-opening has a central axis that is substantially perpendicular to the longitudinal axis of the stem. Each transverse through-opening receives a fastener and has a longitudinal dimension, measured relative to the longitudinal axis of the stem, that is sufficient to permit axial movement, relative to the longitudinal axis of the stem, of the stem relative to each fastener.

A system can be used to record real-time pressure and/or shear force data within a socket for a prosthetic device. The system includes a socket for a prosthetic device that can be designed to fit a patient's residual limb. The system also includes a sensor array that can be placed within the socket for the prosthetic device to detect pressure and/or shear force on the patient's residual limb. The sensor array includes a piezo-electric material and a uniform distribution of a plurality of metal pads on either side of the piezo-electric material. Each of the plurality of metal pads on either side of the piezo-electric material comprises at least one wire connected to a common port.

Systems and methods for controlling a passive prosthetic knee joint with adjustable damping in the direction of flexion such that a prosthetic unit attached to the knee joint can be adapted for climbing stairs.

Prosthetic coupling interfaces and methods of use are disclosed herein. An example system can include an external fixator apparatus, a prosthetic appendage assembly, and a prosthetic coupling interface for connecting the external fixator apparatus with the prosthetic appendage assembly.

A prosthetic system includes a prosthetic foot defining an upper surface and having a flexible configuration and a pump system attached to the prosthetic foot. The pump system includes a pump mechanism defining a fluid chamber having variable configuration and an actuating part. The actuating part is arranged to selectively engage with and separate a distance from the upper surface of the foot plate to move the pump mechanism between a first position in which a volume of the fluid chamber is zero or near-zero and a second position in which the volume of the fluid chamber is expanded relative to the first position. The volume of the fluid chamber increases when the actuating part moves away from the upper surface of the foot plate.

The present invention provides a mechanical prosthetic limb, which relates to the technical field of medical devices. The mechanical prosthetic limb includes a prosthetic limb shank, a fixed component for connecting the prosthetic limb shank with a human body, a power-driven first drive mechanism that is installed on the prosthetic limb shank, and a prosthetic limb sole that is connected to the bottom of the prosthetic limb shank; the fixed component is rotationally connected with the prosthetic limb shank through the first drive mechanism; and the prosthetic limb shank is rotationally connected with the prosthetic limb sole through the first drive mechanism. It can relieve the burdens of the disabled in the automatic advance way, thereby improving convenience.
