A prosthetic ankle has an ankle joint body (10A) constituting a shin component and a foot component (12). The ankle joint body (10A) is pivotally connected to the foot component (12) by a first pivotal connection (14) defining a medial-lateral ankle joint flexion axis. The ankle joint body (10A) also forms the cylinder of an ankle joint piston and cylinder assembly with a superior-inferior central axis, the cylinder housing a piston (16) with upper and lower piston rods (16A, 16B). The lower piston rod (16B) is pivotally connected to the foot component (12) at a second pivotal connection (18). As the ankle joint body (10A) pivots about the ankle joint flexion axis, the piston (16) moves substantially linearly in the cylinder formed by the ankle joint body. The cylinder is divided into upper and lower chambers (20A, 20B). These chambers are linked by an hydraulic circuit (22) incorporating passages (22A, 22B) in the ankle joint body (10A), and an energy conversion device in the form of a slave piston and cylinder assembly (24) having a piston (24P) and piston rods (24R) which project beyond the cylinder (24C) of the assembly (24).

An assist garment is configured to be worn on a part of a human body and includes a plurality of garment-fitting actuators placed linearly along at least one end portion of a garment body and configured to be driven to extend and contract, a plurality of assisting actuators placed linearly on the garment body to cross the plurality of garment-fitting actuators and configured to be driven to extend and contract, and a controller configured to individually control driving of the plurality of assisting actuators and driving of the plurality of garment-fitting actuators.

A method for manufacturing an orthopedic product for a body part of a patient is disclosed, the method comprising the following steps: a) providing body-part data containing information about an internal structure of the body part, b) detecting a current line of vision from which a user of the method sees the body part, c) displaying the body part data from the current line of vision by means of the display device so that the user sees the body part and the body part data superimposed, d) generating production data for the orthopedic device on the basis of the displayed data and e) providing an orthopedic product manufactured on the basis of the production data.

An under-driven prosthetic hand with a self-adaptive grasping function is provided, which belongs to the field of medical equipment. The prosthetic hand simultaneously controls four fingers to implement bending and stretching movements by a first motor through structural designs of a prosthetic hand body, a finger transmission module, an inter-finger transmission module, and a thumb driving module, and limits the transmission torque between the motor and screws using a damping shaft and in cooperation with the telescopic characteristic of a telescopic component. On the one hand, mechanical damage to the prosthetic hand structure due to excessive torque outputted by the motor can be prevented. On the other hand, the self-adaptive grasping function of the prosthetic hand can be implemented. The disclosure can also effectively solve issues such as excessive volume or mass of the prosthetic hand, complicated control system, and low operation precision.

A method for reducing motion of a skeletal structure in a limb towards a wall of an interface is described. The interface comprises a plurality of compression areas that are longitudinally-shaped and oriented longitudinally along the length of limb. The method comprises selecting, during a process of creating the interface, a compression level for the compression areas that compresses soft tissue against the skeletal structure. The method also comprises donning the interface over the limb to apply a plurality of compressive forces that is sufficient to aid in suspension of the interface on the limb and reduce motion of the skeletal structure toward a wall of the interface.

Prosthesis devices can include sockets having adjustable features. In one example, a socket includes one or more panels that can move outwardly or inwardly relative to a receptacle portion of the socket. The panels can be moved by tightening a tensioning line.

Disclosed herein are a method and system for producing a digital model of a customised device, comprising the steps of: importing a first digital file of a base part; importing a second digital file of a target shape; determining a warping interpolation function based on source point positions associated with the base part and target point positions associated with the target shape; and applying the warping interpolation function to the points of said base part to generate a model of said customised device.

A strain sensor includes a flexible substrate and a circuit disposed on the flexible substrate. The circuit includes an inductance to receive an excitation signal, the circuit being configured to generate a radio frequency response to the excitation signal via the inductance. The circuit includes an elongated trace coupled to the inductance and configured to bend and stretch longitudinally upon deformation of the flexible substrate. The elongated trace includes a non-uniformity configured such that the elongated trace deforms and tears at the non-uniformity and exhibits a non-linear increase in resistance as a tensile strain to which the elongated trace is subjected reaches a strain threshold. The non-linear increase in resistance modifies a characteristic of the radio frequency response of the circuit.

A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.
