An orthopedic device for the orthotic or prosthetic provision of a patient. The orthopedic device includes a knee joint which has a proximal upper part and a distal lower part arranged pivotably thereon, an ankle joint, a pivoted foot part which can be fastened distally to the ankle joint, and a shin part arranged between the ankle joint and the knee joint. The upper part of the knee joint or a thigh part fastened thereto that can be attached to the patient's body and is coupled with the foot part by a force transfer device, which causes a plantar flexion of the foot part when a knee is flexed.

A mechanical grasping device where each of the segments of the finger assemblies, are individually sizeable. This allows for both a proportionately scalable grasping device as well as individual customization of geometric configurations tailored to specific use patterns. The mechanical grasping device is crushable since it has flexible and pivotable connections between digits along its length and width. It has a hollow member construction that imparts a strong lightweight design. It is modular so individual parts can be replaced for quick repair. From an aesthetics point, it is visually pleasing and can be offered in different colors, and with custom digit sleeves for specific applications. Finger assemblies can be operated individually or in groups via pairs of cables which allow operation in either voluntary open or voluntary closed modes of control. The flexible construction allows gripping of irregularly shaped objects and deforms before failing giving indication of overload prior to failure.

The invention relates to an orthopaedic device for the orthotic or prosthetic provision of a patient witha knee joint (10), which has a proximal upper part (11) and a distal lower part (13) arranged pivotably thereon, an ankle joint (20), a pivoted foot part (23) which can be fastened distally to the ankle joint (20), anda shin part (14) arranged between the ankle joint (20) and the knee joint (10), wherein the upper part (11) of the knee joint (10) or a thigh part fastened thereto that can be attached to the patient's body is coupled with the foot part (23) by means of a force transfer device (3; 30, 31, 32, 35; 40, 41, 42), which causes a plantar flexion of the foot part (23) when a knee is flexed.

An apparatus for assisting a finger motion, including a palm support installed to surround a part of a hand-back and a wrist; an extension assist unit secured at a first side thereof to a middle phalanx region of a finger and connected at a second side thereof to the palm support to assist extension of the finger through an elastic force between both ends; and a flexion assist unit comprising a distal phalange support mounted on an end of the finger, and a first flexion wire and a second flexion wire mounted on a part of the finger and assisting flexion of the finger on the basis of tensile force supplied from an outside.

An adjustable socket system includes a base, longitudinal supports connected to the base and extending along a longitudinal axis, and shell components operatively connected to the longitudinal supports and defining a receiving volume adapted to receive a residual limb. The adjustable socket system is radially expandable between open and closed configurations. The shell components include a first shell component having distal and proximal parts that are longitudinally displaceable with respect to one another such that a length of the first shell component is adjustable between a first length and a second length different than the first length.

A tendon device for a suit type robot which includes: a first wire and a second wire respectively fixed on a front portion and a rear portion of a joint of a user, and moving in a lengthwise direction thereof according to flexion-extension of the joint; a tendon driver including a first tendon module including a first pulley, and a second tendon module including a second pulley; a first pulley encoder measuring a rotary angle of the first pulley; a second pulley encoder for measuring a rotary angle of the second pulley; a controller configured to calculate tensions of the first wire and the second wire based on the rotary angle of the first and second pulleys in order to generate a control signal; and a driver configured to provide the first tendon module and the second tendon module with a driving power.

A prosthetic foot having a base spring having a toe end portion and a heel end portion, and a top spring assembly. The top spring assembly includes a first spring member having a distal end and a proximal end, a second spring member spaced apart from the first spring member along substantially an entire length of the first spring member, the second spring member having a distal end and a proximal end, a first bond connection provided between the distal ends of the first and second spring members, a second bond connection provided between the distal end of the second spring member and a top surface of the base spring in a forefoot portion of the base spring, and a spring connector extending through at least a first hole formed in the base spring, the second bond connection and the second spring member.

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.

The disclosed invention is an innovative, cost-efficient driving mechanism for the prosthetic hand industry that makes the use of only one motor to individually control each digit on a prosthetic hand separately. The use of the novel electromagnetic actuation system, locking mechanism, and spline nut and shaft configuration coupled with the single motor greatly reduces the weight, size and power usage of the prosthetic, increases functionality, minimizes noise, increases and speeds and forces, and orients the parts of the device in a manner that creates an aesthetically appealing design.

The present disclosure includes a finger exoskeleton including a plurality of joints and a plurality of sensors configured to measure rotation of at least some of the plurality of joints of the finger exoskeleton. The finger exoskeleton also includes a series elastic actuator comprising a spring element, the series elastic actuator configured to rotate at least one of the plurality of joints. The finger exoskeleton also includes a computing device configured to control operation of the series elastic actuator based on a torque of the at least one of the plurality of joints, the torque determined at least based on the spring element and rotation of the at least one of the plurality of joints. The present disclosure also includes associated methods and hand exoskeletons.
