Joint and digit

This disclosure relates to the field of prosthetics, more specifically to a pinless anthropomorphic hinge or joint, and a digit comprising one or more phalanges connected by and articulating around pinless joints, whereby the joints provide compliant movement in more than one plane. This disclosure also relates to modular prosthetic systems comprising multiple digits, in particular for partial-hand replacements.

ADJUSTABLE SOCKET SYSTEM

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.

ADJUSTABLE SOCKET SYSTEM

An adjustable socket system includes a plurality of shell components and longitudinal supports connected to a base and is movable between an open configuration to loosen the fit of the adjustable socket system, and a closed configuration to secure the fit of the adjustable socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point and to the shell components via a control point. Rotation of the handle displace the movable connection point and the tensioning element relative to the control point to move the adjustable socket system to the closed configuration.

JOINT PROSTHESIS

It is provided a joint prosthesis (1) configured to reciprocally rotate a first prosthesis (1a) and a second prosthesis (1b) and comprising: a first attachment (2) to the first prosthesis (1a); a second attachment (3) to the second prosthesis (1b): a hinge (4) defining an axis of rotation (4a) between the attachments (2, 3); a mover (5) configured to apply to the hinge (4) a driving torque defining a reciprocal rotation between the attachments (2, 3); and a compensator (6) configured to apply to the hinge (4) a variable locking torque depending on the angular opening between the attachments (2, 3) and defining the minimum torque to be applied to the hinge (4) to have said reciprocal rotation.

Orthopedic device

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 means of a force transfer device, which causes a plantar flexion of the foot part when a knee is flexed.

Harness for Upper Extremity Below-Elbow Prosthesis
20180140442 · 2018-05-24 ·

A harness for an upper extremity below-elbow prosthesis. The harness includes a humeral cuff having medial and lateral pivot arms configured to removably attach to the socket of a below-elbow prosthesis. The humeral cuff enables a user to suspend the prosthesis without the need of a shoulder strap/harness or body harness. A cable system is affixed to the pivot arms and includes a wheel coupling the pivot arms to the control arm of a hook of the below-elbow prosthesis, thereby enabling users to operate the hook by simple flexion and extension of their arm.

Electromagnetic actuation mechanism for individual digit control of an artificial hand
09974667 · 2018-05-22 ·

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 magnetic 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.

Hydraulic Pump Assembly for Artificial Hand
20180133032 · 2018-05-17 ·

A hydraulic pump assembly (72) comprises: a low-pressure hydraulic pump (74), a high-pressure hydraulic pump (76), and a drive shaft assembly (78) that passes along an axis of the pump assembly (72); wherein both hydraulic pumps (74, 76) are arranged to be rotated simultaneously by the drive shaft assembly (78); and wherein the pump assembly (72) is formed a single unit arranged to fit into a pump chamber (80).

TENDON DEVICE FOR SUIT TYPE ROBOT FOR ASSISTING HUMAN WITH PHYSICAL STRENGTH
20180116851 · 2018-05-03 ·

Provided is 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.
