An orthopedic technical device having a top part and a bottom part, which are connected to each other by at least one joint device so as to be pivotable about a joint axis, and at least one attachment device with which the orthopedic technical device can be fixed to a limb. The orthopedic technical device also has an actuator, which is fixed to attachment points on the top part and the bottom part and influences a pivoting of the top part relative to the bottom part, wherein the orientation of the bottom part can be adjusted relative to the limb which is fixable to the upper part.

An orthopedic device comprises a main body defining an outer surface and a cuff extending from an end portion of the main body with frictional material disposed on an inner surface of the first cuff. A hinge is connected to the main body and terminates along the main body short of the cuff. The cuff is arranged to fold over the outer surface of the main body in a disengaged configuration, such that the outer surface of the first cuff is adjacently against the outer surface of the main body.

Disclosed is an electronically adjustable joint, and associated systems and methods. A joint position of a multiple-axis joint, e.g., a 3-axis joint, can be tracked, as the joint moves through two or more dimensions. In an illustrative embodiment, the joint can provide a mechanical equivalent of a physical joint, e.g., a shoulder, elbow, hip, or knee, which can accommodate motion in rotational angle and/or tilt angle. In some embodiments, the joint includes electronically adjustable friction. An illustrative application provides electronically adjustable joints for an aging simulation suit, wherein one or more joints can be controllably stiffened in selective ranges, such that a wearer of the suit can experience the effects of aging, arthritis and/or other ailments. In an illustrative embodiment, a sensor can use four discrete 2-axis magnetometers to calculate the position of the magnet on the arm of the joint, to continuously sense and track the angle of the joint. In some embodiments, the system includes a mechanism, e.g., a servo, which can controllably tighten a socket around a ball joint, wherein the system can controllably adjust friction on the joint.

An exoskeletal orthosis includes a proximal cuff including a hinge along an upper edge of the cuff; an ankle section/footplate; and at least one posterior strut connecting the proximal cuff to the ankle section and foot plate.

Hold-up devices for securing a leg brace from sliding or rotating on a patient's leg are provided. In various embodiments, a strap system for securing a leg brace includes at least one strap member for securing the hold-up device to a belt or waistband and includes multiple selectable mechanisms for attachment to a leg brace. In an example use scenario, a hold-up device has an adjustable strap, straps or strap-like member attachable to a belt, waistband or belt-like member around the patient's waist. The example hold-up device is connectable in various ways to the leg brace to prevent the brace from sliding down the patient's leg, from rotating on the patient's leg, or from both sliding and rotating on the patient's leg.

An orthosis with controlled angular excursion can be positioned at the level of a joint or articulation of the human body. The orthosis includes an articulated joint with a basic structure designed to be positioned on the joint and also includes centrally, a pin with toothing located in a circular sector with predetermined width. The basic structure and the relative pin provided with toothing are equipped with a respective pair of rings, each of which has a substantially elongated shape. A hollow part, or slot, includes two straight sectors, of which at least one is provided with toothing with the same pitch as the toothing of the pin with which it engages. The pair of rings can, when in use, be simultaneously rotated around the pin, and are provided with slots which in turn include a tractor for the orthosis.

A joint device of an orthosis with an upper part and with a lower part that is arranged on the upper part in an articulated manner, with a first fastening device for securing the upper part to a patient and a second fastening device for securing the lower part to a limb, wherein the joint device connects the upper part to the lower part in an articulated manner and has an upper part binding and a lower part binding via which the upper part and the lower part can be secured to the fastening devices, wherein the joint device has at least four degrees of freedom.

To provide a joint support unit, etc. capable of being worn on both left and right joints. A joint support unit includes a first link worn on one end side of a joint portion, a second link worn on the other end side of the joint portion, and rotatably coupled to the first link, a driving unit configured to perform rotation driving of the second link, and a rotation regulating unit configured to regulate a rotation direction and a rotation range of the second link. The rotation regulating unit includes an engagement body provided in one of the links, and an engagement part provided in the other one of the links, and engaging with the engagement body, the engagement part includes two guiding paths and that guide the engagement body moving according to the rotation direction of the second link in different directions, and a communication path.

An exoskeleton device in accordance with the present disclosure may generally include a series elastic actuator (SEA), a slider-crank mechanism and a four bar linkage mechanism. The SEA includes a motor and a ball screw coupled to a shaft of the motor via a shaft coupler, which transfers rotational motion of the shaft directly to the ball screw. The slider-crank mechanism includes a ball nut and a crank. As the ball screw rotates, the ball nut converts rotational motion of the ball screw into linear motion of the ball nut to drive the crank. The crank converts linear motion of the ball nut back into rotational motion at the input of the four bar linkage mechanism. The four bar linkage mechanism is coupled to an output of the crank and configured to provide a complex motion profile that emulates kinematics of a wearer's joint.

A knee brace includes a support module including a first body, a second body, and a hinge movably coupling the first body to the second body. The includes a pin on one of the first and second bodies, and a receptacle on the other of the first and second bodies. The receptacle is configured to receive the pin therein, such that the pin is rotatable and translatable within the receptacle. The knee brace also includes a fastener configured to releasably attach the knee brace to a leg. One of the first and second bodies couples with a first portion of the leg via the fastener, and the other of the first and second bodies couples with a second portion of the leg via the fastener. The first and second portions of the leg are separated by a knee joint of the leg.
