Walking motion assist device

A device for assisting a wearer in rotationally moving an ankle joint. A drive mechanism coaxially rotates with the ankle joint using a drive motor; a control device controls the drive motor. A storage stores a basic movement pattern and a corrected movement pattern that represent time-series changes in ankle joint angle in a gait cycled. A calculator obtains the corrected movement pattern by correcting the basic movement pattern based on input operation. The basic movement pattern is represented by a polygonal line or a Bézier curve, each of which includes a plurality of predetermined points serving as inflection points, or a combination of thereof. The calculator generates the corrected movement pattern corrected by adjusting positions of the plurality of predetermined points on the basic movement pattern, and, based on the corrected movement pattern, the control device controls driving provided by the drive motor.

20220000649 · 2022-01-06 · ·

A method for producing a hand orthosis, including the steps of: Producing an impression of at least one finger of a patient's hand and at least a part of a forearm, producing a finger section from a reproduction based on the impression, incorporating at least one finger segment in the finger section side corresponding to the hand surface, detecting the physiology of the patient's forearm using at least one captured image from the reproduction together with the finger section, thereby producing a digital 3D model, generating a rail based on the produced digital 3D model, securing at least one force-introducer onto or into the rail, securing a proximal end of the at least one finger segment to a distal end of the rail, and coupling the at least one force-introducer to the at least one finger segment. A hand orthosis is also provided.

LOAD-DETECTING ORTHOSIS
20220000392 · 2022-01-06 ·

A loading-detecting orthosis includes a sensor that generates sensor signals and that has sensor elements in pressure areas. The loading-detecting orthosis further includes sensor signal-evaluating electronics that are designed to indicate critical loading. The sensor signal-evaluating electronics are designed to ascertain characteristic values regarding pressure loading events detected at least per pressure area by way of the sensor elements, to form a sum value into which the characteristic values are incorporated by amount in weighted form such that at least three different weights are used, and to generate an alert signal when the sum value exceeds a certain amount.

Lower-leg exoskeleton system and method

A lower-leg exoskeleton that includes an inflatable actuator configured to be worn over a front portion of a leg of a user and configured to be disposed directly adjacent to and surrounding a joint of the leg of the user. The inflatable actuator is configured, when worn by the user, to receive and transmit an actuator load generated by the inflatable actuator around the joint of the user to a load contact point. Inflation of the inflatable actuator generates a moment about the joint of the user to cause flexion of the leg of the user.

Self-Donning Powered Orthotic Device

A powered orthotic device includes a brace, a finger engagement member, a thumb engagement member, and a hand actuator. The powered orthotic device includes an affixment member affixed to the brace, and a finger carrier assembly with a finger carrier to engage the fingers of the wearer, as well as a locking mechanism configured to be removably attached to the affixment member. The wearer dons the orthotic device, without assistance from another, by placing the set of fingers into the finger carrier and using a free hand of the wearer to affix the locking mechanism to the affixment member.

Joint device

A joint device of an orthosis or prosthesis or for an orthosis or prosthesis with an upper part, a lower part, a joint that comprises a joint axis, about which the upper part is mounted such that it can be swivelled relative to the lower part, and an actuator, which is designed to influence a swivelling of the upper part relative to the lower part. The actuator is mounted at an upper part fixing point on the upper part and at a lower part fixing point on the lower part. At least two joints are arranged between the upper part fixing point and the lower part fixing point, wherein the joints enable a swivelling of the actuator relative to the upper part fixing point and the lower part fixing point, and the joints each form at least one joint axis, at least one of which is not oriented parallel to the joint axis.

Foot for a robotic exoskeleton for assisted walking of persons suffering from locomotor disorders

A foot for a robotic exoskeleton includes three rigid foot segments, namely a middle foot segment arranged to be connected to a leg of the robotic exoskeleton, a front foot segment elastically connected to the front end of the middle foot segment by a first set of leaf springs and a rear foot segment elastically connected to the rear end of the middle foot segment by a second set of leaf springs. The foot has laces for fastening the foot to a person's shoe. In the condition where the front foot segment and the rear foot segment are both in contact with the ground, and no load is applied onto the foot, the middle foot segment is not in contact with the ground, but is elastically suspended by the first and second sets of springs.

Tiltable articulated joint brace
11771576 · 2023-10-03 · ·

The disclosure relates to a tiltable joint brace for a joint orthesis, comprising: two articulated limbs pivotably mounted on each other in a bearing arrangement, wherein the head of the first articulated limb supports a bearing arrangement which can be connected to the head of the second articulated limb by non-positive and positive fit in order to form the pivot joint. A curved sliding surface is formed on the bearing arrangement, and the head rests on the curved sliding surface with positive fit. There, the second articulated limb can tilt freely toward the pivot axis of the joint brace against the first articulated limb.

ADAPTIVE ARM SUPPORT SYSTEMS AND METHODS FOR USE
20220401283 · 2022-12-22 ·

A system is provided for supporting an arm of a user that includes a harness configured to be worn by the user, and an arm support coupled to the harness and including an arm rest to support an arm of the user. The arm support is configured to accommodate and follow movement of the arm without substantially interfering in such movement. The arm support may at least partially offset a gravitational force acting on the arm as the user moves and the arm support follows the movement of the user's arm. For example, the arm support may transfer at least a portion of the weight of the user's arm to the torso or other region of the user's body and/or may apply an opposing force to at least partially offset the gravitational force acting on the arm.

Semi-active robotic joint

A robotic joint comprises a first link, a middle link, a torque generator, a second link, and a locking mechanism. Different ends of the middle link are rotatably coupled to the first link and the second link. The torque generator is coupled to the first link and the middle link and is configured to produce torque between these links. The locking mechanism is switchable between a locking state and an unlocking state. In the unlocking state, the locking mechanism allows free rotation of the second link relative to the middle link in the first and second rotation directions. In the locking state, the locking mechanism is configured to impede rotation of the second link relative to the middle link in the first rotation direction and to allow rotation of the second link relative to the middle link in the second rotation direction opposite of the first rotation direction.
