GAIT MOTION ASSISTING APPARATUS
A gait motion assisting apparatus of the present invention includes a casing attachable to right and left knee ankle foot orthoses, an electric motor, a drive arm having a proximal end driven around a drive-side pivot axis by driving force from the electric motor and a distal end operatively connected to a lower leg frame of the orthosis, a rotation sensor detecting a swinging position of the drive arm around the drive-side pivot axis, a gait motion state detection sensor and a control device. The control device recognizes as a reference value a detection signal from the rotation sensor when the lower leg is fully extended, and judges right or left of leg to which the orthosis is mounted based on a detection signal other than the reference value to select right or left of assisting force control data used when calculating assisting force to be output from the electric motor.
ANKLE ORTHOSIS
A multi-axis rotation control ankle brace, wherein the direction and magnitude of force can be controlled around three axes of the ankle joint through an adjustable tensioning apparatus. The device may be applied to address conditions such as chronic ankle instability, foot drop, or osteoarthritis by providing such forces around the joint as an external-muscle tendon system to improve function, reduce pain, or restore mobility of the user. While more are contemplated herein, five preferred embodiments are specifically disclosed in the current application. Three preferred embodiments comprise a proximal portion and a distal portion, wherein the proximal portion is anchored above the ankle joint and houses, in aspects, the adjustment mechanism. The proximal portion is connected to the distal portion by tensioning or compressive elements, through which forces can be controlled by the user via the adjustment mechanism. In other preferred embodiments, the device is comprised of one continuous mesh, sock or sleeve through which tension can be controlled by the user. In other preferred embodiments, the device is personalized to the user through multiple aspects including user-enabled adjustment of forces around the joint. The device may be customized by 3D printing a device based on a digital scan, and therefore conforms to the user's ankle and foot.
ORTHOSIS OR EXOSKELETON SYSTEM
An orthosis or exoskeleton system can be mounted proximate a user's joint. The system includes a brace, which includes a first body mounting portion to be mounted to one side of the user's joint and a second body mounting portion to be mounted to an opposite side of the user's joint. The first and second mounting portions are moveably coupled together. A range of motion (ROM) limitation mechanism presents a number of selectable ROM limits between the first and second body mounting portions. One or more sensors detect a user's kinematics and/or kinetics. The system is configurable during use based on the user's kinematics and/or kinetics, including by setting or updating the ROM limitation mechanism from a present ROM limit setting to a new ROM limit setting.
Mechanical assisted active orthosis using a robotic application
A knee orthosis provides varying levels of support to a patient during a stance phase and a swing phase of a gait cycle. The orthosis comprises an upper auxiliary support, a lower auxiliary support, an actuator, a sensor configured to detect a plurality of leg movements during the gait cycle and to output a plurality of detection signals corresponding to the detected leg movements, and a processor configured to determine whether the knee is in the stance phase or the swing phase of the gait cycle, to control the actuator to apply pressure on the lower auxiliary support when the knee is in the stance phase, and to release pressure when the knee is in the swing phase.
GAIT MOTION ASSISTING APPARATUS
A gait motion assisting apparatus of the present invention can be connected to a knee-ankle-foot orthosis at three different positions in a vertical direction by upper, intermediate and lower connecting mechanisms. The intermediate connecting mechanism includes a ball stud arranged at the knee-ankle-foot orthosis extending outward in the user width direction on a brace-side pivot axis line X and an accommodation depression opened toward the knee-ankle-foot orthosis on the actuator-side pivot axis line Y so that the ball stud can be inserted thereinto. The accommodation depression is arranged at an innermost power-transmitting member among a driving arm and components of a transmission mechanism operatively transmitting rotational power from an electric motor to the driving arm.
JOINT ORTHOSIS ASSEMBLY
A joint orthosis assembly includes a web, an arm unit, a strap unit, and at least one fastening subassembly. The web has three web portions for being wrapped on an upper limb structure, a lower limb structure, and a joint between the upper and lower limb structures, respectively. The arm unit is retained on the web and includes two arms which are pivotally connected, and which are for being disposed at lateral sides of the upper and lower limb structures, respectively. The strap unit includes two straps each being wound about the web to be coupled between the two arms. The fastening subassembly is configured to permit an end of at least one of the straps to be turnably coupled to a corresponding one of arms.
Frame assembly and motion assistance apparatus including the same
A frame assembly includes a first longitudinal member, a second longitudinal member spaced apart from the first longitudinal member, and a plurality of distance maintaining members connected between the first longitudinal member and the second longitudinal member, and configured to maintain a distance between the first longitudinal member and the second longitudinal member.
Method for automating custom-fitting joint brace
An automated method for applying specific geometric constraints to a starter file and considering external specifications outside of fit to achieve an optimized, restorative joint brace or orthotic device. External specifications may include indications of the patient, biometric data, data from prescribing doctors, X-ray data, MRI data, joint geometry to restore optimized function, and envelope of motion. After the fitting process, the starter file undergoes a process of exact commands in order to finish and/or add additional features. With a vertical integration from scanning an object to producing the custom fitted device, the product can be manufactured at scale more rapidly and at lower cost, improving access to superior devices at a reasonable price to the consumer.
Orthopedic brace securing and tensioning system
An attachment system for an orthopedic brace incorporates at least one cinching system assembly having a knob rotatable in a first direction and a second direction. At least one cinching plate is engaged by the knob for rotation in the first direction in a first orientation and transitions to a second orientation upon rotation in the second direction. A ratchet wheel is engaged by the cinching plate in the first orientation for rotation in the first direction. At least one ratchet arm engages the ratchet wheel for ratcheting operation and is engaged by the cinching plate in the second orientation for disengagement from the ratchet arm. A shaft is rotated in response to rotation of the ratchet wheel and a strap is extendible from and retractable on the shaft upon rotation of the shaft.
CUSTOMIZABLE KNEE BRACE INTENDED FOR PATIENTS WITH OSTEOARTHRITIS
A customizable knee brace for use in the treatment of osteoarthritis is provided. The customizable knee brace includes a lateral upright. The lateral upright includes at least a first semi-rigid support, a second semi-rigid support, and a hinge physically coupling the first semi-rigid support and the second semi-rigid support. The customizable knee brace further includes a thigh cuff constructed of formable material and coupled to the first semi-rigid support. The customizable knee brace further includes a shin cuff constructed of formable material and coupled to the second semi-rigid support. The customizable knee brace further includes an elastomeric web framework coupled to the lateral upright and configured to secure an area of a knee of a patient when wearing the customizable knee brace. The customizable knee brace further includes at least one tensioning element configured to adjust a tension of the elastomeric web framework.
