STAIR DESCENT CONTROL FOR POWERED LOWER LIMB DEVICES
20220054285 · 2022-02-24 ·

Systems and methods of operating a lower limb device having at least a powered joint are provided. A method includes configuring the device to a first state in a finite state model for a current activity mode including a stair ascent mode or a stair descent mode. The method also includes, based on real-time sensor information, transitioning the device between different states in the finite state model when pre-defined criteria for transitioning among the different states are met. In the method, the finite state model for stair ascent includes lifting and swing phases, where the lifting phase includes a powered knee extension and a powered ankle push-off. The finite state model for stair descent includes yielding and swing states, where the swing states include providing a powered plantarflexion of the powered ankle joint and the yielding states include providing a resistive and passive plantarflexion of the powered ankle joint.

METHOD FOR EVALUATING USAGE DATA

The invention relates to a method for evaluating usage data of at least one orthopaedic device which is equipped with sensors for detecting properties, states, or changes in properties or states, wherein the sensors are connected to a transmitter directly or via a storage device and the transmitter transmits the sensor data provided by the sensors to an evaluation unit in a computer network in which the sensor data is processed.

PROSTHESIS

A prosthesis with a support part on which a pivot joint is secured or formed. A distal prosthesis component is secured to the support part via the pivot joint, and the pivot joint allows a flexion and extension of the distal prosthesis component about a pivot axis relative to the receiving element or to the support part. A damping device, spring device, and/or actuator is arranged between the distal prosthesis component and the support part, and the damping device, spring device, and/or actuator is mounted on the distal prosthesis component using a first bearing point and is mounted on a lever or an arm using a second bearing point. The lever is mounted on the distal prosthesis component in a pivotal manner about a pivot axis. A distal portion of the arm is mounted on the lever, and a proximal portion is mounted on the support part.

Anti-microbial irradiation for percutaneous osseointegrated prostheses (POPs)

An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.

Prosthetic suspension mounting assembly
11253377 · 2022-02-22 · ·

A prosthetic suspension-mounting system which employs an improved flathead bolt and socket centering cup combination for securement of an amputee-limb enveloping liner within a prosthesis. The liner has a strap fixedly attached on the bottom end of the liner by a flathead bolt. The mounting system also includes a containment socket for seating the liner in the prosthesis using the head of the flathead bolt as a bearing surface against a floor of the socket. The containment socket has a slot there through at a position corresponding to the strap of the liner. The socket is provided with a disk-shaped recess having a flat floor, and the liner is provided with a distal flathead bolt having a flat head to provide a direct bearing surface against the floor of the socket. This provides a delimited bearing surface to keep the liner substantially centered within the prosthesis while still affording a lateral degree of freedom to avoid concentration of lateral forces.
