Title:
ANKLE EXOSKELETON DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/130860
Kind Code:
A1
Abstract:
An ankle exoskeleton device (100) for helping a patient to relearn walking is disclosed. The ankle exoskeleton device (100) includes a leg brace (101), and insole (102), and a rotary actuator (400). The rotary actuator (400) is pneumatically driven to cause rotation of the insole (102) with respect to the leg brace (101) about a central axis (411). The rotary actuator (400) comprises first and second elastomeric structures (403A, 403B), a rotary shaft (402) rotatable about the central axis (411) to generate an output torque for producing a relative rotational movement of the insole (102), and a lever (410). The rotary shaft (402) is adapted to be moved by controlling two opposing fluid pressures inside the rotary actuator (400). The first elastomeric structure (403A) is extendable to push the lever (410) in a clockwise direction, and the second elastomeric structure (403B) is extendable to push the lever (410) in an anticlockwise direction, thereby the first and second elastomeric structures (403A, 403B) are arranged to control the rotary shaft (402).
