ORTHOPEDIC PART OF FOOT AND METHOD OF ARTIFICIAL FOOT CONTROL Russian patent published in 2013 - IPC A61F2/66 A61F2/68 

FIELD: medicine.

SUBSTANCE: group of inventions relates to orthopedics. Orthopedic part of foot contains connecting part for shin, acting as talocrural joint (7) rotary pivot (5), by means of which part (10) of foot is connected with connecting part with possibility of rotation in directions of dorsal and plantar flexions, influencing rotary motion around rotary pivot (5) shock-absorbing device (17), sensor device for determination of working conditions of orthopedic part of foot and connected with sensor device unit of shock-absorbing device control (17). Sensor device contains sensor of ankle angle, made with possibility of changing angle between connecting part and part (10) of foot, related to vertical sensor (20) of absolute angle and sensor (21) of moment for registration of torque in talocrural joint (7) or effort producing torque on talocrural joint (7). Method of control of said part of foot lies in the following: value, proportional to appearing on talocrural joint (7) torque, is determined, angle of ankle between connecting part and part of foot and absolute angle of part (10) foot with respect to vertical. Depending on said measured values control by means of shock-absorbing device (17) is performed over foot roll at the phase of support during walking, position of part (10) of foot at the phase of swing during walking and position and mobility of part (10) of foot during standing.

EFFECT: inventions provide possibility of controlling orthopedic foot in such a way that it meets larger number of requirements to its properties than before, by means of exclusively passive control over shock-absorption of motion around talocrural joint.
