SYSTEM FOR CONTROLLING ARTIFICIAL KNEE JOINT ACTION IN AN ABOVE KNEE PROSTHESIS

摘要

The present invention relates to an automatic control group for applying a hydraulic damper to control the angular velocity, ie the rotational speed of the artificial knee joint.;In the present invention, the programmed microprocessor recognizes a general auxiliary pattern from the information output from the strain load and the joint angle sensor of the prosthesis.;The microprocessor operates the motor to control operation at various state transition points while walking, and the motor controls the valve assembly.;The valve assembly is capable of variable and separately damping, i.e., damping, vibration of the knee joint during bending and extension of the knee joint.;According to the present invention, since the operation control of the knee joint is considerably improved, the walking type of the foot wearer, that is, the appearance of walking, is greatly improved, and the foot wearer can easily perform operations such as going down the stairs or sitting. .
