Problems solved by technology

These intelligent prostheses above basically use the detection signals of the prosthesis itself to control the hydraulic or pneumatic dampers, which not only cannot simulate the actual normal gait, but most of the limited gait control also requires complicated training to obtain the target parameters of the control , inconvenient to use, its essence is not really a real-time bionic intelligent prosthesis

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] As shown in Fig. 1, an intelligent above-the-knee prosthesis system that follows the pace control of healthy legs includes: a prosthesis 100, an electro-hydraulic knee joint 200 that can be flexed and extended with two-way damping adjustment, and a healthy knee joint installed in the healthy leg joint. Leg gait online detection mechanism 300, gait data transmission system; computer control system for controlling prosthesis to follow walking speed and mode adaptation.

[0031] The healthy leg gait online detection mechanism sends the gait data of the healthy leg as the following target value of the prosthesis to the microprocessor in the prosthesis through the gait data transmission system, and the microprocessor calculates the angular velocity of the healthy leg through signal analysis. target volume for prosthesis following;

[0032] The comput...

Abstract

An intelligent on-knee artificial leg system able to control the walking speed for synchronizing it with health leg is composed of an artificial leg with a microprocessor, an electrically controlled hydraulic knee joint, an in-line detecting mechanism for detecting the steps of health leg, a step data transmission system, and a computer control system. Its control method is also disclosed.

Description

technical field [0001] The invention relates to an above-knee prosthesis in medical equipment engineering, in particular to a microprocessor-controlled above-knee prosthesis system which follows the gait of healthy legs. Background technique [0002] Traditional prosthetic legs with locks or load-bearing self-locking knee joints are not easy to change their motion state, especially during the swing process, they cannot control the damping of the knee joint to control the change of swing speed, so they cannot simulate the normal gait of the human body, and cannot perform well Adapt to complex environments such as downhill, stairs, and tripping. With advances in computer technology, above-the-knee prosthetics have continued to improve in recent years. The intelligent knee prosthesis can automatically adjust the damping of the knee joint due to the use of microprocessor control, thereby approximately simulating the gait of human legs. How to make the p...
