Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0052]A continuous control system for lower limb prosthetics driven by myoelectric signals according to the present invention includes a lower limb prosthesis 3, a myoelectric sensor 1 and a host computer 2;

[0053] The lower limb prosthesis 3 communicates with the host computer 2 wirelessly, and the myoelectric sensor 1 establishes communication with the host computer 2 wirelessly and sends the myoelectric signal to the host computer 2 in real time.

[0054] Specifically, the lower limb prosthesis 3 i...

Abstract

The invention provides a lower limb artificial limb continuous control system driven by electromyographic signals. The system comprises a lower limb artificial limb, a myoelectricity sensor and an upper computer, wherein the lower limb artificial limb comprises a receiving cavity, a thigh connecting rod, a knee joint, a shank connecting rod, an ankle joint and a sole; the myoelectricity sensor isfixed to the skin surface of a healthy side lower limb in a wearable mode; and the upper computer comprises a myoelectricity decoder and a controller, receives the myoelectricity signals from the myoelectricity sensor and generates continuous control instructions for the lower limb artificial limb. According to the lower limb artificial limb continuous control system, the problems that existing lower limb artificial limb related research is mostly focused on intention recognition, and research on how to convert a motion intention recognition result into a control instruction suitable for the lower limb artificial limb is little, are solved.

Description

technical field [0001] The invention relates to the technical field of lower limb prosthetics, in particular to a continuous control system for lower limb prosthetics driven by electromyographic signals. Background technique [0002] Due to traffic accidents, natural disasters, cardiovascular and cerebrovascular diseases and other reasons, tens of thousands of people lose their lower limbs every year, which brings a lot of inconvenience to their daily life and work. The current medical level is still unable to regenerate residual limbs, so prosthetics have become an indispensable tool for most lower limb amputees. Prosthetics can not only make up for the limb defects of lower limb amputees, but also help them regain some mobility. [0003] In recent years, in order to achieve a more natural and smooth control of lower limb prosthetics, the control method of lower limb prosthetics integrated with bioelectrical signals has gradually become a research hotspot. Relevant studie...
