[0027] Traditional lower limb prostheses are mainly passive prostheses, which rely on the swing of the residual limb to drive the movement of the prosthesis during walking to achieve alternate walking, and the user consumes a lot of energy. However, purely active prosthetics generally use motors as the actuators to drive joint flexion and extension movements. Since the motors need to run continuously during the joint movement process, and require a large driving force when standing up, going up and down stairs, etc., the power consumption is extremely high. The problem of power supply has become a bottleneck that is difficult to break through at present. Therefore, the lower limb prosthesis with active and passive hybrid drive has become a new research direction at home and abroad. How to set the active control mode and passive control mode, and how to judge when to use which control mode is a key problem that needs to be solved. The problem of type identification. In order t...

Abstract

The invention provides a limb prothesis control method and device and a storage medium and belongs to the field of medical treatment. The limb prothesis control method comprises: first, acquiring effective action signals of actions made by a user's limbs, recognizing current motion types of the actions based on the effective action signals, and controlling limb protheses connected with limbs to bein current matching control modes matched with the current motion types, wherein the current matching control modes include an active control mode or a passive control mode. In the active control mode, the limb protheses supply power to drive the limbs to move; in the passive control mode, the limbs supply power to drive the limb protheses to move. Energy consumption level of a user's actions isused as a standard to control the limb protheses to be in the active control mode or the passive control mode, and power consumption of the limb protheses is lowered.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a prosthesis control method, device and storage medium. Background technique [0002] With the improvement of humanistic literacy and the development of social economy, society pays more and more attention to vulnerable groups, especially the degree of care for the disabled. At the same time, in the world, prosthetic technology is constantly developing from low-level and simple to high-level and complex with the progress of society and science and technology. Advanced prosthetics use more advanced technology and materials to make them have more perfect performance. Since the 1990s, prosthetic technology has developed towards a high-tech direction that is more precise, more comfortable and more in line with individual requirements. Nowadays, the development of science and technology has made prosthetic medical devices more and more perfect. High-tech prosthetics can almost...
