Problems solved by technology

The specific structures of these limb joints are different, and the range of motion is also very different (some joints have a range of motion as large as 180° in a certain state, and some joints have a motion range as small as less than 20° in a certain state). It is difficult to simulate these limb joints through a specific structure

Abstract

The invention relates to an artificial human joint which comprises a first artificial bone connector and a second artificial bone connector. A joint ball seat is fixedly connected to the tail end of the first bone connector, a joint ball is fixedly connected to the tail end of the second bone connector, the joint ball seat is provided with a ball socket attaching to the surface of the joint ball, and the area of the surface covering the joint ball of the ball socket is smaller than one half of the total area of the surface of the joint ball. The joint ball seat and the joint ball are respectively made from a permeability magnetic material, and a magnetic attraction assembly is arranged in the joint ball seat. Under the magnetic attraction force of the magnetic attraction assembly, the joint ball seat and the joint ball are movably connected. The central axis of the joint ball seat coincides with the center of the joint ball. The central axis of the first artificial bone connector coincides with the central axis of the joint ball seat, and the central axis of the second artificial bone connector coincides with the central axis of the joint ball. The artificial human joint can achieve simulation of six main human limb joints through specific structures, meanwhile can ensure that crossing points of axes of bones connected on two sides of each joint are fixed, and high-degree simulation of the human limb joints is achieved.

Description

technical field [0001] The invention relates to a simulated human joint, which can realize a high degree of simulation of the human joint, and belongs to the technical field of bionic structure of a human body model. Background technique [0002] Bionics is an interdisciplinary subject, which mainly studies the structure, function and working principle of biological systems, so as to provide new design ideas and working principles for engineering technology. bridge. The continuous development of bionic technology will definitely promote the development of mathematics and engineering and other disciplines, thereby bringing huge social and economic benefits to society and promoting social development. [0003] Under the idea of ​​people-oriented, life is regarded as the most precious wealth in the world, and the study of ergonomics is particularly necessary. When studying the relationship between man-machine-environment systems, if it endangers people's health and life, it i...
