## Abstract

A bionic elastic fixing device relates to orthopedic medical devices, and is used to implement bionic elastic internal fixing for joint dislocation. The device consists of an elastic component (1) and a fixing assembly (2, 3, 4). The elastic component (1) may be multiple strip-shaped elastic mesh pieces, and has the assembly direction being the same as the ligament fibers at the joint required to be fixed. The elastic modulus of the elastic component (1) matches the elastic modulus of the ligament fibers at the joint required to be fixed. Two ends of the elastic component (1) are fixedly connected to the dislocated joint by the fixing assembly (2, 3, 4). The elastic component (1) has the same shape as the ligament fibers at the joint required to be fixed.
