Description

Combined support Technical Field The utility model belongs to the technical field of bone correction, and particularly relates to a combined bracket. Background The human body has 206 bones which are connected with each other to form skeleton bones of the human body and are divided into 3 major parts of skull, trunk bones and limb bones, wherein, the skull comprises 29 parts of skull, 51 parts of trunk bones and 126 parts of limb bones, skeletonization is the basis of complicating biological structures, skeletal systems are the limiting factors of biological morphological evolution, and the skeleton is a hard organ forming the skeleton of the vertebrate bone and has the functions of moving, supporting and protecting the body, manufacturing red blood cells and white blood cells and storing minerals.
